All you have to do is initialize the Bridge radios (connect them to your router for a few minutes), connect one (the Bridge Gateway) to your network (your router, a Receiver, a Remote Hub, or even the Remote end of another Bridge) and mount it so it's aiming at the building you want to bring onto the network. Then mount the second radio (the Bridge Remote) on top of or on the side of your building, facing the AyrMesh Bridge Gateway radio, and plug a device into the “LAN” port on the AyrMesh Bridge Remote's power supply. That device will now be part of your network. You can also connect an Ethernet Switch to the LAN port of the Bridge Remote’s power supply and plug multiple Ethernet cables into it, to place several devices on the network. Finally, you can connect an AyrMesh IndoorHub to the Bridge radio to provide indoor WiFi.
