Problems solved by technology

[0003] In the prior art, in order to pass the SAR test, the maximum output power of the wireless communication module is usually limited to below the SAR test standard value
However, the problem with this is that the power is too low during normal use, resulting in reduced performance and poor throughput experience
And, generally speaking, the manufacturer of the signal transceiver chip contained in the wireless communication module does not support the dynamic change of power

Abstract

The invention discloses a wireless communication module and an electronic device. The wireless communication module comprises an antenna radiator, used for receiving data from the outside and sending data to the outside in a wireless mode; a signal transceiver chip, used for processing the data received by the antenna radiator from the outside or generating the data sent by the antenna radiator to the outside; a sensor, used for sensing the approaching of a human body within a preset threshold range of the antenna radiator and generating a sensing signal for indicating whether there is an approaching human body in the preset threshold range; and an attenuator, which is connected between the antenna radiator and the signal transceiver chip and is used for selectively attenuating the power of the signal transceiver chip based on the sensing signal of the sensor.

Description

technical field [0001] The present invention relates to the field of wireless communication, more specifically, to a wireless communication module and electronic equipment installed with the wireless communication module. Background technique [0002] In consideration of human health, the power of the wireless communication module cannot be too large. Therefore, the currently existing SAR test is to avoid affecting the health of the body due to electromagnetic radiation when the distance between the human body and the wireless communication module is very close. The full name of SAR in English is Specific Absorption Rate, and it is generally called electromagnetic wave absorption ratio or specific absorption rate in Chinese. It is the electromagnetic wave energy absorption ratio of mobile phones or wireless products. Since various organs of the human body are lossy media, the electromagnetic field in the body will generate currents, resulting in the absorption and dissipati...
