About This Guide


Preface
This guide was created to help you understand the philosophy behind Motorola's Enterprise Wireless LAN (EWLAN) products. This guide is intended for those interested in familiarizing themselves with the Enterprise wireless offerings available from Motorola. Additionally, once familiar with Motorolas solution set, this guide also explains how to plan and assist in the deployment of your wireless network in respect to emerging standards and technologies. Once you have thoroughly reviewed the content of this Enterprise WLAN Design Guide and applied it theoretically to the tenorshare icarefone 5.6.0 crack - Activators Patch 802.11n standard (as described within 802.11n), you will have all the pre-requisite knowledge required to plan the replacement of an existing wired network and deploy an Enterprise-class wireless network. NOTE: Please keep in mind, successfully deploying typing master pro crack 2019 - Free Activators wireless network is directly related to successfully defining the user requirements, physical obstacles, growth expectations and emerging technologies both impacting your deployment now and in the future. The guidelines set forth within the guide will help prepare you to ask the right questions when faced with these decisions. The graphical interfaces of Motorolas Enterprise WLAN products are designed intuitively. With just some basic knowledge of 802.11 wireless technology, you can plan, deploy and manage your infrastructure. All of Motorola's EWLAN products follow this philosophy of keeping things simple to optimize your deployment. Motorola has observed that trying to push through your own Command Line Interface (CLI) is not really the best thing to do when you know there is a very strong CLI becoming a standard in the industry. Therefore, Motorola is moving its products to this type of CLI. To date, the WS5100, RFS6000 and RFS7000 are already using Motorolas proprietary Wireless Next Generation (Wi-NG) technology.

Introduction
Installing a wireless network within an organization entails allot more then just performing a site survey. In fact, a site survey is just a small part of a wireless deployment. A better convention for the planning and deployment of wireless network is wireless system design. NOTE: This guide was created to help you understand the philosophy behind Motorola's Enterprise Wireless LAN (EWLAN) products. This guide is intended for those interested in familiarizing themselves with the Enterprise wireless offerings available from Motorola. Additionally, once familiar with Motorolas solution set, this guide also explains how to plan and assist in the deployment of your wireless network in respect to emerging standards and technologies. A good wireless system design entails the following: A site survey Channel mapping An understanding of the construction of the building An understanding of where RF coverage is required The esthetical position (corridors, isles and coverage area blockages) The number of users per AP The required throughput per user The distance from an AP to the LANs entry point Power supply options Security options The location of the Radius Server (acceptable RTT yes/no) Understand if the applications are wireless ready NOTE: Many protocols are designed for a wired environment where there is almost always a connection between the terminal and the server, whereas in a wireless environment the terminal can go in and out of RF coverage or go into sleep mode and loose its connection with the server. A proper site survey is much more involved then just measuring RF coverage. That is why a more appropriate description might be system design. To add mobility in an Enterprise, conduct a complete wireless system design in is respect to the intended mobility features. To design mobility within an Enterprise, conduct a complete wireless system design with respect to the mobility features planned.

WLAN Reference Architectures


2.1 History and Innovation
No entity has a stronger heritage in wireless than Motorola, and with the acquisition of Symbol Technologies, no one else can claim as much experience, innovation, or intellectual property in wireless communications. Motorola has been involved in RF for over 75 years, significantly longer than any of our competitors have been in business. Motorola's wireless communication systems were used by the Apollo astronauts when man first stepped on the Moon Motorola is chosen more often than any other vendor for large scale, secure mobile communications systems at international events like the Olympics, NFL games and NATO Summits Motorola was the 2006 winner of the National Medal of Technology - America's highest honor for innovations Motorola is a two time winner of Malcolm Baldrige Award - US Governments highest quality award Motorola is a leading provider of mobile data communications in the State & Local and Federal Markets Symbol Technologies was the leader in WLAN innovation, with a long list of industry firsts and contributions: 1989: Brought to market the first commercial WLAN - the Spectrum 1 1993: founding members of the IEEE 802.11 committee 1998: Introduced the first wireless VoIP handset - the NetVision phone 1999: Founding member/chair of the Wi-Fi Alliance 2002: Invented the WLAN switch (controller) architecture 2007: Began shipping the industry's first RF switch (the RFS7000)

2.2 WLAN Market Leadership


Motorola is the best kept secret in WLAN infrastructure solutions. Many of our prospective customers are not aware of our position in the marketplace. If we have a weakness in our past, it certainly isn't technology, but rather our focus on marketing it. Motorola's customer base includes many of the worlds largest retailers, health care institutions, transportation companies, and manufacturers - to name a few - all of whom rely on a Motorola backbone for their mission-critical mobility needs. Billions of dollars in business is transacted across our networks every

