That will never happen -- at least, not anytime soon. Such would displace some public safety users a second time. Not to mention, it would not make a whit of difference in the Southeast, as SouthernLINC occupies the Guard band, Expansion band, and part of the B/ILT non cellular band.

 

Sprint is just going to have to be satisfied that it finally has any <1 GHz spectrum for CDMA1X and LTE.

You're right AJ! I bit of wishful thinking on my part. On the other hand I never understood why they did not move PS down to the 700MHz PS band that is right below the 800Mhz PS band.

Absolutely. It makes little sense to 1) reconfigure the SMR 800 MHz band to protect public safety, then 2) while that process is still ongoing, open up the Upper 700 MHz D block + Public Safety 34 MHz license, which includes 12 MHz allotted to narrowband operations (a la those in the SMR 800 MHz band).

 

Call it a matter of bad timing. Had the Upper 700 MHz band been licensed a few years earlier, then public safety likely could have been relocated entirely out of the SMR 800 MHz band.

To bring some greater clarity to the SMR 900 MHz discussion, I have cooked up another of my famous graphs.

Note the interleaved nature of the SMR blocks; B/ILT blocks occupy the channels in between. At the very least, this is why Sprint cannot currently utilize its SMR 900 MHz holdings for CDMA1X or LTE.

It might be my faulty memory, but I seem to recall that there was a lot of speculative buying of 900MHz B/ILT spectrum speculating that Sprint/Nextel would be forced to buy them out.

What exactly does "B/ILT" stand for?  only thing I found via google was "B/ILT Business and Industrial Land Transportation."  Does this mean that some other form of communication is happening in those blocks between the iDen channel blocks?  Who designed this crap, a three year old?

Correct on both counts.

Oh, come on. The FCC first established SMR about 30 years ago.  And for years after that, all mobile operations were narrowband, for which the SMR configuration is well suited.  You are playing Monday morning quarterback decades after the fact.

Yes I am, I can't see how it is logical to say "Let's design this "ABABABABABABABABABAB?!?"  How about we use logic and go "AAAAAAAAAA" then "BBBBBBBBBB" and the licensee can use that block how every they need it.

Since most of the SMR operations were local, it was OK for people to reuse part of the spectrum for one area and have the other part of the spectrum in an adjacent area. with a spatial reuse pattern that minimized interference without expensive filters. Now, my question is what is Sprint going to do with this spectrum after they shut the IDEN network down. Can they trade it to Southern Co in exchange for their spectrum in the Southeast? Can they sell bits and pieces of the IDEN equipment to local companies along with the 900Mhz spectrum?

Sprint should just make an offer to buy out SoLinc from Southern Company, and Southern Company would transition to using PTToLTE from Sprint.

Yeah, but have you run this idea by Solinc lately? I don't think they are OK with it. 2, 3 4 years from now, maybe. SouthernCo, want to be in control of their own destiny. I don't blame them, really.

Sprint actually has a PTToLTE system they can demo to SoLinc that isn't complete fertilizer now with QChat over LTE. That's a big difference.

They would have a ton of sites to convert to get them the coverage they need in that area.

Solinc's coverage is really freaking solid. If Sprint wants to duplicate their coverage, then yes. Where is this PTToLTE product you're speaking about? Oh, it's demo? When they actually have a working product over their whole network, then they can have Solinc test it.

There was a guy who used to post here that had family working in SoLinc, just about everything he said has come to fruition.  SoLinc isn't so much a public mobile company, but a two-way radio service for Southern Companies.  They don't care if it loses money, because the overall company rakes it in hand over fist and they need the radio service.

 

Sprint couldn't offer SoLinc enough money for its spectrum to get them to say yes...

      Someone told me a couple years ago, that there were problems getting certain modems to aggregate overlapping spectrum even if the overlapping parts were actually blanked. So I think there might be firmware issues that need to be resolved first, which T-Mobile might not consider worth the effort for 4MHz at this time.

      Tbh not that surprising. Every ISP seems to want to have an MVNO to pitch to their customers to make them stickier and maybe make some money in the process. And unlike USCC the MVNO should be able to cover TDS's entire wireline area, with infrastructure costs that are borne by someone else. Entertaining, yes. Surprising, not really...particularly when competing against Comcast or Spectrum, or even eventually T-Mobile fixed + mobile. This also strengthens my bet that they'll rebrand all their fixed wireless stuff as TDS, as that runs on spectrum they're keeping for now.

      No? RCS on Google messages works great for me, messages between anyone with RCS enabled go through with no problems. Don't remember the last time I had an issue. I only have issues with people on iPhones on different carriers from T-Mobile.

      Has anyone experienced a ridiculous amount of difficulty with Google messages with RCS enabled?  It has been a train wreck for me for the past year so I now use WhatsApp.  That works very well for all of us.... Android and iOS.

      Probably not worth the fiddling given that that's a few percent of the band. Also, if they really wanted to push my assumption is there are still guard bands in play for the n41 carriers so they could fit two "100 MHz" carriers into 194 MHz anyway. Looks like minimum guard band is less than 1 MHz and a 100 MHz channel is only 273 30 KHz resource blocks, which is a bit over 80 MHz total, so if they really wanted to pull another 5% or so capacity out they could.
