Patent ID: 8767582

Claim:
An antenna array control method, comprising: selecting at least a packet as at least a probing packet every probing period; using one of the radiation patterns to be probed in an antenna array to transmit the probing packet; calculating packet error rates of the radiation patterns to be probed in the antenna array; and selecting the radiation pattern with a minimum packet error rate among all of the radiation patterns as a best radiation pattern; wherein when probing packet transmitting numbers of the radiation patterns to be probed are not equal to a probing packet transmitting window value, the radiation pattern with the minimum probing packet transmitting number is used to transmit the probing packet, wherein when the probing packet transmitting numbers of the radiation patterns to be probed are equal to the probing packet transmitting window value, the probing packet transmitting numbers of the radiation patterns to be probed are attenuated, the probing packet is transmitted by using the radiation pattern with a minimum packet error rate, and then the best radiation pattern is set to be the radiation pattern with the minimum packet error rate, and wherein a received signal strength indicator of each packet transmitted by using the best radiation pattern is calculated, a received signal strength indicator variation of the best radiation pattern is obtained according to the received signal strength indicators, and then the probing period, a statistic attenuation value, and a probing range of the radiation patterns to be probed are determined according to the received signal strength indicator variation.
