The Fresnel zone defines the area surrounding a line-of-sight link that must be free of obstructions that might cause out-of-phase reflections that can significantly degrade signal quality. The image to the right is an example of a potential client with an obstruction that is within the Fresnel zone of the link. In this case, a signal reflection coy will arrive at the receiver and degrade the signal quality.

The repeater station uses the same Ubiquiti PowerBeam PBE-5AC-500 to communicate with the antenna in Picton. Width a small beam width of 6 degrees we don't flood the whole of Picton with our WiFi signal. For Boons valley an Ubiquiti NanoBeam NBE-5AC-19 is used. This particular antenna has the same theoretical throughput of 450Mbps, operates on 5.8GHz but has a beam width of 60 degrees. By using a wide angle antenna on top of the hill only one antenna is required to connect multiple clients. Also known as a point to multipoint (PTMP). A 5-port switch provides three spare connections for future add-ons.
The repeater station uses the following equipment:
