    AT&T band 5 LTE 850 makes its first appearance

    in General Topics

    Posted

    Where did you read that? AWS spectrum is always paired with 1700 and 2100 MHz spectrum. Whatever table you are looking at is wrong or the 2100 MHz is assumed. The uplink is 1700 and downlink is 2100 MHz. In terms of video streaming on youtube/Netflix and web browsing on the go when you are out and about the downlink is what really matters. Think of it like your home ISP, you just care about the downlink speeds and not the uplink speeds.

     

    So if you think about it from a marketing perspective the perception that "lower frequency" equals "superior service" due to better building penetration characteristics. Just look at the marketing from Verizon and ATT, they have said that their LTE is superior than Sprint because they deploy LTE on 700 MHz which is low band frequency and penetrates buildings better.

     

    So for Tmobile advertising LTE at 1700 MHz is not technically wrong since the uplink part of LTE will be deployed on 1700 MHz but we know that the downlink is what really matters and that is deployed at 2100 MHz. It sounds better to advertise LTE at 1700 MHz than at 2100 MHz because lower is better. Heck they can say that Tmobile LTE beats Sprint LTE since Sprint LTE deploys at 1900 MHz.

     

    But isn't it the case that you have to have a good uplink signal to have a good downlink? It's my understanding that it's a weakest link type situation - that is to say that AWS will effectively have the performance characteristics of a signal that had both the uplink and downlink on 2100mhz spectrum. Maybe AJ or Robert can chime in.

    T-Mobile uses their 1700/2100 Mhz for upload/download combination.

    Do they do that because they are required to, or because they want to?

     

    Maybe a 700/850Mhz combination would be better paired?

     

    T-Mobile doesn't have a choice, nor do AT&T or Verizon or any of the smaller carriers on AWS  - that's just how the AWS spectrum was paired by the FCC

    AT&T uses a combined panel for all their different bands for use in limited space stealth sites and flagpoles. Sprint could do the same. They just usually support less carriers. But that way they can use all three bands and still upgrade the site.

    Are triband panels that support all three NV frequencies currently available?

    Shopping for an Spectrum Analyzer - RF Explorer

    in General Topics

    Posted

    I was just about to pull the trigger and buy one, then my router went down. So I bought a really powerful AC 5GHz wifi router that should cover my entire house and front yard/gazebo. So I will have to wait on the spectrum analyzer until next month.

    Not to derail the thread, but what kind of router did you get? I have had trouble finding a really good power and fast 802.11n router, but haven't tried AC

    Wow they're moving quick.

     

    System for Mobile Communications, or GSM, and Enhanced Data rates for GSM Evolution, or EDGE, will be on market-by-market basis. Service on the networks will be fully discontinued by about Jan. 1, 2017.

     

    http://m.us.wsj.com/articles/a/SB10000872396390443687504577567313211264588?mg=reno64-wsj

     

    Not that quick really - EDGE will have been out there for what, 15 years by that shutdown date, and EDGE is about as 1x for data. I assume GSM will go with it. Since they are redoing their network with LTE and HSPA+ and WCDMA/HSPA+ carries voice, GSM is pretty useless at this point.

     

    I also seem to recall T-Mobile saying that, wherever possible, they want to totally shut down GSM/EDGE and be totally HSPA+ and LTE.

    Sprint is apparently going to add another 15,000 to 18,000 sites for TD-LTE!

     

    Sprint's total cell site count will increase to somewhere between 50,000 and 60,000 sites, more than offsetting disconnects of old Clearwire sites.

    15,000 to 18,000 additional sites... that's a damn significant increase from the approx... what is it, 32,000 sites sites Sprint has now? I would assume they will be full build sites, and, if that's the case, this could be part of Son's plan to increase Sprint's coverage area and truly compete with Verizon and AT&T. That would be pretty awesome.

    But the thing is, it is.... T-mobile is just blowing sprint out of the water when it comes to rolling out their LTE network. Sent from my Coconut Wireless HTC One

    They are rolling out quickly in some areas, but their LTE and 3G are too spotty to be valuable to me. It's unacceptable to me that at least fifty percent of the time in some metro areas I can be on EDGE. They're not comparable roll outs.

    How is NV 3G?

    in Network, Network Vision/LTE Deployment

    Posted

    Besides the 800 mhz rollout, would network vision upgrades increase the signal strength dramatically? I know my area isn't broadcasting 800 mhz, but in my in house I normally got about 3 bars of service, but all this weekend my phone has been a solid 6 bars. It seems my wimax reception has been steadily declining, though.

    Others may be able to speak to this better than I, but my understanding is that NV does result in some marginal improvements in 1900mhz coverage due to the new panels and use of RRUs.

    Yeah, those are some of the few markets that have actually broadcast their locations somewhat accurately. In the Nebraska market, Kansas market, Colorado market, and Missouri market, the locations that sites broadcast, even NV sites, are no where close to correct :(

    Have we determined if this is an OEM issue? That is to say, is one of the OEMs updating the broadcast coordinates to be correct and the other two aren't? Or two are and one isn't?

    Sprint to Shut Down Wimax by End of 2015 (Was Wimax network shut-off date?)

    in WiMax

    Posted

    Where we are there is a home brew cable service and a telephone switching board,,, so cable is out and so is DSL. Clear wire was my best "unlimited" choice. Everyone else caps the data.

     

    What to do,,,, what to do,,,,,,,,,,,,,,,,,

    If you're lucky, maybe there will end up bring a data only mvno like freedom Pop or net zero that will offer a plan with high caps. You probably won't get another unlimited provider, but with a bit of luck you might get an acceptable alternative.

    How does 4G coverage compare to Evdo / 1x

    in Network, Network Vision/LTE Deployment

    Posted

    so is LTE in rural areas like mine where cell spacing is in the 5-10 mile range going to be lilly pad style or what?

     

    It depends on how the towers are engineered and optimized. I don't know what the likelihood of blanketing an area with LTE 1900 coverage is with that cell spacing, but it might be possible with tall enough towers and absolutely no downtilt. People like AJ and Robert would be able to give you a better response.

    I am hoping it is just my EVOLTE being really really bad, but I lose the LTE when I get just about 2 miles from the live site in Myrtle Beach... I was able to map a solid 2 mile circle around it -- then nothing (it drops off around -125).  So basically with this EVO I will have little two mile radius islands of LTE when the light up more towers (I am going to eventually get my wife's GS4 out there and play with it to see how far I can make it away from the tower)...

     

    We know the EVO LTE sucks in terms of reception and LTE performance in general, but I don't know that two miles is necessarily an unusually small coverage area for a cell, depending on downtilt and the topography of the area.

    So how realistic is the goal of getting all currently active NV sites updated to LTE 800 by the end of the year? I was wondering if possibly why we haven't seen as many 1xA 800 accepts as we expected after the Nextel shutdown is that they're waiting so they can install 1xA and LTE 800 together from here on out. Is all the equipment, ie carrier cards and all that already available and stocked?
