I was just trying to see if b41 on my Sprint phone was prevalent while driving to pick up a pizza. While it was available outside my condo, coverage died out quickly west of A1A and Sprint's B25 took over. B26 inside the pizzeria. No B41 until about a quarter mile west of A1A going east towards home. Probably a B41 small cell. No T-Mobile bands appeared on my Sprint phone anywhere on that trip and scant B41 coverage. I do believe T-Mobile has much better coverage on this route. I can't wait to see what T-Mobile will do but so far nothing has changed.
And TMobile has quite the temporal leg up on deploying said mid band, pre-existing spectrum with an already well seeded device portfolio that can take advantage of their 2.5 mid band spectrum. Will the other 2 eventually catch up? Probably. Money does talk, after all. But not before TMO enjoys its solitary vacation for 18 to 24 monts!
They will certainly want to bid on some, but I suspect they will be more interested in more n41 spectrum when it goes to auction. FCC needs to get moving if this will be done before January 20th will a possible political change. Thete are many areas where they only have 55Mhz contigous b41 spectrum.
