Understanding Antenna Gain:

Antenna gain refers to the ability of an antenna to focus or direct radio frequency (RF) energy in a specific direction. Higher gain antennas provide stronger signals and extended coverage in the direction they are focused.

Impact on AP Selection:

In scenarios where long-range coverage or better signal strength is required, an AP with a higher antenna gain (within regulatory limits) is preferred.

However, it is important to ensure that the antenna gain complies with the regulatory requirements of the country where it is deployed.

Conclusion:The statement is TRUE because higher antenna gain improves signal strength and coverage, making such APs desirable for specific use cases.
