  1. 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.

  3. Nice Flexi zone we have there! Good find!
  4. Nokia Networks (formerly Nokia Solutions & Network [NSN]) FZHJ Flexi Multiradio 10 BTS RF module 2.6ghz Model: VBNFZHJ-01 / FZHN Assigned Vendor Region Full Build Ericsson upgraded Network Vision + Nokia 8T8R setup Special Case "Tri-Band Antenna" Setup Deployed for engineering reasons these sites do not deploy a dedicated 8T8R antenna for 2.5 but instead opts for a three frequency antenna that supports 800 MHz + 1900 MHz and 2500 MHz. Due to size constraints for the antennas they limit the 8T8R RRUs to 4T4R mode (4 Jumpers from radios to antennas).

  5. The Boogah King small cell is now live and boy what a difference in coverage and speeds it is. From barely 1-2 mbps on B25 / 26 at -110s range to 20-30s on B41 in the -80s to 100s range. Side note to all the folks around -- stay safe and wear those N95 masks!
  6. Tim YuSprint 4G Rollout UpdatesWednesday, September 12, 2018 - 12:45 PM PDT [Edit] It has come to the attention of S4GRU that the Magic Box also supports CDMA Voice Today, Sprint announced the newest Magic Box™ to the world. This Magic Box was first spotted in early summer and S4GRU did a quick write up on it here. Today's announcement formally revealed what new technologies this 3rd Generation public release will give to us. The highlights: This is some huge stuff here especially for technology nerds! Previous Magic Box's only utilized LTE UE Relay for backhaul up to 2 carrier aggregation at 2x2 MIMO at 64 QAM modulation. With 3 CA, 256 QAM, and 4x4 MIMO, this new Magic Box has the same capability as a Gigabit Class device on the Sprint™ network! In addition the notes about Wi-FI connection working for backhaul are huge. Sprint Band 25 or Band 41 may not reach indoors or even in some neighborhoods due to macro coverage patterns even though a Magic Box is available to use in a region. By having the option to use locally supplied internet via WiFi as backhaul, this allows Magic Boxes to enter locations where LTE UE Relay does not work. In addition, the ethernet port tidbit may also be a hint that using ethernet backhaul could also be an option. If so, this Magic Box would potentially support 3 choices of backhaul all in one unit; LTE UE Relay, WiFi, and Ethernet! Wow! With the coming arrival of VoLTE opt in in the near future, LTE coverage indoors is a huge concern. The now expanded reach of this new Magic Box into places previously unreachable is a huge step forward. Exciting! Sprint and Airspan sure loves Magic!
  7. For all things magic box.
  8. A quick thing I made up yesterday after looking at the FCC documents. This is currently what was agreed to and there are additional markets still pending.

    [PSA] Sprint Soft Launches VoLTE

    Tim YuSprint 4G Rollout UpdatesWednesday, October 2, 2018 - 9:00 PM PDT Starting right now, October 3,2018 12:01 AM EST, Samsung Galaxy S8, 8+, and S8 Active users can manually download the firmware to remove Calling Plus from their devices and bring forth the VoLTE Opt-In toggle. Oh yeah. VoLTE is live on the Sprint Network™ as part of the VoLTE Soft Launch in the select markets. The roll out to the soft launch markets will be gradual over the next weeks. So have at it you folks in the first soft launch markets that are going live! Here are the first 15 initial soft launch markets with more following in the next few weeks. Atlanta-Athens Chicago Dallas-Ft.Worth Houston Indianapolis Kansas Missouri New York City Oregon-West Washington Philadelphia Pittsburgh San Francisco Bay South Bay Southern Jersey Washington DC And if you're in a soft launch market...

