mnc

Mobile Network Code

Property definition:

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

Network measurements (Optional). Maximum of 8 uarfcn times maximum of 32 psc.

type : array
maxItems : 256

 Item properties:

ta

Timing advance (Optional). Round-Trip distance presented in the units of 4*c/7.68e6 ~156 meters. That is, the scaling factor is 4 times the chip length at chip rate of 7.68 Mchips/s. Note that at chip rates 1.28 Mchips/s and 3.84 Mchips/s you need to scale according to chip length of 7.68 Mchips/s, that is, multiply by 6 or 2 if needed.
