Foundry has added some new features to its wireless LAN switch platform: It now supports Layer 3 roaming, which means that users can remain on their subnet even when they move into the range of a different subnet so that users can move throughout a building or campus without losing their session. Foundry's APs now support up to eight SSIDs so that network administrators can set up different profiles for different users, such as guests, contract workers, and employees. The APs can also now be set to act as dedicated probes that only monitor the air for rogue activity.
