摘要： A method of channel allocation for respective radios is disclosed. The method begins by scanning within sectors of a phased array for retrieval of BSSIDs belonging to each beam of a particular channel in the sectors. Then, corresponding characterizing information is recorded for every BSSID located. Next, an initial channel allocation for the respective radios is formed. The initial channel allocation is compared with a plurality of predetermined channel allocation modes that include a first mode of Point-to-Point (PtP) linkage, a second mode of MultiPoint-to-Point (MPtP) linkage, a third mode of Point-to-MultiPoint (PtMP) linkage, and a fourth mode of MultiPoint-To-MultiPoint (MPtMP) linkage, and a mode out of the predetermined channel allocation modes is selected that best characterizes the initial channel allocation. The radios are configured based on the channel allocation and unbalanced loading is reduced by adding/subtracting a non-overlapped frequency channel of a radio to an unbalanced beam.
