SIST EN 300 408 V1.3.1:2003 is the Slovenian standard that is identical to ETSI EN 300 408 V1.3.1 for fixed radio systems around 58 GHz. It specifies minimum performance requirements for point-to-point equipment that carries digital signals and analogue video signals in the 57 GHz to 59 GHz band when coordinated frequency planning is not required. The document separates equipment into Class A and Class B and sets requirements for channel selection, spectrum use, transmitter limits, interfaces, environmental conditions, and EMC.

What does SIST EN 300 408 V1.3.1:2003 specify?

SIST EN 300 408 V1.3.1:2003 specifies minimum performance requirements for terrestrial fixed service radiocommunications equipment operating in the 58 GHz band for uncoordinated use. It is written for point-to-point equipment and distinguishes between digital systems and wideband analogue systems.

The scope also makes two practical limits clear. Test procedures and test conditions are handled in EN 301 126-1, and safety is outside the ETSI mandate, with EN 60950 named for compliance purposes.

The document is organized into:

• Clause 1 - Scope
• Clause 2 - References
• Clause 3 - Symbols and abbreviations
• Clause 4 - General characteristics
• Clause 5 - Parameters for digital systems
• Clause 6 - Parameters for wideband analogue systems
• Annexes A to E

What are the key requirements of SIST EN 300 408 V1.3.1:2003?

The main requirements focus on frequency use, interference avoidance, transmitter limits, and reference interfaces. In practice, these are the points that determine whether a link can be installed, tested, and declared compliant.

Frequency band, channeling, and channel selection

SIST EN 300 408 V1.3.1:2003 applies to the 57 GHz to 59 GHz band. Channel arrangements follow CEPT/ERC Recommendation 12-09 with 50 MHz or 100 MHz rasters, and Annex A gives a convenient overview of the channel plan.

For Class A equipment, RF-channel selection is mandatory. The terminal must measure interference during installation and only transmit on an unoccupied channel, which matters because the standard uses this process to protect existing links from new ones.

Interference limits and frequency agility

SIST EN 300 408 V1.3.1:2003 defines an interference-avoidance limit for Class A equipment and requires calibration with a CW test signal at the antenna port. Annex D explains the reasoning behind the limit and the channel-selection threshold.

Frequency agility is optional, but if implemented it must be able to switch RF channels automatically after unacceptable interference and must also be defeatable. Manufacturers also declare the interference criteria they use, so buyers and test labs know how the feature behaves.

Transmitter, spectrum, and emissions

For both digital and analogue systems, the transmit power at point D' is limited and EIRP is capped at 15 dBW. The standard also gives separate spectrum-mask requirements for 100 MHz and 50 MHz channels, and the masks must be met with all baseband options in use.

Spurious emissions are controlled by reference to CEPT/ERC Recommendation 74-01. Radio frequency tolerance is tighter for digital systems than for wideband analogue systems, so the equipment class affects oscillator stability and test expectations.

Interfaces, environment, and power

If a standard baseband interface is provided, it shall comply with an ETSI-recognized ITU-T interface such as G.703 for Class A conformance testing. The manufacturer must declare whether a standard interface is provided.

Environmental conditions follow EN 300 019 classes for indoor and outdoor use, EMC follows EN 300 385 or EN 301 489-1 plus EN 301 489-4, and the power supply must fit ETS 300 132-1 and ETS 300 132-2. In practice, these clauses tell the installer what site conditions and supply arrangements the equipment is designed for.

What terms does SIST EN 300 408 V1.3.1:2003 define?

• Equivalent Isotropically Radiated Power (EIRP) - the radiated power level used to limit how strongly the transmitter can illuminate the link.
• High Density Fixed Service (HDFS) - the Class A application area, typically for public network connections.
• Frequency Division Duplex (FDD) - a duplexing method named in Annex D and Annex A when discussing coexistence.
• Time Division Duplex (TDD) - a duplexing method named in the same coexistence discussions.
• Bit Error Ratio (BER) - the error measure used in the interference and availability background.
• Radio Frequency (RF) - the part of the system dealing with the microwave carrier and channel selection.
• Noise Figure (NF) - a receiver parameter used in Annex D when explaining the channel-selection threshold.

Who uses SIST EN 300 408 V1.3.1:2003?

