AT&T LTE and Network Discussion

Well no phones run N30 yet, and there is no N46 to my knowledge. 3G is going to be sunset and it'll be completed by what 2022 iirc. Could always just turn that off on sites early. Doubt it though. Most likely will use DSS though

To be clear, I'm betting they'll run n5 dedicated, plus maybe n2/66, as well as additional LTE on 30 and maybe 46.

I seriously doubt they'll drop H+ in these areas until their deadline. Far too many phones can't do VoLTE on AT&T.

Per some requests, we're going to try out an AT&T discussion thread along the same lines as the T-Mobile discussion thread.  We're going to see how it goes. Enjoy! - Trip

I'm starting to see my 5G mapping show up on CellMapper. I'm still surprised by how little N5 is active in Louisville, especially considering how many sites should be capable based on B5 LTE added dur

I found something interesting while looking through some AT&T site plans I found online, this is from a site in Connecticut. Looks like they have a SiriusXM repeater on the B30 antenna. I'm guessi

Quick look, looks like it was a 20mhz connection on N2, that's not too bad. Wonder if it's DSS or all n2 being converted from LTE. Also noticed B1w being the Primary carrier with N2, that's interesting. From what I've seen in my locale is B2 is the primary LTE carrier with N5 being the NR band of choice.

B12?

Yeah, it appears as though if you do NSA you have to pick a low-band PCC if you run mid-band NR, or vice versa. Rather curious if they'll use B14 as a PCC anywhere.

As for whether n2 is DSS or not, should be trivial to check, but there's no way AT&T would be willing to remove 20 MHz of LTE capacity in favor of NR at this stage; that's gotta be DSS (and you should be able to verify that by switching back to 4G only mode and checking EARFCNs).

TMobile and Verizon will be all VoLTE here soon.  I don't see why AT&T couldn't.  Though they have a very tee tiny list of VoLTE capable devices. Some kind of technical issue because of some piece of hardware/software they opted for years ago? They don't want to put the extra effort into it? Use this as an opportunity to sell phones?

They already have a decent number of markets that lack 850.  It sucks going from a very usable LTE 700 to not being able to place a fall call due to the lack of 850.  I have even noticed that AT&T 700 LTE coverage is better than their 850 HSPA coverage in my area. VoLTE works on on my phone both TMobile and VZW, why the heck not AT&T!

I think it's just a control issue on AT&T's end as far as their VoLTE whitelist is concerned. This may just be a way to only allow the select devices they decide to work on the network.

Fun fact- you can take an AT&T sim out of a device that has VoLTE provisioning and move it to an "incompatible" device and VoLTE will work on that "incompatible" device for several minutes before AT&T's system updates with the new IMEI and kicks the phone off.

When I switched to RedPocket GMSA in December from Sprint using a Verizon Palm Phone, VoLTE was working through February before it was disabled. That was a RP sim card straight into the Palm and activated in the Palm.

What all Is going on with this site? One sector has 5 panels, the other 2 are 4, with 2 larger panels. (Mid rack) This is just a normal 2 B66 10x10 carriers with 1 B2 10x10Mhz, B2 5x5Mhz, b12, b14, B30 5x5Mhz, and N5 5Mhz, with 4g on B5.

 

Also With the Android 11 beta, and a few tweaks I was able to see all of these 5G bands available

On the Pixel 4 at least, the MVNO profile that's loaded for the SIM disables the ability to turn on VoLTE. Same for red Pocket T-Mobile. I used root to set a prop that forces the toggle to always be present in settings and VoLTE works fine on GSMA and GSMT. AT&T is now at least allowing VoLTE on MVNOs on their network. But devices need updated to allow it to be turned on.

Yeah, for the short period family was on Pure Talk, VoLTE worked on the g fast and S20, but not on the Moto X4 and E4 Plus. All four devices support VoLTE on VZW. 99.99% sure all would support VoLTE on TMo but lack of B71 on the older Motos mean I haven't checked.
