5-Floor Office: Fixing Meeting-Room Dropouts Without Overloading the Network
A 2,400 m² office had usable signal at the windows but dropped calls in meeting rooms and the core. A three-band host with eight antennas balanced the floors.

The constraint was the site, not the hardware
- Window-side RSRP was acceptable, but meeting rooms and the building core fell to −98 to −101 dBm.
- The client wanted stable voice and data for video calls without changing the interior design.
- The basement car park was much weaker at −110 dBm and could not be fixed by the same antenna layout.
- The system had to avoid excessive uplink noise and keep the operator network protected.

Representative test points: before and after
Representative test points with rounded values. Actual results vary with floor, walls, antenna position and operator load.
| Test point | Before RSRP | After RSRP | Before SINR | After SINR |
|---|---|---|---|---|
| Roof donor reference | −78 dBm | −78 dBm | 7 dB | 7 dB |
| Meeting room, floor 3 | −101 dBm | −85 dBm | 1 dB | 15 dB |
| Open office, floor 4 | −98 dBm | −83 dBm | 2 dB | 17 dB |
| Core corridor | −104 dBm | −89 dBm | 0 dB | 10 dB |
| Basement car parkCoverage improved but remained below the office-floor target | −110 dBm | −91 dBm | −2 dB | 6 dB |
What changed
- Office floors measured −83 to −89 dBm, with SINR of 10–17 dB.
- Video calls and voice calls were stable in the tested meeting rooms and open offices.
- The basement improved to about −91 dBm but remained a candidate for a dedicated antenna design.
Engineering takeaways
- Window-side measurements can hide core and meeting-room problems. Test where people actually work.
- A three-band host can cover the primary carriers, but the extra band should be confirmed before ordering.
- Do not stretch an indoor design to cover a basement car park. Separate loss, antenna layout and sometimes a separate host are required.

Will the system interfere with the mobile network?
A properly installed system with adequate isolation, ALC/AGC and compliant output power should not interfere. Installation must follow local regulations and operator requirements.
Can the basement be added later?
Yes, but it should be designed as a separate zone with its own antenna calculation. Adding basement antennas to the same host may reduce the gain available to the office floors.
How long does a typical office installation take?
A project of this size is typically a multi-day installation, depending on cable routes, ceiling access and building permissions. The exact schedule is confirmed after a site visit.
