Sprint and the Firstnet RFP


bigsnake49

Recommended Posts

Does anybody know if Sprint is interested in bidding for the Firstnet RFP? It seems that AT&T is gungho about it. For those that are not aware, Firstnet is the no-profit tasked with building a national public LTE network in a 10x10 public 700MHz band. Public safety has first priority on the capacity but commercial entities, including utilities and the winning carrier's own customers may use it on a secondary-priority basis.

I had put FirstNet totally out of mind.  It has been a huge fustercluck.

 

As the Upper 700 MHz D block is band 14, not band 13, and not part of any superset band, I doubt that Sprint would or should be interested.  To make matters even sweeter, it has an inverted duplex, just like band 13 -- but a -30 MHz offset, unlike the -31 MHz offset for band 13.

So why inverted duplex is still a thing? 

 

Because uplink of one band cannot be located adjacent to downlink of another band.  Otherwise, interference problems arise.

Besides B13, is there any other Band currently used in LTE is inverted.

Yes.  Besides band 13 and band 14, band 20 (EU Digital Dividend 800 MHz) and band 24 ("LightSquared" L-Band 1500/1600 MHz) have inverted or negative duplexes.  Band 24, however, is unlikely to be utilized.

While Verizon might have the most well developed national network and probably can claim the most resilient network (generators instead of batteries for the majority of their sites), they might not be the winner. As always it really depends on the bid. If Sprint wants it badly enough, they can win it.

Almost certain compatibility with already installed band 13 700 MHz antennas would be an inherent advantage for VZW.  However, FirstNet band 14 would require new RRUs.  So, VZW probably would have to install RF multiplexers to continue to use its existing antennas.  Alternatively, VZW could replace its band 13 base stations with dual band 13/14 RRUs.  And that might be the gambit, since the Release 8 band 13 equipment is getting outdated.

And Verizon get a government subsidized network upgrade.

That could be the plan.  But other than the infrastructure update, the capacity increase could be limited by how much FirstNet gets to keep to itself.

I think Sprint should go after band 14. They it more than anyone.

Plus if the buildout is government subsidized, the money side of things is mostly covered. Additionally this will fit in well with NGN and all of their expansion projects (Cedar, Ocean) because they will already be sending crews out to work on towers - they can just have the crews install 700 RRUs with everything else.

No.  Just asserting it in an unclear post does not make it so.  Go back and read the rest of the thread.  It details some inherent disadvantages for Sprint, some inherent advantages for other operators.

What are the disadvantages you are referring to (other than the downlink uplink flipped)? I see advantages for Verizon but not disadvantages for sprint...

Well, this will be a list that reiterates some inherent disadvantages already stated and adds a few more...

  • Yet another boutique band for Sprint -- there is no band 14 ecosystem.
  • Even another set of low band antennas per sector would be required to support 700 MHz.
  • Construction requirements would dictate that Sprint build well outside of its native footprint.

Those disadvantages may not be disadvantages if Sprint won the bid. However, Sprint will be in disadvantage during the bidding process and Verizon could easily win.

Just so everybody has a better idea of practical applications here is what the public safety initiative is all about....https://www.dhs.gov/sites/default/files/publications/Fact%20Sheet_Nationwide%20Public%20Safety%20Broadband%20Network.pdf

 

Personally, I don't think it will be much better than a viable offload solution in the urban centers. The amount of data being moved by emergency services is pretty substantial. I don't see any indication of using the network for VOIP but I assume it is possible. If that happens then an even greater amount of bandwidth would be utilized. I honestly don't believe that it represents a massive advantage for any of the national operators.

Hmm... Maybe something Dish might be interested in.  Several billion to just start the network buildout. 

 

Sprint having it would be cool, but then I see issues with their current coverage area.  This will have to addressed and how Sprint is going to pay for it, unless future spectrum auctions will top off FirstNet money wallet and be fully paid for.

 

I think VZW getting it would be ideal.  I am sure that can do the fastest deployment which I think would be best for FirstNet. But then I'd expect in populated areas for there to be a lot of traffic, so how much will a carrier benefit from getting to use it?

I'm assuming the latter is more likely. In my region, they've been busily completing a full rip/replace on their band 4 equipment and installing new multi-mode band 2/4 BTSs and RRHs with dual-sector antennas (for six-sector sites). The band 13 equipment is the only thing they haven't touched at this point, so it would make a lot of sense that they're waiting to tackle it until the FirstNet deployment.

