WiFi Point-to-Point Bridge: How to Connect Two Buildings Wirelessly

Do you want to connect your office building with the production hall, or bring your home WiFi to a garden house 100 meters away without digging trenches for cables? The solution is a Point-to-Point WiFi link (Wireless Bridge).

Thanks to modern technology, distances from a few meters to over 30 kilometers can be bridged—achieving data throughputs that easily rival a physical fiber optic connection.

The Core Requirement: Line of Sight (LOS)

The most important rule for a stable wireless bridge is: Clear Line of Sight (LOS). WiFi radio waves over long distances are extremely sensitive to obstacles.

• Short Distances (up to 100m): The signal might still penetrate a wooden wall or light foliage, albeit with a slight drop in bandwidth.
• Long Distances (250m and beyond): An absolutely clear line of sight is mandatory. Solid obstacles like concrete walls, dense trees, or hills make stable operation impossible. Additionally, the so-called Fresnel Zone (the invisible area around the direct radio beam) must be clear of obstructions.

Our Advice: Always mount the antennas outdoors, ideally on the roof or on an elevated mast.

Which Frequency Band is Right for You?

Choosing the right frequency determines your range and data throughput.

2.4 GHz – Only in Exceptions

The 2.4 GHz band is extremely congested today. Since almost every home WiFi and Bluetooth device operates on it, massive interference occurs in urban areas. We advise against building a 2.4 GHz bridge unless you are in a very rural area and need to penetrate a light obstacle (like a single tree).

5 GHz – The Stable Standard

The 5 GHz band is our standard recommendation. It offers significantly more non-overlapping channels, suffers less interference from neighboring networks, and delivers real data throughputs of up to 500 Mbps with modern ac/ax standards.

60 GHz – Gigabit Speed for Professionals

For extremely data-intensive applications (e.g., 4K camera surveillance or server synchronization), we recommend the 60 GHz band. This high frequency enables Gigabit data throughput with extremely low latency. The only catch: 60 GHz absolutely requires a flawless line of sight, as the waves can be attenuated even by heavy rain.

Hardware: Our CPE Recommendations

Forget tinkering with separate routers and antennas. Use CPEs (Customer Premises Equipment). These are weatherproof outdoor devices that optimally combine the WiFi module and the directional antenna. Power is conveniently supplied via the network cable using PoE (Power over Ethernet).

• Ubiquiti Networks (Best Value): Highly user-friendly and extremely stable. Using their proprietary airMAX protocol, high throughputs are easily achieved. Recommendation: NanoBeam 5AC Gen2 (short/medium range) or PowerBeam (long range).
• MikroTik: The favorite for network professionals seeking maximum configuration freedom, e.g., with the Wireless Wire Cube (60 GHz).

Configuration: It’s That Simple

The setup usually runs in a transparent bridge mode. This means the wireless link acts exactly like an invisible, long network cable.

1. Device A (Access Point Mode): Here you assign the SSID (the network name for the bridge) and a highly secure WPA2/WPA3 password.
2. Device B (Station / Client Mode): This device scans for the SSID of Device A. Enter the password, and the devices will connect.
3. Tuning: Make sure to activate the manufacturer's proprietary protocols (airMAX for Ubiquiti or iPoll for LigoWave) to massively increase data throughput compared to standard WiFi protocols.
