The problem with Dish is that they have 2 problems:  1) They need more spectrum and 2) They need a wireless carrier to deploy this spectrum.  Sprint wouldn't mind selling Dish some of the 2.5 GHz spectrum but the thing is they will still be begging someone to help build their network for them. His only options left really are Tmobile, Leap and US Cellular and I am not sure how interested Tmobile USA is.  I know Deutsch Telekom wants out of the US market but will it be that desperate to accept Dish's terms.  We will have to see but in terms of Dish's view getting additional spectrum does not solve all their problems.  Dish is on the clock to build out the S-band spectrum footprint or risk losing it and they need to start creating a plan because that time will be here before you know it.

Isn't the TMUS/MPCS deal going to make the combined company publicly listed, and DT will just be a large shareholder? Then DT can just slowly sell off their TMUS/MPCS shares. So DT already has an exit strategy. They don't have to sell it all off at once now.

Hummm, I have never heard that before. I ran several tests on multiple servers and they were all right around that speed.

What other PCS spectrum does Spring have in this market? Could they have put up a 10x10 LTE here?

I have two boys who online game at the same time. Add to that a couple of their friends who bring their laptops over so they can all play together. That is really nothing new in our house though. Friends with Ipod Touchs, DSs, phones and laptops. The guest network password is posted on the fridge.

 

A few months ago the boys started complaining. It was a while before I took them seriously. Then I noticed the lag in loading web pages when they were both playing. I know I said I read Comcast is increasing the performance from 15 down but I think in our area we had 12/2.

 

Part of the problem might be "buffer bloat". Instead of dropping packets, and thus throttling back on upload or download speed,  in a timely manner so devices share the internet equally, router buffers fill up in increase latency before dropping packets. Thus things like Skype or web surfing, where latency is more important that having a LOT of bandwidth.

No, 3GPP airlinks do not require additional guard bands.  In a Eurasian spectrum centric move, they already include internal guard bands.  A 5 MHz FDD LTE carrier, for example, occupies really only 4.5 MHz.  To illustrate, see my spectrum analyzer sweep in the RSRP article:

So the question becomes, with 14Mhz of spectrum, would Sprint opt to add a 1.4x1.4 LTE carrier after they drop the 1xA carrier, or would they refarm to something like a pair of 3x3 LTE carriers on ESMR? Too bad you can't do a 7x7 carrier on LTE....

I agree that the ESMR 1xA carrier would be the last CDMA carrier that Sprint would get rid of.  Since Sprint has 7x7 (14 MHz) of ESMR spectrum in most areas of the country, I wonder if they could at some point refarm that last CDMA carrier to deploy a 1.4 x 1.4 MHz LTE carrier.  The spectrum needed is just slightly larger than a CDMA carrier (1.25 x 1.25 MHz)

Maybe in this case, they'd refarm the ESMR so they had a pair of 3x3 LTE carriers, instead of 5x5 LTE and a 1xA (1.25x1.25). How big do the guard bands need to be?

Why would they get rid of that 1xA carrier?

I don't think they would, that's exactly my point. Even in 10 years when all the new phones are doing VoLTE, dropping the 1xA carrier on ESMR won't give them enough additional spectrum to enlarge their 5x5 LTE carrier on ESMR. My guess is that this would be the very last CDMA carrier that Sprint will get rid of.

^{Given the size of Sprint's 800 Mhz spectrum holdings (they can't fit MORE than a 5x5 LTE carrier there, even if they got rid of the 1xA carrier), I don't know why they'd be in any hurry to get rid of the 1xA carrier on 800Mhz.}

I know that's the case in the Brookings/Sioux Falls area of SD, as that is run by an affiliate(Swiftel), but the "dakotas" market also includes Western Minnesota, Basically everything from Alexandria west.

I saw that there wasn't a network vision thread for the Dakotas market yet. So I might as well get it rolling. Rep at the sprint store told me they heard work will be starting in the Fargo area July 1st. Alexandria area will also be starting this summer. And I think someone in the Minnesota thread mentioned some backhaul is being done in the Fergus Falls area.
