    AT&T Low-Band 5G to Arrive With Samsung Phone in 2H19

    AT&T Nationwide 5G in 1st half of 2020.

    AT&T says it is intending to have a Samsung smartphone available to support its new low-band 5G network in the second half of 2019 as it announces support for those frequencies in some US markets.

    On December 9, the operator announced that it would widely supplement its existing (and expanding) millimeter wave (mmWave) 5G Mobile service with a low-band service -- using unnamed frequencies -- in the second half of this year. (See AT&T's New Nationwide, Mobile 5G Timeline and 5G in the USA: A Post-CES Update.)

    "We're planning to make 5G broadly available over low-band, or sub-6, spectrum this year and have nationwide 5G coverage in first half of 2020," an AT&T spokesperson told Light Reading over email. "We've also announced three 5G capable devices so far, including a Samsung smartphone that will be sub-6 and mmWave [millimeterwave] compatible, which we expect to have available in the second half of this year. "

    So, AT&T expects to have one Samsung smartphone supporting the 5G New Radio (5G NR) specification on millimeter wave and a lower band (or bands) by the second half of this year. As well as the Netgear Inc. (Nasdaq: NTGR) Nighthawk hotspot and another Samsung Corp. smartphone supporting mmWave 5G and multiple 4G LTE bands. (See A 5G Device Timeline for 2019.)

    The operator hasn't yet revealed what low-band frequency -- or frequencies -- it plans to use. It has, however, been rolling out 700MHz as part of its "FirstNet" project, as well as installing AWS-3 (1695-1710 MHz/1755-1780 MHz/2155-2180 MHz) and WCS (2.3GHz) mid-band frequencies. AT&T says it has been installing "5G-ready" radios for all these frequencies as part of the FirstNet public safety deployment. (See AT&T Pegs 2019 Capex Guidance in $23B Range, Despite 5G Push.)

    AT&T says it covers 500,000 square miles in the US with the FirstNet network now. Which effectively means it can switch on low-band 5G support in multiple markets now. But it is waiting for a compatible 5G smartphone, which will arrive later this year from Samsung.

    This puts AT&T in a low-band race with Sprint Corp. (NYSE: S) (2.5GHz) and T-Mobile (600MHz). All are expecting to launch low-band commercial services around the middle of this year. AT&T and T-Mobile have also promised nationwide low-band 5G service in the US in 2020. Although much appears to depend on the availability of compatible 5G devices for each carrier's chosen low-band frequencies. And the final outcome depends on what happens with the Sprint/T-Mobile merger. (See Darkness Gathers Over T-Mobile/Sprint Merger and T-Mobile Quietly Confirms 5G Network in 30 Cities.)

    Att still hasn't finished 4g. Once they finish 4g then we can talk 5g. Heck att still has tons of 3g

    AT&T Low-Band 5G to Arrive With Samsung Phone in 2H19

    A nationwide rollout of new equipment with low band 5G capable radios sounds great....Hopefully every tower they touch withFirstNet gets this equipment.

    Much better than trying to penetrate trees and buildings with the high-end frequencies like Verizon.

    Also a much better announcement than just re-labeling LTE to say 5G.

    The new radios used for B14 are 5G capable. My guess is they're going to move B12 over to 5G but that just comes from guessing they'll keep B14 as part of their lowband LTE solution. Verizon's doing the same thing with their new radios but who knows what parts of their LTE network they're looking to move to 5G. Maybe B5 to keep B13 on LTE?

    Per the article AT&T says they cover 100,000 more square miles than Verizon. Did I read that right?

    Besides that: finally a thread in the ATT forums worth reading! I will be following this one closely. Don't let this one die guys.

    I did laugh. But honestly their 2G is tiny compared to their LTE network since it only operates on Band 2.

    With T-Mobile you are way more likely to be connected to their LTE network than anything else they operate courtesy of Band 12 and now 71. Even their 3G network only covers around 260 million Americans compared to their LTE network that covers north of 325 million POPS.

    This news about AT&T is noteworthy to me because it means T-Mobile is going to have some low band 5G competition heating up which is good for everyone.

    It will most likely use B5.

    AT&T is going to use a lot of 39ghz spectrum for 5G and enhance that for coverage with low band. Verizon is certainly going to do the same thing.

    AT&T is mainly going to use 39ghz for 5G because they have a lot of it nationwide. I think them releasing this info is in a way a shot at Tmobile who's been touting 5G over band 71 as the last coming. Certainly Verizon is doing the same thing.

    None of the carriers has enough low band to roll out 5G as a low band only service. They'll have to use carrier aggregation with other other spectrum. Once they get it built they can just take slice by slice from existing in use LTE spectrum and repurpose it all to 5G as the phones become the norm over time. That's my take on it anyway.

