SIST EN 301 997-1 V1.1.1:2003

• Abstract:

  Equipment performance characteristics and parameters necessary to facilitate coexistence between broadband Multimedia Wireless Systems (MWS) in either; adjacent frequency assignments in the same geographical area. or co-frequency assignments in neighbouring geographical areas. Multimedia Wireless Systems are defined as terrestrial multipoint systems which have their origin in telecommunication and/or broadcasting, and which provide fixed wireless access direct to the end user for multimedia services. These MWS systems may offer different degrees of interactivity.Therefore systems are anticipated that could deliver services requiring either asymmetric data rates, (including uni-directional distribution systems) or symmetric data rates between uplink and downlink. Any asymmetry between uplink and downlink may be fixed or dynamically variable to suit the traffic characteristics at any time. This standard covers equipments that operate within the frequency band 40.5 to 43.5 GHz.

SIST EN 301 997-1 V1.1.1:2003 is the Slovenian adoption of ETSI EN 301 997-1 V1.1.1 for radio equipment used in Multimedia Wireless Systems (MWS) in the 40.5 GHz to 43.5 GHz band. It specifies the general equipment and system parameters needed to plan coexistence between MWS deployments and to define the interfaces, transmitter and receiver characteristics, and operating conditions for manufacturers, operators, and test laboratories.

What does SIST EN 301 997-1 V1.1.1:2003 specify?

SIST EN 301 997-1 V1.1.1:2003 sets minimum requirements for MWS equipment operating in the 40.5 GHz to 43.5 GHz band, with a focus on coexistence planning between systems in adjacent assignments or neighbouring geographical areas. It applies to systems used for telecommunications and entertainment services and covers both FDD and TDD operation.

The document is organized into:

• Clause 3 - definitions, symbols, and abbreviations
• Clause 4 - general characteristics
• Clause 5 - system parameters
• Clause 6 - types of interface
• Annexes A to D - spectrum, regulatory, receiver, and ATPC material

Annex	What it covers
A	Intra-block minimum requirements
B	EIRP and block-edge mask regulatory considerations
C	Matched receiver block-edge selectivity mask
D	Example ATPC method in the uplink direction

What are the key requirements of SIST EN 301 997-1 V1.1.1:2003?

SIST EN 301 997-1 V1.1.1:2003 is mainly about keeping nearby MWS systems compatible by controlling spectrum use, timing, interfaces, and emission levels.

• Clause 4.1 describes an MP topology with Central Station (CS), Terminal Station (TS), and Repeater Station (RS), connected through Network Node Interface (NNI), Service Node Interface (SNI), and User Network Interface (UNI). In practice, this tells you how the radio part fits into access, broadcast, or mixed networks.
• Clause 4.2 requires operation in the 40.5 GHz to 43.5 GHz band using a block-based frequency plan. Channels near a block edge must be spaced so the equipment stays within the block-edge criteria used for inter-operator coordination.
• Clause 4.4 ties environmental performance to EN 300 019 classes, and the manufacturer must declare the class the equipment is built for. This matters when choosing indoor, sheltered, or outdoor hardware.
• Clause 4.5 places the power supply interface under ETS 300 132-1, EN 300 132-2, and safety requirements under EN 60950. This is the basis for matching the radio unit to the site power system safely.
• Clause 4.6 requires compliance with EMC conditions from EN 301 489-1, EN 301 489-4, or EN 300 385. That is the practical route for controlling interference and meeting radio-safety expectations.
• Clause 4.7 requires synchronization methods for services that need aligned interface bit rates, with timing principles from ITU-T G.810 and tolerances from G.812, G.823, G.813, and G.825. In practice, this is important for circuit-like traffic such as CBR services.
• Clause 5.2 limits roundtrip delay for 64 kbit/s circuit-switched telephony to 20 ms, and Clause 5.3 links voice services to declared coding methods such as G.711, G.726, G.728, G.729, or G.723.1. This helps buyers compare voice quality and delay behavior.
• Clause 5.5 controls transmitter behavior: output power, Automatic Transmit Power Control (ATPC), optional Remote Transmit Power Control (RTPC), optional Remote Frequency Control (RFC), RF spectrum masks, spurious emissions, and RF tolerance. These are the core coexistence controls.

What terms does SIST EN 301 997-1 V1.1.1:2003 define?

• block-edge - the frequency boundary between one assigned block and a neighbouring block, often belonging to another operator.
• frequency block - a contiguous portion of spectrum typically assigned to a single operator.
• Full Capacity Load (FCL) - the maximum traffic load a CRS can carry within a specified RF bandwidth while still meeting performance and availability targets.
• roundtrip delay - the total delay from SNI to UNI and back again, including repeaters where present.
• Automatic Transmit Power Control (ATPC) - a control method that adjusts transmit power automatically to maintain link performance under changing propagation conditions.
• Remote Frequency Control (RFC) - a feature that lets frequency channel settings be adjusted remotely across the declared tuning range.

Who uses SIST EN 301 997-1 V1.1.1:2003?

SIST EN 301 997-1 V1.1.1:2003 is used by radio equipment manufacturers, system vendors, network operators, and test laboratories working on fixed wireless access and multimedia radio systems. It is also relevant to regulators and spectrum planners because it links equipment behavior to block-based frequency coordination, EIRP control, and block-edge compatibility.

Which standards are used with SIST EN 301 997-1 V1.1.1:2003?

The main companion references are:

• CEPT/ERC/REC01-04 - the coordination framework for MWS blocks and block-edge use.
• EN 300 019 - environmental classes and test severity.
• EN 301 489-1 and EN 301 489-4 - EMC requirements for radio equipment and fixed radio links.
• EN 301 215-3 - antenna characteristics for MWS antennas.
• EN 301 390 - spurious emissions and receiver immunity.
• EN 300 132-1 and EN 300 132-2 - power supply interface characteristics.
• ITU-T G.810, G.812, G.823, G.813, G.825 - synchronization principles and timing tolerances.
• ITU-T G.703, G.704, G.707, G.957, I.413, and the I.432 series - common digital and B-ISDN interface references.

The document includes Figure 1 for the reference network architecture and Figure 2 for the RF block diagram, which help readers map system roles and measurement reference points. Table 1 lists commonly used standardized interfaces, from analogue subscriber interfaces to digital, ISDN, LAN, ATM, and B-ISDN interfaces.

Annex A gives intra-block minimum requirements, including spectrum masks, BER versus Receiver input Signal Level (RSL), and co-channel and adjacent-channel interference criteria. Annex B summarizes the EIRP spectral density limits and the block-edge mask used for coordination between adjacent blocks. Annex C provides a matched receiver block-edge selectivity mask, and Annex D shows an example ATPC method for the uplink direction.
