    Official Magic Box discussion thread

    You folks should probably take the discussion of how MB fits into the T-mobile network into that appropriate thread instead of this one.
  3. VoLTE will be a market specific opt in option. It's already live on the network for closed testing and in some areas production network testing.

    LG G5 User Thread (LG-LS992)

    For those who have acquired the LG G5 & want to talk about it.
  5. 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.
  6. Tim YuSprint 4G Rollout UpdatesFriday, June 8, 2018 - 3:00 PM PDT It has been a little over a year since the first Magic Box publicly available was announced. In the time since then since the Airunity 545 "GEN 1" was announced, minor revisions were done as "GEN 2" with the Airunity 544 sporting a LCD display and subsequently the Airunity 546 having an more aesthetically pleasing exterior. All LCD display models are known as "GEN 2" respectively. Come next week starting on June 11th, 2018, the GEN 2 Magic Box's (AU544/546) will be considered out of stock and a GEN 3 Magic Box will take over the reigns in the beginning of July 2018. Though information on this new unit is scarce, information attained by S4GRU does suggest the new revision may potentially contain user accessible USB Type A ports and have a slightly lower transmit power. More to come as S4GRU discovers additional information about this GEN 3 Magic Box.

    http://s4gru.com/forums/topic/7711-official-magic-box-discussion-thread/?do=findComment&comment=529863 I have a good lead on what the Relay module will be but will not state anything until further confirmations. No. Airspan is strictly a LTE RAN and future NR RAN provider. Voice will be supported when opt in VoLTE becomes available this coming fall.

  9. Any and all 31/32/33 39/3A/3B endings are Nokia Mini Macros on Macros typically found on former Clearwire sites. Each mini macro is a stand alone BTS so will have unique GCI identifiers. For old Samsung GCI endings... B25 #1 = 00/01/02 B25 #2 = 03/04/05 B25 #2 10x10 = 06/07/08 B26 = 10/11/0F B41 #1 = 00/01/002 B41 #2 = 03/04/05 B41 #3 = 06/07/08 B41 #4 = 0C/0D/0E B41 Triband Antenna #2 = 09/0A/0B B41 Triband Antenna #3 = 03/04/05 Airspan Airunity MBGCI endings are all over the place but it's easy to pick out once you know the standard GCI heading. Airspan airharmony mini macros GCI ends 01.

  11. That appears to be similar to Samsung and I assume Nokia and ALU regions when 3CA was beginning to roll out. It turned out there was still backend upgrades that needed to be done.
  12. Center frequency 1939.4 MHz so upper part of A block. The entirety of the PCS A block 1930-1945 is owned by Sprint. Shown on the interactive maps..
  13. The backhaul is connected to the SFP backhaul ports so that's fiber! (left 2 = ethernet 802.3AT, right 2 = SFP)

    Mobilitie Sites

    Relays can be used temporarily to bring up sites immediately while dedicated traditional landlines are delivered. In fact, it's one of the touted benefits of the technology. Sprint small cells don't need to wait weeks to months for backhaul to arrive like back during NV days. Also yes. That's an Airharmony 4000 B41 mini macro connected on its ethernet backhaul port to a provider of some sort. Actually now that I think of it, you're the first one to confirm with pictures an AIrspan small cell connected to what appears to be a landline backhaul. Were you able to grab any cell info from it like carriers live or EARFCN?

    It may get better over time as it self optimizes but the increase in ping is to expected as I explained previously due to the additional hop as a result of the UE relay action. I typically get 30-40 ms on the macro network and 60-70 ms on the MB and relay fed small cells. Sent from my Pixel using Tapatalk

    With regards to slower data speeds, aim the back of the unit towards the 2.5 cell site you know works well. It sounds like you've accidentally aimed it at a slower site. The UE Relay antennas are extremely directional.