2-2 WLAN Design Guide

year. If the stores or distribution centers of just one of our largest customers were to go down, there would be a very real material impact on the world economy. A few facts: Over 100,000 WLAN switches sold - 2 times more than Cisco, the next closest competitor #1 or #2 in WLAN revenue in many key vertical markets: retail, health care, manufacturing, transportation and logistics. Bottom line: we win where we play. Largest WLAN deployment in the world with 100,000 APs and over 10,000 switches Largest wireless VoIP deployment with 40,000 Spectralink phones on our WLAN

2.3 End-to-End
Motorola provides the most comprehensive end-to-end Enterprise mobility solutions available in the market. Why is this important? CIO's increasingly like to buy from fewer and fewer manufacturers. They want fewer vendors in their account - thus, fewer necks to squeeze when there is a problem. Additionally, they want solutions that work well together, and thus are more easily managed avast premier 2019 crack - Crack Key For U secured. Solutions sourced from a single vendor are far more likely to work together seamlessly. Motorola offers solutions that span the entire range of Enterprise mobility. From where the network cable terminates, to the palm of the hand and beyond, from wireless infrastructure indoors and out, private networks and mesh technology, to mobile computing, advanced data capture, RFID, and management and security software, Motorola provides complete end-to-end Enterprise mobility solutions that no other single vendor can match. Our competitors can easily be reduced to one-trick ponies or simply blue wire or plumbing. No one offers the industry expertise, or the breath of solutions and technology to provide true mobility. Motorola is a leader in the various aspects of mobility: #1 in mobile computing, data capture, RFID, wireless broadband, two-way radios, and push email.

2.4 Edge Versus Core


Imagine for a minute the entire ecosystem of IT investments that one of your prospective customers will make to mobilize their business. The list is long, but it minimally includes: IP Core Access Networks Clients, Switches, WLANs, Mobile Computers, Routers, Cellular, Rugged Laptops, Firewalls, WiMax and Wireless VoIP Handsets Motorola focuses on wireless networks and client devices. We have tremendous experience in mobility and our portfolio includes a strong set of solutions focused on the network edge. Our competitors, on the other hand, tend to focus on the core, or even worse, only a single element in the ecosystem. To provide true mobility, a vendor must understand every piece of the mobile edge. How will your devices roam - between APs, indoors to outside, or from WLAN to WiMax? Can you manage your WLAN network and point-to-point broadband network seamlessly? How will you secure your mobile infrastructure and devices to ensure regulatory compliance and protect sensitive information? Motorola coined the phrase Enterprise mobility by being the first to truly unwire the Enterprise and enhance productivity for the mobile worker. Doing so, required enormous amounts of innovation and expertise. A mobile environment requires a unique level of management, security, and control. Through a broad portfolio of wireless infrastructure solutions (not just WLAN), as well as market leadership in mobile devices, only Motorola truly understands mobility throughout the mobile edge.

2.5 Enterprise Class Versus SOHO Class Products


In terms of the differences between an Enterprise class and a typical SOHO class product: a. Our infrastructure products are optimized to support mobile applications and devices. This includes functionality such as Pre-emptive Roaming/Load Balancing, Power Save Protocol, Virtual AP (Multi BSSID support for broadcast domain separation over the air), Proxy ARP, etc. b. Enterprise class security including support for WPA2 (and fast roaming options such as PMK caching) and integrated AAA Server for local authentication - this precludes the need for an additional AAA / RADIUS server, lowering the cost of deploying Enterprise class Wi-Fi network in branch offices. We support Rogue Adobe character animator mac - Free Activators detection (which none of the SOHO class product do). The AP-5131 and WS2000 also support integrated Stateful Packet Inspection Firewall and site-to-site IPSec VPN. Both products today support the provisioning and operation of secure guest access (hotspots). c. Comprehensive remote monitoring and management capabilities including SNMP v3. Support for SNMP traps on various events RF health monitoring (very important for deployments in branch offices) Syslog with different log levels d. Features that support auto update of configuration / Firmware files (again, very important for deployments and management in branch offices). e. QoS support and support for evolving standards such as Wi-Fi Multimedia (WMM). Our infrastructure also supports packet prioritization and wireless bandwidth management. We have SpectraLink VIEW and Avaya DevConnect certification. The WS2000 supports SIP Call Admission Control. None of the SOHO products can lay claim to supporting voice with QoS. f. The WS2000 supports up to 6 access ports; 200 MUs per switch. A WS5100 is capable of supporting up to 48 APs. Most SOHO class products pale in comparison in terms of performance. g. Wired network integration (WLAN - VLAN mapping and auto assignment of VLAN IDs based on user authentication). We also map wired network prioritization as well (802.1p; DSCP). h. Ruggedized design (of APs). Support for multiple antenna options. i. Support for wireless bridging / mesh (AP-5131 currently supports it today) j. High MTBF (>60,000 hours) k. The backing of Motorola Services for extended product services/warranty, technical support, advanced exchange, etc

2-4 WLAN Design Guide

2.6 Inside Out


Motorola has the strongest and most-complete portfolio of wireless infrastructure solutions for inside and outside the four walls. Motorola has an advantage with customers that have outdoor wireless requirements (point-to-point connectivity, outdoor or campus-wide coverage, seamless connectivity indoors and out). Our outdoor broadband products and mesh capabilities are the best in the industry. The Canopy product line is a solid number one in the unlicensed broadband market. The ability for a customer to go with one vendor for both indoor and outdoor connectivity makes Motorola the clear leader in this space. For more information on Motorolas Canopy line, see Canopy Systems on page 9-1.

