Overview
ISO/IEC 17568:2013 - Information technology - Telecommunications and information exchange between systems - Close proximity electric induction wireless communications - specifies a physical layer (PHY) and a connection layer (CNL) for transferring data between two close-proximity entities using electric induction coupling. The standard defines signal modulation, frame formats, link procedures, and service primitives required for reliable, short-range induction-based wireless links.
Key Topics and Technical Requirements
The standard covers both PHY and CNL responsibilities and includes normative and informative annexes. Key technical topics include:
Practical Applications and Who Uses This Standard
ISO/IEC 17568:2013 is intended for designers and implementers of short-range induction communication systems where two devices communicate across very close proximity (coupler-based links). Typical applications include:
- Contactless payment terminals, access control and authentication tokens
- Wearable devices and close-range IoT sensor links
- Medical devices requiring localized, low-power data exchange
- Secure device pairing and short-range data transfer between industrial or consumer electronics
Primary users:
- Hardware and firmware engineers designing PHY/CNL stacks
- Test and certification laboratories performing conformance and interoperability testing
- System architects, integrators, and security engineers implementing secure short-range links
Related Standards
For context and system-level design, implementers often compare ISO/IEC 17568:2013 with other proximity/contactless standards and RFID/NFC specifications to select the appropriate technology for range, throughput, and security requirements.
