<p>The present invention relates to the field of communications, especially discloses a host communication module and slave communication module for efficient fast access close range wireless communication with a controllable communication range, wherein the host communication module is used for sending a first range reference signal including information of the host communication module and communication range information; and the slave communication module judges, according to the received first range reference signal, whether the communication range satisfies a preset scope, and if yes, the slave communication module establishes a fast wireless communication connection according to a preset protocol and performs data exchange. The first range reference signal can take the form of a low frequency magnetic signal or an ultrasonic signal in order to satisfy the requirement of close range access. The host communication module and slave communication module of the present invention provide a basic hardware carrier for realizing real-time, fast and efficient wireless data exchange within a specific range scope.</p> |
