Point-to-point wireless links between buildings
By Vicky Ogola, Senior ICT Consultant 1 min read
Where trenching fibre is impractical, wireless bridges can link buildings — with clear line of sight and good planning.
Linking two buildings with fibre may require trenching across roads or permission from neighbours. A point-to-point wireless link can provide a fast connection in days rather than weeks.
Line of sight
The two antennas must see each other clearly. Trees, buildings and even the ground can block the signal — and the area around the direct line must also be reasonably clear.
Choose the right equipment
Distance, required capacity and local interference determine the radio, antenna and frequency band. Licensed bands reduce interference but involve regulatory processes.
Mount securely
Rigid mounts keep antennas aligned in wind. Even small movements can degrade a long link.
Protect against weather and surges
Use weatherproof connectors, proper earthing and surge protection on cables entering buildings.
Secure the link
Encrypt traffic and change default credentials on radios.
Monitor
Track signal levels and throughput so degradation — from growing trees or interference — is noticed early.
Consider a backup
For critical links, a second path keeps buildings connected.
