  • Multimode wireless radio access network with distributed processing
    Patent number: 8045972
    Abstract: A multimode Radio Access Network (RAN) for wireless communication is disclosed. The RAN separates the control signals from the data streams for their distributed processing. The control signals are transmitted between base stations and a Radio Resource Server (RRS), while the data streams are communicated between the base stations and Wireless Access Gateways (WAGs). The base station and WAG resources are managed by the RRS. Besides providing single and multiple radio mode access to a mobile user for efficient communication with other wireless communication networks, the RAN infrastructure has a high outage tolerance and can be scaled cost effectively for wider coverage and increased data traffic capacity.
