Cisco unveils spectrum intelligence technology to combat RF interference

As unlicensed spectrum becomes clogged with a plethora of RF devices-including smartphones, Bluetooth devices, baby monitors, microwave ovens, wireless video cameras and cordless phones-enterprise IT specialists are having a difficult time creating reliable, mission-critical in-building WiFi networks because of the interference from the plethora of devices.

Hence, Cisco today introduced access points complete with AP intelligence to identify, classify, locate and mitigate around interfering signals. The new Aironet 3500 series of APs includes a technology Cisco called CleanAir technology that consists of a CleanAir application-specific integrated circuit (ASIC) in the access point with system-level intelligence to offer up detailed interference information.

"IT is struggling to make [WiFi] infrastructure mission-critical. Right now it's best effort," said Chris Kozup, senior manager, mobility solutions with Cisco, in an interview. "IT just doesn't have the expertise to make it mission critical...What CleanAir allows network administrators to [do is] put on a magnifying glass and understand what is happening to the RF signal."
