RF glossary & units
A quick reference for fields used throughout the workspace.
Common units and identities
Retain source identities and units in reports and exports. Missing values are not evidence of zero signal. Device-reported SNR is not automatically interchangeable with every vendor SINR counter.
| Field | Meaning / unit |
|---|---|
| RSRP / SS-RSRP | LTE / NR reference-signal received power, dBm; do not silently mix the two. |
| RSRQ / SNR | Quality / signal-to-noise indicators, dB; inspect source measurement semantics. |
| DL / UL | Downlink / uplink. Throughput is Mbps, not MB/s. |
| PCI / Cell ID | Physical identity / serving-cell identifier. PCI alone is not globally unique. |
| dBm / dBi / dB | Absolute power / antenna gain / ratio or loss; these are not interchangeable. |
| MAPL | Maximum allowable path loss, dB, for stated directional assumptions. |
| A3 / TTT | Neighbor comparison / time-to-trigger. Timer inputs use milliseconds. |
| WGS84 / GPS | Latitude and longitude in degrees; GeoJSON coordinate arrays are longitude first. |
| ROP / PRB | Reporting observation period / physical resource blocks. Specify aggregation and percent conventions. |
Engineering evidence terms
Coverage gap: sustained weak-signal samples under the selected rule, not proven geographic absence of service. Ping-pong: a return transition candidate under a timing rule, not automatically a failed signaling procedure.
Calibration: fit model parameters against verified observations. Holdout: observations deliberately excluded from that fit. Residual: prediction minus measurement under the stated convention. Use independent spatial blocks and repeat drives to assess generalization.
