What is the antenna gain of AP1?

• A. 6 dBi
• B. 8 dBi
• C. 10 dBi
• D. 12 dBi

Answer: (B)

Antenna gain is how much the antenna concentrates energy in its strongest direction compared with an ideal isotropic radiator, and it’s measured in dBi. Higher gain means stronger signal in the main direction and typically a longer reach in that direction, at the expense of coverage spreading in other directions.

For AP1, the specified antenna gain is eight dBi. This value indicates the main signal direction is boosted enough to extend coverage and improve signal strength where users are most likely to be, while still offering broad enough coverage for typical campus layouts. It’s a balance point: higher gains can narrow the beam and create gaps, while lower gains don’t reach as far. Eight dBi is a common, practical choice for many indoor/outdoor deployments, providing solid range without severely limiting coverage in other areas.
