Title:
METHOD AND DEVICE FOR AUTOMATICALLY CALIBRATING WIRELESS FREQUENCY OFFSETS
Document Type and Number:
WIPO Patent Application WO/2019/024946
Kind Code:
A1
Abstract:
Discloses is a method for automatically calibrating wireless frequency offsets, comprising: a wireless fidelity (Wi-Fi) wireless transmission module monitors or scans for a specific data packet of access points (AP); the Wi-Fi wireless transmission module obtains, according to the specific data packet, the frequency offsets between the center frequency of the Wi-Fi wireless transmission module and the center frequencies of the APs; the Wi-Fi wireless transmission module performs frequency offset tracking according to the frequency offsets so as to control the Wi-Fi wireless transmission module to calculate a center frequency according to the frequency offsets obtained on the basis of the APs surrounding the Wi-Fi wireless transmission module, so that the frequency offsets between the center frequency calculated and the surrounding APs are all within a set standard, and the center frequency of the Wi-Fi wireless transmission module is adjusted according to the center frequency calculated. Also disclosed is a device for automatically calibrating wireless frequency offsets.
