cell​_​gsm​_​locate

GSM measurement

type: object

[Required properties: mcc, mnc, lac, cid]

Properties

Name Type Required Description
mcc integer x ≥ 200 | x ≤ 999 required Mobile Country Code
mnc integer x ≥ 0 | x ≤ 999 required Mobile Network Code
lac integer x ≥ 1 | x ≤ 65535 required Location Area Code
cid integer x ≥ 0 | x ≤ 65535 required Cell Identifier, 16 bits. Mcc+mnc+lac+cid uniquely identifies the GSM cell.
ta integer x ≥ 0 | x ≤ 63 Timing advance (Optional). Expressed in the units of GSM bits equaling to 48/13 μs ~ 1107 meters.
rxlevel integer x ≥ -110 | x ≤ -25 Received Signal power (dBm) (Optional). Power less than -110dBm should be mapped to -110. Power greater than -25dBm should be mapped to -25.
nmr cell_​gsm_​nmr Network measurements (Optional)
