    Bands Used for 5G Nationwide

    So Verizon is definitely using n5 and n2, but have any of you spotted n66 or n77? (n77 is the NR equivalent of LTE Band 48, CBRS, because it also includes the upcoming C-Band spectrum.)

    I’m certain they’re also going to add n46 (5G unlicensed in 5 GHz spectrum) and whichever band will equate to unlicensed 6 GHz once it becomes available, but obviously that remains to be seen because no 5G devices support unlicensed 5G yet AFAIK.

    n5 is currently the only band online for “nationwide” 5G-NR.

    N77 is only Cband, has nothing to do with CBRS, CBRS on 5G will be N48

    Then why does n77 supersede n48, and why do new Verizon phones only have n77 and not n48?

    VVivian is indeed correct, Per Wikipedia n48 (CBRS) is 3550-3700mhz, n77, n78, and n79 are labelled as C-Band. n77 is 3300-4200 and n78 is 3300-3800 (same 3500mhz center frequency as n48, so probably easier to use existing CBRS antenna compared to n77). n79 is 4400-5000, I suppose this is like an upper C-Band.

    4G's had a few bands like that (band 66/band 4), it might be nice for 5G signal apps to show that info (like "n78" but also that it's within the n48 CBRS range.)

    n78 will only be for use in Canada as per iPhone 12 specs in the FCC docs. CBRS will be used as a supplementary LTE downlink only carrier for some time. According to the specs of the 12, n77 will run on 3700-3980 MHz and CBRS/B48 on 3550-3700. Verizon won't run n77 on that 150 MHz of BW.

    So according to you when Verizon decide to use CBRS for 5G people will need to buy new phones even though many current phones have an existing radio that will function just fine. Also band 79 also over the lower 100 MHz of C-band which the only part of c-band that will be available for use until Dec 2023. So once again band 78 radio should work fine but once again force people to buy new phones. In Dec 2021 C-band will be available for use and no phones will have support for it. BRILLIANT!

    3700-3980 MHz is what the iPhone was tested under for n77, which is the spectrum going up for auction starting this December according to the PDF I'm reading on the FCC site for Auction 107 unless something has changed. So the iPhone will have it covered

    It does seem a bit confusing, (especially a phone supporting n77, but only 3700-3980 out of possible 3300-4200).

    It seems like with as many bands as there are (including ones that are supersets of others, the bands where there'll be US, EU, and Asia/Pacific bands in some cases so they cover an overlapping frequency range but with a different band plans, etc.), it seems like it would make things easier for 5G sites to be able to specify service in terms of receive frequency and width, transmit frequency and width (rather than using bands and channels), and regulatory power limits. Instead of the phone supporting an ever-increasing list of bands that are beginning to cover a large percentage of the spectrum, it'd be like "600-950mhz, 1700-2500mhz, 3700-3980mhz" or whatever the hardware actually supports. This would be virtually impossible from a regulatory standpoint I suspect. Oh well, bands it is!

    Bands Used for 5G Nationwide

    While Apple generally does a good job of designing for product longevity, the reality is that C-band won’t be even begin to roll out (in earnest) until 2022. By then, the iPhone 12 will be nearing 2 years old.

    And we don’t even know who will win the “currently” supported narrow slice of n77. It could be Dish (-: for all we know.

    I wouldn’t hold my breath for any/any useful C-band support on the 12. But we could be pleasantly surprised.

    Maybe Verizon being at the iPhone 12 launch event is more fortuitous than we initially realized (-:

    I also found this document which I thought was useful.

    Verizon can be install C-band equipment now and in no reason why antennas deigns for CBRS can't also be used for-band since the frequencies are right next to each other. A soon as Dec 2021 gets here Virizon could do an instant launch in most of the 50 markets if they wanted too
