New CiscoWorks Wireless LAN Solution Engine Release 2.5 Detects Rogue Access Points and Radio Frequency Interference
Cisco Systems® is pleased to announce the availability of a new release of the CiscoWorks Wireless LAN Solution Engine (WLSE)—a core component of the Cisco® Structured Wireless-Aware Network (SWAN). This new release of the CiscoWorks WLSE takes full advantage of the radio frequency (RF) measurement capabilities built into Cisco Aironet® access points to detect, locate, and mitigate RF interference and unauthorized (rogue) access points. CiscoWorks WLSE Release 2.5 also provides a new assisted site survey tool to facilitate automated deployment and ongoing operation and management of Cisco Aironet access points.
The CiscoWorks WLSE is a centralized, systems-level solution for managing the entire Cisco Aironet wireless LAN (WLAN) infrastructure. The advanced air/RF and device management features of the CiscoWorks WLSE simplify everyday operation of WLANs, ensure smooth deployment, enhance security, and maximize network availability, while reducing deployment and operating expenses.
Cisco SWAN is a secure, integrated WLAN solution of Cisco "wireless-aware" infrastructure products that minimize WLAN total cost of ownership through optimized deployment and management of market-proven high-performance multifunction Cisco Aironet access points. This cost-effective Cisco solution ensures that WLANs have the same level of security, scalability, reliability, ease of deployment, and management as wired LANs. With Cisco SWAN, hundreds to thousands of central or remotely located Cisco Aironet access points can be managed from a single management console- CiscoWorks WLSE.
CiscoWorks WLSE Release 2.5 enhancements include:
•Air/RF scanning and monitoring—Cisco Aironet access points are multifunctional, with built-in RF measurement capabilities. The CiscoWorks WLSE analyzes air/RF measurements, provides notification if performance degrades, and displays the air/RF coverage area. Any Wi-Fi certified client device may be used in the WLAN. However, using Cisco Aironet WLAN client adapters and Cisco Compatible client devices provides extended radio management data because these adapters can send their RF readings to CiscoWorks WLSE. Cisco and Cisco Compatible client air scanning and monitoring provides 10 to 20 times more RF measurement data than access point RF measurements alone because as WLAN clients move about all areas of a building, they scan and monitor a broad coverage area allowing for more accurate rogue-access-point detection.
•Interference detection—The CiscoWorks WLSE catalogues the physical location of all managed access points and creates a site map of the WLAN installation. This allows the wireless-aware network to detect points of interfering RF energy that are affecting network performance. The source of this RF energy could be a rogue access point or a device that operates in the same frequency range, such as a 2.4-GHz cordless telephone or leaky microwave oven.
•Wireless intrusion detection—The CiscoWorks WLSE enables administrators to quickly and easily detect, locate, and disable rogue access points. Details are displayed about the switch port into which the rogue access point is connected, and the physical location of the rogue access point is shown on the Location Manager GUI.
•Assisted site surveys—The CiscoWorks WLSE automates the previously manual, expensive, and time-consuming process of determining optimal access point radio transmit power and channel selection. The CiscoWorks WLSE analyzes RF measurements from Cisco Aironet access points, Cisco Aironet WLAN client adapters, and Cisco Compatible client devices, and then determines the optimal channel selection, transmit power, and other access point settings, which may be applied by the administrator.
•Location Manager—The Location Manager is a GUI that displays wireless access points and bridges on a building floor plan. The location of rogue access points and RF interference is represented visually on the floor plan, as is the coverage area of each access point.
Customers interested in purchasing the new CiscoWorks WLSE Release 2.5 may place orders immediately through their normal sales channels. A CiscoWorks WLSE Release 2.5 upgrade is available for download by customers who have an earlier CiscoWorks WLSE version. CiscoWorks WLSE software contains encryption technologies controlled by the U.S. government, and users who want to download software will be prompted to apply for permission to access the encrypted files.
Table 1 lists the ordering information for CiscoWorks WLSE.
Important: CiscoWorks WLSE includes strong encryption technology that is restricted for some types of U.S. export.

Questions and Answers
Q. What IEEE 802.11 technologies do CiscoWorks WLSE 2.5 radio management and network management features support?
A. CiscoWorks WLSE 2.5 radio management features support IEEE 802.11b Cisco Aironet access points, Cisco client adapters, and Cisco Compatible client devices today. Radio management support for Cisco Aironet 802.11a and 802.11g radios is planned for the second quarter of calendar year 2004. CiscoWorks WLSE network management capabilities are available for 802.11a and 802.11b Cisco Aironet access points, Cisco client adapters, and Cisco Compatible client devices today, with support for 802.11g planned for the second quarter of calendar year 2004.
Q. Can older versions of CiscoWorks WLSE hardware run CiscoWorks WLSE Software 2.X?
A. Yes, but the number of access points and bridges supported is limited to 500. Customers who want to scale beyond that number will need to upgrade hardware to the CWWLSE-1130-K9 hardware platform.
