Abstract: A transceiver that reduces power consumption when data is transferred between devices in different modes. The transceiver is arranged in a first node (6) and in a second node (9), which communicate between each other. A first control unit (12) generates a first signal transmitted from the first node in predetermined time intervals during a first period that establishes an environment for communication between the first node and the second node. The second node transmits a second signal transmitted in response to the first signal. The first control unit generates a third signal upon detection of the second signal. A second control unit (13) gradually decreases amplitude of the first signal based on the third signal to set the amplitude of the first signal to a predetermined amplitude so that the second node is receivable of the first signal.

Abstract translation: 一种收发器，可在不同模式的设备之间传输数据时降低功耗。 收发器布置在彼此通信的第一节点（6）和第二节点（9）中。 第一控制单元（12）在建立用于第一节点和第二节点之间的通信的环境的第一周期期间以预定时间间隔生成从第一节点发送的第一信号。 第二节点发送响应于第一信号而发送的第二信号。 第一控制单元在检测到第二信号时产生第三信号。 第二控制单元（13）基于第三信号逐渐降低第一信号的幅度，以将第一信号的幅度设置为预定幅度，使得第二节点可接收第一信号。
