summary

Magma refactors the cellular core by terminating RAN protocols at the edge and using a cloud orchestrator plus one access gateway per cell site to push user datapaths to the internet, configured via SDN-like control. Evaluation uses Spirent Landslide emulation, OVS dataplane, and a bare-metal $370 board; a single gateway handles ~100 active users and ~150 Mbps. Deployments report reduced per-site costs by 43% and a 5,000+ access gateways deployed rollout supporting 8,000 radios across 49 states, while noting limits on attach rates and lack of wide-area mobility.
