Abstract:
1. A method, comprising: sending a plurality of signals to incrementally change a configuration of a group of antennas including a plurality of antennas of a wireless network, the plurality of signals including a first signal, a second signal and a third signal, the second signal being sent after the first signal and before the third signal; monitoring a performance metric value of the wireless network in response to each signal from the plurality of signals; defining a critical zone of the wireless network based on the performance metric value associated with the first signal, the performance metric value associated with the second signal and an operational condition associated with the performance metric, the critical zone including at least a first antenna from the plurality of antennas; and selecting, from the plurality of antennas, a set of neighbor antennas associated with the first antenna, the sending of the third signal including selecting a configuration of the first antenna for the third signal if the first antenna has available resources for achieving a predefined improvement in the performance metric of the wireless network, the sending of the third signal including selecting a configuration of a second antenna from the plurality of antennas for the third signal if the first antenna does not have adequate available resources for achieving the predefined improvement and if the second antenna has available resources for achieving the predefined improvement, the second antenna being from the set of neighbor antennas.
