  1. 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!
  2. For all things magic box.
  3. 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.
  4. 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
  5. 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
  6. 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
  7. 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
  8. Official Magic Box discussion thread

    Contact the MB support line. Could be the Donor tower needs a software toggle to support MBs.
  9. Hello everyone! It is the belief of myself and of the staff that it is time to reopen a new T-mobile LTE and Network discussion thread due to the implementation of "network prioritization" that tmobile is doing to its subscribers. As Sprint has similar language in its TOS, we believe that it is worthy of being discussed here as Sprint may do something similar on a site by site basis. This thread will be strictly for discussing T-mobiles LTE network and technologies and not about personalities, their followers, and etc etc which may be better suited for S4GRUs sister site for T-mobile T4GRU. As a result this thread will be heavily moderated to stay on topic but I view the S4GRU member base very favorably and trust that we won't have much problems here.
  10. 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
  11. 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
  12. 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
  13. 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
  14. 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
  15. 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
  16. Mostly done. Triband (750, 1900,2500) sites will be getting deployed once the cleanup from the hurricane mess is completed.
  17. I mean Verizon is deploying so called "5G" via higher order MIMO (4x4 MIMO / massive mimo + CA on all bands) & newer better performing antennas in addition to split sectors here. I doubt any carrier is ready to deploy NR anytime soon as most of it is appears to be backward compatible as software enhancement to a lot of existing equipment in addition to not being finished in terms of what will be in the final revision. If anything, I imagine whatever ATT does will mirror that of verizon which makes sense considering both have been undergoing another full site revision to 4x4 MIMO via new radios and antennas. ATT also has the additional plus of deploying a new 10x10 700 MHz Band 14 network layer for Firstnet and their own usage which makes usage of HPUE and is greenfield spectrum.
  18. LG G6 to be Sprint's first HPUE-capable device

    Maybe Best buy $5/ month if it's still going on... Sent from my Pixel using Tapatalk
  19. [PSA] Generation "3" Magic Box has arrived!

    You power cycle it by unplugging the power cord.
  20. Tim YuSprint 4G Rollout UpdatesDecember 11, 2017 - 9:30 PM PST Recently, individuals who ordered Magic Boxes noticed a change in the product code of the unit to AU544 from AU545. It is now confirmed that the product code change is due to the release of the 3rd generation Magic Box. They are now being shipped! The new revision is in essence a GEN2 optimized with a high quality LCD touchscreen display like that of the 1st Generation AU540. In addition, an external battery pack with an adapter to hook onto the Magic Box is now provided. It can be lugged around for testing purposes instead of internal batteries. In addition, the touch power on button of the GEN2 has been removed with power on sequence done by plugging in power to the unit via a battery pack with an adapter or via the AC power brick. Performance wise, the GEN 3 is identical to the GEN 2 in that they still utilize the Airspan Airunity 545 small cell eNB and a Ninja LTE Relay module. The product designation change from 545 to 544 is primarily due to a change in the WiFi module to a different Qualcomm WiFi module. But for what matters to Sprint users, the LTE B41 performance impact as noted from GEN 1 and subsequently the GEN 2 are identical. GEN 2 users will not be left behind in performance wise. Previous generation device owners will not be missing out on much! For those that are getting the Magic Box for the first time, welcome to the party!

  21. I followed that exact guide and got mine flashed successfully. What changed since then was Asus (and other manufacturers) released new firmware that prevented firmware downgrades past a certain point due to abuses in transmit powers being adjusted and etc. So i would flash something before the 378 range first. I've relegated my flashed AC66 running Merlin 380 version to my relatives place as a primary AIO router for their 30 / 30 fiber connection. It had a few connectivity issues initially but a couple of complete resets has made it stable. I had to mess with my friends Sprint AC66 back in september since its IPSEC "prioritization" would mess with the Airave 3 / S1000 femto cell IPSEC tunnel back to Sprints network (~300 kbps limit up / down). I would not be surprised if they'll drop the router soon enough too as it's redundant with the Airave 3 / S1000 being able to offer AC WiFi + LTE &/or CDMA without the ipsec tunnel conflict.
  22. You're probably seeing just different sites using different contiguous carriers. It's the same thing in SLC. Part of the metro uses B41H while other parts of it uses B41L. I have several sites here that operate B41L while the vast majority operates B41H. Sent from my Pixel using Tapatalk
  23. Get rid of the old non updated firmware and load up the standard Asus or Asus Merlin.
  24. What's in the Box? Oh, oh, oh, it's Magic.

