Quick Answer
Dropped calls in an office usually mean the indoor signal is too weak for a stable call, or the network is congested at peak hours. Measure RSRP and SINR at the desk, in meeting rooms and in the lobby before changing hardware.
Why calls drop in an office
A call needs a stable serving cell and enough signal quality. Low RSRP, low SINR, a sudden handover between cells or congestion at peak hours can all cause a drop. The fix is different in each case: more gain will not solve a congested network, and a new antenna will not fix a handover problem caused by the macro network.
What to measure
- RSRP and SINR at the desk, meeting rooms, lift lobby and the worst corner.
- Whether the drop happens at a fixed location or while moving between areas.
- Peak-hour behavior and whether Wi-Fi calling is enabled.
- Outdoor level at the nearest facade or roof position.
What usually fixes it
If the outdoor signal is usable and the office is shielded, a passive DAS with service antennas over workstations and meeting rooms usually fixes the coverage side. If the outdoor signal is weak, start with a high-gain donor and a higher-power host. If the network is congested, the answer is capacity planning or an operator-led small cell, not more booster gain.

Frequently Asked Questions
Will a booster stop all dropped calls?
It fixes drops caused by weak indoor coverage. If the drop is caused by macro congestion, a handover boundary or an operator issue, the booster alone will not solve it; measure first and confirm the cause.
Do we need a DAS or a single booster?
A single booster can work for a small office or a pilot zone. A multi-room or multi-floor office normally needs a passive DAS with several service antennas and a splitter design.
Can Wi-Fi calling help?
Yes, as a temporary workaround where the handset and carrier support it. It does not replace coverage for staff devices, POS terminals or emergency calls that rely on the mobile network.
