We present a novel architecture leveraging<br>Tailscale\u2019s WireGuard-based mesh overlay to enable cooperative<br>beamforming across geographically distributed RF nodes. Our<br>approach addresses the dual challenges of reliable inter-node<br>communication and maintaining phase coherence for constructive<br>interference. Through simulation and analysis of a 4-node array<br>at 2.45 GHz, we demonstrate up to 6 dB SNR improvement<br>over single-node operation under ideal coherence conditions.<br>Partial coherence analysis reveals performance sensitivity to<br>synchronization quality, with GPS-locked nodes achieving 5.9 dB<br>gain (98 % efficiency) while free-running nodes yield 2.7 dB (45 %<br>efficiency). Failover analysis shows sub-second recovery (250 ms<br>median) for WebSocket reconnections, enabling resilient realtime operation. The overlay mesh reduces coverage blind spots<br>and provides graceful degradation under node failures, making<br>it suitable for urban RF monitoring and SIGINT applications.<br>Index Terms\u2014cooperative beamforming, distributed RF sensing, mesh networks, Tailscale, phase coherence, failover resilience<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Distributed RF sensing systems require robust meshconnectivity and coordinated beamforming to maximize spatialdiversity gains.
