  1. That’s actually a perfect comparison — thanks!
  2. Do you have the dimensions of this antenna by any chance? Or maybe a picture of it next to NV/next-gen equipment?
  3. Don’t forget the improved coverage and propagation with lowband spectrum.

    Network Vision/LTE - San Diego Market

    Oh, I see. I really don’t know what the holdup is here with the equipment now capable of 15 MHz FDD L1900.

    My guess would be the new IMS for VoLTE.

    Isn’t this non contiguous though? It looks like the C3 carrier aggregated with the C5+G carrier...
  8. Hey guys, Sprint’s coverage map received a big update today. USCC roaming is now extended! Additionally the map is now full screen. Native coverage now appears to be more accurate (at least in my market) as well as detailed. Take a peek and see for yourselves!
  9. There are tons of ways—looking at the physical equipment, measuring RSRP/RSCP/RSSI levels near the site, trying to connect to the different sectors of a site as you move around it, online tools that provide this sort of data, etc.
  10. Imagine how much better Sprint will be once they’ve got 800 MHz up and running. 15x15 L1900 as well.
  11. Getting a picture of the RRUs would help…
  12. Nice! Looks like it’s finally happening.
  13. I don’t know… We’ve already seen real world demonstrations of massive MIMO on 3500 MHz marching the range and propagation of 1800 MHz (at 2x2 MIMO); I can only imagine how Sprint’s 2500 MHz NR will look with 64x64 MIMO... In Seattle (which was PCS/BRS only until a few months ago), if 2500 MHz NR coverage could match L1900 coverage today, Sprint would be the undisputed #1 carrier.
  14. It is probably the power company building out their own network. What company/market is it?

    I like that ping.
  16. Samsung equipment has already received the software upgrade for 4x4 MIMO, 256QAM and 15x15 L1900 although I don’t *think* we’ve heard anything regarding Alcatel Lucent...
  17. I don’t know...there are only two jumpers to each antenna which makes me think it’s probably not a high-order MIMO deployment... It could possibly be a regional carrier...
  18. It seems I’ve come home to another pleasant surprise — a new site with hexadecaport antennas located on Microsoft building 43. I can’t connect to it yet, but it’ll definitely improve coverage and capacity in the surrounding areas when it comes online.
  19. Just returned to Seattle to a pleasant surprise — full LTE throughout SeaTac airport! Never thought this day would come. Service was -102 or worse on L1900 or L2500 before. Now signal on L1900 doesn’t drop below -90.
  20. According to my local Sprint engineer, the new antennas have inferior spread compared to the old ones. This translates to coverage loss in some scenarios but not all. I’ve run into problems (that previously didn’t exist) mostly in the null zones between sectors and in hilly areas where my elevation is considerably different from that of the RAT center.
