Abstract :
The wide area ubiquitous network (WAUN), which is used for transmitting and receiving information for sensors and actuators, is proposed and the feasibility study of a new wireless network for the WAUN is described. The WAUN is designed to satisfy the requirements of many new applications using sensors and actuators, which are wirelessly connected to the IP network. One of the basic requirements for the wireless system of the WAUN is wide coverage larger than several km with low wireless terminal output power of 10 mW To meet this requirement, an experimental wireless system, which uses a powerful FEC and the diversity technique, for use in WAUNs is designed, and its feasibility is evaluated by field experiments. The experimental results demonstrate the feasibility of the WAUN. That is, the 10 mW transmission power wireless terminal communicates with the access point (base station) 5 km away
