Short Answer
Mobile reception in the office is not reliably improved with individual tips but through a structured investigation. First, providers, rooms, signal quality, data performance, and telephony are measured. Afterwards, WiFi Calling, provider change, antenna/DAS solutions, operator-compliant repeaters, or Small Cells can be examined. For companies, it's important to clearly separate in-house mobile coverage from business radio, WLAN, and POLYCOM.
In offices, mobile issues often only become apparent when customer calls drop, mobile data is slow, or meeting rooms have little to no reception.
Meaningful Procedure in the Office
- Identify affected rooms, providers, and devices.
- Test voice, data, and reachability separately.
- Measure RSRP, RSRQ, SINR, and conduct speed tests.
- Check WLAN and WiFi Calling.
- Create operator inquiry and in-house concept.
Possible Solutions
| Solution | Suitable for |
|---|---|
| WiFi Calling | Individual offices with good WLAN. |
| Provider Check | If a provider is significantly weaker. |
| DAS | Larger buildings and multiple floors. |
| LTE/5G Repeaters | Only if planned operator-compliant. |
| Small Cells | Depending on the provider and project. |
Not to be Confused with Business Radio
Mobile reception concerns smartphones and public mobile networks. Business radio serves internal groups with radios. POLYCOM pertains to deploying organizations. In an office building, all three subjects can be relevant, but they address different problems.
FAQ
How can mobile reception in the office be improved?
Through measurement, provider inquiry, WiFi Calling, and if necessary, a professional in-house coverage.
Is WLAN Calling sufficient?
Often yes for telephony, but not always for mobile data, guest access, redundancy, or larger buildings.
Is an LTE repeater useful in the office?
Only if it is properly planned and approved by the provider.
When should a company seek measurement?
When multiple rooms, several users, or critical business processes are affected.
