Cisco Spectrum Expert f/ WiFi Cardbus networking card

Spectrum Expert f/ WiFi Cardbus 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.
