fun thing is a bunch of hobbyists are running around with SDRs and old cell hardware and running low power experimental cell networks in their houses, questionable legality be damned.
OpenBTS/YateBTS/OsmoBTS and friends are useful here to spin up a working network and relive a happier time.
I've been meaning to get one of the tiny SDR cards like an XRTX and place it into a Pi or similar device and build a "mobile mobile hotspot" - LTE/5G in, 2G/3G out for old crap.
EDIT: I almost forgot, too. The N95 has Wi-Fi and a SIP client, so it's not completely useless even in 2026!
That's actually a very interesting idea - do you have any good resources for setting this up ?
There are some cars that can only access 3G for certain features and it would be cool to test around and see what my vehicle can do and if I want to disable it for reliability reasons
802.11b/g :(

Indeed, but good luck setting something like that up and not upset a legitimate cell tower or other user of a frequency band that can be spoken by LTE equipment.
