Short answer
Building radio is planned by considering requirements, radio services, critical areas, measurement points, antenna locations, repeaters, cable routes, power supply, fire protection, and maintenance together. Important is a radio measurement in the actual building or planning based on reliable construction and usage data. Good planning prevents radio dead zones, disturbances, unnecessary costs, and later modifications.
Building radio is not a single device, but a system of requirements, distribution, measurement, and operation.
Planning steps
- Define user groups and radio services.
- Define critical areas: basements, technical rooms, staircases, underground garages.
- Prepare inventory measurement or simulation.
- Plan antennas, repeaters, feeder cables, and cable routes.
- Define acceptance, documentation, maintenance, and change processes.
Particularly critical areas
| Area | Why critical? |
|---|---|
| Underground garage | Concrete, soil, and fire compartments significantly dampen signals. |
| Staircase | Important for safety and evacuation. |
| Technical rooms | Often shielded but operationally important. |
| Elevators | Movement and metal influence coverage. |
| New buildings | Insulation, glass, and metal can unexpectedly influence radio signals. |
Typical errors
Building radio is often planned too late. Then cable routes, power, fire protection approvals, or clean measurement points are missing. Early planning is almost always more economical.
FAQ
When should building radio be planned?
As early as possible, ideally before the construction completion or before major renovations.
Does every building need building radio?
No. Decisive factors include usage, construction type, safety requirements, and measured coverage.
What is the difference between a repeater and building radio?
A repeater amplifies or transmits radio signals. Building radio describes the entire supply concept within the building.
How is building radio accepted?
Through measurement, documentation, and verification against defined requirements.
