A university lecture hall has high client density. Which antenna type is most appropriate to reduce co-channel interference and improve coverage?

High-gain directional antennas are designed for long-distance or narrow-beam links and would create very small, uneven coverage footprints unsuitable for broad indoor seating areas.

Omni-directional antennas radiate equally in all directions, causing excessive signal overlap between adjacent APs and increasing co-channel interference in dense deployments.

Patch and panel antennas radiate in a defined forward hemisphere, allowing network designers to shape coverage toward seated audience areas while minimizing signal bleed into neighboring cells. This controlled pattern reduces co-channel interference between nearby APs, which is the primary challenge in high-density environments. They strike the right balance between coverage area and interference mitigation for indoor dense deployments.

Yagi antennas are highly directional with a very narrow beamwidth, making them suited for outdoor point-to-point bridging rather than broad indoor coverage.
