Abstract: The present invention provides a virtual wireless network (VWN) system capable of integrating disparate wireless networks. The system includes a plurality of data stores containing information about Users, devices, services, policies and network configuration. This information is used by a VWN Processing Engine to establish and operate the network and to optimise the services provided across the VWN.

Abstract: A bridge device (4) for connecting a plurality of communication networks (1-3) around which data is transmitted in frames which include control information defining at least the identity of a destination for data in the frame, each network having at least one end station (8-12). The bridge device comprises a corresponding plurality of data coupling units (13,14) for connection to respective ones of the networks (1-3), each data coupling unit including receive (13) and transmit (14) interfaces for respectively receiving data from and transmitting data onto the connected network. A common store (17) is connected to all the data coupling units for receiving data being transmitted from one network to another.
