MOBILE RADIO TELEPHONE SYSTEM FOR EXPRESS HIGHWAYS

An 800 MHz automatic land mobile radiotelephone system with a 100,000 subscriber capacity, in commercial use in the Tokyo metropolitan area, will be expanded to other large cities. With the increase in service areas, it will be necessary to provide mobile radiotelephone service along Japan's inter-city express highways. Estimation of call traffic on express highways is shown. Service area and radio zone configuration concepts which satisfy the express highway requirements are proposed. Small-capacity base station radio equipment, a common amplifier with less distortion, and antenna coupling loss are discussed. Highway radio propagation properties in flat and mountainous areas are examined.
