  1. Rumors but no 888 reality yet. That, plus chip shortages and AT&T difficulties keeping phone prices high at T-Mobile.
  2. The salesperson at the store gets a commission. Make certain it is the strongest signal where you need it. They don't really want you to change back -- ie get a free line first with a t-mobile sim if you need to test).
  3. I think T-Mobile was keeping their powder dry for the EBS auction for rural and other areas, hopefully later this year. I don't think the Duo will let them get it super cheap and will rather try to adjust the rules against T-Mobile for more EBS.
  4. In terms of mmWave, he said the technology to tap the spectrum has come a long way. “When it was first launched by Verizon, I think the ranges were in the order of 500-900 meters,” said Irizarry. “We’ve been testing with Ericsson, Nokia, Qualcomm and some of the handset folks. MmWave for the home ranges up to 5 kilometers. I do think there’s a place for wireless to offer competitive offerings to the existing fixed broadband offerings.” Irizarry is from US Cellular, https://www.fiercewireless.com/tech/t-mobile-s-ulf-ewaldsson-says-time-has-come-for-fixed-wireless Obvious
  5. I think Verizon is betting on increased power levels for the C-Band, as championed by FCC commissioner Carr. From his speech at the American Enterprise Institute https://docs.fcc.gov/public/attachments/DOC-370781A1.pdf : "We should seek comment this year on increasing the power levels for CBRS operations in the 3.5 GHz band. Upping the power levels here would help align the U.S. band plan with international standards and create efficiencies for midband 5G builds in the U.S. that could span the 3.45 GHz to C Band spectrum ranges. We should take the real-world experiences we’re gaining wit
  6. It really depends on how many Sprint network users are left. Have any Sprint only sites been decomissioned yet?
  7. It a doubling of small cells from 15k to 30k. The bigger risk is a possible backlash to small cells in general if they Christmas tree out their small cells with too many antennas. I expect T-Mobile to reduce small cells given redundancy with their newly defined macro sites unless they use them for n77.
  8. Does the m in location accuracy refer to miles or meters? Clarification in the selection would be useful.
  9. Same around here. T-Mobile historically upgrades urban areas first.
  10. If your city, county, or state has a online permit system that allows public access, that is the easiest way. Otherwise talk to your local T-Mobile store manager. Typically most reps don't care. Technicians in repair centers may also follow this. The carriers typically make such info available to all of the above. Worse case you could actually go down to your local building department and ask them.
  11. The PLMN method appears to me to be often temporary. I am much more inclined to believe permits. T-Mobile also historically completed virtually all of its permits. It should also be noted here that before the merger was approved, T-Mobile moved onto some Sprint sites.
  12. The key test will be stand alone Sprint sites in rural areas. Hopefully they understand the superior coverage distance of 1x800 compared to LTE. Some small cities would benefit from more sites given greater customer density. Ohio has stopped publicly tracking rural sites so intelligence on this is quite poor. Historically T-Mobile does rural sites last. In urban areas it looks like many Sprint standalone sites could be abandoned. Some of the WISP sites are not recognized as Sprint sites by me, thus it is possible some T-Mobile sites may also be abandoned or these are new WISP sites. I
  13. I think you would need to go IPv6. At least T-Mobile is more honest than Starlink about obviously showing you it is double NATed. VPNing back the router was also an issue. The key weakness to Starlink is the actual upload speeds. In many ways IPv6 is still not ready for prime time in terms of the detailed ways people use IPv4, but we must adopt to IPv6, especially in the mobile world.
  14. Definitely a marketing approach in trying to get people to move over so far. Some of those who have moved over should have done it years ago. Starting to see permits for a few standalone Sprint sites to be converted, but only about 10 sites. About 40 co-location sites will be sold to a WISP in Columbus. AT&T is my backup plan (based on tested performance my pecking order is Sprint->AT&T->T-Mobile->Verizon.) Tempted by AT&T S21 Ultra deals, just want 500GB since there is no expansion).
