Point-to-point wireless links connect two locations without a physical cable between them. They can be useful for linking buildings, remote facilities or network sites, but reliability depends on the path between radios, interference, mounting, alignment and the required capacity.
Check the path before buying radios
A clear visual line of sight is a starting point, not a complete radio survey. The Fresnel zone around the path should also be considered because trees, buildings and terrain can obstruct part of the signal even when both antennas are visible. Check distance, elevation and likely obstructions before selecting equipment.
Match radio design to the traffic
Estimate the bandwidth needed during busy periods and decide whether the link will carry office data, cameras, voice or several services. Frequency band, channel width, antenna gain and local interference affect performance. A headline PHY rate should not be treated as guaranteed usable throughput.
Install and monitor carefully
Use suitable mounts, weather protection, grounding and cable routing. Align antennas accurately and verify signal quality, noise levels and real throughput after installation. Plan a fallback if the connection carries critical business traffic. Explore wireless and ISP equipment after the link requirements are documented.
