Brief Answer
In underground garages and parking garages, reinforced concrete, basements, ramps, and long driveways can significantly attenuate POLYCOM signals. Depending on the object and requirements, POLYCOM object coverage may be mandatory. Business radio for parking services or security must be separated and does not replace operational communication.
Parking facilities are important operational areas in case of events. Therefore, radio coverage should not only be noticeable during operation.
Why Parking Facilities are Critical
- Reinforced concrete and soil provide strong attenuation.
- Ramps and levels create dead spots.
- Emergency exits, sluices, and technical rooms must be considered.
- Vehicles and gates alter the radio environment.
What to Plan
| Topic | Importance |
|---|---|
| Clarification Obligation | Clarify with the relevant authorities. |
| Measurement | Check coverage per level. |
| Technology | Plan antennas, radiator cables, or amplifiers. |
| Business Radio | Consider separately for operator communication. |
Typical Mistakes
The parking facility is only regarded as a business radio problem. For response organizations, POLYCOM object coverage may also be required.
FAQ
Is POLYCOM mandatory in underground garages?
Depending on the object, canton, and requirements, it can be mandatory. This must be clarified specifically for the object.
Is a stronger radio device sufficient?
No. In-house coverage usually requires antenna, cable, or repeater technology.
Is parking radio the same as POLYCOM?
No. Business radio for parking services and POLYCOM for response organizations are different levels.
When to measure?
Early in planning and again at acceptance after implementation.
