  1. Past hour
  2. I should have explicitly said cheaper. 4G will be around for a while with the average phone life at 3 years, meaning some keep their phone for 4 or 5 years or even longer.
  3. Quite a number of us have been looking at this issue for months, which I call Sequential GCI Sectors (SGS). For those unfamiliar it eliminates the special 8T8R market GCI and reorders all GCI band sectors first by sector then by band. Without software help this is uncomprehensible to most people. It took a while to get a reasonable sample of data from all sectors from various sites in various tracked markets. Sprint was also making changes and initially had various models in different markets. This has only been seen in Samsung markets, although I have looked at data from ALU and Ericsson markets. It should be noted that Mini Macros and B41 small cells are not affected. It now seems to have stabilized for a while around what is shown in ingenium's chart: Implementation is growing and is getting faster. Through the many logs I analyze I have seen it pop up in more and more markets. Still uncertain as to the reason. The latest theory is for 4x4 MIMO and 256 QAM with a long line of failed theories behind that one. There are areas of uncertainty surrounding 1) counties with portions of various b41 radius on different frequencies and 2) the handling of 4th and 5th carriers. We are hoping that Sequential GCI Sectors (SGS) in Columbus and Cincinnati will soon spread to such areas so we have a better data sample. Currently we only have the area around Youngstown to work with in this regard. Joski1624 has been key in this along with ingenium. I have handled this with a cutover date for GCIs and tracking expired b41 GCIs. Early on implementation stretched out over a couple of weeks, but it now seems entire sites are done at once. I process logs first to find any Sequential GCI Sectors (SGS) sites which are ranked into Yes, Maybe, and No. "Yes" is determined unique GCI endings which can be increased if you have detailed spreadsheet data on the site that is reasonably current. These become Approved SGS sites with the earliest one becoming the cutover date which is stored for future use. "Maybe" are unique GCI endings that don't have an expected EARFCN. Many of these are transition errors but a signification number are for sites where more data is needed. These become possible SGS sites and are flagged for followup. The approved SGS site data is then processed for new carriers and missing/changed PCIs. B41 is converted back to its old GCI including GCI sectors for this purpose plus to provide data for the expired B41 sites. The expired b41 sites is also used for Mini Macro GCIs that have been replaced with 8T8R in case they appear elsewhere in the future. This effort allows old spreadsheets to be retained. Should a market fully convert (none found so far) to Sequential GCI Sectors (SGS) it will be worth revisiting this multi-step process to simplify it. The unresolved issue of sites in counties with portions of various b41 radius on different frequencies is the most difficult for SCP. Sheets may have to track earfcns for those areas and/or store the SGS sectors for them to be properly rebuilt for SCP "national" logs. Markets with sheets will want to let SCP know the approved SGS sites as users may not be on the right band or sector to know independently. This way regular sites could be stored in their compressed format while only the SGS sites would need more entries. SCP may need to track SGS sites for markets without sheets based on past key GCI sectors. This may also be the right time for SCP to allow the direct importation of true site lat/longs as RSRP allows for easier detection of EARFCNs in transition. Another issue that would help is a more resilient error handling (retries) for rooted modem earfcns. Currently this is often tripped by other apps such as LTE Discovery (used for its airplane mode like ability) or Network Signal Guru (for bandwidth, MIMO and QAM detection). Presently you must exit and restart SCP to regain EARFCN detection in such cases. Based on past history, it is safe to assume that Sprint will not totally upgrade all sites in a market to Sequential GCI Sectors (SGS), but it will likely dominate -- it will just take a while in true Sprint fashion. Many of us S4Gru folks have retained older phones (I have 4) for assigning to different signal tracking purposes. The general public often has older phones just like these as their main phone. Without Sequential GCI Sectors (SGS) support older phones in SGS areas may soon become worthless for interactive signal detection and learning.

  5. Here's my multi-point theory on why Sprint isn't roaming on VZW for LTE: Fewer Sprint phones have B13 than B12, and at the point that you're roaming on another carrier you want that low-band signal, most of which is still B13 on VZW. VZW charges more for data roaming than AT&T does, and might not even let Sprint do LTE roaming. This is bolstered by the fact that e.g. FreedomPop uses AT&T rather than Verizon as the underlying network for its stuff...they wouldn't use it if it was expensive. Also, add the PH-1 to the list of unlocked/BYOD phones that likely have the same firmware as the Sprint version, and thus get WiFi calling (though the PH-1 doesn't have Calling Plus; fingers crossed that I get VoLTE). I've been in a few RF dead zones (yay hotels!) lately but have seen the phone drop down to native eHRPD rather than swap to roaming on e.g. T-Mo band 12, so my guess is that I won't see aggressive roaming to LTE until the VoLTE soft launch, and maybe not even then.