    Official Magic Box discussion thread

    Have you read anything about it or generally about LTE UE Relay in particular? A Magic Box, and most relay fed small cells adds a hop due to the fact it has to convert the connection from an LTE donor signal into a data ethernet connection for the small cell unit as a backhaul. As a result, latency is added which is usually twice that of the donor. Not sure why you're disparaging the MB like you did when it's working as described...
  19. Sooo... found one of the first live small cell in Sacramento. Yay.
  20. by Tim Yu and Andrew J. Shepherd Sprint 4G Rollout Updates Sunday, December 6, 2015 - 2:55 AM MST S4GRU staff is burning the well past midnight oil for our readers. Overnight, Sprint has unofficially updated its network coverage map tool to include LTE Roaming+ and LTE Roaming acquired via its participation in the Competitive Carriers Association (CCA) Roaming Hub and its own Rural Roaming Preferred Partners (RRPP) program. The coverage tool LTE roaming update clearly is a work in progress -- more on that later. But LTE roaming is finally here. So, what is the difference between LTE Roaming+ and LTE Roaming? LTE Roaming+ A simple explanation is that LTE Roaming+ is pseudo native coverage. Sprint users will access certain other LTE networks without roaming restrictions and can treat them as native. Usage does not count against any roaming cap, the only restrictions being the plan type ("unlimited" vs data allotment). LTE Roaming LTE Roaming is non native, off network coverage. Usage is counted against Sprint plan roaming caps. Older plans, such as the Everything Data, have a 300 MB limit, while newer plans, like Framily, are limited to 100 MB. For a specific LTE roaming footprint example, see this coverage tool screenshot centered around Sprint's headquarters in the Kansas City metro. From the LTE roaming legend, the dark green LTE Roaming+ in western Kansas is Nex-Tech Wireless, and you can catch a glimpse of the same LTE Roaming+ from C Spire south of Memphis. The light green is LTE Roaming, all of which appears to be USCC at this point. Elsewhere, you will find LTE Roaming on USCC in its Pacific Northwest, Southeast, and New England regions. There is still map work to do -- note the LTE Roaming legend "@TODO will we have a description here?" More LTE Roaming+ and LTE Roaming operator coverage may be added in the coming hours or days. Device compatibility? Due to Sprint's unique LTE Band 25-26-41 network configuration, not all Sprint LTE capable devices will be able to roam on partner networks, which may use different bands, such as Band 2 (PCS 1900 MHz A-F blocks), Band 4 (AWS-1 1700+2100 MHz), Band 5 (Cellular 850 MHz), and Band 12 (Lower 700 MHz) As such, a CCA/RRPP compatible Sprint triband device, of which many were released in the past year, is the best bet for full network compatibility with partner LTE networks. A CCA/RRPP device will have LTE Band 2-4-5-12-25-26-41 support, which basically covers all of the standard LTE bands in use in the US -- minus VZW Band 13 and AT&T Band 17. No matter, VZW and AT&T presently are not LTE roaming partners with Sprint. If Multi Frequency Band Indicator (MFBI) is active at the network level, a regular Sprint triband device (Bands 25-26-41) may be able to access some partner networks -- due to Band 25 (PCS 1900 MHz A-G blocks) and Band 26 (eSMR 800 MHz + Cellular 850 MHz) being supersets of Band 2 and Band 5, respectively. However, these triband devices will not roam if the partner network uses Band 4 or Band 12. An older single band Sprint LTE Band 25 device will be even more restricted. If it can roam at all, it will be limited to partner networks that use Band 2, again assuming MFBI. In Summary... A few months ago, Sprint upgraded much off network coverage for most accounts from only CDMA1X to EV-DO. Now, a lot of that same roaming footprint gets elevated a second time to LTE. Sprint LTE, eHRPD/EV-DO, and CDMA1X coverage still will hold highest priority. Whether LTE Roaming+ or LTE Roaming, it will not supersede Sprint eHRPD/EV-DO or CDMA1X signal. But outside of all Sprint native coverage, roaming gets another boost. LTE roam, roam if you want to. Sources: Sprint, S4GRU thread
  21. 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!
