Radio over fiber transmission technology for ITS and mobile communications

CRL (Communications Research Laboratory. Independent Administrative Institu tion Japan) is developing a road to vehicle multiple-service communication system based on RoF (Radio over Fiber) technology in a millimeter-wave freq uency region of 36-37 GHz. In the experimental system, vehicle can receive three wireless services such as PHS (Personal Handy-phone System). ETC (Ele ctronic Toll Collection system). SB (Satellite Broadcasting). In this paper , the system concept and experimental System Configuration are introduced. Furthermore, SDR (Software Defined Radio) mobile terminal technology is men tioned and a new concept for a next generation mobile communication network system based on RoF is proposed.
