Overview

ISO/IEC 14543-3-10:2020 - Information technology - Home electronic systems (HES) architecture - Part 3-10 - specifies the Amplitude Modulated Wireless Short-Packet (AMWSP) protocol optimized for energy harvesting devices in home environments. The standard defines the architecture and lower-layer protocols (OSI Layers 1–3) for extremely low-power, short, mostly unidirectional wireless messages sent by batteryless or low-powered sensors and switches to line-powered receivers (relays, repeaters, gateways) within a home electronic system (HES).

Key topics and technical requirements

• Scope and purpose
  • Protocol optimized to keep energy consumption extremely low so energy-harvesting devices can compete with battery-powered alternatives.
  • Messages are short, infrequent and designed to minimize transmit energy and avoid collisions.
• Lower-layer specification (OSI Layers 1–3)
  • Physical layer (Layer 1): Amplitude modulation (AM) signalling; protocol variants for common HES bands such as 315 MHz and 868.3 MHz are specified with transmitter/receiver requirements and frame structures.
  • Data link layer (Layer 2): Frame and subtelegram timing, listen-before-talk behavior, and data integrity options (4-bit summation, 8-bit summation, and 8-bit CRC hash functions).
  • Network layer (Layer 3): Telegram types (e.g., switch telegrams), addressing, encapsulation and optional repeater behavior for extending range or bypassing obstructions.
• Components defined
  • Transmitter, Receiver, and optionally Repeater (for non-line-of-sight or extended-range scenarios).
• Security
  • Protection against malicious attacks is handled by upper layers and is not part of this document.
• Protocol artifacts
  • Frame definitions, subframe encoding, TX maturity timing, allocation of time slots and minimum link-budget concepts are included to ensure reliable low-power operation.

Practical applications and users

• Ideal for batteryless switches, energy-harvesting sensors (motion, contact, environmental), and retrofit home automation installations where wiring is impractical.
• Typical receivers: line-powered relay switch actuators, repeaters, and gateways that aggregate short-packet reports into a home automation network.
• Primary users:
  • Device and chipset vendors developing low-power radios and transceivers
  • Firmware and embedded systems engineers implementing AMWSP stacks (Layers 1–3)
  • System integrators and manufacturers of HES components
  • Test labs and certification bodies validating compliance with ISO/IEC HES standards
