"Can WiFi really go that far?"

Yes — with the right equipment. Regular WiFi routers use omnidirectional antennas that spread signal in all directions. Point-to-point links use directional antennas that focus all their energy in a narrow beam, allowing connections over kilometers.

Products like Ubiquiti's airMAX or LiteBeam are designed exactly for this. They operate on unlicensed frequencies (5 GHz) and can link buildings 2 km apart or more with a clear line of sight.

The key requirements:

  • Line of sight — the antennas must "see" each other. Trees, buildings, and hills are your enemies.
  • Proper alignment — a few degrees off and you lose the connection
  • Height — mounting antennas on rooftops or poles makes a huge difference

Work in Progress

This section will cover how point-to-point links work, how to plan them, and what equipment to use.
