⬅️ What is DECT-2020 New Radio (NR), and how big a deal is it? (2021)
zackmorris 31 daysReload
I always wanted "wireless wires" that would look like two usb/ethernet/hdmi/etc dongles and just provide one or more connection types at a desired bandwidth, regardless of protocol. They'd be encrypted by a private key set by touching them together, or installing one file of random bytes and arbitrary size to each as a usb drive (either as a separate usb plug or a physical switch that enables storage mode).

So users could plug one into their computer and the other into a drive/router/television/etc and it would "just work" without having to fiddle with 802.11 setup friction. I wonder if DECT-2020 New Radio (NR) could be used for this?

I wanted to invent this in the early 2000s when I first saw wireless usb over wifi and thought "well that's terrible", akin to the disbelief I felt in the '90s when I saw that usb connectors were flat instead of circular and couldn't believe that someone would come up with something so ridiculously annoying. But after 20 years of something so obvious not being invented (probably due to monopoly/regulatory effects), along with the hundreds of other things I wanted to invent in another life, I can comfortably release this idea into the public domain.

It seems they have just released a developer kit https://www.nordicsemi.com/Nordic-news/2024/01/The-nRF9161-S...

For a standard published 4 years ago, I'm surprised my googling isn't showing up any reference boards or the like that would attract wannabe hobbyists like myself. Is there some fundamental problem why it doesn't seem to have made it to market?

Anyone here feeling qualified to answer the question in the title?

The article describes various aspects, such as that the new DECT version uses modulation and other mechanisms also present in cellular NR/5G, which sounds like a big step forward but, at the same time, no difference in user experience either. The networks get more secure and efficient by the sound of this vendor publication, but is there any user-visible chance? Or are the under-the-hood changes "a big deal" as they put it?
