summary

Real-time LTE and 802.11 PHYs run on USRP-2974/2953 FPGAs using NI Application Frameworks and connect to ns‑3 via a vendor‑independent L1–L2 API so simulated topologies use real OTA radio. Message types, timing (1 ms LTE tick), and transports (Linux pipes for LTE, UDP for relaxed Wi‑Fi) are implemented; end‑to‑end tests show about ~70 Mbps measured toward the LTE theoretical limit, code and API docs live on GitHub, and the setup is validated for multi‑RAT experiments as ns-3 integration API on USRP-2974/2953.
