Cisco Systems is offering a Wi-Fi tool that reduces the
interference from rival networks and other competing wireless
devices.
Cisco is teaming up with Cognio to address radio frequency (RF)
interference.
Yankee analyst Zeus Kerravala said, “RF management should be a
priority in any enterprise wireless Lan deployment. To fully
realise the potential of a wireless network, it is critical to have
an understanding of the RF environment and a means of managing RF
conflicts.”
Complementing Cisco's Wireless Control System (WCS), the
comapany will now offer Cognio's Spectrum Expert, a Wi-Fi spectrum
analysis and monitoring tool.
Working with WCS, Spectrum Expert gives IT managers in-depth
analysis and reporting of the airwaves, giving administrators an
insight into RF issues and conflicts, helping them to rectify
problems.
Additionally, enterprises can use the solution to strengthen
their WLan security by determining the impact of non-Wi-Fi
devices.
Bluetooth-enabled devices, for instance, can impact on the
performance of Wi-Fi networks as they often use the same frequency
band.
The Cisco/Cognio system can also be used to identify and isolate
rogue devices used for unauthorised network access and denial of
service attacks.
