SIST ETS 300 652:1999/A2:1999 is the Slovenian standard identical to ETS 300 652/A2 Edition 1. It is Amendment 2 to ETS 300 652 from the European Telecommunications Standards Institute (ETSI), and it updates the functional specification for Radio Equipment and Systems (RES) HIgh PErformance Radio Local Area Network (HIPERLAN) Type 1. Engineers use it to check the timing and frequency stability of HIPERLAN node implementations.

What does SIST ETS 300 652:1999/A2:1999 specify?

SIST ETS 300 652:1999/A2:1999 specifies a targeted amendment to the ETS 300 652 (1996) functional specification for HIPERLAN Type 1. It is not a full rewrite of the base standard - it adds one technical change to the existing document.

The document is organized as front matter, a foreword, the amendment text, and document history. The technical change is directed to subclause 9.7.3 of the base standard, so users apply this amendment together with ETS 300 652 (1996).

What are the key requirements of SIST ETS 300 652:1999/A2:1999?

The amendment adds one main technical requirement, and that requirement affects how a HIPERLAN node is built and checked.

• Subclause 9.7.3 adds a synchronization limit for the frequency sources used for RF generation and for deriving modulation clocking. In practice, designers need the transmit timing sources to stay closely aligned, so the node does not drift outside the allowed frequency relationship.
• The synchronization requirement applies to both high rate transmission and low rate transmission. That means the timing architecture has to work across the full operating behavior of the node, not just one mode.
• The requirement applies within a HIPERLAN node. For implementation and test, the focus is on the internal radio design - oscillators, reference distribution, and clock generation - rather than only on over-the-air behavior.
• Because the amendment is placed in subclause 9.7.3, compliance work should use the base standard plus this added text. In practice, a lab or quality team would verify that the node’s RF and modulation timing chain meets the stated synchronization tolerance.

What terms does SIST ETS 300 652:1999/A2:1999 define?

• RES - Radio Equipment and Systems, the ETSI family name used in the title for radio communications standards.
• HIPERLAN - HIgh PErformance Radio Local Area Network, the radio LAN technology covered by the base standard and this amendment.
• Type 1 - the specific HIPERLAN profile addressed by the functional specification.
• ETSI - European Telecommunications Standards Institute, the body that produced the amendment.
• BRAN - Broadband Radio Access Networks, the ETSI project named in the foreword as the origin of this amendment.
• RF - radio frequency, the part of the node responsible for generating the transmitted radio signal.
• ppm - parts per million, the frequency tolerance unit used in the synchronization requirement.

Who uses SIST ETS 300 652:1999/A2:1999?

Radio equipment designers use this amendment when they define the clocking and frequency architecture of a HIPERLAN Type 1 node. Test laboratories and conformance teams use it when checking that the implementation meets the synchronization rule in the updated clause.

Quality managers and technical buyers use it to confirm that a supplier’s HIPERLAN equipment is designed against the correct version of the functional specification. Standards engineers use it to keep the amendment linked to the base ETS 300 652 document during verification and procurement.

What changed in SIST ETS 300 652:1999/A2:1999 from the previous edition?

SIST ETS 300 652:1999/A2:1999 modifies ETS 300 652 (1996) by adding a synchronization requirement in subclause 9.7.3. The added text requires the frequency sources for RF generation and modulation clocking in a HIPERLAN node to remain synchronized within a 2 ppm tolerance for both high rate and low rate transmission.

The document history identifies this as Amendment 2 to the First Edition.

Which standards are used with SIST ETS 300 652:1999/A2:1999?

• ETS 300 652 (1996) - the base functional specification that this amendment modifies and that readers must use together with the amendment.

What does the SIST ETS 300 652:1999/A2:1999 document contain?

The document contains the amendment notice, the ETSI foreword, and the specific change to subclause 9.7.3. It also includes transposition dates and document history, which help users track adoption and publication status.

Its technical content is a short insertion that updates the base standard’s requirements for node frequency-source synchronization. For readers, the useful part is the clause reference and the added timing requirement, which can be carried into design reviews, test plans, and compliance checks.
