Overview
SIST EN 302 408 V7.1.1:2003 establishes the technical requirements for the CTS-Fixed Part (CTS-FP) transceiver in digital cellular telecommunications systems (GSM Phase 2+). This standard is focused on the GSM Cordless Telephony System (CTS), Phase 1, particularly covering the radio subsystem and its frequency control for the CTS-FP. It applies to digital mobile cellular and personal communication services operating within the 900MHz and 1800MHz bands, namely P-GSM, E-GSM, GSM900, and DCS1800.
This document ensures that CTS-FP equipment provides reliable radio transmission and reception, robust frequency control, and interoperability within GSM networks, supporting modern cordless telephony and mobile communications infrastructure.
Key Topics
- CTS-Fixed Part (CTS-FP) Transceiver Requirements: Describes how CTS-FP devices must perform within specified environmental and operational conditions.
- Frequency Bands Supported:
- P-GSM and E-GSM (900MHz)
- DCS1800 (1800MHz)
- Radio Subsystem Frequency Control: Defines how frequency management and hopping are handled in the fixed part to ensure performance and minimize interference.
- Transmitter and Receiver Performance:
- Output power requirements
- RF spectrum management, including spurious emissions and modulation spectrum
- Sensitivity and interference immunity parameters
- Adaptive Frequency Allocation (AFA): Specification for automatic, dynamic frequency selection and hopping to optimize spectrum use and avoid interference.
Applications
This standard is vital for manufacturers, network operators, and system integrators working with GSM cordless telephony solutions in residential, enterprise, or public mobile networks. Its primary applications include:
- Cordless Telephony Systems: Ensuring in-building or on-premises wireless telephony compliant with GSM infrastructure.
- Base Station Equipment (CTS-FP): Guiding the design and certification of fixed transceiver equipment used in GSM and DCS networks.
- Spectrum Management: Enabling efficient and interference-resistant operation in the densely populated 900MHz and 1800MHz GSM bands.
- Interoperability: Facilitating smooth integration with other GSM-compliant systems and devices by adhering to standardized transmission, reception, and frequency control protocols.
By complying with this standard, equipment providers demonstrate the ability to meet essential requirements for safety, interoperability, and RF performance in GSM-based wireless telephony.
