Remote Mining Camp: Why a Booster Was the Wrong Answer
Outdoor tests at three candidate donor points returned −105 to −110 dBm. With no usable macro signal, a booster would amplify noise, not coverage.

Negative diagnosis example
The constraint was the site, not the hardware
- The camp had no usable outdoor signal. Staff relied on walking to a ridge or using satellite phones.
- The client initially asked for a booster because the problem looked like an indoor coverage issue.
- A booster cannot create signal where the donor level is below the operating threshold.
- The site needed a connectivity solution that could support voice, data and possibly CCTV.

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 |
|---|---|---|---|---|
| North ridge candidateBest reading after antenna height and direction sweep | −108 dBm | N/A | 0 dB | N/A |
| Water tower candidate | −110 dBm | N/A | −1 dB | N/A |
| Camp roof candidate | −105 dBm | N/A | 0 dB | N/A |
What changed
- The client avoided buying equipment that could not work at the site.
- The project moved to a satellite backhaul and private connectivity evaluation.
- The negative diagnosis became a reference for future remote-site screening.
Engineering takeaways
- Measure outdoor RSRP before discussing a booster. If there is no usable donor signal, stop the booster path.
- A clear “no” protects the client from wasted equipment and protects the operator network.
- Remote sites need a connectivity assessment, not just an indoor coverage design.

Why can’t a booster fix this site?
A booster needs a usable donor signal from the macro network. At −105 to −110 dBm outdoors, the signal is below the practical operating threshold, so amplification would add noise and create instability.
What alternatives were recommended?
Satellite backhaul with local Wi-Fi was the first option. Private LTE or a point-to-point link was considered if a usable donor site could be found.
Can the site be re-tested later?
Yes. Coverage can change after new sites are deployed or seasonal foliage changes. A re-test should record the operator, band, height and antenna direction.
