Definition
A relay is a device used to bridge a signal gap in the WiFi network. Typical situations requiring a relay would be;
If an obstruction prevents line of sight between one device and the next (e.g. a hill, trees, building)
One or more device(s) is out of range of other devices in the mesh network (typically 1500 feet or more)
Note: If either, or both, of the above situations apply, relay(s) should be included in the installation plan.
In this example, a relay has been added to navigate signal around a treeline between the base unit and the valve locations.
Relay Position Assessment
Complete a site visit, or collect all valve location coordinates
Identify the device(s) that are not likely to connect to the mesh network due to the conditions above
Obstructions may be evaluated during the site visit or by using a mapping tool such as Google Earth
Long distances may be measured using a mapping tool such as Google Earth, or on-site using a laser distance meter
If an obstruction prevents line of sight:
Either in person or using a mapping tool, identify an area that has line of sight to both the device that requires a relay and the nearest device connected to the mesh network
Verify that this area is within 1500 feet of both devices
If devices are within line of sight but exceed the permissible range:
Either in person or using a mapping tool, identify an area that has line of sight to both the device that requires a relay and the nearest device connected to the mesh network. The relay location should be equidistant between the two devices if possible.
Verify that this area is within 1500 feet of both devices
Relay mounted on trellis to bridge signal between plant blocks on either side of the road
Relay Installation Parts
(1) 2” dome
(1) Standard solar panel and antenna assembly
(1) Relay mount assembly
(1) L-bracket
(2) Philips head screws (included)
(2) Self-drilling hex head screws
(2) Hose clamps or conduit claps
Relay Installation Process
Assemble a solar panel and antenna bracket
Fix L-bracket to pole using (2) self-drilling screws, positioned around the halfway point of the pole (if using 5 foot poles)
Power on the dome
Fix dome to relay mount assembly using the dome retaining nut and Lumo wrench
Place cap on dome
Fix relay mount (with dome) to L-bracket using (2) philips head screws
Tie down solar and antenna cables, and connect cables to dome
Vertically mount pole to a post or other infrastructure using hose clamps or conduit clamps (for wood surfaces)
In the Ops Center, check connectivity of the device, ensuring RSSI for the relay and connected device(s) is greater than -80 (between 0 and -80)
Move the relay position or adjust the height of the antenna to improve RSSI as needed