    Tim Yu Sprint 4G Rollout Updates May 19, 2017 - 8:30 AM PDT The Sprint Magic Box was announced on Sprint's quarterly earning call earlier this month, and was heralded as the first truly all wireless small cell in the industry. So what is this mystical beast that is purported to increase coverage by up to 30,000 square feet, amplifies data speeds, and "boosts" your data signal? This is the 1st Generation Sprint Magic Box In more technical terms, the Magic Box is an Airspan product under their Airunity line. The black colored model that exists in the wild, and which I procured contains the Airspan Airunity 540 small cell eNB. Whereas the white colored Magic Box advertised by Sprint is a newer model that contains the Airspan Airunity 545 small cell eNB. The primarily difference is that the unreleased white Magic Box is able to broadcast at twice the transmit power compared to the black model which results in substantially increased coverage area in addition to the LTE UE Relay Module having HPUE capability. These are all wireless small cells as there is no requirement of a wired backhaul solution like traditional Femto cells like the pending Sprint Airave 3 LTE, Commscope S1000, or the T-mobile LTE Cellspot. Instead, the Magic Box (MB) utilizes a technology called LTE UE Relay that is integrated into the overall package. The Magic Box contains an Airunity LTE B41 2500 MHz small cell and a LTE UE Relay device called the ninja module whose only job is to establish a data link to a macro eNB LTE 1900 or 2500 MHz signal and then feed a data connection to the Airunity small cell. For more on LTE UE Relay: see here Once the Relay link is connected and data flows to the Airunity eNB, a new LTE 2500 MHz signal is then created and broadcasted from the unit. This signal is unique to the Magic Box and is available to use by any compatible Sprint device that can access the LTE Plus (2500 MHz LTE B41) network. Unlike a repeater setup, the Magic Box does not simply take an existing signal and amplify it and all the accompanying noise and interference. This is a brand new and very clean LTE signal being broadcasted. The following screenshot from Network Signal Guru app displays this clearly. The Magic Box in my location broadcasts a brand new LTE carrier with frequency located on EARFCN 40270 (2558 MHz) while the macro donor eNB signal of 40978 (2628 MHz) is used as backhaul (LTE Band 25 1900 MHz can also be used). [As of July 2017, the Magic Box had its LTE carrier center frequency switched to 2518.4 MHz or EARFCN 39874. Signal Check Pro screenshot] This means, instead of a weak edge of cell LTE signal with the accompanying band switching that substantially impact device stand by times and I may lose deep inside the building, a Magic Box allows a Sprint device to connect to a strong and clean LTE 2500 MHz signal which blankets the formerly weak LTE coverage area. As a side effect, LTE speeds may also be dramatically increased due to the better signal level and quality being broadcasted by the MB whose LTE Relay Module can connect to what may have been previously an unusable 2500 MHz network. Especially when placed by a window as recommended. Album of Screenshots Personal Experience In my more than one month of observations using the Magic Box, I was able to connect to a LTE 2500 MHz signal from inside a suburban family residential building where such a signal was previously unusable. Furthermore, not only did the Magic Box boost the data signal from weak edge of cell service with consistent frequency swapping that had previously killed our devices battery life, but it also increased the LTE data speeds substantially to the tune of 200-300% over what we were previously getting over LTE 800 and 1900 MHz. Whereas previously the house was a weak coverage area where LTE 800 MHz was predominant with even parts dropping to EVDO 3G, the new LTE signal broadcasted by the MB covers the entire house and then some through multiple interior walls and even an exterior brick wall before handing over back to the macro network. So what's my view on the Magic Box? It can't come soon™ enough for more people to use and enjoy.
