Democratizing Cellular Access with AnyCell

on YouTube ↗21m

" summary

Claim: let any user attach to any operator on demand without pre-established trust by moving subscriber/auth and billing into a broker and mobility into the device. Prototype on Magma + srsLTE over USRP implements three-way public‑key attachment with brokerd and UE-driven mobility using mptcp/QUIC. Crypto processing adds <2 ms, attachment saves one RTT versus standard, and end‑to‑end app impact is negligible (−1.6% to +3.1% across iperf, video, web, VoIP), showing the design works.
