Overview
SIST EN 301 124 V1.2.1:2003 is a Slovenian standard that aligns with European Norm EN 301 124. Developed by the Slovenski inštitut za standardizacijo (SIST), the standard specifies requirements for fixed radio systems using Direct Sequence Code Division Multiple Access (DS-CDMA) in point-to-multipoint (P-MP) digital radio networks, operating in the frequency range of 3 GHz to 11 GHz. The document addresses essential characteristics, system architecture, radio transmission parameters, spectrum management, equipment interfaces, power, and environmental conditions for DS-CDMA point-to-multipoint systems.
The principal application of these P-MP radio systems is the provision of access to both public and private telecommunications networks. They are especially suitable for extending network services to dispersed and remote subscribers, as well as for building new access infrastructures in rural and urban environments.
Key Topics
- Frequency bands: Covers fixed service allocations between 3 GHz and 11 GHz, referencing specific sub-bands for P-MP applications as identified by CEPT.
- Access method: Provisions for Direct Sequence Code Division Multiple Access (DS-CDMA) technology, enhancing spectrum efficiency and network flexibility.
- System architecture: Defines roles for Central Station (CS), Terminal Station (TS), and Repeater Station (RS) in P-MP networks.
- Transmission and performance criteria: Specifies requirements for transmission error performance, roundtrip delay, and transparency, with reference to recognized ITU-T Recommendations.
- Spectrum mask and CW components: Incorporates detailed requirements for spectrum masks, including allowances for continuous wave (CW) components within emissions.
- Radio characteristics: Outlines transmitter and receiver specifications, channel arrangements, power control, RF interface, spurious emissions, and interference rejection.
- Subscriber equipment interfaces: Lists standardized interfaces for analogue, digital, and ISDN services, ensuring compatibility with a broad range of telecom equipment.
- Power supply and environment: Defines supported DC and AC power ranges and environmental operating conditions for both weather-protected and non-weather-protected equipment.
Applications
The practical value of SIST EN 301 124 V1.2.1:2003 lies in its support for reliable, high-capacity wireless backhaul and last-mile connectivity in fixed radio environments, particularly:
- Telecommunications access networks: Extending voice, fax, ISDN, and data services to remote, rural, or hard-to-reach areas.
- Public and private network integration: Transparent connectivity for PSTN, private data networks, and new digital services through standardized interfaces.
- Cost-efficient deployments: Radio-based systems reduce the need for extensive cabling and allow rapid setup in diverse topographies.
- Scalable subscriber access: Supports a wide range of subscriber counts, from small organizations to large-scale multiplexing for thousands of users.
- Spectrum management: DS-CDMA allows frequency re-use and high user density, maximizing spectral efficiency.
- Compliance with regulatory requirements: Enables service providers and equipment manufacturers in Europe and other regions to design, deploy, and operate P-MP radio systems in accordance with recognized standards.
