SIST EN 301 124 V1.2.1:2003 is the Slovenian adoption of the ETSI European Standard for fixed radio systems with point-to-multipoint DS-CDMA equipment in the 3 GHz to 11 GHz range. It specifies system, radio, interface, power supply, and environmental characteristics for Central Station, Terminal Station, and Repeater Station equipment used to connect subscribers to public or private networks.

What does SIST EN 301 124 V1.2.1:2003 specify?

SIST EN 301 124 V1.2.1:2003 specifies technical requirements for point-to-multipoint digital radio systems using Direct Sequence Code Division Multiple Access (DS-CDMA) in fixed service bands from 3 GHz to 11 GHz. In practice, it tells manufacturers and buyers what performance and interface behavior the equipment should support.

The scope covers typical voice, fax, voiceband data, telex, data up to 2 Mbit/s, and ISDN applications. It is organized into scope, references, definitions, general system architecture, radio characteristics, types of subscriber equipment and network exchange interface, and power supply/environmental characteristics, plus Annex A with a bibliography.

What are the key requirements of SIST EN 301 124 V1.2.1:2003?

SIST EN 301 124 V1.2.1:2003 is centered on link performance, spectrum behavior, receiver behavior, and standardized interfaces. The most important clauses are 4, 5, and 7, because they define what the equipment must do in service and what must be declared or tested.

System performance and transparency

Clause 4.2.1 requires equipment to be designed to meet the network performance and availability objectives of ITU-T G.821, following ITU-R F.697 criteria for the local-grade portion of the digital connection. That matters because it links radio design to end-to-end service quality.

Clause 4.2.2 limits roundtrip delay for a single 64 kbit/s traffic channel to 20 ms and refers to ITU-T G.131 for telephone quality. Clause 4.2.3 expects the system to be transparent to the subscriber equipment, and it names coding options such as G.711, G.726, G.728, and G.729. In practice, the manufacturer has to declare the coding method and show that voice and data service behavior stays acceptable.

Clause 4.2.4 and 4.2.5 address the TMN interface and synchronization. If the equipment uses digital interfaces, it must support internal and external synchronization to the network.

Radio, loading, and emissions

Clause 5.1 places the standard in fixed service allocations from 3 GHz to 11 GHz, while clause 5.2 uses example channel spacings of 5 MHz, 10 MHz, and 15 MHz. Clause 5.2.1 requires the manufacturer to declare the class of operation and the maximum system loading, meaning the number of simultaneous 64 kbit/s channels that can coexist while keeping BER at or below 10^-6.

Clause 5.3 sets transmitter limits, including maximum average output power, ATPC and RTPC declaration, the spectrum density mask, the handling of discrete CW components, spurious emissions, and RF tolerance. This is the part that controls how cleanly the transmitter fits into the band and how much power the installer can expect to set.

Clause 5.4 covers receiver dynamic range, broadband CW interference rejection, BER performance, and co-channel and adjacent-channel sensitivity. These limits matter when several users share a cell or when nearby signals are present, because they show how much interference the receiver can tolerate before service quality drops.

Clause 5.5 defines the RF interface and return loss for equipment without an integral antenna. Clause 6 then points to standardized subscriber and network interfaces, and clause 7 sets supply voltage, environmental class, and EMC conditions.

What terms does SIST EN 301 124 V1.2.1:2003 define?

• chip - A unit of modulation used in Direct Sequence Spread Spectrum (DSSS) modulation.
• chip rate - The number of chips per second.
• DSSS modulation - A modulation method that combines the data signal with a fixed chip sequence to modulate the carrier.
• DS-CDMA - Direct Sequence Code Division Multiple Access, the access method used by the systems covered.
• system loading - The number of simultaneous 64 kbit/s traffic channels in one radio channel.
• maximum system loading - The declared number of simultaneous 64 kbit/s traffic channels for a stated class of operation.
• roundtrip delay - The sum of the delays between points F to G and G to F in the system model.
• CW - Continuous Wave, used in the spectrum mask and interference clauses.

Who uses SIST EN 301 124 V1.2.1:2003?

SIST EN 301 124 V1.2.1:2003 is used by equipment manufacturers, network planners, test laboratories, operators, and procurement teams working with fixed point-to-multipoint radio access. They use it to choose bands and channel spacing, declare maximum system loading, test transmitter and receiver performance, check interface types, and verify environmental and power-supply suitability.

What changed in SIST EN 301 124 V1.2.1:2003 from the previous edition?

The document history shows an earlier V1.1.1 publication and this V1.2.1 publication. The scope states that this version inserts a subsection on CW components within the spectrum-mask section.

What does the SIST EN 301 124 V1.2.1:2003 document contain?

SIST EN 301 124 V1.2.1:2003 contains a general system architecture figure, an RF block diagram, and tables for channel spacing, dynamic range, BER thresholds, maximum system loading, co-channel and adjacent-channel sensitivity, power supplies, and standardized interface types. It also includes the spectrum mask, the CW-component allowance, transmitter output-power and RF-tolerance limits, receiver interference tests, and environmental and EMC conditions.

For design and testing, the most useful parts are the declared operating classes, the measurement points, and the tables that define pass criteria for loading, BER, interference rejection, and interface behavior.
