Abstract	A radio paging system using a 200 band NRZ-digital code for the selective calling signal on new frequency bands is discussed. This system uses the 250-MHz band, and its propagation characteristics in urban areas, necessary for the radio system design, was measured in the Tokyo area. Distance versus median field strength characteristics in this band approximate that of the 150-MHz band. Building loss is 19.7 dB and is less than that of the 150-MHz band. Therefore, the new system will provide nearly the same grade of service as the former system using the 150-MHz band.
