Claim:
1. An autonomous radio controlling method, comprising: switching a plurality of antenna combinations in an antenna array; processing a plurality of signal-to-interference ratios (SIRs) and a plurality of received signal strength indicator (RSSI) values of the antenna combinations through a first computing process respectively to generate a plurality of first computed SIRs and a plurality of first computed RSSI values; processing the SIRs through a second computing process to generate a plurality of second computed SIRs; determining a relation between a minimum of the second computed SIRs and a first threshold value; further determining a relation between a minimum of the first computed SIRs and a first range if the minimum of the second computed SIRs is lower than the first threshold value; controlling an autonomous radio system to operate in a first mode if the minimum of the first computed SIRs is higher than the first range; controlling an autonomous radio system to operate in a second mode if the minimum of the first computed SIRs is lower than the first range; further determining a relation between a minimum of the first computed RSSI values and a second range if the minimum of the second computed SIRs is higher than the first threshold value; and controlling the autonomous radio system to operate in the first mode if the minimum of the first computed RSSI values is higher than the second range; controlling the autonomous radio system to operate in the second mode if the minimum of the first computed RSSI values is lower than the second range.
