Future low band

Recommended Posts

https://transition.fcc.gov/pshs/docs/T-Band_FactSheet_July2016.pdf

Possibly 42MHz added for cellular from 470-512MHz here? Would this be TDD?

After 2024, does this mean that any licenses remaining can be purchased and utilized for cellular?  At this time, would Sprint be able to purchases licenses from any PS or CI license holders? This covers 809-815MHz.  Not sure if using the expansion band or guard band would be possible (815-817MHz), though that is largely where SoLinc sits now?  Do we know if Southern Linc has any intentions to participate in these auctions and widen their license holidings?

Hard to say. There isn't much duplex spacing so I'd say possibly although not certainly. I wouldn't be surprised if the lower and upper part of the T-band were FDD and there were non-paired chunks of spectrum inbetween. This is how the lower 700 MHz band is set up. For those unfamiliar, see here:

I'm not sure if Sprint will be able to pick up spectrum here. Maybe someone else more knowledgeable can chime in here. 

SoLINC operates directly below Sprint, in the expansion band. Their 1.4 MHz LTE carrier is centered at 816.6/861.6 MHz. If they are interested in acquiring licenses, it will only be in their limited coverage area. As of today, they haven't made any public statements regarding acquiring spectrum.

So they could still do three blocks off that, beings that it would be 5MHz blocks instead of 6.  It would be just like Lower 700MHz except with 1MHz guards on both sides maybe. Or even like 600MHz, 10/11MHz in the middle of guard band.

Looking at it, why does 700L allow for 12x12 as usable DL spectrum between the links, but the 600MHz guard band is just that, guard band.

Here is some 900MHz for mobile broadband, maybe just for CI.  Would be a 3x3 block at 897.5-900.5 / 936.5-939.6 initially between reallocation of 896-901 / 935-940.  If future need warranted, they have the option to add a second 1.4x1.4 channel.

This possible 10MHz for LTE would put this in LTE Band 8.

IIRC Sprint owned 3x3MHz in 900MHz range.  What frequencies was that at?
