Information technology — Telecommunications and information exchange between systems — Magnetic field area network (MFAN) — Part 1: Air interface

ISO/IEC 15149-1:2014 specifies the physical layer and media access control layer protocols of wireless network over a magnetic field in a low frequency band (~300 kHz) for wireless communication in harsh environment (around metal, underwater, underground, etc.). The physical layer protocol is designed for the following scope: low carrier frequency for large magnetic field area and reliable communication in harsh environment; simple and robust modulation for a low implementation cost and error performance; variable coding and bandwidth for a link adaptation. The media access control layer protocol is designed for the following scope: simple and efficient network topology for low power consumption; variable superframe structure for compact and efficient data transmission; dynamic address assignment for small packet size and efficient address management. ISO/IEC 15149-1:2014 supports several kbps data transmission in wireless network within a distance of several metres. It can be applied to various services such as the following areas: environmental industry to manage pollution levels in soil and water using wireless underground or underwater sensors; construction industry to monitor the integrity of buildings and bridges using wireless, inner-corrosion sensors; consumer-electronics industry to detect food spoilage in wet, airtight storage areas and transfer the sensing data from the inside to the outside; agricultural industry to manage the moisture level as well as mineral status in soil using wireless, buried sensors; transportation industry to manage road conditions and traffic information using wireless, underground sensors.

Foreword
ISO (the International Organization for Standardization) and IEC (the International Electrotechnical
Commission) form the specialized system for worldwide standardization. National bodies that are
members of ISO or IEC participate in the development of International Standards through technical
committees established by the respective organization to deal with particular fields of technical
activity. ISO and IEC technical committees collaborate in fields of mutual interest. Other international
organizations, governmental and non-governmental, in liaison with ISO and IEC, also take part in the
work. In the field of information technology, ISO and IEC have established a joint technical committee,
ISO/IEC JTC 1.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for
the different types of document should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject
of patent rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights.
Details of any patent rights identified during the development of the document will be in the Introduction
and/or on the ISO list of patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

assessment, as well as information about ISO’s adherence to the WTO principles in the Technical Barriers
to Trade (TBT) see the following URL: Foreword - Supplementary information
The committee responsible for this document is ISO/IEC JTC 1, Subcommittee SC 6, Telecommunications
and information exchange between systems.
This first edition of ISO/IEC 15149-1 cancels and replaces ISO/IEC 15149:2011, of which it constitutes a
minor revision.
ISO/IEC 15149 consists of the following parts, under the general title Information technology —
Telecommunications and information exchange between systems — Magnetic field area network (MFAN):
— Part 1: Air interface
— Part 2: In-band Control Protocol for Wireless Power Transfer
Relay Protocol for Extended Range and Security Protocol for Authorization will form the subjects of future
Parts 3 and 4, respectively.

Introduction
This International Standard provides protocols for magnetic field area network (MFAN). MFAN can
support the service based on wireless communication and wireless power transfer in harsh environment.
MFAN is composed of four protocols: air interface, in-band control protocol, relay protocol, and security
protocol.
This part of ISO/IEC 15149 specifies the physical layer and media access control layer protocols of
wireless network over a magnetic field.
ISO/IEC 15149-2 specifies the control protocol for wireless power transfer based on magnetic field area
network.
ISO/IEC 15149-3 specifies the relay protocol to extend effective network coverage of magnetic field area
network.
ISO/IEC 15149-4 specifies the secuity protocol to authorize nodes to communicate in magnetic field
area network.

INTERNATIONAL STANDARD ISO/IEC 15149-1:2014(E)
Information technology — Telecommunications and
information exchange between systems — Magnetic field

Part 1:
Air interface
1 Scope
This part of ISO/IEC 15149 specifies the physical layer and media access control layer protocols of
wireless network over a magnetic field in a low frequency band (~300 KHz) for wireless communication
in harsh environment (i.e., around metal, underwater, underground, etc.).
The physical layer protocol is designed for the following scope:
— low carrier frequency for large magnetic field area and reliable communication in harsh environment;
— simple and robust modulation for a low implementation cost and error performance;
— variable coding and bandwidth for a link adaptation.
The media access control layer protocol is designed for the following scope:
— simple and efficient network topology for low power consumption;
— variable superframe structure for compact and efficient data transmission;
— dynamic address assignment for small packet size and efficient address management.
This part of ISO/IEC 15149 supports several Kbps data transmission in wireless network within a
distance of several meters. It can be applied to various services such as the following areas:
— environmental industry to manage pollution levels in soil and water using wireless underground or
underwater sensors;
— construction industry to monitor the integrity of buildings and bridges using wireless, inner-
corrosion sensors;
— consumer-electronics industry to detect food spoilage in wet, airtight storage areas and transfer
the sensing data from the inside to the outside;
— agricultural industry to manage the moisture level as well as mineral status in soil using wireless,
buried sensors;
— transportation industry to manage road conditions and traffic information using wireless,
underground sensors.
