Multihop network is an approach utilizing distributed wireless stations for relaying. In this system, area size, coverage and total transmit power efficiency can be improved. It is shown by computer simulations that the cooperative relaying scheme provides transmit diversity effect, and can offer much better performance compared with that of non-cooperation case. To confirm this superior performance in actual environments, field trials using real time communication equipments are now being planned. This paper reports the design and the performance of wireless equipments for field trials.
