ELS61-US - not able to see 4G band 4 (1700/2100Mhz) | Thales IoT Developer Community

November 15, 2018 - 4:40pm, 4901 views

We've found that the modem fails to scan (or camp on) cell towers in 4G Band 4.

We have a Telit LE910-NA1 that is able to camp on these cells without problem.

The Telit modem describes the tower as:

AT&T RSRP:-94 RSRQ:-9 TAC:5411 Id:29D7C17 EARFCN:2150 PWR:-61dBm DRX:0

ATI1 returns:

Cinterion   ELS61-US  REVISION 01.000  A-REVISION 00.014.00  OK

I notice there is a new version of f/w available for this modem, released in August. I can't find the release notes for this though - could you make them available, please.

Thanks
