Command To See Active Bands Available?
I have looked & found how to change what band the modem searches through, locking bands, & selecting multiple bands for Carrier Aggregation. However, I have not found any information on the results of the modems scanning the bands. I assume there is a command to show what the modem actually finds in its scan, the signal strength on each band found, etc. Can someone please provide some information on the subject. Sorry for the newbie question! Thx!

Re: Command To See Active Bands Available?
I'm not aware of a way to do this. Bands are specific to which carrier you are using (AT&T / Verizon / etc). The easiest way to tell, given the carrier you are using, is to leave the modem unlocked, and let it connect. At that point, you should see what primary cell, and if any, secondary cell you are connected to, and which bands those are.

You can either use a Samsung phone in test mode (by dialing *#0011# which works most but not all phones) with the router's sim inside to see the currently used band/channel/RSSI/etc, or send bands info AT commands on the router's terminal (or Putty). Most modem makes and models have their own set of commands, so you'll need to search for the proper ones.
Here are the currently used bands of all major US carriers.
Note, that not all bands are in use in all locations.
All other prepaid/reseller/MVNO carriers like Tracfone, Boost, etc use the main carrier's bands/towers, and in some locations only partially. "*" means primary bands:
ATT - *2, 4, 5, 12, 14, 17, 29, 30, 46, 66
TMO - 2, *4, 5, 12, 46, 66, 71
VZW - 2, 4, 5, 12, *13
SPR - *25, 26, 41
