    Sprint Tmobile merger Disc.

    The new T-Mobile is going to boil down to a neighborhood by neighborhood decision for Sprint customers, some of which will depend on what work gets completed by Sprint assuming merger is successful. I am assuming former Clear sites that do not get Triband upgrades are typically toast. Sites with more recent investments stand a better chance of surviving, assuming they are not co-sites. Of course all existing equipment could still be junked. 800 RRHs have the best odds, given they will likely be the last bastion of Sprint CDMA. We are seeing some 1900 firmware changes that would allow for more spectrum to be used for LTE that may affect these RRH's retention. I would also assume cabinets are toast or at least retrofitted. The main factor in keeping some of the equipment would be new equipment shortages and future 5G compatible replacements being needed in coming years. Network needs and leasing costs would be main individual site factors. I would think markets with a low Sprint Market share would lose the most Sprint sites while those with a large Sprint Market share would have better odds for unique Sprint site retention. Of course the FCC might mandate that VoLTE must cover all areas covered by Sprint CDMA, but this would mostly affect rural areas. I am also assuming that the new T-Mobile will start urban in the larger markets given T-Mobile's past history.

    Official Magic Box discussion thread

    It used to drive some of us crazy in Ohio that Sprint did not know which sites had LTE or Band 41 in terms of the coverage maps. We laboriously gave them site IDs and LAT LONGs with GCIs thrown in for good measure in spreadsheet and map formats. For LTE they did add them in a few months. For Band 41 they ended up removing the category that covered it from the coverage maps. I think the key item is if you have small cells in your area, then Magic Boxes will likely work.

  4. Actual performance will be hard to predict until we can actually do our own testing. Within several years it will also likely be quite different. I do not believe a single Massive MIMO antenna system will initially be able to cover all b41 spectrum. Sprint currently has spectrum carve-outs for small cells and Magic Boxes as they currently stand. Once 5g begins to expand to other areas beyond the ideal sites I would expect simplier less expensive alternatives to current Massive MIMO. The big question will be whether Sprint will be willing to provide 5g sites with proper backhaul, which has always been a presumption as to why 4g b41 has not scaled as expected as carriers have been added. We were getting reports of up to 80Mbps on the first single carrier b41 sites with personal observations approaching 70Mbps on some sites. All of this was well before 5 carrier, 4x4 MIMO, and 256 QAM were discussed. When you start discussing initial speed needs before 5g killer apps are invented the T-Mobile 5G 600MHz approach makes sense. Who wouldn't want the low band edge performance possibly doubled? Who knows how actual phones will perform with 5g and whether any sacrifices will be made to 4g performance not forgetting 3g either. Will all bands have latent 5g support or will new phones be needed as each band is ultimately converted to 5g? How will 5g plans be structured? Of course when discussing any wireless merger the FCC must come into play. Besides spectrum, coverage and handset transition requirements (and any MVNO protections), the key factor is the length of time. This is often far longer than predicted. I feel that positive anticipation is warranted, but results will likely come in lower than hyped given the many factors touched on above. Exciting times for S4gru members to see what actually happens.
  5. 5G for b41 should be a big win given far larger carriers ( 60 MHz wide for Sprint, 100Mhz wide for new T-Mobile) which will greatly speed uploads. Better ability to reach into RF shadows and ability to handle more custumers also a big plus.
  6. Finally getting down to the details - the densest areas will be be covered by 5G (or maybe more importantly, the busiest sites). There are likely other factors - amount of spectrum in the market, fixing RF shadows in areas where small cells are difficult for whatever reason, etc.
  7. It would be interesting to study whether this would have an effect on battery life. If it is a continuous scanning the answer would be no, but if it is done on a timed interval (perhaps ever increasing then random) then the answer may be yes for global consuming more battery than LTE mode. We know it is not purely defined by the border of the United States as I have gotten Sprint signal in Canada and Canadian signal in the U.S.

    Sprint Tmobile merger Disc.

    The key item to watch with the FCC will be if MM bands get counted. They could go down to almost the tower level in terms of what coverage is required. I would certainly expect the FCC to spend a lot of time on how customer's phones are treated. The real comparison to observe in the future is if Softbank puts in more money for more control and quicker 5G or sells out at a much later date. The closest comparison is Verizon and Vodaphone's control of Verizon Wireless. Ultimately Verizon bought out Vodaphone.

    Galaxy S9 Series user thread

    Hopefully you are also using the Google Maps off-line feature for your main driving areas, which would then speed up the traffic reporting when you have data signal since less map data would be needed at that time. Sprint drive would also help, but of course more $$.
  11. You can see some of the LTE roaming areas with Sprint, although the T-Mobile roaming primarily occurred after their Aug 31 cutoff date.

    1 phone out of 4 used for that test did not have the "Use New Sprint/Samsung Indicators" option turned on, which was the one these screen shots came from. Sorry for the error. Thanks again

    Using the latest beta at the time, I disabled EARFCN using the modem and got these results: This is not an exhaustive list. My hope is for SCP to catch the unique Sequential GCI Sectors to give an idea of what is being looked at band-wise. Perhaps this has already been fixed since that time. Thanks!

    Sprint Tmobile merger Disc.

    This merger is a growth play more than just cost savings. Verizon is just doing what Sprint has already done is terms of cost cuts. However Verizon is different in that they are trying to preserve their margins. With a far better cost structure for the new T-Mobile (depending on FCC conditions), the question will be if the merger is handled successfully, which is then what will really determine job gains or losses. The competition will not stand still while the new T-Mobile gets itself organized and motivated. Some of the new ideas will fail. How quickly do to they adjust will be key. Just because something has been tried before does not mean that it can not be successful now, for timing is everything in business.
