mcc

Mobile Country Code

Property definition:

type : integer [min: 200, max: 999]
mnc

Mobile Network Code

Property definition:

type : integer [min: 0, max: 999]
nmr

LTE Network measurements (Optional)

type : array
maxItems : 16

 Item properties:

[see] : cell_lte_nmr
rsrp

Reference Signal Received Power = RSRP (dBm) (Optional, you must specify a value for this item when you specify a value for rsrq). Power less than -140dBm should be mapped to -140. Power greater than -44dBm should be mapped to -44.

Property definition:

type : integer [min: -140, max: -44]
rsrq

Reference Signal Received Quality = RSRQ (dB) (Optional). Values less than -19.5dB should be mapped to -19.5, and values greater than -3dB should be mapped to -3dB.

Property definition:

type : number [min: -19.5, max: -3]
ta

Timing Advance (Optional). Expressed in the units of 16*Ts (16 Basic time units) = 16/(15000*2048) seconds ~ 156meters. For reference see TS 36.213 and 36.211.

Property definition:

type : integer [min: 0, max: 1282]
tac

Tracking Area Code (Optional)

Property definition:

type : integer [min: 0, max: 65535]
