How it works
A point-to-point wireless link uses two fixed endpoints to carry network traffic between locations. It can join buildings where a suitable cable route is unavailable. Directional equipment focuses the radio path, while the local networks at each end still need appropriate switching, addressing and Wi-Fi coverage for users.
Important differences and limits
A clear-looking view does not establish reliable capacity. Distance, the surrounding radio environment, the space around the direct path and antenna alignment matter. A link is not simply a stronger household Wi-Fi extender. Its advertised radio rate is not the same as real application throughput in both directions.
A useful practical check
Map the two endpoints and assess mounting, power and a genuinely clear radio path. Confirm compatible equipment and the intended network arrangement before installation. Test sustained transfers in both directions and watch for interruptions, not only a short speed result. Include cable protection and access for maintenance in the installation plan.
An example in practice
A link to a separate building can carry a network connection, but it does not automatically provide good Wi-Fi inside that building. A local access point may still be needed there. Test the link independently from room coverage so the two performance problems are not confused. Measure wired performance at the remote endpoint first, then measure Wi-Fi inside the building to identify which stage limits use.
