とれないので、移動局送信部の出力も大きくする必要が
あり消費電流が増大する。Next, the operation will be explained. The mobile station device 9 is in standby mode and is receiving a signal from the nearest base station 4. When calling the mobile station device 9 from the fixed base station 4, the base station 4
sends a paging signal to the mobile station device 9, and the mobile station device 9
sends a response signal in response to this and begins a call. When calling from the mobile station device 9 side, the mobile station device 9 transmits a request signal to the base station 4 and starts a call. In either case, since the transmitting/receiving antenna 3 of the nine mobile station devices is non-directional, it receives and transmits radio waves from unnecessary directions. Furthermore, since the transmitting/receiving antenna 3 cannot have a sufficient gain, the output of the mobile station transmitting section must also be increased, which increases current consumption.