    UK Roaming experience?

    I'll be heading to the UK in a few months and am trying to figure out whether it's worth it to switch off of Open World (this'll be my first time out of the country, so it's not like I'm using CA/MX data anyway) and grabbing a week pass for while I'm there. Specifically, does anyone know which network Sprint roams on in the UK, and whether it's LTE roaming? If the roaming situation is less than ideal, I figure I'll keep Open World and swing by an EE or Three store to pick up a local SIM, using my 3-cent-per-MB Open World data to get there. But if I can get solid coverage on LTE, I'll gladly do the week pass thing to save the hassle of finding a SIM.
  7. Pretty sure they can slowly repurpose LTE portion of M-MIMO to 5G nr so that shouldn't be a problem in the very long run. Just like Clear equipment, and those have served their purpose quite well over the last 6 years.
  8. It is disappointing that Sprint does not have a not Massive MIMO 5G option. I assume the price would be significantly less for less robust solution that would allow for both 4G and 5NR. This would allow more places to have 5NR sooner.
  9. I say that because I had a iPad pro 9.7 on Sprint that only liked 480p even in good areas but when I switched to Tmobile or At&t I would use 1080p. Sent from my SM-G965U using Tapatalk
  10. Mine doesnt do that on my galaxy S9+. How do you know it's not a iPhone thing? Sent from my SM-G965U using Tapatalk
  11. I can go above 480p but if I leave YouTube on auto it will default to 480p even when I have a good connection and good speeds.
  12. Strange YouTube prefers 720p for me most of the time and there is a way past the video limit. It's called a VPN and yes there are free ones. The one from hubvnp is a good one. Shout out to pornhub [emoji23]. I used Nord VPN though. Sent from my SM-G965U using Tapatalk
  13. Video capped at 12mpbs and YouTube seems to prefer 480p majority of the time. I think merger or no merger I’m gone. I’ve hang in there with Sprint for years. Don’t want to go thru growing pains of intergrating networks.
  14. If the merger goes through we will barely get to enjoy the upgrades before getting transferred to tmobiles network via software update. Tmobile is fast here but they are starting to slow down a little. Meanwhile Sprint is going from 1-2mbps to 100-200 mbps all over the place. Sent from my SM-G965U using Tapatalk
  15. This sucks because it seems like Sprint waited until it announced a merger with T-Mobile to go Bonkers with the upgrades.
  16. After an OS update on my GS9+ yesterday, B66 appears to be showing correctly now. Notice it in the neighbor cell list. Usually shows up at B2 or B3. Sent from my SM-G965U using Tapatalk

    Network Vision/LTE - Baltimore Market (including Annapolis/East Shore)

    Just in Baltimore counties , still aLot clearwire sties only 20 MHz. Baltimore needs Lot more triband ans Mass mimo. volte might be problem.
  18. Sprint is going crazy in the Jax market trying to catch it up to the other markets. Sent from my SM-G965U using Tapatalk

    Sprint to Begin VoLTE Soft Launch in September

    Will Magic Boxes support VoLTE on Day 1 if they are in the VoLTE rollout area or will that be a separate thing?
  20. This can happen even when bouncing from tower to tower on the same carrier. It's tower dependent. It took me over a month one time to convince Sprint they had a tower close to my workplace with a clock set to the wrong time. Sent from my Pixel 2 using Tapatalk
  21. Refarming is still ongoing, some markets are seeing 10x10+5+5 and 15x15.
  22. Yes and root uses Samsung phones so they could of likley used the calling plus feature Sent from my SM-G965U using Tapatalk
  23. Here's a spreadsheet that I put together that shows the new GCI layout, along with some example setups (with earfcns). https://docs.google.com/spreadsheets/d/1Zhb37AO4gh2kWOz598FBrWKK478RvujRzN1G4TDLcF4/edit?usp=sharing
  24. I am afraid because it will then make sprints choice to change B25 and B26 sectors real. The changes are only confirmed on less than 10% of Pittsburgh sites. It just screws those of us that use scripts to sort our logs. It almost eliminates phones that don't show EARFCN from contributing data because of the mixed (old/new) sectors. I also lose the ability to have a continuous log that I can just dump data into then keep the best data when it gets to big because because of the changes.
  25. I would normally agree with you but that happened over a year ago with the second band 25 carrier. Ill do do some tests today to see what is on 1x and 3g.