2.7 Differentiators
Differentiators for Motorolas WLANs include: Lower Cost of Ownership Redundancy and Business Continuity RF Switching Wireless Intrusion Detection End-to-end Design and Management Voice Capabilities Ease of Use

2.7.1 Lower Cost of Ownership


Motorola provides a reliable, scalable infrastructure and cost-effective infrastructure solution. Other vendors often hide costs, initially positioning features and functionality that is separately licensed. With Motorola, there are no hidden costs. Combine that with our smart licensing and zero-port licensed switches for competitive price points. Included at no-extra cost: On-board firewall support VPN endpoints IDS / rogue detection A locationing engine Adaptive AP (AAP) support Hotspot / guest portal support

NOTE: Be sure your customers are comparing apples to apples when showing them the low cost of our products. Our competition has been known to bait and switch, effectively hiding the cost of additional features up front.

2.7.2 Redundancy and Business Continuity


Only Motorola offers wireless redundancy in a cost-effective manner. Support for multiple levels of redundancy and failover capabilities ensure an always on highly available network for superior performance.

WLAN Reference Architectures 2-5

Zero port licensed switches, redundancy without the cost of a fully licensed switch Load balancing utilizes redundant switches in day-to-day operation to take advantage of the otherwise unused capacity Switch clustering combines two or more switches into a single management point to provide failover and unmatched capacity

2.7.3 RF Switching
Having strong investments in a wide variety of wireless technologies is a strong differentiator for Motorola. While our competitors offer only WLAN, Motorola can provide infrastructure solutions across a multitude of standards: Wi-Fi, RFID, WiMax, UWB, etc. Motorolas RFS7000 (first launched in 2007), provides a scalable platform that supports multiple RF technologies, not just 802.11. This gives our customers the ability to manage multiple wireless networks with a single switch, thus providing investment protection as an alternative to rip and replace. The ability to easily upgrade the system to support new standards and features and to scale to meet capacity requirements as a company grows ensures the system you sell your customers today can continue to meet their needs tomorrow.

2.7.4 Wireless Intrusion Detection

Virtual AP provides broadcast domain separation over the air improving security and manageability of wireless LAN traffic, and also works together with Power Save Polling (PSP) to optimize the battery life of client devices.

2.8 Motorola on Motorola Advantages


Motorola on Motorola is a term that describes the use of Motorola hand helds within a Motorola WLAN infrastructure. Since the creation of the standards body, many customers (even Motorola employees) feel equipment that is standards based can work perfectly with other standards based equipment. To a degree this is true, but much of the focus of the standards body is not at the level Motorola needs it to be. Many features have been enhanced to allow better performance within a complete end to end Motorola installation. They include:

2.8.1 Advanced Load Balancing


Motorola wireless clients maintain a table of APs in their vicinity and log their respective load information. The AP passes on the loading information to the clients. To keep this table up-to-date, Motorola wireless clients do periodic full scans. This table is then used to make roam decisions to better spread the load on one AP to other APs in the vicinity. Motorola clients use a sophisticated load-balancing algorithm when too many clients attempt to connect to a particular access point. The clients use a beacon element to perform pre-emptive roaming and load balancing, thereby moving from a heavily loaded AP to one that is less loaded. Motorola's wireless switch systems allow wireless devices to roam to a less busy access port when the existing connection quality deteriorates due to excessive network traffic. The switch sends load information to wireless devices so dynamic load-balancing decisions can be made when needed. The wireless switch video editing software 64 bit - Crack Key For U fast roaming within a WLAN, to maintain real-time voice and data connections and application performance. The switch sends information used by wireless devices to make roaming decisions before the existing connection deteriorates. Motorola's wireless switch products can be configured with maximum thresholds that govern the number of devices that can be connected to each AP; therefore ensuring no one AP is overloaded and any new devices will have to find a less busy access point connection. Dynamic load balancing is accomplished by including load indicators in the beacons sent by APs (as directed by wireless switch). Two types of load indicators are sent: Symbol/Motorola proprietary as well as 802.11e standard specific. Motorola wireless clients can use this load balancing information to auth/associate with the AP best suited based on load and RSSI. The elements used in Symbol/Motorola Proprietary mechanism include 2 byte: Kbps (traffic load indicator) and 2 byte: MU Count.

WLAN Reference Architectures 2-7

The QBSS load element used in 802.11e includes 1 byte: air channel utilization % and 1 byte: MU count. NOTE: The only restriction for load balancing is that it works only when clients make use of the fields for load balancing.

