Overview

ISO/IEC 14543-3-11:2016 - "Information technology - Home electronic system (HES) architecture - Part 3-11: Frequency modulated wireless short-packet (FMWSP) protocol optimised for energy harvesting" defines OSI Layers 1–3 for a low-power, frequency‑modulated wireless protocol designed for energy‑harvested devices in home environments. The standard specifies the architecture, physical layer, data link layer and network layer behaviour to enable extremely low energy consumption for sensors, switches and other HES components that may operate without batteries.

Key topics and technical requirements

• OSI scope: Physical, Data Link and Network layers tailored to short-packet FM transmission.
• Physical layer (Layer 1): Frequency‑modulated signalling optimized for robustness in mobile and variable-antenna environments; transmitter and receiver performance and packet structure are specified.
• Data link layer (Layer 2): Telegram and packet formats, integrity checks and handling for short payloads (special handling for telegrams < 8 bytes and > 7 bytes).
• Network layer (Layer 3): Media access control strategies including listen‑before‑talk (LBT), random access methods, and repeater behaviour to extend reach inside homes.
• Energy harvesting focus: Protocol design minimizes radio on-time and duty cycle to suit devices powered by harvested ambient energy (mechanical, solar, thermal, etc.).
• Packet/telegram relationship: Defined packet fields and extended headers to support variable identifier lengths, payloads and repeat counts (notably increased repeat steps compared to AM variant).
• Interoperability & conformance: Conformance clauses and normative references ensure devices from different vendors interwork in a common home network (HES).

Practical applications

• Batteryless or ultra‑low‑power sensors and actuators: wall switches, motion sensors, window/door contacts.
• Home automation control: lighting, blinds, HVAC triggers, security notifications and simple status updates.
• Retrofit solutions: radio links replacing wired installations where wiring or regular battery maintenance is impractical.
• Mobile or handheld energy‑harvested controls where antenna impedance varies with handling.

Who should use this standard

• Device manufacturers designing energy‑harvested or low‑power wireless products.
• SoC and RF module designers implementing FM short‑packet transceivers.
• System integrators and home automation vendors ensuring cross-vendor compatibility.
• Test labs and certification bodies tasked with conformance testing against ISO/IEC HES requirements.
• Standards engineers creating interoperable home network solutions.
