Li-Fi in Surgery: A Study
Abstract
The operating theatre is increasingly saturated with wireless devices that contend for limited radiofrequency (RF) spectrum, creating a latent risk of electromagnetic interference (EMI) with lifesupporting equipment. Light Fidelity (LiFi), a visiblelight communication technology that modulates LED illumination to transmit data, offers a compelling, RFfree alternative for intraoperative networking. This study investigates the feasibility, performance, and clinical impact of deploying a LiFi infrastructure to support highdefinition video streaming, realtime telemetry, and secure data exchange during minimally invasive and robotic surgeries. A hybrid LiFi/RF network was installed in a tertiarycare surgical suite, integrating ceilingmounted whitelight LEDs, patientside LiFi transceivers, and a custom middleware layer that dynamically switches between LiFi and conventional WiFi based on lineofsight conditions. Over a sixmonth period, 84 procedures—including laparoscopic cholecystectomies, colorectal resections, and robotassisted prostatectomies—were observed. Quantitative metrics revealed a 3.2fold increase in average throughput (up to 1.2 Gbps), a 78 % reduction in packet latency, and a complete elimination of detectable EMI on sensitive monitoring equipment. Qualitative feedback from surgeons, anesthetists, and OR nurses highlighted enhanced visual clarity of intraoperative imaging, smoother robotic arm responsiveness, and a perceived increase in procedural safety. A costbenefit analysis projected a breakeven point within two years, driven by reductions in RFlicense fees and downtime associated with EMIrelated malfunctions. The findings substantiate LiFi as a robust, sterilecompatible, and highbandwidth conduit for nextgeneration surgical communications, paving the way for fully lightbased, interferencefree operating environments.