  10. Carriers do short term leases to coordinate a swap over after a formal deal on paper is done. Carrier A and Carrier B formally swaps spectrum on paper then do a short term lease each other back the spectrum so both carriers can continue to use the spectrum they individually held. Then at some point and time in the future, a coordinated handover occurs where the leases end and immediate ownership is taken as per the formalized swap agreement. Ex: A Carrier Spectrum 1900-1910 MHz, B carrier 1930-1940 MHz. Formal Swap so A carrier has B carriers spectrum and Vice Versa. Formal short term lease so A carrier and B carrier will still have usage and temporary ownership of the spectrum that was agreed upon to swap. ~ 6 months later ~ Coordination for spectrum handover is complete and a set date is decided Set Date: Short Term lease concludes -- spectrum coordinated in handover at X time on X day. B carrier owns 1930-1940 MHz and A carrier owns 1900-1910 MHz. This is what occurs in spectrum swaps. There are further spectrum swaps that are pending the FCC that are not yet formalized yet including major markets such as Dallas, TX and New Orleans, LA. Take a break.
  11. And iPhone's have it active with the newest beta but it isn't "officially supported" right now sooooo....
  12. Columbus, OH is VoLTE launched among a lot of other markets currently not announced.
  13. But does the call go through in those markets (outside chicago, pittsburgh, indy)?
  14. According to posts on from Sprint employees on Reddit you do get the new allocations.
  15. What happened was T-Mobile and Sprint inked a spectrum swap and subsequent leasing deal for each others spectrum that is valued at XXX amount of dollars. Spectrum is expensive and particular usable midband spectrum so the cost was highlighted. When a spectrum swap occurs the companies don't immediately hand over the spectrum. What occurs is the entities most of the time will do the formal swap on paper but immediately lease the spectrum back to each other for a specific period of time where they will coordinate a proper handover when both sides are ready. In this case Sprint and T-mobile likely both have LTE carriers on said spectrum and thus at a certain point and time in the future they both will coordinate a swap over to the spectrum they swapped. This is primarily to prevent their respectives sites from causing interference to each other.

    ^ Airscale B4/66 radios attached to Nokia RAS.
  17. This is just another regular spectrum realignment as in the past. Nothing more, nothing less. Whatever you hear from people who have very clear biases and misconceptions does not mesh with what happened in reality.
  18. I'll try and keep this as updated as possible as information becomes available. In PDF style: here Maybe i'll find one time to do one for all of Sprints devices eventually...

    Hello All

    Welcome! Maps are generally "theoretical" based on a whole sleuth of what came by summed up as black magic (RF is weird) so it's always a YMMV. The biggest issue is the essential phone you got only exacerbated what issues as it has one of the worst if not worst RF performances on any devices I've ever experienced. If your old signal was weak already then it' may just be non existent with a worse RF performing device. In that case your only alternative is using WiFI or getting a LTE Femto Cell (Magic Box / Airave 4) in a few weeks when they become available.
  20. LTE-Advance means anything above LTE-Release 9 generally speaking. Things like carrier aggregation, LTE relay, small cells, multi layer beamforming, etc etc. Gigabit class means it uses a combination of LTE-A technologies in order to each up to gigabit speeds theoretically. In this case it's utilizing 3 carrier aggregation of 20 MHz TDD plus 256-64 QAM on downlink uplink and 4x4 MIMO on eNB / UE. Thus 3x(112.5*1.33*2) for devices which comes out to around 900 mbps if you have a device capable of doing 12 MIMO streams (4 MIMO + 4 MIMO + 4 MIMO).

    Network Vision/LTE - San Antonio market

    Potentially! They did advertise "enhanced uplink connectivity" for their latest sw pdate.
  22. To be "gigabit class" you need a device capable of 4x4 MIMO on 2.5, 3x 20 MHz B41 CA, 256/64 QAM DL-UL. Sprint has been quietly turning on 256/64 QAM + 4x4 MIMO since summer time which has been the major cause of network issues recently (plus VoLTE).

    It's M-MIMO btw. MUMIMO means something completely different (multi-user MIMO).
