Experts answer: PHS call quality is not good, suddenly pass suddenly blocked, causing the main reason for this situation is determined by the characteristics of PHS technology. PHS advanced ADPCM decoding, supposedly close to the fixed phone call quality call quality. However, because of its based on PHS technology, transmission power is very small (compared CDMA transmit power is smaller, the benefits of environmental protection, energy saving), vulnerability is obvious. This makes the PHS would set up every 200 meters of a base station. In addition to the large number of base stations, network construction to bring difficult and also resulted in the movement (that is, when you walk or ride) state, PHS frequently switch Signal. If the switching speed can not catch the change of base rate will affect the call to signal instability. It also causes less penetration PHS signals. If you are indoors or in high-rise buildings near the signal is weak. You may to to the window, door or the terrace call to improve results.
