Virtual cellular network: a new wireless communications architecture with multiple access ports

A new cellular communication architecture, called a `virtual cellular network´ (VCN) is proposed and its performance is investigated in terms of probability of capture, throughput and delay. A VCN does not use a conventional cellular frequency reuse concept. In a VCN, each terminal sends packets using the entire system bandwidth while any nearby port can pick up the signal. Then, the ports relay the packets to the port server (PS) over a fixed (wired) network. This simplifies the functions of a port, and the placement of ports will be easier than that in a conventional cellular network. Both the present analysis and simulation show that despite its simplicity this network has a larger user capacity than conventional cellular reuse patterns
