Not just with AT&T, Sprint swaps spectrum with T-Mobile and VZW, too.

Sprint 4G Rollout Updates

Friday, March 4, 2016 - 8:25 AM MST

 

A little over two weeks ago, S4GRU published an article detailing a multi-market PCS 1900 MHz swap between Sprint and AT&T that increased spectrum contiguity for both operators in several markets. In that article, we mentioned how that spectrum swap might be the first of many, as there are numerous other markets in which Sprint and other licensees could mutually benefit by realigning disparate spectrum holdings into larger contiguous stretches for more efficient LTE spectrum utilization.

 

And late last week, that expectation came to the fore. It was discovered that AT&T was not the only dance partner. Rather, T-Mobile and VZW also entered the fray, as Sprint and both operators had contemporaneously filed PCS spectrum assignment applications with the FCC.

 

 

Results of the Latest Spectrum Swap

As seen in the embedded screenshot, Sprint primarily is targeting additional spectrum in the PCS C block. Detailed in our last article, the PCS C block is adjacent to the PCS G block in which Sprint's existing 5 MHz FDD Band 25 LTE carrier is deployed. These swaps pave the way in a greater number of markets for expansion from that 5 MHz FDD carrier to a 10-15-20 MHz FDD carrier and subsequent higher maximum speeds in Band 25.

 

In total, about 50 million POPs so far will be affected by the spectrum transactions in these pending agreements among Sprint and AT&T, T-Mobile, and VZW. Furthermore, this may not be where the story ends. Once the FCC approves these applications, other PCS spectrum realignment among the big four operators may follow. Sprint also may pursue spectrum deals with smaller operators.

 

Stay tuned. S4GRU will have the scoop.

Great article. It's good to see the carriers actually somewhat work with each other.

What do the colors mean?  Yellow is what Sprint ended up receiving?  Green is current holdings?

Green is the G-block so yes that is what Sprint currently owns already.

 

 

There's still a lot of trading to be done.

 

 

That is definitely true.

This is great to see. I had always wondered why more and more carriers weren't trading their PCS spectrum to make it more contiguous across their footprint. Being such an old band, it is very random since it's been thru a lot of acquisitions for most carriers. Hopefully they continue trading so all carriers can benefit from more contiguous spectrum, considering all big 4 use it for LTE (band 2/25).

Good.  Hopefully these get approved asap.  FCC should prioritize these and ask for me spectrum realignment!

 

Whenever this is all said and done, I wonder how much extra usable spectrum will be gained across PCS.  With the reconfiguration I'd imagine the carriers would gain some efficiency in guard band reductions and eliminations.

Does this mean also Band 25 could be 20Mhz? instead of 5Mhz in markets

Yep, as soon as they get rid of EVDO and 1x on 1900MHz

When ever this might happen..... I still find 1x and EVDO in a lot of cold and far places in Oregon / Washington once you leave the corridor areas. Makes me sad :(

1x will probably remain until 2020. Probably be limited to 1x 800. Voice will start being offloaded to VOLTE after the network is densified.

Usually it's tough because there is existing consumer traffic on the spectrum so you have to be smart about it.

Doing these swaps allows Sprint to do 10X10 which allows for up to 75mbps. anything higher they will need to thin out or shutdown CDMA or Buy more FDD spectrum.

Any idea on timeline of when we will see the additional spectrum added in after the swaps.

The fcc has to approve it first and we dont know how long thats going to take.

Any way I can tell the BW I am connected to?

 

I am using SignalCheckPro on a Nexus 5X.

Nope, not really.  The EARFCN may give a clue as to carrier bandwidth, but it is not definite.

Ok. I was hoping one of the engineering screens would show this but so far I haven't found anything.

For that, you need a Samsung or an Apple.

I hope the FCC hurries up, it seems like these two applications are dragging out longer than the AT&T application. A status of 'I - inactive' isn't reassuring.

    • Ah... to get back to test-the-window mode, first we select Shutdown from the menu.  That shuts the unit down and gets it back to the original state (that it arrived in the box).  Then hold down the hidden button on the front for 5 seconds and wait for the unit to power back up.  Then I can access test-the-window mode again. Funny thing is that when I take the Magic Box outside and point it directly at the cell tower, the maximum that I get is 12 (out of 100).  But when I put it in a particular window, I can get 16.  So I'm using that.  It is still showing Band 25, but SpeedTest is reporting a better number now than I had before in a different window.  Scott Thanks,    
    • I can do the menu option and 30-second power cycle to restart, but how do I get back to the initial test-the-window mode? Also, lilotimz's screenshots show Relay on Band 41.  But my Relay screen shows Band 25.  My understanding was the the Magic Box only worked on Band 41 based on the Sprint FAQ:   https://community.sprint.com/t5/tkb/articleprintpage/tkb-id/MagicBox%40tkb/article-id/1 Will my phone work with Magic Box? Magic Box operates on LTE 2.5GHz frequency (Band 41), so only devices with this capability will work with it.  Most newer smartphones will work but you'll need to check your device's specifications for LTE 2.5 GHz to be sure. So how do I get back to test-the-window mode?  And how do I get my Magic Box to Band 41 ?  I've tried different windows, rotating it 90 degrees, and angling it.  It seems to always prefer Band 25.  I do have Band 41 here, but Band 25 seems stronger... Thanks, Scott      
    • I'd recommend trying to run setup again.  I've found that the MB picks up far better B41 signal than my phone does.  
    • ...Also, the 3 screens are accessible by touching the screen, then selecting GPS, LTE, or Relay.  The 4 menu options are accessible by touching the little square icon in the upper-right corner.   Scott  
    • I received my Sprint Magic Box and hooked it up.  I was never able to get the "button" that the two arrows point to to work, so I plugged it in. It took about 20 minutes to initialize and lock-in.  There are 3 screens:  GPS, LTE, Relay. On the Relay screen, it says Band 25.  I assume that means that it is communicating with the Sprint tower on Band 25.   But I thought the whole point was to use Band 41. I tried a couple of different windows, and even flipped the unit sideways to see if it made any difference.  The signal to my cell phone went from -114 to -64, so the Magic Box certainly helps with the indoor signal. That's to be expected; according to the front panel, the Magic Box is transmitting a 25 dBm signal.  However, my Speedtest speed is still 4 Mbps. Other than the 3 screens (GPS, LTE, Relay), and the 4 menu options (Change Time Format, More Info, Other Actions, Re-Run Setup), I can't find any other settings. One of the screens says that the Magic Box Technical Support phone number is 844-463-3194, but I haven't tried calling yet.  I don't want them to say, "it doesn't work for you, mail it back".   Is there any way to lock the Magic Box to Band 41 ?    Sprint's Magic Box checker said that I'm in an eligible zone, the coverage map shows I'm in a Band 41 zone, and prior to the Magic box my phone communicated with the Sprint tower on Band 41.  But for the past 3 days , the Relay screen says that the Magic Box is on Band 25. With correspondingly with poor Mbps. Thanks, Scott
