AirMagnet has an impressive portfolio of wireless LAN security and management products, and it has continued to be one of the leading companies in this space by expanding that portfolio. The latest addition - AirMagnet Spectrum Analyzer (ASA) - is a welcome addition because it fills the RF (Radio Frequency) analysis capability gap that AirMagnet has had.
RF analysis is important because packet-level products like AirMagnet's Enterprise, and Laptop and Handheld Analyzer products [reviewed here] rely on being able to receive and decode WLAN signals. But sometimes the problem in a wireless LAN is caused by RF interference sources that don't emit valid 802.11a/b/g signals. Microwave ovens, cordless phones and Bluetooth devices are the most prevalent sources of RF interference, although by no means the only ones.