2.8.2 Pre-Emptive Roaming


Clients roam to the best available access port/point based on the information sent by the switch. Clients also attempt to automatically load balance across access points based on the load balance element in the frame sent by the AP. The roaming mechanism implemented on Motorola wireless products (mostly on the client, with support on the AP) was designed to meet the mobile requirements of handheld wireless device users. The idea is that the choice of the new AP is made before the existing connection is lost or deteriorates too much. A typical 802.11 device, scans every channel (full scan) after it loses its existing connection to find new APs and blindly roams to a new AP irrespective of the quality of new connection. Motorola clients use the RSSI, percentage of missed beacons, and drop in RSSI as thresholds (hard-coded in firmware) to indicate deterioration of service. If at anytime, the existing connection deteriorates below any of these thresholds, the Motorola wireless clients supplant the roam by doing a full scan before it actually loses its connection. In fact, these thresholds are high enough so a minimum level of service is maintained at all times. During a full scan, Motorola wireless APs forward load information in the proprietary part of the 802.11 frame. Therefore, clients can make educated decision on which AP to initiate a roam with. The benefits of pre-emptive roaming and secure fast roaming can also be extended to clients roaming across a campus (or IP domains). The overlay architecture of the wireless switch and AP300, allow for seamless roaming across each building in the campus. Since device traffic from each building (IP domain) is tunneled back over the access port to the wireless switch, devices moving from one building to another (or one IP domain to another) do not need to renew their IP addresses and continue to communicate with a disruption in service. Roam times of <50ms can be maintained even when roaming across IP domains.

2.8.3 Client Assisted Rogue AP Detection


Motorola clients provide information to the infrastructure on the APs they see as they roam across the network. This provides better visibility to any rogues devices that might jeopardizing security in the network.

2.8.4 Security Optimizations


Network Time Synchronization (NTP) allows Motorola clients to automatically synchronize system time with the network allowing for 802.1x authentication.

2.8.5 Hyper Fast Secure Roaming


Hyper Fast Secure Roaming (HFSR) is roaming on a switch that is faster than 802.11r and WPA2 for all security mechanisms (including non credential caching authentication). If a client is authenticated and remains on a current switch, no re-authentication is conducted between APs. Key features (differentiators) of HFSR include: Motorolas Enterprise WLAN products support a patented proprietary extension to the current IEEE 802.11i specification known as HFSR. This mechanism off loads the key handshake mechanism used by 802.11i encryption standards resulting in hyper-fast seamless roaming

2-8 WLAN Design Guide

Handshake messages are used to derive a new Pairwise Transient Key (PTK) and Group Transient Key (GTK) HFSR overloads 802.11 association messages between the mobile client and the AP to carry out the handshake mechanism The entire roam is carried out without doing EAP over LANs EAPOL key handshake messages. thereby improving roaming handoff times (making it ideal for voice applications) The current 802.11i standard defines two ways to perform fast roaming; PMK key caching and pre-authentication. Most vendors support an extension to PMK key caching known as opportunistic PMK key caching. The drawbacks of these three standards include: No support for Pre-shared key Authentication 802.1x supplicant is not available on all clients 802.1x Radius is not a viable option always 4-way or 6-way EAPOL key handshake still needs to be performed Not desirable for VOIP Applications Not power save friendly

2.8.5.1 Theory of Operation


Motorola Enterprise WLAN products support HFSR within their 802.11 management frames. Motorola clients add a proprietary HFSR Information Element (IE) in the 802.11 re-association request containing the current PTK hashed (HMAC-SHA1). The wireless switch verifies the validity of the PTK and adds the proprietary HFSR IE in the 802.11 association response containing HFSR roam status and new GTK and Receive Sequence Counters (RSC). Both GTK and RSC are encrypted using the underlying encryption method in the association request (RC4 or AES-CCMP). MUs decrypt the new GTK and RSC and windows download tool - Free Activators to use the current PTK and the new GTK. A user configurable PTK validity life time is provided to prevent PTK from being compromised For 802.1x MUs, user configurable re-authentication intervals ensure the PTK cache lifetime is controlled. This 802.1x Re-Authentication option is already available on all Motorola WLAN Products. Non HFSR compliant MUs are allowed to co-exist in Motorola's HFSR enabled infrastructure, since the wireless switch invokes the HFSR only if initiated by the MU.

2.8.5.2 Advantages of HFSR


Key advantages of HFSR include: Hyper fast roam times can be guaranteed, making HFSR an ideal choice for voice applications requiring WLAN infrastructure Fewer message exchanges make HFSR very less susceptible to roam failures HFSR is secure since it extends the existing 802.11i standard to a level higher HFSR has a user configurable key life time HFSR is an authentication independent solution - rendering 802.1x as not mandatory No configuration modifications are required on the client side, all control resides on a centrally managed wireless switch or wireless switch cluster

2.8.6 Voice Optimization


Smart scans reduce the amount of scanning time from the AP. Using voice load balancing, an AP supplies load information in the access category of the beacon. With optimized load balancing, abbreviated AP back-offs for voice devices are identified via a WNMP message.

