An antenna control algorithm is disclosed. Using this algorithm, the repeater will select an optimum antenna configuration at start-up. Once the configuration is selected, the system will keep this configuration until the performance metrics for this configuration drops below a specified level. At this point, the system will scan all antenna configurations to determine a new optimum configuration. In an alternative implementation, the repeater will select an optimum antenna configuration at start-up. Once the configuration is selected, the system will keep this configuration until the performance metrics for this configuration drops below a specified level. At this point, the system will start scanning antenna configurations to find a new configuration that yields a performance better than the required minimum performance level. This configuration would typically be faster than an optimum configuration as not all possible options need to be tested.
