Impressive speed by AT&T! That is what mmWave is all about, providing an insane amount of capacity to high traffic areas. I know VZW can hit ~5 Gbps, but all 3 Gbps is nothing to sneeze at.
I said screw it and pulled the trigger on FirstNet. Nice download, pitiful upload from right outside the AT&T Store.
I had no problem getting approved for it. As soon as I walked in the store and said I want to set up a new line the kid asked what I did for a living and immediately said I qualify. They must be heavily incentived to sign up FirstNet subs.
Spent the evening driving around speed testing in various areas of surburban hell. There has not been a single area where T-Mobile isn't significantly faster, and I mean SIGNIFICANTLY faster than AT&T. My results pretty much reflect what you've posted and what I've seen others report. My hope is the complete rip and replace of AT&Ts gear as they migrate to 100% Ericsson in combonation with the continued expansion of their network results in long term improvements.
This is from what I like to call the premier cell tower in Western NY. It's on a very busy road, many business, chain stores & restaurants, hotels located in this area. It is a very large tower and has the most vast array of antennas and panels I've ever seen. This tower is home to all three carriers and also had Sprint gear on it before the buyout. This is the tower I was connected to the first time I broke 100 Mbps on LTE (Sprint band 41), first broke 300 Mbps on LTE (T-Mobile band 66) and first broke 1.5 Gbps on NR (T-Mobile n41). Verizon and AT&T live here too, but it's been years since I had a personal device I could run Ookla on with those two
Overall $45/month for FirstNet Unlimited Extra is pretty sweet. Unlimited talk, text, high priority data AND mobile hot spot. No slow downs based on usage and highest QCI available. Much better than the $86 Unlimited Premium PL. A few months ago when I was at my favorite place in the world, Presque Isle State Park in Erie, PA there was a FirstNet truck providing service to the area parked off to the side by the walking/bike path. Not sure the reason why, nothing was going on to my knowledge, maybe just testing or something. Would have loved to be able to connect to check it out, next time I will be able to
