Huh, so, apparently, T-Mobile is starting to consider turning down their LTE network, with the idea that other carriers may follow. This seems weird to me for a few reasons:
As far as I understand, there still isn’t really a good #LTE cat-M replacement story in the 5G-NR world? There’s 5G #RedCap / NR-Light, but I don’t know of any readily available RedCap modems, and I feel like that’s more in the LTE cat1bis class than in the catM1 class. What happens there in a post-LTE-shutdown world?Also, I thought this was the whole point of #DSS / dynamic spectrum sharing – you’d be able to reallocate bandwidth between LTE and 5G/NR on the same channel, and the PHY for NR was designed to be able to run at the same time as a LTE PHY. (Though in reality, it didn’t really work, maybe?) What went wrong here that does not allow a ‘lifeline’ LTE service to run on every NR channel? One wonders if NR’s PHY is futureproofed against this.I am just a sparky and my understanding of radio access technologies is pretty limited. If anyone actually knows, or knows someone who might actually know, I would be very curious to hear…
