A point-to-point wireless link uses a pair of directional radios, one on each building, to carry a network connection between them. It needs line of sight and careful alignment, and delivers stable speeds over short to long distances depending on equipment. It is used to link buildings, remote gates, parking areas and distant CCTV cameras.
Key takeaways
- Two radios create a wireless cable between buildings.
- Line of sight is the key requirement.
- Range and speed depend on the equipment.
- Mounting and alignment decide stability.
- Plan lightning and surge protection.
01Where it works
| Use | Why it fits |
|---|---|
| Link two buildings | No trenching or digging |
| Remote gate or guardhouse | Bring cameras and access control onto the network |
| Parking or perimeter cameras | Carry video to the main building |
| Temporary sites | Quick to set up and move |
| Backup path | Second route if cable is damaged |
02Planning checklist
- Confirm line of sight between the points.
- Measure the distance.
- Plan mounting poles and power.
- Add surge and earthing protection.
- Test speed and stability after alignment.
