Overview
IEC 60050-713:1998/AMD5:2021 is the fifth amendment to Part 713 of the International Electrotechnical Vocabulary (IEV), issued by the International Electrotechnical Commission (IEC). This amendment specifically addresses terminology related to radiocommunications, covering key components such as transmitters, receivers, networks, and operational concepts. The document provides updated and precise definitions of technical terms essential for the standardization and harmonization of communication technologies globally, facilitating clear communication among professionals in telecommunications and related fields.
This standard serves as a vital reference for engineers, researchers, and practitioners involved in the development, deployment, and regulation of radiocommunication systems.
Key Topics
The amendment includes terminology updates and clarifications for a comprehensive set of radiocommunication concepts, including:
- Earth Station: Defined as a radio station located on the Earth's surface or within its atmosphere, intended for communication with space stations or other similar stations via satellites or space objects.
- Coverage Area: The geographic area on Earth’s surface where communication with a specific space station is possible under defined technical conditions.
- Connection by Satellite: A radio link established through one or more satellites and optionally via Earth stations between transmitting and receiving stations.
- Frequency-Hopping Spread-Spectrum Modulation: A modulation technique where the carrier frequency rapidly changes pseudo-randomly across a broad frequency band to improve communication reliability and resistance to interference.
- Antenna Gain Definitions: Terms such as absolute gain, equivalent isotropically radiated power (EIRP), and effective radiated power (ERP) are clarified to describe antenna performance in transmitting or receiving radio signals.
- Disturbance Suppression: Techniques focused on reducing or eliminating radio-frequency interference at its source to improve system performance.
These updated definitions are grounded in internationally recognized technical standards and ITU Radio Regulations, ensuring consistency and global acceptance.
Applications
The terminology amendments in IEC 60050-713:2021/Amd5 are critical for various practical applications including:
- Satellite Communications: Enhancing clarity in the design, deployment, and regulation of Earth stations and space communication links.
- Wireless Network Design: Standard definitions assist in the accurate description of network components, operational parameters, and modulation types, critical for network interoperability.
- Telecommunication Standards Development: Facilitates uniform terminology across international documentation, ensuring accurate interpretation in standards, specifications, and regulations.
- Educational and Technical Training: Provides a reliable vocabulary for training materials and technical education in radiocommunication technologies.
- Interference Management: Offers standardized terms to describe and implement disturbance suppression techniques to maintain network quality.
By aligning vocabulary globally, the amendment supports the telecommunications industry’s pursuit of effective and reliable communication systems.
Related Standards
IEC 60050-713 Amendment 5 relates closely to other parts of the International Electrotechnical Vocabulary and numerous international norms such as:
- IEC 60050 Series: Comprehensive vocabulary covering various electrotechnical domains.
