The PHS system for wireless local calls adopts microcellular structure, with the frequency of 1.9GHz, the average transmitting power of mobile phones is 10 MW, and the average output power of base stations is 10 MW, which is even smaller than that of ordinary home TV remote controllers and children's remote control toy cars.
The frequency is different, the transmission power is small, and the factors that eliminate the quality and fault of the base station will not interfere in theory.
