RFSTS and ABND

[Eric Tsai]

I’d like to collect more statistics around cellular connectivity health. When I run PSNT, I get feedback on whether I”m on LTE or 3G for the LAT3 (CAT-1 Dragonfly module). Specifically, I’d like to determine the active band (frequency) being used.

So, the 4 from PSNT tells me I’m on LTE.

AT#PSNT?
#PSNT: 0,4

Then I get this result from RFSTS:

AT#RFSTS
#RFSTS: “310 410″,2175,-108,-80,-9.5,4604,01,0,128,19,1,4EE7917,”310410890606729″,”AT&T”,3,4,720,3240

According to datasheet, the active band field (“ABND”) corresponds to “4EE7917”.

Am I looking at the correct field?

How do I convert “4EE7917” to some kind of LTE band or frequency?

Here’s a better breakdown of the fields label:
