AT&T LTE and Network Discussion


Trip

Recommended Posts

Sector IDs (per my own experience and reports):

01-06 850 MHz (CLR)

08-0D 1.9 GHz (PCS)

0F-14 700 MHz (lower 700)

16-1B 2.1/1.7 GHz (AWS)

95-9A 2.3 GHz (WCS)

D7-DC 700 MHz (upper 700--some areas)

DD-E2 700 MHz (upper 700--some areas)

As of this writing, I'm going from memory and will try to add more information from my logs later in the day.

Around here in Louisville, KY band 5 is being added as part of the network upgrades adding bands 14 and and 66. There is pretty good coverage of b5/b14/b66 across the city now.

I think a new site in Prince William County, VA has Band 5.  I hope to check on Friday.

Do you have a picture of the new site by chance? I found a new site over in Jeffersonville, IN awhile back that was only one antenna panel per sector, vs the usual 3 to 4 per sector on everything else around here. The single antenna panel was very similar to Sprint's Hexadecaport antenna they started deploying. Last time I was over there it was only broadcasting bands 4/12 though.

Up in Seattle, AT&T has 10x10 B12, 5 MHz B29, 5x5 B5, 20x20 B2 and 10x10 B30 live on pretty much every site—even wooden utility poles. B14 is slowly starting to pop up but their deployment is definitely still in its early stages.

In Champaign, IL, AT&T has the densest network although they have been really sloppy about getting all of their spectrum on air on every site. Some sites are L700/L800/L1900, others have AWS and/or WCS LTE live too but lack CLR LTE, etc.

Overall AT&T’s network reliability is second to probably only Sprint for it seems the equipment AT&T is using has considerably poorer range/propagation than the equipment Sprint is using. When broadcasted from the same location at the same elevation and angle, AT&T L700 drops out when Sprint L800 is at -112 to -114 RSRP. That being said, AT&T devices do hold onto LTE for dear life when it is available. Their qRxLevMin on lowband LTE is set to -124 dBm, and if I ever drop to WCDMA/HSPA, my iPhone always jumps back to LTE in 15-20 seconds.

T-Mobile lacks lowband spectrum in the Champaign market which immediately disqualifies them (for indoor coverage is challenging) and Verizon’s site density is awful.

AT&T widened their AWS from a 10x10 MHz channel (EARFCN 2100/66586) to a 20x20 MHz channel (EARFCN 2050/66536) after what I would guess is acquiring the A block license from Nsight in Duluth, MN. This happened Tuesday night into Wednesday morning.

Is that the only 20x20 in Duluth? TMobile is 10x10 B2 and 4x4. Looks like they're also deploying B71 not sure what the current BW is. Vzw is 15x15 B4, 5x5 B2 10x10 B13 and also got 10x10 66 not sure if they deployed that yet

At our location we have 10MHz band 30, 10 and 5MHz^2 band 4, 15MHz band 2, 10MHz band 12 active on the network; I see firstnet in the network scan but won't have a band 14 enabled radio for a month or so. We have a two routers with detailed logging enabled, one is stationary and one is mobile. How should we best contribute data to this thread?

AT&T has a second 5 megahertz PCS carrier where I live. They also have 10 megahertz of band 12 deployed 10 megahertz of band 29 and 10 megahertz a band 30 deployed where I live. The only Spectrum that's not the point on LTE is band 5 which is relegated to HSPA.

H1900 5MHz here, everything else is LTE. No band 5 license in our area.

Well here it is deployed on the secondary 5 megahertz carrier so they don't have a contiguous PCS license for this area.

Our area is actually sold under an old Cingular affiliate, Horry Telephone Cooperative. We have a pair of Corporate stores in town for wireless subscribers and whatever media ATT bought last week. HTC is the fiber and backbone provider for our area.

They were slow to roll out HSPA here, so ATT made a big push a couple years ago in the area to update base stations. It seems to have worked out; updating to bands 2/30 in an overlay went smooth right after the 2g shutdown. It looks like those will be touched again with band 14, and 30 will now be coming to most sites. Bands 4/12 are active on every site.

Have you seen any ATT small cells? I haven't yet outside of COWs.

Where I live there is no densification. So the only carry that's densified here is Verizon. But then all the carriers in my town lack densification due to township bureaucracy and red tape.

Yeah it is. T-Mobile’s widest channel is 10 MHz (AWS and PCS), Verizon has 15 MHz B4, but can go 20 MHz once they decide to attach the G block AWS-3 to it, and they also have J block (a 10 MHz block). Not used to seeing uploads this high so far north!

