Mobile radio propagation tests at 920 MHz were carried out in urban areas. A signal transmitted from a base station was received by a dipole antenna installed near an aluminum case, which simulated the housing of a 20012560 mm3 portable set. Field strength deterioration due to body effect and penetration loss into buildings were measured.

Mobile radio propagation tests in the UHF band were carried out in urban areas. Signals transmitted from radio base stations were received by dipole antennas installed on an automobile and a small cart. Median values of field strength on streets and sidewalks were then measured. In addition, floor height gain characteristics of field strength were measured for a building in the downtown area.
