  1. If you can zoom in further the frequencies are likely visible on the antenna.
  2. As a T-Mobile network user I am concerned. As a computer consultant I think it is good. From a T-Mobile business standpoint it may help justify more rural sites and puts cable companies on the defensive. Personally I would always recommend that your ISP and cell phone carrier should be different, since most people do not have different ISPs. That way if one goes down you can still communicate with the outside world (in everyday situations).
  3. I could see this varying by area and point in the implementation cycle. I could also see people thinking that Sprint roaming on T-Mobile equals what a T-Mobile customer would get, which is always a dangerous assumption when roaming on any carrier.
  4. The other issue is the number of pin types supported. The merger transition period could put high demands on this type of info given we could have a wide array of the type of actives sites.
  5. Extremely disappointed that they did not include the appendices which are covered in the table of contents. There is discussion of handset issues and areas where the new T-Mobile won't be able to retain all spectrum, but no details.
  6. My understanding is Sprint often does not place backhaul orders until the site is up and running, however I have seen that change is some cases lately. The cell site providers have started to run their own fiber in areas where zoning, pole access, and crossings (railroad, main highways) are problems.
  7. Massive MIMOs can actually eliminate the need for small cells in some circumstances. Both are often used to fill in RF shadows. In a few cases small cells have been used to fill in coverage gaps. This is of limited value since they are not on the main B41 frequency thus it might take the phone 15 minutes to find them. My guess is Sprint small cells also might not be found by drive based tests like root metrics. Better suited for eating at restaurants, hospital stays, big box stores, office buildings, etc where you will be there for a while. Once your phone spots them, it is much easier to reconnect. Of course more low band would also have eliminated these RF shadows in many cases. Don't forget that small cells help offload macro sites. In talking with various system integrators of other providers, the key issue for Sprint is lack of backhaul. Sprint has more macro sites than T-Mobile in some markets yet does worse in tests with fewer customers.
  8. Early on he did invest some money directly into Sprint. With out it Sprint would have went bankrupt at that time. Various financial methods and tech tech sharing (tiger teams, etc) as well. Just not the sugar daddy we all hoped for. Much easier to raise money for mergers than ongoing failing operations.
  9. From talking with cell site firms, T-Mobile prefers to have their own back haul. It will be interesting to see what they choose to do with Sprint's internet provider holdings -- do they sell given it is a offchute business or do they build it up?
  10. While the padding on the left definitely works, the right side appears to remain the same, based on connected to LTE and the IP address.
  11. While it is certainly true that Sprint is using less Verizon roaming, I think that is more of a function of using more T-Mobile and AT&T plus Verizon eliminating CDMA equipment from sites.
  12. https://www.fiercewireless.com/regulatory/analysts-say-carr-holding-up-fcc-order-t-mobile-sprint
  13. All of the Band 71 equipment is 5g ready. It needs smartphones and firmware updates. Hopefully the backhaul needed is already installed. Given the same bandwidth, band 71 5g is expected to be twice as fast. This may not sound like much, but when you are at the edge of the cell or indoors it could make a world of difference.
  14. Signal reaches you in a zone that is basically football shaped. Thus that building greatly affects your signal. You can test this by doing tests a few blocks in either direction. Most people think signal is in straight lines in all directions. Often more like a three leave clover or a three petalled flower. Today's antennas are actually made up of dozens of small attennas, each pointable. The other factor with band 71 is T-Mobile is reserving spectrum for 5g. In other cases more spectrum will be available later.
  15. Yes. I would pull it up for you but FCC is down: https://wireless2.fcc.gov/UlsApp/UlsSearch/searchAdvanced.jsp Message from the NSAPI plugin: No backend server available for connection: timed out after 10 seconds or idempotent set to OFF.
