Hello,

Legato version: 18.06  
Module: WP76xx

1. Legatos le\_mrc\_Rat\_t has these technologies available:  
enum [le\_mrc\_Rat\_t](https://docs.legato.io/14_04_1/le__mrc_8h.html#aaf23906c37ad59fb96a8a48f7fab5b43) {  
[LE\_MRC\_RAT\_UNKNOWN](https://docs.legato.io/14_04_1/le__mrc_8h.html#aaf23906c37ad59fb96a8a48f7fab5b43a6088198c65a39429fe6a67f322df0480) = 0, [LE\_MRC\_RAT\_GSM](https://docs.legato.io/14_04_1/le__mrc_8h.html#aaf23906c37ad59fb96a8a48f7fab5b43ae19505d98b78ac22398bce06605dd1a4) = 1\<\<0, [LE\_MRC\_RAT\_UMTS](https://docs.legato.io/14_04_1/le__mrc_8h.html#aaf23906c37ad59fb96a8a48f7fab5b43afe34c4f3a53aa717f5ecb94dd59bf728) = 1\<\<1, [LE\_MRC\_RAT\_LTE](https://docs.legato.io/14_04_1/le__mrc_8h.html#aaf23906c37ad59fb96a8a48f7fab5b43aaf2b25a8ec75f9bacb51967f23247176) = 1\<\<2,  
[LE\_MRC\_RAT\_CDMA](https://docs.legato.io/14_04_1/le__mrc_8h.html#aaf23906c37ad59fb96a8a48f7fab5b43a1634a4ab71f130dd2aae46aa09ca0771) = 1\<\<3, [LE\_MRC\_RAT\_ALL](https://docs.legato.io/14_04_1/le__mrc_8h.html#aaf23906c37ad59fb96a8a48f7fab5b43aac032f28348a900d439ce496e20c586a)  
}

Im using googles geolocation service in order to obtain location from it, and I need to connect each of these RAT’s with `lte` , `gsm` , `cdma` , and `wcdma` .  
Is this correct:  
**LE\_MRC\_RAT\_UMTS** = “wcdma”  
**LE\_MRC\_RAT\_TDSCDMA** = “cdma”  
LE\_MRC\_RAT\_LTE = “lte”  
LE\_MRC\_RAT\_CDMA = “cdma”  
LE\_MRC\_RAT\_GSM = “gsm”

I am unsured about the bold ones. Please help.

**LE\_MRC\_RAT\_TDSCDMA** should be TD-SCDMA according to cm\_mrc.c

@lazzox

UMTS is 3G as we know it in Europe and 3G on AT&T in the US, TDSCDMA was the Chinese version of 3G deployed mainly in China.