While public safety is moving a lot of data, they arent going to suddenly jump into FirstNet head first and transmit all that data.  The biggest variable to public safety will be the cost.  First, will it even be viable to jump into the system?  If your data costs double or triple, how many are really going to use it?  Secondly, the hardware costs will be astronomical.  The major public safety solution companies like Sierra Wireless/InMotion, Cradlepoint, etc do not even have a FirstNet device out of prototype planning phases.  If the hardware comes out at cost of todays devices, you are looking at 1k per vehicle to adopt this new technology.  Many public safety agencies are still using 10 year old 3G hardware.  If they dont need video transmission or large amounts of wifi sharing, 3G serves most needs adequately.  And most dont need video transmission or more than 1-2 simultaneous data connections.

 

In all that sense, especially when you factor in hardware cost, Verizon certainly is going to have to fight to lose this bid.  They may as well have the deal in hand.  Verizon will have the clout to drive the hardware costs down to a degree if they can reuse them on the public side, and public safety agencies are not going to support a carrier move to anyone besides Verizon or ATT to begin with.

Sprint could use sites build purposely for public safety to host their equipment as well, in places they currently don't have service but have spectrum. Sprint might want to low bid in those places.

The terminal equipment cost will not be insignificant and there is nothing that can be done to bring the cost down. Combining band13 and 14 into a superband might bring the cost of network equipment down.

    • Since this is kind of the general chat thread, I have to share this humorous story (at least it is to me): Since around February/March of this year, my S22U has been an absolute pain to charge. USB-C cables would immediately fall out and it progressively got worse and worse until it often took me a number of minutes to get the angle of the cable juuuussst right to get charging to occur at all (not exaggerating). The connection was so weak that even walking heavily could cause the cable to disconnect. I tried cleaning out the port with a stable, a paperclip, etc. Some dust/lint/dirt came out but the connection didn't improve one bit. Needless to say, this was a MONSTER headache and had me hating this phone. I just didn't have the finances right now for a replacement.  Which brings us to the night before last. I am angry as hell because I had spent five minutes trying to get this phone to charge and failed. I am looking in the port and I notice it doesn't look right. The walls look rough and, using a staple, the back and walls feel REALLY rough and very hard. I get some lint/dust out with the staple and it improves charging in the sense I can get it to charge but it doesn't remove any of the hard stuff. It's late and it's charging, so that's enough for now. I decide it's time to see if that hard stuff is part of the connector or not. More aggressive methods are needed! I work in a biochem lab and we have a lot of different sizes of disposable needles available. So, yesterday morning, while in the lab I grab a few different sizes of needles between 26AWG and 31 AWG. When I got home, I got to work and start probing the connector with the 26 AWG and 31 AWG needle. The stuff feels extremely hard, almost like it was part of the connector, but a bit does break off. Under examination of the bit, it's almost sandy with dust/lint embedded in it. It's not part of the connector but instead some sort of rock-hard crap! That's when I remember that I had done some rock hounding at the end of last year and in January. This involved lots of digging in very sandy/dusty soils; soils which bare more than a passing resemblance to the crap in the connector. We have our answer, this debris is basically compacted/cemented rock dust. Over time, moisture in the area combined with the compression from inserting the USB-C connector had turned it into cement. I start going nuts chiseling away at it with the 26 AWG needle. After about 5-10 minutes of constant chiseling and scraping with the 26AWG and 31AWG needles, I see the first signs of metal at the back of the connector. So it is metal around the outsides! Another 5 minutes of work and I have scraped away pretty much all of the crap in the connector. A few finishing passes with the 31AWG needle, a blast of compressed air, and it is time to see if this helped any. I plug my regular USB-C cable and holy crap it clicks into place; it hasn't done that since February! I pick up the phone and the cable has actually latched! The connector works pretty much like it did over a year ago, it's almost like having a brand new phone!
    • That's odd, they are usually almost lock step with TMO. I forgot to mention this also includes the September Security Update.
    • 417.55 MB September security update just downloaded here for S24+ unlocked   Edit:  after Sept security update install, checked and found a 13MB GP System update as well.  Still showing August 1st there however. 
    • T-Mobile is selling the rest of the 3.45GHz spectrum to Columbia Capital.  
    • Still nothing for my AT&T and Visible phones.
