cell​_​tdscdma​_​locate

TD-SCDMA measurement

type: object

[Required properties: mcc, mnc, 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 Location Area Code (Optional)
cid integer x ≥ 0 | x ≤ 268435455 required UTRAN Cell Identifier, 28 bits (12 bits RNC and 16 bits Cell id). Mcc+mnc+cid uniquely identifies the TDSCDMA cell, lac is optional.
ta integer x ≥ 0 | x ≤ 1530 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.
nmr cell_​tdscdma_​nmr Network measurements (Optional). Maximum of 8 uarfcn times maximum of 32 psc.
