Connecting multiple buildings on a campus or facility with traditional wired copper or fibre networking can be challenging and expensive. Running underground fibre optic cables between buildings is not only costly but can also require significant construction and disruption. A great wireless alternative is using Ubiquiti’s UniFi devices in point-to-point (PTP) mode to bridge connections. In this post we’ll explain how to set up a PTP wireless link between two buildings using UniFi hardware.
Equipment Needed:
- Two UniFi devices with external antennas. Good options are the Building-to-Building Bridge or nanoStation Loco. Browse our Unifi P2P range View Range
- Direction adjustable antennas for both devices. Antennas with higher gain provide longer range.
- Grounded outdoor enclosures to house the devices. Surge protection is recommended.
- UniFi Controller software to configure and manage the link.
- Ethernet cabling to connect devices to inside networks.
Configuration Steps:
- Mount the External Antennas
- Choose suitable locations on rooftops or exterior walls with line of sight between buildings.
- Securely mount the external antennas, aiming them directly at each other.
- Install the UniFi Devices
- Connect the antennas and run ethernet cable into the buildings.
- Power on the devices and adopt them into the UniFi Controller.
- Align the Wireless Link
- Use the signal strength data in the Controller to optimize alignment. Small adjustments can make a big difference.
- Lock down the antenna mounts once aligned. Consider using cable ties as a safety.
- Configure the Wireless and Security Settings
- Set the PTP link password, frequency band, channel width, and other wireless settings.
- Enable wireless encryption like WPA2 for security over the bridge.
- Test Connectivity
- Verify full speeds and uninterrupted connectivity between the two networks with iPerf tests and pings.
- Monitor the link in the UniFi Controller and watch for any packet loss or drops.

With the wireless bridge in place, the two building networks are now connected securely. UniFi PTP links can span hundreds of feet to over a mile with the right antennas and line of sight.
