The WLAN management tool company adds radio features, site planning: I've spoken to a number of IT managers, largely but not exclusively in academia, who turned to AirWave as a way to better manage often hetergeneous wireless LANs that are comprised of equipment from many vendors. Some prefer AirWave to vendors' own management tools, too.
The latest version of their software includes site planning with visualization overlays--which boiled down means they can show RF patterns on a drawing. The planning tool doesn't offer simulation of signal propagation, which are part of other vendor-specific tools.
This version also adds rogue access point detection using the wired LAN as a primary tool to ferret out commodity APs without requiring constant network scanning. (This assumes undisguised APs, of course.) The company has extended the makers and brands of access points and switches they support, as well.
This new version ships this month.
