Cell Tower Location and Signal Testing

Record the serving cell, band, RSRP, RSRQ, SINR, latency and throughput while aiming the antenna at each candidate direction. Repeat tests at similar times and allow the modem to settle after each change. The nearest tower may be blocked, congested or not carry the required carrier bands, while a more distant tower may provide a cleaner path. Where the router supports band or cell information, use it to confirm that a direction change actually selected a …

Signal bars compress a complex radio condition into a simple graphic and may be based mainly on received power. They do not show interference, noise, cell congestion, band, tower selection or whether the connection is using a useful MIMO path. Two sites can show the same number of bars but have very different stability and throughput. Use numerical readings such as RSRP, RSRQ and SINR, note the serving band and cell, and run repeatable latency, upload and…

RSRP measures the power of the reference signal and helps indicate coverage strength. RSRQ combines signal and interference effects to describe quality, while SINR compares the wanted signal with interference and noise. Together they provide a much better picture than bars alone. A strong RSRP with poor SINR can indicate interference or congestion, so a higher-gain antenna may not fix the problem. A weaker but cleaner signal may deliver better performance…
