In short
A point-to-point link connects two locations with a pair of directional antennas that see each other, creating a network connection as if there were a cable. It joins warehouses, huts, pools, buildings on the same estate or distant cameras. A multipoint link connects several points to a central one. It needs line of sight and a firm installation.
Typical uses
- Taking internet from the main house to a guest house, garage or pool.
- Joining two warehouses, or a warehouse and a guard hut.
- Connecting cameras on the perimeter of an estate or car park.
- Sharing a fibre or Starlink connection between several buildings on one plot.
Requirements
- Clear line of sight between the two antennas, with no trees, buildings or terrain in between.
- Clearance around the line of sight, not just a gap: obstacles near the beam also matter.
- Firm, well-aimed mounts, protected against wind and lightning.
- Power at both ends, usually PoE from a switch or injector.
Point-to-point or multipoint
| Type | When to use it |
|---|---|
| Point-to-point | Joining two locations with maximum capacity and stability. |
| Point-to-multipoint | Taking the network from a central point to several buildings or cameras. |
| Mesh | Large outdoor areas where devices relay the signal between them. |
Installation and testing
Before installing we check line of sight and distance, and choose equipment for the throughput needed. After mounting we align the antennas using measured signal, set up encryption and monitor the link so we get an alert if it degrades.
