    AT&T Says Nationwide Low-Band 5G Will Arrive in 2020

    https://www.lightreading.com/mobile/...d/d-id/752975?

    AT&T says it is on track to deliver nationwide, mobile 5G in the first half of next year.

    The operator says that it has completed 60% of its 700MHz 4G public safety FirstNet deployment now, which is 5G-ready for AT&T's low-band spectrum deployment in 2020.

    "We're on track for nationwide 5G in the first half of next year," said CEO Randall Stephenson on the operator's second-quarter earnings conference call. AT&T currently has its high-band 39GHz millimeter-wave networks up in 20 markets in the US.

    The CEO, however, is especially bullish on its FirstNet deployments for 5G. "It's allowing us to deploy this 5G hardware with one touch on the cell site," he says. The FirstNet deployment is expected to be 70% finished by the end of the year.

    LTE 14 isn’t certified for NR yet. It’s n5.

    AT&T's commercial 4G network, with LAA-LTE.

    So they'll put up a single 5x5 on n5 sharing B5 with HSPA+ so that one of the 7 channels that be CA'ed together is 20% faster than it would be on LTE... all so they can crayon in the map with actual 5G. Riiiiiiiiiiiiight.

    At least it will still be blazingly fast, since the other bands will still be carrying most of the load on LTE including wider channels on B2/4/12/14/30 depending on the market.

    Meanwhile, they will probably still have a few T1-backhauled 3G towers hanging around in ME, MN, WI, OR, or somewhere like that.

    Also, does this mean bye-bye to B5 LTE outside of the few markets where AT&T owns both sides of the CLR spectrum?

    The article only mentions 700 Mhz. It doesn't say anything about 850 Mhz.

    That 700 MHz spectrum they are referring to is B14/FirstNet spectrum. They are doing full upgrades to the sites which will support 5G. I wouldn't be surprised if they started deploying n2 along with n5 next year.

    The way I read it is that they are doing one set of upgrades, putting 5G software-upgradable RRUs up while they are doing the B14-capable RRUs and panels. They're sort of two different things, it's just getting done all at once. And, not mentioned in the article is that I believe on sites they are touching, they are deploying all available bands as well.

    I kind of doubt that they are going to do much beyond a single 5x5, at least for a few years. It just doesn't make sense given how few 5G phones are out there compared to the relative efficiency of each. And it's not like having a tiny amount of 5G will hurt them, it's not like previous generations where you were on one or the other. AFAICT, the phones can CA together 4G and 5G at the same time.

    The article is incorrect and tech journalists need to have their facts straight.

    All equipment being added onto new sites (or a very large percentage of it) includes radio heads capable of broadcasting n5, as that is the only lowband certified band in existence within the United States as of 7/24/2019 that AT&T can use.

    They're using DSS (Dynamic Spectrum Sharing) for n5. Presumably because this is the only option without kicking users off existing LTE B5.

    No worries here, AT&T doesn't have 850 in our area (we're a former Edge Wireless market), it's owned by U.S. Cellular (A Band) and Verizon (B Band). Hopefully, in the future, we won't need an Igloo cooler to put our 5G phone in, either.

    Is DSS actually working? If they do that, it's largely just going to end up being used as LTE for the time being. Even if they killed B5 LTE, it wouldn't really hurt them in markets where they have B12 available now that they also have B2/4/14/29/30 available in most markets, and at least B14/30 nationwide.

    Sub-6 5G should work fine. It's the mmWave stuff that's causing issues due to either the frequency or the bandwidth involved.

    Any equipment that has been installed and is 5G ready will be updated to 5G next year and be able to use Dynamic Spectrum sharing (that's Ericsson's term for it) will allow all the spectrum to be used on an as needed basis.

    Sprint's already doing this where Samsung is their vendor - Samsung calls it something else but its part of the 5G spec. This is unlike the move to 4G where they had to dedicate spectrum for one use or the other. Nokia and Ericsson are behind them in rolling this out.

    In 2020 all carriers will have this capability with all spectrum on already installed 5G ready equipment.

    I’ve found that if you add a year or two to the projected dates of these projects, it’s usually closer to reality versus the the PR releases coming from the providers.

    Where do you see a T1 site in MN? Curious.

    I think AT&T will go all in on dynamic spectrum sharing. That will give them a big 5G footprint but speed will lack if they use band 5 cause of the smaller size block. From previous articles you can tell they also wanna use up the CBRS spectrum. The only problem is the lack of small cells so AT&T won’t get those blazing fast 5G speeds on sub 6Mhz.
