Signal Strength vs Signal Quality
Most “wireless problems” aren’t a lack of signal — they’re a lack of usable signal. Strong strength can still be bad experience if quality is poor.
Strength is the received power level. On Wi-Fi you’ll hear RSSI. On cellular you’ll see metrics like RSRP. Strength helps indicate coverage, but it does not tell you whether the connection is clean.
Quality reflects how much of the received signal is “real” versus noise and interference. Metrics like SINR/SNR correlate strongly with throughput, call stability, and latency.
If quality is poor, adding “more signal” can make things worse (you amplify noise too). The fix may be channel planning, reducing interference, relocating equipment, or correcting power/placement — not just adding hardware.
We measure both coverage and quality, then recommend the smallest change that produces the biggest improvement (and we can validate results after changes are made).
