Abstract
Provided is a method for automatically calibrating wireless frequency offsets. The method includes following steps: a wireless fidelity (Wi-Fi) wireless transmission module monitors or scans a specific data packet of an access point (AP); the Wi-Fi wireless transmission module acquires a frequency offset between a central frequency of the Wi-Fi wireless transmission module and a central frequency of the AP according to the specific data packet; the Wi-Fi wireless transmission module executes frequency offset tracking according to the frequency offset to control the Wi-Fi wireless transmission module to calculate a central frequency according to a frequency offset acquired for a surrounding AP of the Wi-Fi wireless transmission module in such a way that each of the calculated central frequency and the frequency offset for the surrounding AP is in a preset standard, and adjusts the central frequency of the Wi-Fi wireless transmission module according to the calculated central frequency. Provided is also a device for automatically calibrating wireless frequency offsets.
