Abstract
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.

An access point device, comprising:
- a processor;
- and
- a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations, comprising:
- determining spectrum data indicative of frequency ranges that the access point device utilizes for communication;
- determining first data indicative of a first portion of the frequency ranges of the spectrum data;
- determining second data indicative of a second portion of the frequency ranges of the spectrum data that does not overlap the first portion;
- facilitating first communication via transceivers that utilize the first portion of the frequency ranges, wherein a first transceiver of the transceivers has a first azimuth that differs from a second azimuth of a second transceiver of the transceivers, wherein the first azimuth is associated with a first sector served by the first transceiver, wherein the second azimuth is associated with a second sector served by the second transceiver, and wherein a sector boundary between the first sector and the second sector comprises a null region that has formed in response to interference between first signals at the first portion of the frequency ranges propagated by the first transceiver and second signals at the first portion of the frequency ranges propagated by the second transceiver;
- and
- facilitating second communication via interleaved transceivers that utilize the second portion of the frequency ranges, wherein a first interleaved transceiver of the interleaved transceivers has an interleaved azimuth between the first azimuth and the second azimuth that is selected to correspond to the null region.

A non-transitory machine-readable storage medium, comprising executable instructions that, when executed by a processor, facilitate performance of operations, comprising, comprising:
- determining first data representing a first portion of all frequency ranges an access point device uses to communicate over the air;
- determining second data representing a second portion of the frequency ranges, wherein the second portion is a remainder of frequencies not included in the first portion;
- facilitating first communication via antennas that utilize the first portion of the frequency ranges, wherein a first antenna of the antennas has a first azimuth that is not a second azimuth of a second antenna of the antennas;
- and
- facilitating second communication via interleaved antennas that utilize the second portion of the frequency ranges, wherein a first interleaved antenna of the interleaved antennas has an interleaved azimuth approximately midway between the first azimuth and the second azimuth that is selected to extend through a null region indicative of interference between the first antenna and the second antenna.

A method, comprising:
- determining, by a network device comprising a processor, first portion data representing a portion of all spectrum an access point device uses to communicate wirelessly;
- overlap
- determining, by the network device, second portion data indicative of a remaining portion of the spectrum that does not comprise the portion;
- facilitating, by the network device, first communication via transceivers that utilize the first portion data, wherein a first transceiver of the transceivers has a first azimuth that is different from a second azimuth of a second transceiver of the transceivers;
- and
- facilitating, by the network device, second communication via interleaved transceivers that utilize the second portion data, wherein a first interleaved transceiver of the interleaved transceivers has an interleaved azimuth substantially midway between the first azimuth and the second azimuth, and wherein the interleaved azimuth is determined to target a null region indicative of interference generated between the first transceiver and the second transceiver.
