600 MHz auction results posted and transition schedule

My question would be "how hard is it to actually retune the gear?"  I'm assuming the 850 MHz gear will need to be replaced when 2G/3G is sunset in that band anyway, but is most of the 700 MHz gear the type that could theoretically get a software update and then be easily shifted by a few MHz?

 

And I'm wondering if with some creative shifting in 700 MHz, you couldn't squeeze a 5x5 out of it.  Recall that Verizon is sitting on 11 MHz wide channels as well, and there's D and E block each on 6 MHz.  That means you've got a total of 10 MHz sitting there with nothing going on, just scattered throughout 700 MHz.

Antennas are antennas, you can broadcast or recieve any technology through them. They would still be supporting the same range of spectrum, it would just be divided up differently. It would be the basestations that would have to be updated.

I know that much; I thought it was obvious.  I was referring specifically to the base station equipment.  Is the hardware in general deployment software upgradable or configurable such that it could be shifted by a few MHz one way or the other?

 

 

How much of difference will 600mhz be compared to 800? I know lower the frequency means better the coverage and indoor penetration but will it be noticeable?

 

Probably not very noticeable.  Part of the problem is going to be that the antennas in the phones are going to start being electrically short in the smaller devices so you lose the benefit to some degree.  I suspect it won't appear too terribly different from 800.

About 200 MHz.

I'm not against redoing 700Mhz, but between the two, there is much more to gain from reworking the 850Mhz licenses (5x5) than from 700Mhz (3x3). Also, you can use the relicensing of 850Mhz to address markets where one provider holds both sides of the license. Incumbent providers of the A or B license would each recieve neighboring 5x5 blocks (10x10) in the new arrangement, leaving a new 5x5 block to be auctioned off. In markets where the incumbent holds both sides of the license, they would be given a third block, so they would have 15x15, thus freeing up two 5x5 blocks for other carriers. Also, no company would be allowed to acquire more than 30Mhz of cell 850 spectrum from this point forward.

 

We just got 700Mhz deployed. Let's wait until VoLTE is mature and then we can go back and create this 3x3 channel in 700Mhz.

Actually, 700MHz realignment (if we follow US 700 band plan) could eliminate DTV 51 issues.

 

The APT 700MHz band plan has a guard built in at 698-703 MHz (5MHz) which we know is suitable for DTV/Cellular service protection. By rebanding US Lower 700MHz paired blocks to 5MHz FDD each, we can create a 3MHz guard against DTV 51. That would permit 3MHz LTE carriers in A block during the period in which DTV 51 is still in operation (implicitly expanding the guard to 5MHz on uplink by not using the lower 2MHz of the A block). A 3MHz FDD carrier is better than no carrier at all.

 

If we wanted to be really radical to maximize spectral efficiency and open up more usable blocks on 700MHz for use and auction, we could reband to the APT band plan. That would be difficult and require a broad range of supporters in the industry, though.

So any ideas or theories on how much spectrum sprint will try for in the auctions?  im hoping for at least 25MHz so they can do 1xA on 2x 1.5 carriers and a 2x 5x5MHz LTE carriers ( 1 10x10 would be nice to)

Why would they go and deploy more cdma carriers on new spectrum?

I'd imagine that they would try to acquire nationwide 5x5mhz and it would be used for LTE only being that voLTE is starting to become mainstream. Also the 600mhz spectrum is going to be really expensive so I don't see Sprint buying much when they have loads of 2.5ghz spectrum.

No new CDMA2000 bands will be standardized -- 3GPP2 is shutting down.  Any 600 MHz spectrum will be LTE or bust.

so then why are they doing 1x on 800MHz? why not just use it for a wider LTE channel and do VoLTE?

 

How could Sprint do a "wider LTE channel" within its licensed SMR 800 MHz spectrum?  If you answer that question, then you have answered your question.

I dunno i thought they had enough to deploy a 5x5 carrier and then i thought i read a 1.5x1.5 1x carrier. are you telling me they cant do 6.5x6.5 Lte carriers? like software and antennas cant handle the extra 1.5MHz on each channel?

A 6.5 MHz FDD LTE carrier does not exist.  So, take your pick:  1.4 MHz FDD, 3 MHz FDD, or 5 MHz FDD.  The next step up is 10 MHz FDD -- not possible in Sprint's SMR 800 MHz allocation.

 

You can propose carrier aggregation.  But no one wants to waste 2x carrier aggregation on just 1.4 MHz FDD and 5 MHz FDD.

 

In the end, the band class 10 CDMA1X 800 carrier is like a gift.  It takes advantage of the odds and ends that would otherwise go fallow.

no heay im not saying its a bad idea at all i just dont get why carriers halfto be 5x or 10x. i mean seriously if sprint has the spectrum why couldn't the software or panels support such a thing?

That's what was standardized by 3gpp.

The broadcasters also want the FCC to set a target of getting at least 126 MHz of spectrum from broadcasters for the auction

600MHz to 700MHz does not = 100MHz? how does it come out to 126MHz? does it go up higher in the frequency band or lower down into the 500s?

 

 

so confused.....

There is no amount right now as broadcasters have to give it up, but if they want 124 it will have to extend into the 500 range.

AT&T, Verizon, Sprint, T-Mobile and broadcasters warn FCC about interference issues in 600 MHz auction

 

March 17, 2015 | By Phil Goldstein

 

 

The FCC's incentive auction of 600 MHz broadcast TV spectrum is scheduled to start in a little under year from now, and many technical rules need to be resolved between now and then. However, wireless carriers and broadcasters seem to be unified on one key issue: They want the FCC to change its plans for dealing with "impaired" spectrum, or spectrum that will have too much interference to be used.

 

Specifically, carriers, CTIA and broadcasters alike are taking issue with the FCC's proposal to impair up to 20 percent of the spectrum that carriers will bid on. The FCC will impair the spectrum on an aggregated, weighted and nationwide basis.

 

"There is a striking consensus, cutting across all stakeholders, that the placement of TV stations in the 600 MHz LTE band will spread impairment throughout the national band plan, with impairments especially likely (and especially extensive) in the largest markets that are key to the success of the auction," AT&T noted in its comments. "The commenters broadly recognize that such impairments will reduce the quality, usefulness, and quantity of the auctioned spectrum."

This has always been one of the biggest problems.  That the places where the spectrum is most desired from providers, like Top 50 markets, will have significant impairments from legacy TV licensees who do not move.  Making everyone to bid for only one or two slots not near encumbered broadcast spectrum in each market.

 

It will still be good under the current rules in places like the rural West and Alaska.  But I even wonder with all the TV translator stations in the rural West if there is a problem even there.

 

It just feels like 600MHz gets farther and farther down the road.  Delay after delay.  Maybe I should get a job at the FCC working on the 600MHz plan?  Because at least there will be long term job security.  :)

    • 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.
