Information technology — Home electronic system (HES) architecture — Part 3-10: Amplitude modulated wireless short-packet (AMWSP) protocol optimized for energy harvesting — Architecture and lower layer protocols (Adopted ISO/IEC 14543-3-10:2020, second edition, 2020-03)
Standards development within the Information Technology sector is harmonized with international standards development. Through the CSA Technical Committee on Information Technology (TCIT), Canadians serve as the SCC Mirror Committee (SMC) on ISO/IEC Joint Technical Committee 1 on Information Technology (ISO/IEC JTC1) for the Standards Council of Canada (SCC), the ISO member body for Canada and sponsor of the Canadian National Committee of the IEC. Also, as a member of the International Telecommunication Union (ITU), Canada participates in the International Telegraph and Telephone Consultative Committee (ITU-T).
At the time of publication, ISO/IEC 14543-3-10:2020 is available from ISO and IEC in English only. CSA Group will publish the French version when it becomes available from ISO and IEC.
The International Standard was reviewed by the CSA TCIT under the jurisdiction of the CSA Strategic Steering Committee on Information and Communications Technology and deemed acceptable for use in Canada. From time to time, ISO/IEC may publish addenda, corrigenda, etc. The TCIT will review these documents for approval and publication. For a listing, refer to the Current Standards Activities page at standardsactivities.csa.ca. This Standard has been formally approved, without modification, by the Technical Committee and has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group.
This part of ISO/IEC 14543 specifies a wireless protocol for low-powered devices such as energy harvesting devices in a home environment. This wireless protocol is specifically designed to keep the energy consumption of such sensors and switches extremely low.
The design is characterized by
• keeping the communications very short, infrequent and mostly unidirectional, and
• using communication frequencies that provide a good range even at low transmit power and avoid collisions from disturbers.
This allows the use of small and low-cost energy harvesting devices that can compete with similar battery-powered devices. The messages sent by energy harvesting devices are received and processed mainly by line-powered devices such as relay switch actuators, repeaters or gateways. Together these form part of a home automation system, which, when conforming to ISO/IEC 14543 (all parts), is defined as a home electronic system.
This document specifies OSI Layers 1 to 3 of the amplitude modulated wireless short-packet (AMWSP) protocols.
The AMWSP protocol system consists of two and optionally three types of components that are specified in this document. These are the transmitter, the receiver and optionally the repeater. Repeaters are needed when the transmitter and the receiver are located in such a way that no good direct communication between them can be established.
Protection against malicious attacks is handled in the upper layers and thus not treated in this document.
