A cell site can be configured to have a first group of antennas arranged to provide coverage around the cell site and a second group of interleaved antennas that are interleaved between the antennas of the first group. The two groups can communicate at different frequency sets so that the two groups do not interfere with one another. Service nulls of one group that would otherwise be created by interference and low RSSI between antennas from the same group can be covered by the main beam of the other group, which can significantly improve SINR.