2.8.7 Location Optimizations


Radios can be configured with custom messages. Any MU that associates with that radio is provided with that message. All Motorola WLAN Products shipping today support a legacy Motorola proprietary element in the 802.11 management frames The purpose of this proprietary element is to ensure MUs use the advertised information in the proprietary element to make intelligent roaming decisions The Motorola proprietary element ensures roam quality, not roam speed, as roam speed doesn't always guarantee an optimal user experience if the roaming decision is flawed The proprietary element facilitates load balancing based on: Client capacity per AP RF activity and bandwidth usage per AP MUs use advertised values in the proprietary element to perform pre-emptive roaming.

Understanding WLAN Connectivity


4.1 How MUs Associate to an Access Point
Whether a MU is associating to an AP-5131 or an AP300 (connected to a wireless switch), the MU association process remains the same. In fact, to make the association process as transparent as possible, the association process is almost 100% standards based. However, an MUs decision to choose an AP can be made using some additional proprietary mechanisms in the AP's beacons and the driver in the MU radio. For security, extra functionality should be added to the wireless switch to control if an MU has WLAN access, based on a users credentials, time, or other parameters in respect to business needs. Lets take a closer look at how an MU associates to an access point (with or without security) and the additional Motorola advantages designed to optimize the association process.

4.1.1 The MU Association Process


The MU association process can be viewed (at a high level) as the following sequence of device interactions: MU -> probe request -> AP AP -> probe response -> MU MU -> authentication request -> AP AP -> authentication response ->MU MU -> association request -> AP AP -> association response -> MU

4.1.1.1 Probe Requests


A probe request is a broadcast message serving the following two functions: A probe for the ESSID needed for connection A probe for the supported data rates of the AP targeted for connection

4.1.1.2 Probe Responses


A probe response has almost the same information as a beacon, the only difference is a beacon is a broadcast message and a probe response is a unicast message to the terminal initiating the probe request. The following values should be considered in a probe response: Supported data rates form the AP point of view SSID Country ID this is the support of 802.11d QBSS load to support 802.11e ERP information to support 802.11b/g NOTE: When WPA2/CCMP (802.11i) is enabled, there is an extra element in the probe request called Robust Security Network (RSN).

The Symbol proprietary element is present to help Motorola MUs make a better decision as to which AP to roam to. Symbol proprietary extensions define:
Number of clients: 0

Ensures an equal number of MUs are attached to APs as seen from the MU's point of view.
Load (kbps): 256

Indicates the throughput of the AP during the probe request. Very important metric for defining the QoS.
Load (kpps): 2560

Indicates the amount of packets per second the AP is processing during the probe request. Very important metric for defining the QoS.
Tx power: 0

This parameter is for advanced power control over the MU. It is not good when an AP is set to 1mW and all the MUs are still operating at 100mW. In this case, the Adobe acrobat dc vs pro - Crack Key For U will suppress the AP signal and there is instability in terms of associated users on respective APs.
ntp time: 0

This is a time field used to update MU time. This option is very important when the auto deployment of MUs is requested in combination with authentication. Authentication is always time based, and not all MUs are have the current time when deployed out-of-the-box. Therefore, this parameter ensures the MU can adopt to the WLANs time.

4.1.1.3 Authentication
The authentication portion of the association process is not in parallel with 802.11i, as 802.11i process kicks in after association. Authentication produces the following: Authentication algorithm number - When this is zero there is open authentication or no authentication at all. When this is one, there is shared authentication. This means that the MU and AP will follow a protocol of hashing a text with the shared WEP key to find out if they are who they say they are. Better Authentication methods are available today in the form of 802.11i. Authentication Transaction Sequence Number Status Code - Provides feedback on the progress of the selected authentication method. NOTE: De-authentication is often used in IPS systems. De-authentication is a much more aggressive way to kick a rogue MU form the network then de-association.

4.2 BSSIDs versus ESSIDs


BSSID - Basic Service Set ID ESSID - Extended Service Set ID Compare an ESSID and BSSID with the MAC address of a PC and the DNS of the PC. It all comes down to the same principle. All devices connected to a network can only talk to each other when their respective MAC address is known. However, people are not good at remembering MAC addresses. Consequently, naming each PC and User is needed. These are often the same names as the ESSID and BSSID. One BSSID is the radio MAC address of a single AP. In theory if you have one AP, you should be able to connect to this AP by configuring the MU with the BSSID of the AP. The problem is when you have more then one AP, and you want to be mobile. How can you determine the MAC addresses of potentially 10 APs (available for association) in such a mobile environment? You will have to determine the BSSIDs of 10 APs! An ESSID provides assistance. An ESSID (Extended Service Set ID) is a group of BSSIDs with the same common name. This name is most often the ESSID or SSID of the configuration software of the AP. When the ESSID is configured in an MU, the radio driver of this MU will use this name to determine (via Probe Requests) if there is an AP in the area of this ESSID.