    Just a little over a year ago the 5G spec said a minimum of 100mhz of spectrum would be necessary for to meet the 5G standard. Whether that's been watered down since I haven't seen anywhere but the only way to meet that the way it was written up then is through mmwave and or CA.

    That's how I am. I want all the carriers to improve and motivate each other to improve further

    In the end they all will use a combo of bands and resources

    It is 100 MHz channel width maximum for sub 6 GHz, 400 MHz max. above 6 GHz. No minimums that I could find.

    I will not be an early adopter of 5G handsets.

    I think wikipedia is really describing channel width blocks of 100mhz below 6ghz and 400mhz above 6ghz are part of the standard as they specifically state 5 x 20mhz CA blocks get you there.

    I can find dozens of articles pretty much confirming that

    https://www.rcrwireless.com/20171222...obile-5g-Tag10

    We consider a spectrum band to be suitable for 5G deployment if it consists of a minimum of 100 MHz of bandwidth because to deliver speeds close to 1 Gbps..............................By this definition, neither AT&T nor Verizon nor T-Mobile currently controls sufficient sub-6 GHz spectrum that is suitable for mobile 5G deployment. Only Sprint has the 100 MHz of bandwidth in the 2.5 GHz spectrum band that could support 5G deployment with user downlink speeds that could deliver 1 Gbps service. T-Mobile participated in the 600 MHz auction and was able to secure 31 MHz of this low-band spectrum in many markets nationwide. The total bandwidth available in the 600 MHz LTE Band 71 is 70 MHz, and T-Mobile obtained an average of 31 MHz, clearly not enough by itself for mobile 5G deployment.
    https://blog.3g4g.co.uk/2017/03/imt-...uirements.html

    Bandwidth: Bandwidth is the maximum aggregated system bandwidth. The bandwidth may be supported by single or multiple radio frequency (RF) carriers. The bandwidth capability of the RIT/SRIT is defined for the purpose of IMT-2020 evaluation.

    The requirement for bandwidth is at least 100 MHz.
    The RIT/SRIT shall support bandwidths up to 1 GHz for operation in higher frequency bands (e.g. above 6 GHz).

    This is where I get the info I posted about before - When I posted this in the Tmobile forum a poster came along and said the spec has changed since then but when I asked for an up to date source on the spec there were crickets.

    So when they say spectrum they mean channel bandwidth.

    https://arstechnica.com/information-...mt-2020-specs/

    The total download capacity for a single 5G mobile cell must be at least 20Gbps, the International Telecommunication Union (ITU) has decided. In contrast, the peak data rate for current LTE cells is about 1Gbps. The incoming 5G standard must also support up to 1 million connected devices per square kilometre, and the standard will require carriers to have at least 100MHz of free spectrum, scaling up to 1GHz where feasible.
    If there is a standard that is more updated than the late 2017 release I can't find it online but what seems clear is any carrier using low band and calling it 5G is going to have to overlap that entire cell area with other channels using CA to reach a 100mhz wide channel over the entire cell.

    Whether or not any of that is truly going to be the standard doesn't really matter since in the early "just inside of the tech knowledgeable" person's world of 5G where 5G-NR is a buzzword they'll basically call any site that has 5G-NR radios capable of delivering 5G despite it meeting any standard. While, yes, it can operate more efficiently using LTE bands which is what we expected LTE-A to do and may be capable in the future as serving as the backbone of radios that deliver any 100Mhz and above channels, any site that has them will fall under the term "5G" from a marketing standpoint as they are currently being deployed as a 4G/5G bridge and all the details are just secondary whether or not the results are actually there.

    Basically it's a race to see which carrier can claim they have the most 5G-NR capable radio heads installed "nationwide" at a certain time to pull the trigger on what they deem is necessary to be the first in all the marketing and then deal with the aftermath of under delivering later.

    IMT-2020 is not a standard. There is no standard yet. IMT-2020 is a document of the vision of the ITU-R for what will become the 5G standard.

    In the mean time, industry players of the 3GPP are developing specifications to submit to the ITU for what will become the 5G standard as something that can be actually economically deployed.

    There is no 100 MHz channel bandwidth minimum. That is a vision statement, and not a practical one IMHO. If there were, that would leave the carriers in the position of not being able to use their existing low and mid-band spectrum as 5G, except for Sprint. Sprint is the only one with 100 MHz of spectrum available to devote to 5G, and they don't have the money to deploy it at more than a snails pace.

    Meanwhile, LTE no longer has much marketing cachet. The carriers are pressing forward with some version of something that they can call 5G for marketing purposes. Some are sticking closer to the what is expected to be the standard than others.
