Abstract :
Propagation characteristics of frequencies less than 2 GHz and of the microwave band have been studied by many authors. In these cases, vehicle-mount antennas were used for reception and the characteristics of break points were discussed. However, considering the remarkable growth of handy phone services, handy mode is more practical. This paper discusses the line of sight (LOS) path loss characteristics on break points by comparing handy mode and vehicle-mount mode of mobile stations. Disappearance of break point in handy mode is clarified through experimental results.
