Method and storage medium for adjusting working frequency of electronic device, and electronic device

摘要

A method for adjusting a working frequency of an electronic device includes the following. First, determining a current working frequency of the electronic device, a minimum average frequency among the average frequencies of different channels, and a frequency range of one channel used for transmitting/receiving wireless signals. Second, calculating an interference frequency generated by the electronic device, and selecting another antenna to transmit/receive wireless signals when the interference frequency falls within the frequency range of the determined channel. Third, calculating a first time interval between transmitting and receiving wireless signals before switching to the other antenna, and a second time interval between transmitting and receiving wireless signals after switching to the other antenna. Fourth, determining a difference between the first and second time intervals. Fifth, adjusting the current working frequency to decrease the influence on the transmission/receipt of wireless signals when the calculated difference is greater than a predetermined threshold.
