Overview

ISO/IEC 15149-3:2016 specifies the relay protocol for extended range in Magnetic Field Area Networks (MFAN). As part of the ISO/IEC 15149 family, this standard defines how MFAN devices (coordinator, nodes, repeaters) operate together to extend effective network coverage using low-frequency magnetic-field communication. It covers addressing, request/response codes, time-division management and MAC-layer relay functions to connect out-of-boundary nodes via MFAN repeaters (MFAN-R).

Keywords: ISO/IEC 15149-3, MFAN, magnetic field area network, relay protocol, extended range, TDMA, MFAN repeater

Key Topics and Technical Requirements

Network architecture and elements

Defines device roles: MFAN-C (coordinator), MFAN-N (node), MFAN-R (repeater).
Single MFAN-C per network; nodes and repeaters associate to it.

Time-domain management (TDMA)

Superframe structure divided into request period, response period, and spontaneous period.
MFAN-C allocates request time slots; response period is divided by device count. Repeaters may subdivide their slots to create nested superframes for out-of-range nodes.

Relay and addressing

Addressing scheme and request/response codes are defined to manage relay behavior and association/disassociation.
Repeater setup procedures and message types (e.g., RSRq, RSRs, RSRA) are specified for forming relay links.

MAC layer

Frame formats and frame types are defined, including request frames, response frames, response confirmation frames and blocks.
MAC functions include repeater set-up, data transmission timing and network status management.

Physical/air interface characteristics

MFAN uses low carrier frequencies (30 kHz–300 kHz), simple robust modulation (e.g., BPSK), and coding techniques (Manchester or NRZ‑L) to provide several kbps over several meters in harsh environments.

Applications

Extending wireless communication coverage in environments where RF propagation is poor: around metal, underground, underwater-adjacent or soil-rich settings.

Enabling reliable short-range telemetry and control in industrial, mining, agricultural, and underground infrastructure.

Supporting systems that combine wireless communication and wireless power transfer (WPT) where magnetic-field links are preferred.

Implementing robust IoT and sensor networks in harsh or metallic environments that require repeaters to reach remote nodes.

Who should use this standard

Device manufacturers and system integrators designing MFAN hardware (coordinators, nodes, repeaters).

Firmware and protocol developers implementing MAC/relay functions and TDMA scheduling.

Test labs and certification bodies validating MFAN interoperability and extended-range relay behavior.

Architects of industrial and infrastructure communications seeking standards-based magnetic-field networking solutions.
