  • Patent number: 7633908
    Abstract: A mobile ad hoc network is formed by selecting at least one client to function as a Virtual Mobile Server (“VMS”) on behalf of other clients: Those other clients subsequently communicate with a cell station via the VMS on an UWB format. Other clients may function as Virtual Distributed Mobile Servers (“VDMSs”) which relay communications between the VMS and clients which are out of direct communication range of the VMS. Further, multiple VMSs may be implemented for a single ad hoc network in order to bundle bandwidth. Clients may also extend the communication range of the VMS to a new cell station in order to enable earlier initiation of cell station handoff.
