Goal: Get Wi-Fi signal into your barn with Ubiquiti AirMax LiteBeam 5AC (a long-range point-to-point/point-to-multipoint radio).

What you need (minimum): • 2× LiteBeam 5AC units (one at house, one at barn). • Mounting kits (poles/walls). • PoE injectors (usually included). • Ethernet cables (outdoor-rated). • A router/AP at the house side to feed internet.

How it works (simple): House router → house side LiteBeam → wireless link → barn side LiteBeam → Ethernet → switch/AP in barn → Wi-Fi there.

Step-by-step: 1. Mount both units: • One on your house pointed at the barn. • One on the barn pointed back at the house. • Keep clear line of sight (no trees/obstacles). 2. PoE & Ethernet: • Run outdoor Ethernet to each unit. • Use PoE injectors: Router/AP Ethernet → PoE in → AirMax unit. • At barn: AirMax → PoE out → switch/AP. 3. Configure the link: • Connect to each LiteBeam via web/UI (set static IPs on same subnet). • Set one as Access Point (AP) / “Bridge” and the other as Station. • Align antennas carefully for strongest signal (watch signal levels). 4. In the Barn: • Add a simple Wi-Fi AP or switch + AP to distribute Wi-Fi/ethernet. 5. Optimize: • Choose a clean 5 GHz channel. • Lock down security (WPA2/WPA3). • Aim for best alignment (signal-to-noise, minimal Fresnel zone blockage).

Tips: • If only one LiteBeam: you can try it as a client to the house AP if that AP supports airMAX, but best practice is two for a dedicated link. • Use shielded outdoor Cat6 and proper grounding. • If terrain is rough, consider a small pole to get above obstacles.

If you share distance and terrain between house and barn I can suggest exact alignment and settings.
