    I can see how this merger would benefit "SprinT-Mobile" on the corporate level. They'd have similar subs base as the big two, by far largest spectrum portfolio, more revenue, etc. But I can't see how's this going to benefit us consumers short to mid term? Sprint is in the middle of lengthy NV process deploying 800Mhz voice and LTE to every single cell site, ripping the old infrastructure and replacing it with the latest and greatest, upgrading the backhaul. They're serious about fortifying and expanding the existing CDMA footprint, and of course supporting the existing CDMA subs base for years to come. T-Mobile is putting finishing touches on their network modernization, migrating MetroPCS subs to GSM/WCDMA/LTE handsets, will sunset their CDMA network and repurpose the spectrum by mid 2015. They're also disruptive with their plans and aggressive network strategy, causing other wireless providers to react, driving the overall prices down for all of us. If they merge, "SprinT-Mobile" may benefit from shared collocated site bills in some instances, but two network have a very different coverage and strategic site footprint at least in my area, which isn't gonna change overnight as that would be a nightmare for engineers. Two networks are fully matured, finely tuned, and any kind of shift in cell site placement especially in topographically challenged urban areas can cause a ton of headache. It's already been mentioned that they'll be running two different technologies for a while, which is redundant. Over time they could eventually all meet at the VoLTE, and consolidate, but near term that's not happening. By eliminating a Tier-1 provider, consumers definitely aren't benefitting in terms of user experience short-to-mid term, and since Legere is most likely going to be demoted we may not have that consumer friendly disruption in the industry, driving the prices down causing others to react.

    Interesting BusinessWeek article popped up today http://www.businessweek.com/news/2013-12-13/verizon-said-to-be-near-agreement-to-sell-airwaves-to-t-mobile

    That actually make pretty good sense, assuming those markets still have sufficient amount of left over AWS and PCS so that voice remains uninterrupted and HSPA/LTE service could be deployed. I'd much rather see T-Mobile acquiring 700Mhz A from smaller smaller providers or spectrum holders in those secondary markets for rural deployment, but oh well.

    I don't see how swap could be a solution for T-Mobile since their AWS is all deployed. I can only think of AWS rich market like Dallas where they could shut down their A block and divest to Verizon, but they'll still pay a lot of money for 700Mhz A so not sure if that'd make much sense...

    Which makes us wonder if it's the backhaul or software rate limiting us to peak at 80Mbps on a completely unloaded Verizon's 20Mhz FDD layer at 4am on any given day. Should be much closer to 150Mbps with Cat 4 UE.
  6. milan03
    Hey I've found this exact OFDMA range a few months ago! Awesome!
  7. milan03
    No worries, once your Nexus 5 arrives, you'll see how easy it is I'm totally convinced that you could do it!
  8. milan03
    Thanks for breaking the price down for us! That totally makes me wonder what's the reason behind their ~80Mbps rate limit on unloaded cells, day or night, city wide. Could be rate limiting, but why would they do that? For T-Mobile it makes much more sense as their backhaul is still 50Mbps in many markets, which used to be alright in their 5Mhz markets, def not cool in 10Mhz FDD LTE markets.

    Was referring to two live FDD airlinks they have to support per sector. 10Mhz of Band 13, and 20Mhz of AWS.
  10. milan03
    Carriers like to initially under provision their backhaul service until they absolutely have to pay for more bandwidth. Verizon has fiber to pretty much all of their cell sites in NYC, but they're definitely not paying extra $$$ to support the entire 150Mbps + 73.6Mbps per sector, yet. Their 10Mhz Band 13 is constantly loaded, but Band 4 is consistently above their advertised 5-12Mbps, so I guess they're saving money... T-Mobile is doing pretty much the same. They just went from 5Mhz FDD LTE to 10Mhz FDD LTE in NYC, and peak speeds went from 35Mbps to only ~40Mbps on an unloaded sector. The upload has doubled to about ~20Mbps. The good news is that it's all scalable and only requires remote provisioning if the equipment is in place. It is an extra expense for wireless operators, but with sufficient backhaul service they're effectively increasing spectral efficiency at their cells by utilizing extra capacity, and potentially shortening data session time at the UE.

