1xBTS: Network-side implementing of CDMA2000 1x
Osmocom Discourse [Unofficial]
May 10, 2026
chrosmoos has posted this on IRC and I thought it needs to be mentioned here in the forum as well. He has apparantly developed an entire “RF to core” protocol stack for CDMA2000 1x from the RF/PHY side through the RAN into the CN.
See https://1xbts.org/ for the project homepage, and GitHub - chrismoos/1xbts: CDMA2000 Open Source Cellular Network · GitHub for the git repository.
I have not personalyl used it, just briefly read over the project announcement and it looks like one hell of a job. Contratulations, Chris! And thanks for improving the landscape of FOSS implementations of [in this case legacy] cellular protocols.
