The research on wireless ATM architecture

Each wireless technology now used is optimized just for some particular applications and environments. However, the next generation wireless networks coexisting with fiber-optic based broadband communication networks will be required to operate over a wide range of cell size (from picocell to massive satellite cell) and offer multimedia services where each service may have a unique rate. A new architecture of wireless network, wireless ATM, is proposed in this paper, which consolidates various radio environments and applications under a single protocol. The wireless ATM architecture embedded into B-ISDN protocol stack can adapt a wide range of physical channels. In the last section, flow control, the key technique of multiplex and multiple access in wireless ATM, is described.
