What is 1xbts?

1xBTS builds a full open-source CDMA2000 1x cellular network in Rust, handling base station, core elements like MSC and HLR, voice calls, SMS, and packet data over SDR hardware. It revives legacy CDMA2000 devices—think old iPhones or Motorolas—by broadcasting a complete cdma2000 cellular technology stack you control, either as a network-in-a-box or split nodes. Users get a web dashboard for live monitoring of channels, mobiles, power control, and sessions, plus Docker quickstarts for Postgres and FOU tunnels.

Why is it gaining traction?

No other open CDMA2000 stack exists, so 1xBTS fills a niche for testing US carrier relics ignored by GSM/LTE alternatives. The dashboard shines with real-time charts for radio metrics, event streams, and controls like SMS sending or packet captures, all backed by gRPC APIs. Rust delivers low-latency radio handling that feels solid out of the box on bladeRF or USRP.

Who should use this?

RF engineers validating cdma2000 handsets in labs. Protocol tinkerers debugging air-interface quirks on SDRs. Hobbyists building private cellular networks for voice, SMS, or data with tested phones like Nokia Lumia or BlackBerry.

Verdict

Early with 46 stars and 1.0% credibility, but active dev, good docs at 1xbts.org, and working features make it worth a spin for cdma2000 cellular technology experiments—just don't bet production on it yet. Pair with supported SDR for quick wins.
