METHOD FOR CONTROLLING SPECIFIC ABSORPTION RATIO OF WIRELESS COMMUNICATION DEVICE, AND WIRELESS COMMUNICATION DEVICE

Title:

METHOD FOR CONTROLLING SPECIFIC ABSORPTION RATIO OF WIRELESS COMMUNICATION DEVICE, AND WIRELESS COMMUNICATION DEVICE

Document Type and Number:

WIPO Patent Application WO/2018/010100

Kind Code:

A1

Abstract:

Provided in the present invention are a method for controlling the specific absorption ratio of a wireless communication device, and a wireless communication device, the wireless communication device comprising a first antenna and a second antenna. The method comprises the wireless communication device using the first antenna to deliver a radio frequency signal, and when the transmission power of the first antenna reaches a first preset power and a first time period finishes, stopping the use of the first antenna, and starting to use the second antenna to deliver the radio frequency signal, such that the wireless communication device meets the SAR standard. The process of controlling the specific absorption ratio of the wireless communication device does not roll back the transmission power of the antennae, and therefore, whilst meeting the SAR standard, the communication quality of the wireless communication device is also ensured.
