A higher antenna gain indicates stronger signals and wider coverage.

A higher antenna gain indicates a narrower beamwidth and greater signal directivity—not necessarily wider coverage. While high-gain antennas can transmit stronger signals in a specific direction, they reduce coverage in other directions. In WLAN design, especially for omnidirectional coverage in campus scenarios, antenna selection is based on application requirements rather than simply preferring higher gain.

Huawei emphasizes that antenna gain must comply with local regulations and should match deployment scenarios (e.g., indoor omnidirectional vs outdoor long-range). Excessively high gain may result in coverage holes or regulatory non-compliance.
