Embodiment Construction

[0056] The general idea of ​​the present invention is: by calculating the received radio frequency signal, the distance parameter between two communication devices is obtained, thereby obtaining the actual distance between the two, and further determining whether the distance satisfies the distance condition for allowing communication, thereby Selectively communicate.

[0057] In order to make the technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0058] Please refer to figure 1, a communication device 10 is provided in this application, which includes: a receiving module, a parameter calculation module and a judging module. Wherein, the receiving module is used to receive the radio frequency signal transmitted by the second communication device; the parameter calculation module is used to calculate the distance parame...

Abstract

The invention discloses a communication device, system and method. The communication device judges whether or not to communicate with a second communication device, expected to communicate with the former communication device, by acquiring a distance between the communication device and the second communication device; the communication device can screen communication devices in a limited range, selective communication is achieved for the communication devices, and the communication mode is more diversified. In addition, a radio frequency channel different from an existing communication channel can be re-built and is used to send communication data; further, frequency of the radio frequency channel is set to be higher than that of the communication channel receiving radio frequency signals, a high-speed data transmission channel is newly built, and communication data can be transmitted at high speed on the high-speed data transmission channel; transmission speed of the communication device is increased, and communication experience is better.

Description

technical field [0001] The present invention relates to a communication device, system and method, in particular to a communication device, system and method capable of judging whether to communicate by acquiring a distance parameter between two communication devices. Background technique [0002] With the continuous development of my country's economy and the continuous improvement of people's living standards, the use of various data communication technologies in daily life is becoming more and more common, but most of the existing communication technologies use the method of identifying the other party's identity or communication address Judging whether to communicate with it, but when a communication device only wants to communicate with a communication device within a limited distance around it, the communication method in the prior art cannot accurately determine and screen the device for communication with it. Therefore, it is an urgent problem to be solved to enable t...
