AI Analysis

●●●●GemWizardryZero to One

Entire CDMA2000 stack in Rust lets you run a private cellular network on an SDR.

Strengths
  • •Complete stack from RF to core including HLR, SMSC, and packet data in one project.
  • •Rust implementation ensures memory safety for critical telecom infrastructure components.
  • •Supports real 1.25 MHz channels with Walsh code spreading and Viterbi decoding.
Weaknesses
  • •Requires specific SDR hardware and RF knowledge, limiting accessibility for generalists.
  • •CDMA2000 is legacy technology; modern networks use LTE and 5G NR standards.
Target Audience

Telecom engineers, SDR hobbyists, and network researchers
