    Let me reiterate my disbelief that T-Mobile had 51,000 macro sites before the merger. They were always 1-2,000 sites behind Sprint. I am not convinced. I will find the truth even if it kills me or I have to use the wayback machine. The way that the confusion may arise is that T-Mobile might have 37,000 HSPA+ sites and about 14,000 GSM sites, but they are colocated. They might even have legacy basestations. They might have 51,000 leases. That's exclusive of Metro. It's not just me that has doubts. AJ, our local guru, is also incredulous and we have been around for awhile.

    Well, no matter whether you unity or non-unity frequency reuse, you will have reduced performance at cell edge. All thse methods are used so that your throughput incereases vs not having them.
  3. bigsnake49
    There are lot of techniques to improve cell edge performance. Interference cancellation, subcarrier coordination between sites, etc. I don't remember how many of these LTE employs.
  4. bigsnake49
    Yes, non-unity frequency reuse allows you to not have to worry about cell edge performance. You basically don't have to tune the network if you're using 10MHz sector channels and 30MHz per site.

    No, Dish wanted Sprint to host their spectrum but wanted it done under their terms, which is they would repay Sprint with capacity on Dish's hosted spectrum. Sprint wanted to get paid up front and then have an option to purchase capacity.
  6. bigsnake49
    Well, if they can get some money out of them, who cares? When you don't need the spectrum and you're paying good money for those leases, you might swallow those feelings.
  7. bigsnake49
    Neither. I guess Dish can scoop up USCC, Leap and CSpire as well as some real small rural carriers and try to piece a network together. They can use white spaces spectrum to provide fixed broadband to rural and exurban customers, although I don't see why Sprint won't sell them spectrum in the EBS band in those same rural and exurban areas.

    So you're slightly FDD dyslexic .
  9. bigsnake49
    Yeah you have the AWS links reversed.
  10. bigsnake49
    I personally think that they would have absolutely no problems gobbling up the spectrum. They might be the only ones in the running.
  11. bigsnake49
    That's probably when I expect Sprint to start refarming their PCS A-F holdings.
  12. bigsnake49
    Yes, absolutely, once they can move pretty much all the data from EVDO to LTE. It is not as pressing of a matter now since they can deploy LTE on 800MHz and 2500MHz, but very soon Sprint's PCS A-F bands will only hosting 1 1xAdvanced and one EVDO channel for legacy reasons. Once voice gets moved to VOLTE and M2M contracts expire, then of course they will totally devote all PCS holdings to LTE.

    I don't know what to tell you, but I quoted directly from the FCC document. Maybe there is a different spec for MiFi's. So those can be assigned to block G and the actual handsets can be on either block.

    I need to see a historical accounting of the number of T-Mobile sites. There's some creative accounting going on. Is T-Mobile counting in-building repeaters as sites? Because nobody else does. For example at couple of my consulting sites, Verizon, AT&T ans Sprint all have repeaters in each floor of the building. That does not count as a site. May they're counting DAS as sites?

    "Notably, in performing the testing and reaching the recommendations, the tests all were conducted assuming an LTE mobile device operating at the maximum power level indicated in the 3GPP LTE specifications—23 dBm." It seems to be 3GPP compliant, a mobile terminal is limited to 23dbm

    "It expects the two vendors to install equipment in all the 37,000 cell towers in its network for its upgrade to a faster-speed wireless data service." http://www.huffingtonpost.com/2012/05/08/t-mobile-network-upgrade_n_1498501.html

    Kevin Fitchard came up with that number and has been quotes by other websites giving credit to Gigaom. Everybody else quotes 37,000 which lines up with what I remember. The agreement with SBA followed a deal announced in late July with Crown Castle extending current leases on 7,300 Crown Castle sites for 10 years and granting T-Mobile rights to upgrade certain towers to go along with the carrier’s network upgrade plan. Crown Castle noted the agreement will result in an increase in site revenue beginning during the current third quarter. T-Mobile USA currently runs its network across some 37,000 cell sites. http://www.rcrwireless.com/article/20120917/tower/sba-signs-tower-extension-t-mobile-usa/

    There's a lot of confusion, but pre-merger T-Mobile had approximately 37,000 sites. MetroPCS had 11,000 plus 6000 DAS. so together they have 49,000. Now from the articles it seems that they will deactivate 10,000 of the 11,000 macro sites Leaving them wih 38,000 macro sites plus 6,000 DAS.

    T-Mobile CTO Neville Ray continues his rounds of discussion in New Orleans as CTIA continues, this time with a comment to Reuters on T-Mobile’s purported tower sale. T-Mobile has previously said it would explore the sale of 7,000 of 37,000 wireless towers to gain some financial independence from parent Deutsche Telekom. http://www.tmonews.com/2012/05/t-mobile-cto-neville-ray-says-tower-sale-could-take-months/

    I thought EIRP is limited to 300mW, which is OK unless you're talking about real rural, but then something tells me that the inteference from other mobiles will be non-existent. The only thing that had me slightly concerned was the OOBE emmisions on the high end of the uplink (1915-1920MHz). But there is the 10MHz UPCS band between 1920-1930MHz which means the filters don't have to be as sharp as if there was no buffer. Plus the filters keep getting better.
  21. bigsnake49
    My concerns about lower power levels are pretty much alleviated. Since the H band will not come into effect until 2015 at the earliest due to lead time for H block devices, the OOBE on the device side with respect to PCS downlink is not onerous.

    "While MetroPCS's CDMA network will be shut down by the end of 2015 - T-Mobile is turning off 10,000 of MetroPCS's 11,000 cell sites - the brand will continue, and T-Mobile will migrate customers to less expensive and more capable GSM/HSPA+ phones, Legere said...." http://www.pcmag.com/article2/0,2817,2412948,00.asp
  23. bigsnake49
    They had 35-36,000 of their own sites the rest of the 51,000 are MetroPCS sites. They don't need to upgrade the MetroPCS sites since those will be shutdown.
  24. bigsnake49
    In single antenna situations you are right. However higher frequencies can accomodate higher order MIMO that lower frequencies. 4x4 MIMO might not be possible at 700MHz but it is definitely possible at 2.5Ghz. Actually 8x4 is possible at 2.5GHz.

    Thanks, AJ. You're a true friend .
