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)