Manufacturers of fixed radio link equipment use SIST EN 300 408 V1.3.1:2003 to design digital and analogue point-to-point systems for the 58 GHz band. Network operators and planners use it when they need short links in public networks or private networks without coordinated frequency planning.

Test laboratories use it for conformance testing, especially around transmitter power, spectrum masks, spurious emissions, and RF-channel selection behavior. Regulators use Annex C system type codes and Annex A channel guidance when setting local procedures or band plans.

What changed in SIST EN 300 408 V1.3.1:2003 from the previous edition?

This edition follows ETS 300 408 V1.2.1 and mainly introduces a different spectrum mask for systems designed for 50 MHz channel separation. The scope also notes modified antenna requirements and editorial changes to improve clarity.

Which standards are used with SIST EN 300 408 V1.3.1:2003?

The document relies on several named standards and recommendations to fill in the technical details:

• EN 301 126-1 - conformance testing definitions, general requirements, and test procedures
• EN 300 019 - environmental classes and environmental test severities
• EN 301 489-1 and EN 301 489-4 - EMC requirements for radio equipment and fixed radio links
• EN 300 833 - antenna radiation pattern requirements
• ETS 300 132-1 and ETS 300 132-2 - power supply interface requirements
• CEPT/ERC Recommendation 12-09 - 57 GHz to 59 GHz channel arrangement
• CEPT/ERC Recommendation 74-01 - spurious emissions
• ITU-T G.703 - hierarchical digital interface characteristics
• ITU-T G.821 and G.826 - error performance objectives
• ITU-R F.697 and F.1493 - availability and performance objectives for digital radio-relay links
• ITU-R P.676 - atmospheric attenuation data
• ITU-T O.151 - error performance measuring equipment
• EN 60950 - safety of information technology equipment

What does the SIST EN 300 408 V1.3.1:2003 document contain?

The document contains a system block diagram with measurement reference points, spectrum-mask figures for 50 MHz and 100 MHz channels, and a table of analyzer settings for spectrum measurements. It also includes a normative table of system type codes for regulatory procedures.

Annex A adds channel-arrangement and antenna-alignment guidance, which is useful during installation so a new link does not start on an occupied channel. Annex D explains why the interference threshold is set the way it is, which helps engineers justify channel selection and interference planning.

1 Scope The present document specifies the minimum performance requirements for terrestrial fixed service radiocommunications equipment operating in the 58 GHz frequency band which do not require co-ordinated frequency planning. The frequency band is proposed to be used by various technologies for uncoordinated use of the band. It also benefits from the high and stable atmospheric attenuation which suppresses efficiently distant interferers (about 10 dB/km to 15 dB/km at sea level, refer to ITU-R Recommendation P.676 [17]). For the purposes of the present document two equipment classes are specified depending on the network requirements: - Class A: Digital equipment for High Density Fixed Service (HDFS) applications typically connected to public networks, which apply the RF-channel selection procedure (see clause 4.1.3), error performance and availability requirements (see clause 5.2). - Class B: Equipment without requirements for quality of service, typically private network connections. Typical applications for Class A equipment are e.g. interconnection between cellular networks where there, in some cases, is a need for short length connections (up to about 500 meters). The RF channel selection procedure shall be used to protect existing systems from a new system being commissioned. However, the channel selection procedure may not guarantee interference free installation or operation in all cases due to limitations in the procedure with respect to the variety of systems. Typical applications for Class B equipment are in private networks, such as video surveillance systems. This new version of this EN, introduces a different spectrum mask for systems designed for 50 MHz channel separation. While considered more convenient from the point of view of easy and cost effective design, the new mask is considered equivalent to the previous one from the point of view of spectrum efficient usage. Therefore, from the technical point of view, for compliance to article 3.2 of R&TTE Directive [19], systems that have already been assessed against the previous version of the present document should not be necessarily reassessed against this new version. The present document does not contain aspects related to test procedures and test conditions, however they are to be found in EN 301 126-1 [7]. Safety aspects are outside the mandate of ETSI and they will not be considered in the present document. However compliance to EN 60950 [18] will be required to comply with Directive 1999/5/EC [19]. Technical background for the parameters and requirements referred in the present document may be found in TR 101 036-1 [16]. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document. • References are either specific (identified by date of publication and/or edition number or version number) or non-specific. • For a specific reference, subsequent revisions do not apply. • For a non-specific reference, the latest version applies.
