AbstractThe 2.5GHz band was assigned to mobile operators and local service operators for Wireless Broadband Systems in

the last of 2007. Then, broadband wireless network based on Mobile WiMAX was constructed in Azumino City. Two base- stations are installed in two years. Moreover, the local specific services and/or rest and secure network services, like internet access, live-camera system services, community radio system based on ICT and life recording system services, are developed on the network, and the field trial tests for these services have been carried out. The issue of the services should be extracted and improved.

Moreover, antenna beam-forming and MIMO with singular value decomposition technologies are studied in the field test, and OFDM MODEM with excellent frame synchronization and fast tracking equalization scheme are studied. Then, the route discovery method for sensor network is also studied.
