1.6.11 Antenna Placement

Antenna Placement

The performance of a wireless network greatly depends on signal strength of the wireless access point (AP) and the location of the wireless clients. Antenna placement can be crucial in allowing signals from the AP to reach the clients. This signal can be affected by the construction materials of walls, the network range, and the strength, sensitivity and quality of the antennas.

Signal strength depends on the environment in which the access point is placed. As a general rule, the greater the distance the signal travels, the more it will attenuate. Factors such as construction materials of walls, the network range, and the strength, sensitivity and quality of the antennas can further affect the signal strength.
In general, the AP should be at the center of a circle (or sphere) with a minimum radius.

Clients situated near the edge of the network range will likely experience network performance issues or dropped connections.

Avoid placing AP near objects that can absorb or reflect the signal.
