For the purpose of creating a mobile multimedia society, the part of broadband communication in next generation mobile communication systems should be supported by wireless LAN technologies. Especially for public service applications, wireless LAN requires several features, i.e., to have as high mobility as cellular systems have and a high data rate which cannot be obtained with cellular systems. The authors confirmed those capabilities using the 5 GHz/25 GHz OFDM wireless LAN systems HiSWANa/ARIB STD-T70 and HiSWANb/ARIB STD-T83. As for a high-speed mobile system, Japan Railway's express train "Shikoku Ishizuchi" was chosen and transmission at 95 km/hour up to a distance of 800 meters was achieved. As for the high data uplink requirement, the emergency medical system was recommended and a 10 Mbps wireless uplink was achieved when transmitting cardiograph information and video signals from, respectively, the ultrasonic diagnostic equipment and video cameras viewing the patient and the scene of the accident.
