The feasibility of an RF link can be estimated based on:
•
Distances between potential sites
•
Line of sight for RF paths
•
Antenna RF gains
•
Cable and connector losses
2.
Survey all obstructions to potential sites
Wherever possible, use an omnidirectional antenna. This ensures
maximum connectivity and allows the system to forward "packets" of
information for existing and future needs.
If the router requires a single link to another router, use a directional
antenna.

3.
Select the antenna type to be used
The wireless router is supplied with an omnidirectional antenna, but on
rare occasions a directional antenna may need to be used, depending on
area and topography.
