Abstract
A multi-band wireless access point includes a first antenna system including at least one antenna and having a first effective range for communicating with subscribers using a first communications protocol and a second antenna system including a plurality of antennas generally co-located with the first antenna system and having a second effective range for communicating with subscribers using a second communications protocol whereby the first and the second effective ranges are effectively coextensive. Moreover, each of the plurality of antennas in the second antenna system has a greater directivity than the at least one antenna in the first antenna system to compensate for a difference in propagation of the second communications protocol relative to the first communications protocol.