4-12 WLAN Design Guide

When the MU discovers an AP with this ESSID, it will associate to the BSSID of the AP. NOTE: An MU only communicates to the BSSID, not to the ESSID. The ESSID is generally used to retrieve the BSSID of an AP belonging to the ESSID. This is why there are three MAC addresses in the header of an 802.11 wireless trace instead of 2 MAC addresses like in an 802.3 wired trace. Source address - the address of the source device (mainly the MU, server or router) Destination address - the address of the Source Device mainly the MU or the Server or Router ESSID - the MAC address of the wireless distribution device, the device of which the Mobile Unit is communicating through to the wired network.

Multiple ESSID support is available on the access point.

4.3 VLAN to ESSID Mapping


WLANs are becoming more and more popular. The concept of copying the functionality of a wired LAN to a wireless LAN is real. Therefore, trunking (802.1q) technology is added to APs and switches. This enables AP to map VLANS to WLANS (in other words VLANS to ESSIDs). This is done is differently depending on the manufacturer. Imagine the following scenario: You have 4 VLANS, and you want to map them to 4 ESSIDS. Remember a MU can only communicate with a BSSID. In this scenario you have 4 ESSIDS in the AP mapped to one single BSSID. This means the broadcast and multicast traffic coming from the 4 VLANS is sent (in the air) with the same BSSID. Disadvantages of this scenario include: Reduced battery capacity for MUs - The MU has to listen to broadcast and multicast traffic coming from the 4 VLANS. Reduced security options - For example you have configured one VLAN for WEP security and one VLAN for WPA2/CCMP. The whole network is only as secure as the weakest security mechanism in use. Reduced QoS - Resulting from an overhead in a specific users VLAN traffic in the user's respective WLAN. For example, when using one VLAN for VoWLAN (Voice over WLAN), the voice application has to

Understanding WLAN Connectivity 4-13

share the BSSID with 3 other VLANs, in worst case, the 3 other VLANS can occupy all the available bandwidth with the consequence there is not enough room for voice traffic. NOTE: MUs in Power Save Mode (PSP) have to wake up to listen to a broadcast traffic. Since multicast is seen as broadcast, the MU must listen to the multicast traffic coming from that BSSID. In respect to the switch wired LAN, the WLAN is a large collision domain where the VLAN traffic is broadcasted over the WLAN. NOTE: A current trend is having one ESSID, and assigning the respective VLAN to the user through Radius authentication. This is tempting, and simple to do, but not suitable for a mobile environment. When integrating this type of service, you have 1 ESSID mapped to 1 BSSID. All the broadcast and multicast traffic of the available VLANS is sent in the air (with all the disadvantages that entails). The solution to overcome this issue is called Multi BSSID (or as some manufactures call it, Virtual AP).

4.3.1 Multi BSSID


Multi BSSID coverts an AP into 4 virtual APs with 4 BSSIDS per radio. 4 BSSIDs for the 802.11b/g radio and 4 BSSIDs for the 802.11a radio.

BSSID 3: CC:CC:CC:CC:CC:CC ESSID 3: Facilities & Security BSSID 4: DD:DD:DD:DD:DD:DD ESSID 4: Guests & Visitors

Using a wireless trace, multi BSSID could appear as follows:

4-14 WLAN Design Guide

In this trace you see that the same AP is sending on 4 BSSIDS namely 00:15:70:65:A3:60 - *:61 - *:62 - *:63 Using Multi BSSID, map up to 4 WLANs to 4 BSSIDs, granted you still share the same collision domain in respect to the RF channel used by that AP. However, the user is seeing only the traffic coming from his VLAN and the traffic from the other VLAN(s). Consequently, you should: Increase battery life - The MU has to wake up for broadcast and multicast traffic coming from his WLAN. Increase security - Since you segment the traffic, you can also size the security. In other words, a WLAN/VLAN using WEP will not affect the security of a WLAN/VLAN using WPA2. Increase QoS - If deploying VoWLAN, the devices connected to this WLAN/VLAN will not have the annoying overhead broadcast and multicast traffic coming the other VLANs, and have room to make a voice conversation.

4.3.2 Multicast over WLAN


Audio and video are just two of techniques that blend multimedia and networks. Packets can be send at an uneven rate and order. Multimedia requires data packets arrive at the client on time and in the proper order. We all know the differences between wired and wireless networking. One of these differences is the way multicast is handled by an access point. With the arrival of Motorola's wireless switch technology, new challenges arise from the integration of multicast streaming services in the wireless switched environment.

