    Hehe never thought that I'd hear a "panel envy" term in my life What's interesting is these panels are installed along the elevated NYC subway stations, on the roof tops, so as you're waiting for the train to arrive, you're a few feet away from Ericsson's best lol Signal level -30dBm... I feel radiated

    This is a pretty awesome topic so I wanted to contribute some awesome stuff. These are the new Ericsson AIR Integrated Antennas with integrated radio tops. Notice no RRU. T-Mobile is exclusively deploying these as far as I know. They're dual mode 2x2 MIMO, Release 10 stuff. Snapped a few shots earlier today: Later I did my research and here is the official stuff:

    Oh that would be purely for testing purposes
  4. milan03
    I assume unlocked GSM/LTE devices with Band 4LTE would not attach in LTE only mode. I'm tempted to find used MetroPCS SIII lol.
  5. milan03
    I have DNA, it's only Band 13 unfortunately. The only Verizon device that is currently Band 4 capable is Galaxy Note 10.1 that just passed through FCC. It's not commercially available yet. That actually makes a lot of sense. On that note, would MetroPCS Band 4 LTE phones attach to Verizon's Band 4?
  6. milan03
    This is currently an annoyance, and it's a shame they didn't require OEMs to include Band 4 earlier. Would a MetroPCS LTE handset attach to Verizon's Band 4 LTE (once deployed) or they're using a different authentication method?

    2x1 MISO like all other current Cat 3 devices.

    Well in big metros like NYC I can see Verizon having proper backhaul as this is the market where I'm able to max out the LTE sector at 72mbps. On cell macros with 3+ sectors, I can't imagine them running less than 500mbps fiber feed in NYC. They can remotely dial up/down on demand. In some smaller markets it'll be interesting to see how will they handle the backhaul. T-Mobile is in a similar position. Sprint doesn't need massive backhaul for 2x5Mhz LTE at the moment but that'll change. I have no clue what's AT&T doing as they only care what investors think... It wouldn't surprise me if they keep being stingy lol.

    Brian from Anandtech did this preview of MSM8974 SoC with integrated LTE-A modem at CES. It's really running MDM9x25 IP stack http://www.anandtech.com/show/6634/qualcomm-demos-category-4-lte-150-mbps-running-on-snapdragon-800-msm8974
  10. milan03
    So the new QUALCOMM MDM9x25 baseband chipsets are LTE-Advanced. They are sampling and first UE should be popping out in a few months time. They'll be able to do carrier aggregation, they're Cat 4 chipsets capable of 150mbps on the downlink. But to achieve 150mbps, you need a carrier to deploy either 2x20Mhz slice in a given Release 8/9band, or to deploy Release 10 network and aggregate two 10Mhz bands. Only T-Mobile will have Release 10 network, and only Verizon can currently deploy 2x20Mhz in the AWS band that could achieve 150mbps speeds. Also keep in mind that a single 2x20Mhz slice will drain much less battery than aggregated 2x2x10Mhz carriers. Verizon announced during CES that this year they'll be deploying AWS as a separate carrier for capacity, and in 2014 they'll aggregate it with their existing 700c. Then 4x4 MIMO is clearly an issue on UE side, but also the base station has to be upgraded for higher order MIMO, which no one but T-Mobile even mentions in their presentations. Other features like HetNet, Relay, CoMP all require at least Rel 10 network side upgrades. Those features are not even available to deploy really. So it's fair to say that this year we will first see LTE-A capable Cat 4 UE, as soon as this or next quarter.

    Yup I agree with you, and in a perfect world they should. I just think they have to chose the absolute shortest way back to competing, and laser focus on it. That sadly means no love for rural areas in 2013...
  12. milan03
    I don't think any other carrier except Sprint has such a granular plan on deploying to almost all sites, nationwide. That alone is quite remarkable. The other three carriers are more about pops covered, and then in the future slowly adding density. Not sure if that's good or bad, as their PR teams are all over this method and certainly banking. T-Mobile is now focusing on metro's with the highest amount of pops, and not on coverage simply because this is their last chance to get in the game and compete with the top 3. They're bleeding customers badly. They would never be able to do anything spectacular on the coverage plan, as they still have quite a large amount of EDGE only areas, with no ETA on upgrades. Their two spectrum licenses are in the high frequency bands, they don't have that proper cell density outside of metros to do any damage with PCS and AWS. But one thing they can compete is the network performance and that's where their focus is clearly gonna be. 2x10 LTE then later 2x20, and now HD Voice in all markets. Their voice quality has always been beautiful sounding full rate, I am curious to check out AMR-WB.

