  1. Network Vision/LTE - New York City Market

    What's hard to believe? Nokia removed the Samsung Clear eNB and replaced it with their own Nokia eNB while adding additional capacity at minimal cost. It's something seen in several markets that has been happening very slowly." MMR's (massive mimo radios) are not ready to be deployed for prime time at this time.
  2. Network Vision/LTE - New York City Market

    Not necessarily. Nokia mini macros and most small cells are all in one eNB that contain the BTS and RRUs in one compact unit. All it means is that there is an added mini macro to an existing site adding another additional 40 MHz of capacity based on the GCI ending. Sent from my Pixel using Tapatalk
  3. Network Vision/LTE - New York City Market

    Not a mistake. It means what it means. High capacity mini macro setup. Sent from my Pixel using Tapatalk
  4. It is not for public release, yet. If you've seen their network slides you'll see it go from macro, mini macro, airpole, magic box, and femto. Only the MB and Femtos are customer accessible. Sent from my Pixel using Tapatalk
  5. Yeah that's the airspan airstrand which is a strand mounted small cell using Docsis for backhaul.. The other variant would be the Airpole which is a low powered standalone small cell you can put on a pole on the side of a house. Sent from my Pixel using Tapatalk
  6. Official Magic Box discussion thread

    Contact the MB support line. Could be the Donor tower needs a software toggle to support MBs.
  7. Yeah. Just put it into another macro site and doing a bit of work bringing it up. Again massive MIMO units will be in high density urban areas where it's impact will be felt the most. It's numbers will not make a dent compared to 8t8r and the mini macro / small cell units which would provide the vast majority of coverage and capacity. Sent from my Pixel using Tapatalk
  8. Mini macros are the same exact units used in stand alone small cell deployments and on macro sites. They're cheap, they require minimal work to configure, and are widely available compared to macro equipment and have the factor of being reusable if not needed anymore on macro sites. The vast majority of macro sites outside of rural or suburban areas will have 8t8r units with a few hundred in urban high density areas having massive mimo units. Sent from my Pixel using Tapatalk
  9. sprint network 2018 predictions

    Yep. It'll be sprints own spectrum at the end with the CDMA 1x800 carrier pushed right up next to the LTE 800 carrier while Solinco does its own thing. Sent from my Pixel using Tapatalk
  10. Tim YuSprint 4G Rollout UpdatesJanuary 12, 2018 - 5:30 PM PST "New year, new me. Am I right?" ~ signed Samsung Samsung has decided that the beginning of the new year is a great time to change. Samsung has decided its newest flagship Galaxy S9 and S9 Plus devices must meet with the FCC OET for certification far earlier than usual. With ever watchful and prying eyes, S4GRU staff discovered the twin filings for two devices with FCC IDs of A3LSMG960U and A3LSMG965U which follows the previous Samsung numeration of the Galaxy S8 / 8+ (950u/955u) and Galaxy S7 (930u/935u) respectively. In addition, previous leaks for purported international Galaxy S9 variant have captured the ID of 960F and 965F respectively. To keep this short and simple, the Galaxy S9, to date, is the most technologically powerful device we've seen at least for Sprint and possibly other entities and the following technical specifications should demonstrate why. CDMA BC: 0 / 1 / 10 GSM: 850 / 1900 WCDMA Bands: 2, 4 , 5 LTE Band: 2, 4, 5, 7, 12, 13, 14, 17, 25 , 26 , 29, 30, 38, 41, 66, 71 Downlink Carrier Aggregation (DL CA) 5xB41 (up to 5 B41 carriers aggregated) B25+41CA (up to 2 B41 carriers - 3 total carriers aggregated ) B26+41CA (up to 2 B41 carriers - 3 total carriers aggregated ) B25+26CA (up to 2 B25 carriers - 3 total carriers aggregated ) Uplink Carrier Aggregation (UL CA) 2xB41 256 / 64 QAM Downlink/ Uplink HPUE CAT 18 Modem 4x4 MIMO B2, 4, 25, 30 , 41, 66 12 spatial streams Holy bonanza! This phone supports up to 100 MHz of LTE spectrum being aggregated together from 5 individual Band 41 carriers! To add to that, it also supports FDD and TDD LTE carrier aggregation by utilizing Band 25 1900 MHz or Band 26 800 MHz as the primary component carrier which would contribute to downlink and uplink while Band 41 is aggregated to it would be downlink only secondary component carriers. Remember the saying of having B25 or B26 uplink with Band 41 downlink, anybody? Plus there is expansion of FDD carrier aggregation to that of between Band 25 and Band 26. This will help a ton in areas where Band 41 and its oodles of capacity does not reach. As the recent CDMA refarming nationwide on PCS spectrum has allowed Sprint to fire up an additional Band 25 carrier, this means in many Sprint markets there currently exists two Band 25 carriers in addition to a Band 26 carrier. This additional carrier is not forgotten and can now be used alongside the other Band 25 and Band 26 carrier for carrier aggregation. Last but not least, this phone is "Gigabit Class" by having up to 12 spacial streams means that 4x4 MIMO can be used for 3 separate B41 carriers when aggregated together instead of 2 in the previous generation which supports only 10 spacial streams. Though it was a moot point as the entire generation of Samsung flagships from this past year did not support 4x4 MIMO on Band 41, until now! A phone this size should not be able to pack so many technologies...but yet it does! A splendid phone and surely a must have for the S4GRU and other tech adept users!
  11. Nice. That's the 4th carriers based on GCI indicators of 0C and 0E but the 40270 with GCI of 08 is a bit weird. Usually 00-02 is 1st, 03-05 is 2nd, and 06-08 is third for an 8t8r three carrier chain. Interesting.. Try and grab more of the GCIs if you can. Sent from my Pixel using Tapatalk
  12. I mean if people want "coverage" smacking down a B26 mini Mac and an omnidirectional antenna gives you that. *totally not because we found such a site in a rural previously no native coverage area* Sent from my Pixel using Tapatalk
  13. What are the GCI of the cells? If it's 4/5/6 then it'll be sequential 0C/0D/0E and onwards. Small cells (Airspan) will be 01 and then 04(?). Sent from my Pixel using Tapatalk
  14. Mostly done. Triband (750, 1900,2500) sites will be getting deployed once the cleanup from the hurricane mess is completed.