4.3.2.1 Why do You Need Multicast?


Multimedia requires data packets arrive at the client on time and in the proper order. The same is true for wireless environments. The sections that follow explain how to implement a wireless multicast mechanism. The main reason for configuring the multicast mask is the Delivery Traffic Indication Messages (DTIM). The DTIM determines how often the MAC-layer forwards multicast traffic. Mobility requires the DTIM parameter to supply the battery life to a terminal. By default, the DTIM in within Motorolas switches is set to 10. This means an access port will save the multicast packet for this BSSID and send the respective packet/frames after every 10th beacon. Having smaller DTIMs delivers multicast packets in a more timely matter. The disadvantage is MUs in PSP mode will wake up more often, with a negative battery drain being the consequence. With a large DTIM, the

Understanding WLAN Connectivity 4-15

multicast will have larger delays with a direct result of bad streaming video quality. Consequently, you need a multicast mask.

Within the wireless trace above, packet 71 is the beacon with the last DTIM count: 0 This message, in combination with Bitmap Offset: 1 (which is a bug in Airopeek, it should be Traffic Ind: 1), warns the MU there is/are message(s) waiting for it. As a result of the message, the MU will wake up and receive the two multicast packets. Why two packets? That's the buffer size of the AP100 used in this scenario. The data rate for management packets (beacons) is different for the multicast packets. Management packets are sent at the lowest possible basic data rate. Multicast packets are sent at the highest possible basic data rate.

4.4 Securing WLANs using Motorolas EWLAN Products


As stated previously, the functionality and integration of Motorolas EWLAN products is more or less the same. Whether it is an AP-5131 or a RFS7000 deployment, the configuration and integration philosophy is identical. This is also true for integrating wireless security The following table represents security possibilities per product:

Motorola still supports WEP. However WEP is becoming less significant and we haven't included it into our list of supported security mechanisms.

Understanding WLAN Connectivity 4-17

4.4.1 Integrating Motorola EWLAN products with an External Radius server


Aside from PSK, an external Radius server is the simplest means of integrating security to protect WLAN data. A Motorola WLAN device can operate as a Radius Proxy server and forward authentication traffic coming from an MU to the Radius server defined in the configuration of that specific WLAN. You do not need to configure an EAP-type since it is provided to the Radius server by the MU. The Radius server then checks if it supports the EAP-type received from the MU. Its this flexibility that makes Radius integration with Motorola infrastructure so easy. It doesn't matter if it is Microsoft Radius, Steel Belted or Cisco ACS you connect to them all via the Radius port. Be careful with the Cisco ACS. Cisco is not using the default Radius port (1812) for authentication and1813 for accounting. Cisco uses ACS 1645 for authentication and 1646 for accounting. If configuring Radius parameters on Motorolas EWLAN products using Cisco port numbers, the integration should be somewhat seamless. NOTE: It is possible (for security) a company is stepping away from ports 1812, 1813 or 1645 and1646. It is always good to ask an on site professional for these port settings.

For redundancy, configure a secondary Radius server. The following are examples of how to configure a Radius server on an AP-5131 and a WS2000.

Securing the Wireless Enterprise


The ubiquity of WiFi has meant that increasing amounts of corporate and personal data is being accessed and transferred over the wireless medium. This leads to uninterrupted access to information whether at home, on the road or at the corporate office, and provides significant productivity gains. However, it also exposes valuable data to the unsolicited and malicious intent of hackers. The fact that sensitive information is available on air, and can be accessed from outside the confines of the office or home, makes tackling WLAN security very challenging. It is important the possibility of data theft is checked to prevent productivity and financial loss. Security protocols, if implemented and used effectively, can prevent data theft (owing to strong encryption and authentication algorithms), but they still leave a lot to be desired. An attacker can still launch a Denial of Service (DoS) attack to deny resources to a valid user. Or, a My Notes Keeper 3.9.3 Build 2206 Crack + Serial Code Free 2021 user can access the resources beyond what they authorized. A malicious visitor or a careless employee can jeopardize corporate resources if their actions lead to a backdoor entry to the network by a rogue AP. An employee returning from vacation could jeopardize the network because their Virus resources may not be up-to-date. By the time they connect to the corporate WLAN and update their laptop, it could be too late. Checks based on a user's IP or MAC address are no longer sufficient. It's more important to grant access to resources based on user identity, location and the posture of the device accessing the WLAN. Wireless technologies are testing the physical boundaries, and any Enterprise relying on perimeter security can do so only at their own peril. A firewall at the perimeter was loaris trojan remover piratepc - Free Activators when you could ensure no malicious activity. Within wireless Enterprises, the corporate network sometimes extends beyond the corporate perimeter. The mobile workforce is no longer tied to their workplace, but can move and work from anywhere within the organization. Consequently, segregating network traffic using VLANs based on location is out of date.

