Zusammenfassung: | To provide a base station apparatus which can decrease the number of radio units used as required, and reduce electric power consumption.SOLUTION: A base station apparatus comprises: a plurality of radio units (21-25) which use frequencies different from each other; power source parts (12) provided for the radio units respectively; and a control part (20) which controls switching between a first mode (normal mode) for at least operating two or more first radio units (22, 23) operable to transmit audio data according to FDMA system, and a second mode (power restriction mode) for at least operating one second radio unit (24) operable to transmit audio data according to SCPC system. The control part (20) cuts off a power source to the first radio units (22, 23) in the second mode (power restriction mode).SELECTED DRAWING: Figure 1
【課題】必要に応じて使用する無線機の数を削減し、電力消費を抑制することが可能な基地局装置を提供する。【解決手段】互いに異なる周波数を使用する複数の無線機(21〜25)を備えると共に、無線機毎に電源部(12)が設けられた基地局装置において、FDMA方式で音声データを送信する2つ以上の第1無線機(22,23)を少なくとも動作させる第1モード(通常モード)と、SCPC方式で音声データを送信する1つの第2無線機(24)を少なくとも動作させる第2モード(電力制限モード)との切り替えを制御する制御部(20)を備え、制御部(20)は、第2モード(電力制限モード)では第1無線機(22,23)の電源を遮断する。【選択図】図1 |
