Abstract
Data distribution between mobile stations and external data paths is assigned to a new set of devices, distribution points. Each distribution point is independently coupled to mobile stations, also assigned to access points. Control elements operate to control the distribution points separately from the access points. Each access point maintains a substantially stateless link with each distribution point for which the two share a mobile station. Access points might exchange data with any one or more distribution points concurrently. Access points thus obtain greater bandwidth connectivity to external data paths. Mobile stations transfer between access points and transfer between distribution points independently. This has the effect that bandwidth connectivity between distribution points and external data paths have no particular requirement for VLAN separation. Mobile stations may roam among multiple Internet protocol subnets.