T-Mobile's why is channel where I live is a 20 megahertz band 4 carrier.

Here's AT&T Band 5 in Prince William County:  https://imgur.com/a/A6x70Xe

I tried locking to Band 5 in other places a few times along the way and did not see any additional Band 5.  This site also has Band 14, on top of the displayed 17/2/4/30.  I wonder if it has Band 66 as well.  (Didn't think to check.)

Couldn't get a good look at the antenna as it was getting dark and it was cloudy and I was on I-66.  Sorry.

I'm seeing a lot of sites in Louisville and Lexington KY being converted from the traditional 3 sector to 4 or 6 sector sites. 

4 Sector site, The sector on the right side has the new dual zone antennas while the sector on the left still has the original setup. This site had just received the network upgrades to add bands 5, 14, and 66 about a month or two before this conversion. 

https://imgur.com/ltLptgE

This site in Lexington has just been converted to a 6 sector site. New antenna panels all the way around. This site also has about 4 or 5 unique GCIs broadcasting from it across all 6 sectors. Bands 2, 4, 5, 12, 14, 30, and 66 are all live.

AT&T currently has 160 mhz of deployed spectrum in Louisville, KY.

Band 2: 20x20 (08-0D) + 5x5 (B5-BA)

Band 4: 10x10 (16-1B) + 5x5 (AB-B0)

Band 5: 5x5 (01-06)

Band 12: 10x10 (0F-14)

Band 14: 10x10 (BF-C4)

Band 30: 5x5 (95-9A) (was 10x10 but was reduced a few months ago, I never found out why)

Band 66: 10x10 (I've still only seen true B66 in CA SCC, haven't picked up any GCI info for it yet for here.)

 

South of Louisville Band 2 changes to the following due to Bluegrass Cellular owning 5mhz in the middle of the 20x20 carrier.

10x10 (08-0D), 5x5 (B5-BA), and 5x5 (D3-D8)

    • As Dkoellerwx said, everything gets swapped out, including ground equipment. They are also adding generators to a bunch of Sprint Keep sites in Northern Utah. My understanding is that most Sprint keep sites will get three new T-Mobile panels per sector for the entire spectrum portfolio - 600, 700, 1900, 2100, 2500. 
    • At least a few sites in STL are now at 100 MHz.
    • 100 MHz n41 is live in Austin and...Bentonville, Arkansas. Guessing this went live on Tuesday or Wednesday in Austin; network was acting a bit wonky on Tuesday. Noticed it yesterday, as I'm still a little too far away at home to catch n41. Peak speed in Bentonville 1/3 mi from the site was 675-700 Mbps down, 80-90 Mbps up, with the upload speed only possible with a 20 MHz B66 anchor...which seems congested at times. They also have 5 MHz B2 here as an anchor, which predictably leads to slow uploads. n71 is 15x15 here. Sprint B25 is two 5x5 channels. Weirdly, seems like I'm being routed through Nashville, so latency is rather high, and tethering performance is somehow quite poor...maybe it's due to congestion on the PCC meaning that the difference between on-phone and tethered priority is the difference between a usable connection and...not. Also, VZW (with the old Alltel SID for CDMA) is what you end up using inside the Crystal Bridges museum, though the area has WiFi so not the end of the world.
    • The Sprint site at 520/202 was decommissioned a few weeks ago. Everything was pulled off the pole. 
    • It looks like N5 supports 5, 10, 15, and 20 MHz channel widths. I wonder how long they'll wait before they make a change to be able to use more of that spectrum for N5. Possible options I see: Use 15x15 as B26/N5 using DSS (If thats an option, or would it have to match and be N26?) 5x5 as B5 LTE for older phones and that still leaves 5x5 for HSPA.  A more aggressive option would be to use 20x20 for N5 exclusively and 5x5 for HSPA. This still leaves 10x10 B12 and 10x10 B14 for older phones for low band. Hopefully they enable SA if they go this route. Since I believe you can't aggregate low band LTE with low band NR in most cases, phones using the N5 carrier would not be touching the B12 and B14 carriers. If they enable SA on the 20x20 N5 carrier it would also help free up their limited midband spectrum for older non-NR phones. That would also prevent falling back to LTE only inside a building just because the mid-band anchor band was too weak. In Daytona AT&T was broadcasting 5x5 B2, 10x10 B66, and 10x10 B30 and that was it for midband.
