ABSTRACT:
An ATM radio transmission apparatus includes an ATM unit having a normal operation mode and a low power consumption mode, a CPU for determining a transmission request based on information of a radio section, and a control line for switching an operation mode of the ATM unit from the CPU. The operation mode of the ATM unit is switched between the normal operation mode and the low power consumption mode in accordance with the transmission request of the radio section. When the reception is requested from a base station, the ATM unit is operated, and when the transmission/reception with the base station is completed, the ATM unit is shifted to the low power consumption mode to reduce the power consumption.