The illustration above depicts how perimeter security is not enough to prevent wireless attacks. It is important to tackle Enterprise WLAN security from multiple dimensions and not rely on perimeter defences and wired Enterprise mentalities. In this guide, we identify some common security threats affect the WLAN. Well discuss the options and strategies available to mitigate each of these threats and the challenges in order to deploy a secure WLAN environment. This chapter is dedicated to the following Enterprise WLAN security concepts: Securing an Enterprise WLAN Network Integrity Checks Network Privacy Certifications and Legal Requirements WiFi Security Standards Overview

Securing the Wireless Enterprise 5-3

5.1 Securing an Enterprise WLAN


There are multiple dimensions to be considered when addressing the security of an Enterprise WLAN. One has to evaluate each with the utmost care and make sure there are no weak links in the chain. It starts with ensuring only the right users access the right information, preventing information from falling into the wrong hands and removing threats to network integrity through continuous monitoring and control. For an overview of the WiFi security standards impacting your Motorola Enterprise WLAN deployment, refer to WiFi Security Standards Overview on page 5-23.

5.1.1 Access Control


Access control ensures the right user accesses the right information. It starts with authenticating the user to ensure they are who they claim to be. While authentication ensures a network entity as a valid user, its silent on the kind of access the entity is entitled to. For example, a sales executive may not be authorized to access HR records. Or an employee may be authorized to access the Internet only during certain times of the day. Once authenticated, it's important to determine the users access control policy based on the networked devices MAC address, authentication type, user identity and current location.

5.1.2 802.1x Authentication with WPA/WPA2


Validating the identity of a network entity is the starting point on which any security policy is based. It can be based on the network device, like the MAC address of the device. Or user identity based, like user-id and password combination. The challenge of password based authentication is to find a secure way of sharing the password amongst credible users and ensure it satisfies cryptographic requirements. Wired Equivalent Privacy (WEP), was part of the initial 802.11 standard in 1999. In the interim, the Wi-fi alliance developed WiFi Protected Access (WPA). WPA & WPA2 recommend port based authentication (IEEE 802.1x) using the Extensible Authentication Protocol (EAP). 802.1x provides many authentication protocols, some of which use digital certificates and are based on well known standards like SSL. Since 802.1x is widely used for Enterprise authentication on the

5-4 WLAN Design Guide

wired side, organizations are familiar with it and can make use of the same infrastructure. The following lists some of the authentication methods used within Motorolas wireless LAN security protocols.
Protocol WEP WPA WPA2 Encryption WEP TKIP AES Authentication Shared Key 802.1x (dynamic WEP) 802.1x (EAP, PEAP, TTLS) PSK 802.1x (EAP, PEAP, TTLS) PSK Integrity CRC MIC CBC-MAC

NOTE: If using WPA-PSK or WPA2-PSK, keep in mind weak passwords are prone to dictionary and brute force attacks. Its critical a password policy be in place which mandates passphrases that are truly random, at least 20 bytes long, include alphanumeric characters and special symbols and change frequently (every two weeks or so).

5.1.3 Access Control Lists (ACLs)


Traditionally, ACLs only supported MAC address based authentication. But increasing WLAN sophistication saw various enhancements in ACLs. ACLs now have enhanced packet filtering capabilities, which can be at layer 3 (IP address, port number, protocol) or at layer 2 (MAC address, ether type, VLAN id). Thus, access can be granted based on packets matching the defined criteria.

5.1.4 VLAN Segregation


Virtual LANs (VLANs) have long been used in wired deployments to create logical workgroups and apply access and traffic management policies. The same benefit can be extended to wireless LANs. In the wired world, VLANs were defined based on .NET Reflector 10.1.11 Crack Full Version Download With Serial Number port (physical location) to which the user is connected. A VLAN should be configured based on the identity of the user in the wireless world, irrespective of t location. Access policies are then applied based on the VLAN the user belongs to. For Freemake Video Converter 4.1.12.81 Crack With Serial key Free, separate VLANs can be

created for employees and guest users. Guest users can then be prevented from accessing any other network resource apart from the Internet.

5.1.4.1 User Based VLANs


Traditionally, VLANs were assigned based on the WLAN. Users from a finance department would use WLAN-FINANCE, which in turn would map to VLAN 100. HR employees would access the wireless network WLAN-HR mapped to VLAN 200. With user based VLANs, all the employees in the organization would use the same WLAN, yet be mapped to different VLANs based on their identity. Lumion 9 crack - Free Activators is used in conjunction with 802.1x authentication, such that VLAN information is provided to the controller by the Radius server once the user is authenticated. The access policies are then applied to the employees specific to the VLAN they are mapped to.

5.1.5 Role Based Access Control


Wired clients access the network through a fixed port and location, usually protected by a physical boundary. This is not true for wireless networks. There is a need to find the identity of a wireless user and apply access policies based on their role within the organization, irrespective of the location from where they are accessing the wireless network. Even though Finance and Human Resource employees access the wireless network from a common cafeteria using a common ESSID, their access policies depend on their identities. Defining access policies for each user may be inconvenient and unnecessary. Users can be grouped according to their role, and access policies can be applied to the group based on their role. The user role can be identified based on parameters like device MAC address, authentication type, encryption type or ESSID. The group can be identified during authentication, by querying the group from the authentication server.
