I believe what it does with CA depends on the supported combinations for the bands you have available.
Here we have B1 B3 B7 and B20 and no it will not do anything other than 2CA unless you restrict the band set. But I think that's just a not so mature firmware.

Anyway the EM20 performs better in both DL and UL (everything else being the same), at least here. Ran many tests in different times of the day.

I am running a EM160. I have been learning and experimenting, and greatly appreciate this site.

Is there a way to bump a band down in priority, but still keep it?

For example if 14 is giving me the strongest signal but 66 gives me higher speeds then to make it push to 66 but still keep 14. When 66 is priority and it aggregates with 14 I am getting 50Mbs down. 12 seemed like it was slowing me down so I excluded it altogether.

I used the command AT+QNWPREFCFG="lte_band",2:4:14:30:66 to set the bands I wanted to aggregate.

There is a command in there that allows you to define your top 3 bands you prefer. I've not seen how well it works though. I'd have to dig. Its under the QENG command set I think, but it may be under NWPREFCFG commands.

These newer modems are nice since they let you lock the bands using decimal numbers ("lte_band",X:Y:Z) instead of those crazy binary bit masks on previous models. While band-locking may help narrow down the operating bands, it can also prevent the modem from scanning and using newly enabled or changed band assignments by the carrier, which can happen at any time. Therefore I highly recommend running the modem in auto-scan mode, or at least setting it to auto-scan once in a while to prevent missing out on some new goodies. ;)

Ok so I understand now how to set the bands now thanks to this!! I'm wanting to set my own but how would I go back to default (using all available bands) without resetting everthing? sorry i'm new to this lol and can you choose which is the main band to use out of the 3 bands I'd like to use? I'm trying to exclude just band 66 really but then again as long as band 66 isn't the primary band its connected to then it's wonderful actually, just doesn't like being the "main" band.

Code: Select all

AT+QNWPREFCFG="lte_band",1:2:3:4:5:7:8:12:13:14:18:19:20:25:26:28:29:30:32:38:39:40:41:42:43:46:48:66

I like to exclude all non-US bands.

Ok... Nice read on the EM160, but I have one question:

1- I want to use 2 2x2 mimo antennas with this. What are the at commands to activate the secondary pair?

Check out this thread:
https://ltehacks.com/viewtopic.php?f=15&t=2294

I have tried to do the same thing but cannot get it to work. If I run:
AT+QCFG=?
then it shows
"lte4x4mimo/disable", (0,1)
as a valid command, but if I try to execute the command, it returns an error.

If anyone figures out how to make it work, please let me know.

Removed due to duplication.
