Description: This work proposes a structured, lossless extension to the IEEE 802.15.7 Visible Light Communication (VLC) standard to enable bit‑exact transport of IEEE 754 floating‑point values over Li‑Fi physical and MAC layers. The amendment introduces a new MAC‑layer Information Element (IE754‑IE) designed to encapsulate raw IEEE 754 binary32 and binary64 payloads without reinterpretation, modification, or rounding. To guarantee mathematical fidelity, the proposal defines a mandatory systematic forward‑error‑correction (FEC) profile and CRC‑based integrity mechanism that together ensure complete preservation of IEEE 754 semantics, including NaNs, infinities, subnormals, and payload‑encoded diagnostic metadata. The document provides normative clause additions for MAC framing, PHY encoding, capability negotiation, and error‑control requirements, written in the style and structure of IEEE amendment text. The goal is to support scientific, industrial, and control‑system applications that require deterministic, lossless floating‑point transport over short‑range optical wireless channels. This proposed amendment demonstrates how Li‑Fi systems can be extended to carry computationally meaningful numerical data with full IEEE 754 compliance, enabling new classes of high‑integrity optical networking applications.