    Clearwire is basically in limbo just like T-Mobile was during the AT&T merger months. They are waiting for the regulatory approval, and not sure if they should be deploying, on what scale, or just simply wait. Sadly, looking at their track record they'll most likely chill and wait for the approval.
  14. milan03
    Lol that's so true. Only metros and burbs are getting LTE though which is where the most pops are.
  15. milan03
    Yeah whatever they're doing, they're doing it right. They appear to be pretty serious about their deployment.
  16. milan03
    Yeah in NYC the experience is just about the same. T-Mobile's 1900 HSPA+21 is less loaded, it's running circles around AT&T's HSPA 14.4. But the coverage isn't 100%. Also, as they're refarming their PCS, they're upgrading cell sites, which are now Rel 10 with RRU. They're not moving users away from DC-HSPA+ on AWS, they're simply deploying to the remaining AWS blocks (for now) until the MetroPCS merger goes through and they start refarming MPCS AWS spectrum. So initially, T-Mobile LTE will be 2x10Mhz with some markets only 2x5Mhz. After the merger in 2014-15 timeframe it's mostly gonna be 2x20Mhz.
  17. milan03
    Not sure what exactly do you mean by this, but T-Mobile is suppose to cover 100+ mil pops by mid year and 200Mil by the end of 2013. Did you mean Timeline for the first market to launch? If not how could they possibly share the same timeline? Rumors are that T-Mobile might be soft launching Vegas during CES.
  18. milan03
    Ok, I think I may have chicken nightmares tonight lol.
  19. milan03
    Haha no I haven't heard of that one, but we went to Sunflower Drive-in and the scenery was the same... It was a vegetarian joint, famous for their nut burger. Chicken roaming around... That whole Sac area is such a beautiful place to live. My gf's folks are from there.
  20. milan03
    Lol I knew it! It was totally obvious coming from NYC where all resource blocks and backhaul were in place. I was also testing in Fair Oaks and Carmichael and there was 30mbps all day not a bit over.
  21. milan03
    This is very true. Back in summer '11 in Sacramento I couldn't pull more than 30mbps anywhere which actually matched local Comcast cable offerings lol. Always wondered if they're leasing their backhaul from local CableCo's over there. In large and dense markets like NYC their sites are mostly fed with massive fiber backhaul though.
  22. milan03
    Although it did come down (I can't get 70+mbps anymore), it's still peaking at about 60mbps. But the average has been drastically reduced as you know already. It's not 20+mbps it's more 5-12mbps. In some areas of NYC it completely stalls during the peak hours. It's getting bad. That AWS has to happen this year, otherwise we'll be seeing lots of pissed of Verizon customers. And those are massive 40Mhz slices so that's a lot of capacity. This could be a great opportunity for Sprint to deploy sooner rather than later and take those customers with Unlimited Data and other affordable incentives.
  23. milan03
    Those speeds are perfectly within Verizon's range considering that they advertise LTE speeds as 5-12mbps down and 2-5mbps up. The latest I've heard from them is that by this summer their 700Mhz LTE is gonna overlay their entire EVDO footprint, at which point they'll be deploying AWS for capacity. Now, that's a pretty vague statement as we have no idea if they'll be staying at Release 8 and just deploy a second carrier for capacity, or if they'll be upgrading their cell sites to Release 10 in the process. It would make sense to start upgrading to Rel 10 as they could use HetNet and other LTE-A tools down the road.
  24. milan03
    I like the proposal, but lets not forget about PCS constrained T-Mobile markets with the huge amount of POPs like NYC. I'm pretty sure T-Mobile would much rather agree to swap than sell, unless its forced to.
  25. milan03
    Don't forget that Swedish provider Telia has 2.6Ghz FDD LTE network up and running successfully since 2009. They've been running 2x20Mhz for a while there.
