Site Survey Utilities • RF protocol analyzer examples – Sniffer Technologies Wireless Sniffer Pro – AiroPeek WildPackets RF Packet Sniffers – AirMagnet • Hardware spectrum analyzers AirMagnet on PDA – Agilent (HP Products) Spectrum Analyzers © 2006 Cisco Systems, Inc All rights reserved CWLF v1.0—m7-5 There are several vendors that offer tools to manage the RF spectrum, and Cisco has several partners for such tools A few of them are listed in the figure, in no particular order, to provide an example of other RF tools available Site survey software is a basic tool Most vendors supply a site survey application as a Windows application that runs on the user laptop A wireless client card hears the signal from the access point and measures the signal strength and signal quality The features of these applications vary, but they all have the common function of signal strength and signal quality display Using this software helps you determine cell size and available data rates at various distances from the access point and helps you determine optimal access point placement The Cisco Site Survey screen gives bar graphs for signal strength, noise level, signal-to-noise ratio and link speed on the access point to which the client is associated It also provides information about all access points which it can hear RF packet sniffers provide the following functions: 7-122 „ Identify network problems efficiently „ Spot security risks in real time „ Troubleshoot problems „ Analyze RF traffic Cisco Wireless LAN Fundamentals (CWLF) v1.0 Copyright © 2006, Cisco Systems, Inc Problems with your WLAN installation can be caused by unplanned changes in the environment (such as moved walls or added file cabinets), growth in the number of network users, security breaches (hackers or rogue access points), or improper configuration parameters An RF sniffer has features that can help solve problems as well as prevent them The features include the following: „ „ „ Monitoring and capturing packets — The analyzer passively monitors and captures all data traffic sent over the wireless LAN within radio range of the analyzer and stores the data in a file on the laptop hard drive — The passive operation of the analyzer avoids adding any performance impact on the network Decoding — The analyzer interrogates the received data and decodes its protocol type and frame structure — It decodes 802.11 control, management, and data frames — It provides information on SSID, access point channels, and data rates for all users — Analyzers can decode WEP-encrypted data — Most analyzers also decode higher-layer protocols, such as TCP/IP, AppleTalk, and NetBEUI Filtering — Analyzers filter received data, perform statistical analysis on the data, and display the results according to user preferences — They can be used for monitoring and troubleshooting the network For example, analyzers can display the SSIDs of all access points and users and help spot whether a user is attempting to associate using an incorrect SSID Analyzers can also display the actual throughput of all users (by specific channel) and identify unauthorized users and access points that not fit an acceptable profile One sniffer application is AirMagnet, available for both PC and PDA, which can be used to conduct site surveys and perform troubleshooting diagnostics for most WLAN problems It offers a compact form factor and an affordable price point Hardware spectrum analyzers include products from Tektronix, Agilent, and Berkeley Varitronics Systems Spectrum analyzers visualize RF signals and graphically illustrate the amplitude of signals within a specific channel These products enable you to differentiate between 802.11b signals and other RF sources that may be causing interference They also enable you to locate and eliminate the source of interference Copyright © 2006, Cisco Systems, Inc WLAN Management Solutions 7-123 Tool Comparison This topic identifies tools available for various network management tasks and the advantages and disadvantages Pros and Cons of RF Tools Protocol analyzers • Monitor/capture/analyze 802.11 traffic • Resource requirements—expensive, time-intensive • Certain functionality specific to certain tools and not to others Client Card Site Survey Utilities • Often come with client card • Usually passive • Will not work with other clients Spectrum analyzers • Show all RF in the environment – not just 802.11 • Resource requirements—expensive, time-intensive © 2006 Cisco Systems, Inc All rights reserved CWLF v1.0—m7-6 The pros and cons of various RF tools include the following: 7-124 „ Protocol analyzers allow you to monitor, capture, and analyze 802.11 traffic Protocol Analyzers that provide full decodes and work with WLAN clients can be expensive, and time-intensive to use Certain functionalities are specific to certain tools and not to others „ Client Card Site Survey Utilities often come with the client card They are usually passive tools that only listen to the network These tools usually will not work with other clients „ Third-party site survey tools can work with multiple clients and usually provide active and passive tests They also often have tools that allow you to provide maps of the RF coverage These tools can be more expensive and still will only work with the clients specifed by the manufacturer „ Spectrum analyzers show all RF in the environment and present the information in a graphical format that shows the amplitude and wave form of any energy in the RF environment This tool is very useful for identifying non– 802.11 sources of interference These tools usually can analyze a large area of the RF spectrum and can be quite expensive and time-intensive
