I downloaded an app called 'Advanced Signal Status' from the Play store. It says I'm on LTE 14. From my reading today, I was expecting to see either 13 (reguar LTE), or 4 (AWS/XLTE).
I live in PCB, and the rollout included P'Cola and Tallahassee. I'm not sure if I'm under either of those umbrellas, so I wanted to check. Since I don't know what the 14 meains, I'm not sure what I've got. But you could give it a try.
Note that to access the part of this app that will provide this info, you have to be rooted.
Hope this helps.
Yes. You have to be on mj7 modem or above to have access to band 4 aws or xlte as Verizon has rebranded it.

I am on CM11 5/18 nightly and just flashed the latest modem I545VRUNC5. I am in one of the markets for XLTE and wasn't sure if I had to do anything to my phone in order to get the XLTE. But found that once I flashed the latest modem and later in the day, found that speeds were faster without changing any settings. Prior to flashing NC5, I was on MJ7 but wasn't getting the speed. Guess it could have just been the time of day and the rollout was still on it's way, but no matter now.. very happy with it!!!!

Make sure you grab the one that says it's the modem only
I'm currently rooted on MK2, stock ROM and everything, and have no desire to go any further than just upgrading the modem, can I install only the necessary modem over MK2 or do I need to do a complete upgrade of the ROM and/or firmware?
EDIT: I just read the last page in that modems thread and people are saying MK2 should be able to take advantage of AWS, however I'm still getting the same speeds I've always been getting. What gives? I'm in Rochester NY and others in my area have confirmed they are now seeing AWS service levels.

You have the MK2 Modem, which is already above MJ7, so no need to worry about that.

XLTE vs LTE on the Galaxy S4
I have just performed 2 out of 3 video tests I plan to do with my Galaxy S4 to address this very issue. All are on the same device. Video #1 is LTE test and, just a few minutes after, Video #2 is testing XLTE.
I have yet to find a "Application" that shows properly Band 4 or Band 13 so we can tell, but the Service Menu DOES TELL! You just have to unlock it. Also, I had previously thought that XLTE was using both bands to double it's bandwidth. This of course is NOT the case. The device switches over entirely from one band to the other. The Service Menu shows that Band 4 mode is utilizing 20Mhz as apposed the original 10Mhz on LTE Band 13. Double the Mhz bandwidth, that explains it!