    Got it. So the real benefit of testing UE for wider than 5Mhz on B25 is future proofing since it will be able to connect to wider channels anywhere between A-F on the PCS, G block stays at 5Mhz, correct?
  12. milan03
    So hypothetically speaking, if Sprint had C block PCS spectrum refarmed for LTE in certain markets, would 20Mhz on B25 capable devices ever attach to anything wider than 5Mhz? My gut instinct says no, but would like to hear some opinions.
  13. milan03
    Ah so it scans for the adjacent PCS C block? The reason I'm asking is because G block is only a 5Mhz FDD spectrum slice. Can't be larger than 5Mhz itself, unless the device dips down into the C block which is really B2.
  14. milan03
    Not sure what would be the point/benefit of UE covering wider than 5Mhz on B25. Can anyone explain? -Thanks.
  15. milan03
    What's the center frequency? I've been seeing two major 20Mhz spans here in NYC, one in the 2500Mhz range, and other in the high 2600Mhz.
  16. milan03
    That's an interesting point, because on Nexus 5, EARCFN could be carved out of the DEBUG LTE Engineering menu which I find very useful. Send me a beta, and I'll test band indicator on my Nexus 5, gladly!!
  17. milan03
    Can you at least maintain a consistent B41 connection when in "LTE Only" mode and idling, or the same connectivity issues persist?
  18. milan03
    I'm pretty sure it's this
  19. milan03
    Did you say without the SIM?!
  20. milan03
    Exactly, B4 only VZW device would be perfect for testing. But your example goes to show that N5 is fully capable of working on Verizon's CDMA network. I guess one could technically force B4 Only on Verizon's Galaxy phones as well
  21. milan03
    Yeah I'm not successfully attaching to Verizon at all. No bars, although sometimes i'd briefly see "Verizon Wireless" in PhoneInfo. Even my phone number is unavailable. I emailed my Verizon rep and asked him to add the IMEI to my account. Told him it's a Galaxy Nexus lol. Doubt it'll actually happen, but lets see ...
  22. milan03
    What's interesting is that when active Verizon SIM is inserted in Nexus 5, you can only toggle LTE Only, and 3GPP technologies. It will not allow toggling 3GPP2 at all. But then again, I'm not successfully attaching to Verizon which could explain this behavior carrying over previous (T-Mobile) settings. It's extremely frustrating not to be able to utilize this great Cat 4 UE on Verizon's 20Mhz B4 that's active here.
  23. milan03
    Just as AJ suggested, there are absolutely no 4x4 or 8x8 MIMO commercial user setups. Not only the form factor, but power consumption is the biggest challenge for higher order MIMO in the UE. NSN Flexi 10 supports 8-pipe radio, each port capable of 2x2 MIMO and upgradable to 4x4 and 8x8 down the road. It just doesn't make any sense for carriers to deploy 4x4 or higher at this time.

    Verizon seems to be taking AWS capacity pretty serious in NYC, as their B13 network is getting to the point of being unusable. They're installing AWS capable DAS systems all over Times Square, Columbus Circle, Bryant Park, but today I also discovered those same antennas on the East Side along 3rd Avenue between 50th Street and Queensboro Bridge. Successfully connecting to B4, but their backhaul seems to be a gating factor at this point. My Cat 3 UE seems to be peaking at ~80Mbps, which indicates that backhaul may have to be remotely adjusted once the network is officially launched to support 150Mbps at the cell. With a very few UE being able to attach to their B4, I guess provisioning and paying for more backhaul capacity isn't cost effective solution for Verizon at this point in time.
  25. milan03
    They'll totally be able to aggregate 10Mhz FDD LTE in 700Mhz B17, with 5Mhz FDD LTE in PCS B2 in NYC. I think that'll come with Release 11.
