AccessPoint-to-Client Ratio• One AccessPoint provides ethernet quality support to

multiple users • Roaming:

– Allows a station to move one AccessPoint to another within the same wireless network

– Eliminates conflicts and data loops

• Multi-Channel Roaming:– Makes it possible to support 3 non-overlapping channels within

the wireless network– Stations dynamically change channels when roaming from one

AccessPoint to another in the same wireless network – Cabletron supports Inter-AccessPoint Protocol (IAPP)
