Using general- purpose platforms and software modules instead of application specific hardware can facili-tate application of the software radio technique using computer and network based architecture. As the developmentof network, a new technology of software radio based on network-Visual Radio is proposed. In this paper, wederivate the concept of Visual Radio which is based on network from Software Defined Radio's developing process; in-troduce its background and narrate its technical content and peculiarity,and expect its future.
In this paper ,we give a overview of a new broadband wireless access technology, introduce the theory ofLMDS and its constitutes ;at the same time ,we analyzed the advantages and disadvantages of LMDS and its future.
