AirDefense and MetaGeek aim analysis tools at wider
Eager to catch the wave of 802.11n wireless network upgrades and rollouts
presumably on the way, wireless LAN tools vendors are tuning up their products
and platforms with an eye toward making high-end wireless planning technologies
such as spectrum analysis available to a wider range of customers.
To this end, AirDefense
recently added SA (spectrum analysis) capabilities to its AirDefense
Enterprise 7.3 solution, and MetaGeek significantly improved its low-cost,
laptop-based spectrum analyzer Chanalyzer.
SA helps administrators
find non-Wi-Fi sources of interference in the unlicensed 2.4GHz and 5GHz
Many non-Wi-Fi devices,
such as cordless phones and Bluetooth devices, operate in those frequencies,
often using different modulation schemes. Too many transmitters in the same
airspace can lead to interference, resulting in service interruptions or signal
degradation for the Wi-Fi network.

Spectrum analyzers provide
the insight into the physical layer of wireless networking needed to help
identify and eradicate those sources of interference.
my tests of the two wireless analysis tools, I was impressed to see the steps
that AirDefense and MetaGeek have taken to put their utilities within reach of
a wider array of organizations.
