Cisco Spectrum Intelligence Solution Simplifies Detection,
Classification, Location, and Troubleshooting of RF
Interference
Classification, Location, and Troubleshooting of RF
Interference
Challenge
Radio frequency (RF) interference from devices operating in the unlicensed 2.4-GHz and 5-GHz
bands used by wireless LANs (WLANs) is a growing concern for organizations deploying indoor
and outdoor wireless networks. A variety of RF devices are now available that can cause
interference, including cordless phones, Bluetooth devices, cameras, paging systems,
unauthorized access points, and clients in ad-hoc mode.
Organizations need a fast and efficient method to detect, classify, and locate sources of potential
RF interference. Left unaddressed, RF interference can result in low data rates and throughput,
lack of sufficient WLAN coverage, WLAN performance degradation, poor voice quality, and low
end-user satisfaction. This, in turn, can lead to decreased network capacity, an increase in support
calls, network downtime, rising operational costs, and potential security vulnerabilities from
malicious interference.
Solution
The
Cisco
Unified Wireless Network
supports real-time spectrum intelligence for Wi-Fi networks.
This industry-leading solution detects, classifies, and locates devices causing RF interference in
the unlicensed 2.4-GHz and 5-GHz bands. For this solution, the
Cisco Wireless Control System
(WCS)
works in conjunction with
Cisco Spectrum Expert
Wi-Fi
to provide visibility into non-Wi-Fi
interference sources that may cause wireless performance degradation. When the source of the
interference is determined, customers can remove, move, shield, adjust, or replace the
interference source. This helps organizations troubleshoot the wireless network to determine the
root causes of interference problems and optimize network performance.
Cisco introduced RF spectrum intelligence capabilities with
Cisco Unified Wireless Network
Software Release 4.1
. Additional enhancements are delivered in
Cisco Unified Wireless Network
Software Release 4.2
. To implement the full Cisco Spectrum Intelligence solution, organizations
must be running Cisco WCS Software Release 4.2 or later and add a Cisco WCS Spectrum
Intelligence license (Cisco Product ID: WCS-ADV-SI-SE-10) and one or more Cisco Spectrum
Expert Wi-Fi 3.2 or later (Cisco Product ID: AIR-CSCO-SE-WIFI-C).
Organizations can improve coverage, capacity, quality of service, and security of wireless networks
when RF interference is quickly detected and mitigated. With the Cisco Spectrum Intelligence
solution, organizations can identify and resolve RF problems more efficiently, resulting in an
enhanced user experience and lowered operational costs.
Features
The Cisco Unified Wireless Network includes the following features to support identification,
classification, and location of devices causing RF interference in the unlicensed 2.4-GHz and 5-
GHz bands.
