SIST ETS 300 652:1999 is the Slovenian adoption of ETS 300 652 Edition 1 from ETSI. It specifies the functional specification for HIgh PErformance Radio Local Area Network (HIPERLAN) Type 1, including the MAC, CAC and physical layer behavior for high-performance radio local area networks. It is aimed at engineers, integrators, quality teams and buyers who need to understand how HIPERLAN Type 1 equipment is organized and what it is expected to support.

What does SIST ETS 300 652:1999 specify?

SIST ETS 300 652:1999 specifies the technical characteristics, operating modes and management facilities for HIPERLAN Type 1 radio LAN equipment in the frequency bands identified by CEPT Recommendation T/R 22-06. It covers equipment designed for instantaneous terminal data rates of 20 Mbit/s and system densities of 100-1000 Mbit/s/hectare/floor, and it is written to support both portable and fixed terminals.

The standard confines HIPERLAN Type 1 to the Physical layer and the Medium Access Control part of the Data Link layer in the OSI model. Higher-layer protocols are needed for a complete system, but they are outside the scope of this document. The scope also states that type approval and conformance testing are handled in a separate HIPERLAN ETS, and that other HIPERLAN types are covered by separate ETSI standards.

The document is organized as follows:

• Clause 1 - Scope
• Clause 2 - Normative references
• Clause 3 - Definitions, abbreviations and symbols
• Clause 4 - Overview
• Clause 5 - HIPERLAN MAC service definition
• Clause 6 - HIPERLAN MAC protocol specification
• Clause 7 - HIPERLAN CAC service definition
• Clause 8 - HIPERLAN CAC protocol specification
• Clause 9 - Physical layer
• Clause 10 - HIPERLAN enhancement unit
• Clause 11 - Conformance

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

SIST ETS 300 652:1999 defines how HIPERLAN Type 1 equipment exchanges data, accesses the channel, manages power use and structures its protocol data units. For implementers, the key point is that the standard is not just a radio description - it also fixes the service model, addressing rules, access behavior and message formats that devices must follow.

MAC service and addressing

Clause 5 defines the HIPERLAN MAC service as a connectionless data transfer service between MSAPs (MAC Service Access Points). An MSDU can be sent to one destination or a group destination in one service access, with user priority and MSDU lifetime as key service parameters. In practice, this means upper layers can hand data to the MAC without building a connection, but they must still decide how urgent the data is and how long it remains valid.

The standard uses 48-bit LAN MAC addresses for MSAP-addresses. Individual addresses may be used as source or destination addresses, while group addresses are used only as destination addresses. Clause 5 also defines HMQoS parameters - user priority, MSDU lifetime and residual MSDU lifetime - so implementations need to preserve timing-related service information across the transfer.

Clause 5 also defines the HIPERLAN look-up service. An HMS-user can query nearby HIPERLANs and collect HIPERLAN information during a limited collection interval. In practice, this supports discovery and dynamic access planning.

MAC protocol functions

Clause 6 sets out the MAC protocol and states a maximum MSDU size of 2 383 octets. It specifies five main MAC functions:

• HIPERLAN look-up
• power conservation
• user data transfer
• routeing information maintenance
• HMPDU transfer

This matters because a device may not need every function, but it must implement the functions required by its role and by clause 11.

Power conservation is based on recurring individual-attention and group-attendance patterns. A p-saver declares an individual-attention pattern in IP-HMPDU, and a p-supporter declares a group-attendance pattern in GP-HMPDU. The timing elements are pattern offset, pattern period and practice interval. In practice, this lets devices sleep and wake in a predictable way so they can save power without breaking scheduled communication.

The MAC protocol also defines how HMPDUs are selected for transmission. When several are waiting, the protocol chooses first by highest channel access priority and then by shortest normalized residual HMPDU lifetime. This is important for engineers because urgency and expiry are part of the scheduling logic, not just traffic volume.

CAC service and channel access

Clause 7 defines the HIPERLAN CAC service, which works through HCSAPs (HIPERLAN CAC Service Access Points). HCSDU transfer is also connectionless, but unlike the MAC service it is guided by NPMA channel access cycles and is always acknowledged by the provider with a transfer status. The user can request a channel access priority, and the transfer control service can tell the user when a transfer may be attempted.

Clause 8 defines EY-NPMA (Elimination-Yield Non-Pre-emptive Priority Multiple Access), the channel access method used by HIPERLAN Type 1. EY-NPMA operates through prioritization, elimination, yield and transmission phases. This matters in practice because channel access is coordinated by a defined contention process rather than by a simple carrier-sense rule.

Clause 8 also defines channel permission behavior. There are five channels, numbered 0 to 4. Channels 0, 1 and 2 are mandatory default channels, while channels 3 and 4 are non-default channels whose availability depends on national administrations. If a non-default channel has not been permitted, an HC-entity must not transmit on it and must ignore received HCPDUs there except CP-HCPDUs.

Physical layer behavior

Clause 9 covers the physical layer tasks and constraints. It includes modulation and demodulation, burst and bit synchronization, transmission and reception on specific carrier frequencies, forward error correction, received signal strength measurement, clear channel assessment and defer threshold maintenance. In practice, this tells a designer what the radio front end and PHY control logic must do.

The physical layer defines transmitter and receiver equipment classes A, B and C, with only certain class combinations permitted in one HIPERLAN device. It also specifies clear channel assessment based on received signal strength only, with an optional adaptive defer threshold. For implementation, that means channel-idle decisions are based on measured signal level, not on a more complex sense algorithm.

Clause 9 also fixes the main modulation choices: GMSK with BT = 0,3 for high bit rate transmission and FSK for low bit rate transmission. It includes radio power limits, unwanted emission limits, receiver spurious emission limits, and the signal strength mapping used for RSSI/SLN reporting. These details matter when aligning hardware, calibration and compliance measurements.

What terms does SIST ETS 300 652:1999 define?

• High Performance Radio Local Area Network, Type 1 (HIPERLAN) - a radio local area network in which all nodes share a single communication channel.
• Channel Access Control (CAC) - the sublayer between the MAC sublayer and the physical layer in the HIPERLAN reference model.
• Elimination-Yield Non-Pre-emptive Priority Multiple Access (EY-NPMA) - the specific NPMA method used to access the HIPERLAN channel.
• MAC Service Access Point (MSAP) - the service access point through which the MAC service is offered between HMS-user and HMS-provider.
• HCSAP - the HIPERLAN CAC Service Access Point through which the CAC service is offered between HCS-user and HCS-provider.
• MAC Service Data Unit (MSDU) - the data unit transferred by the HIPERLAN MAC service.
• HCSDU - the data unit transferred by the HIPERLAN CAC service.
• HMQoS / HCQoS - the HIPERLAN MAC / CAC quality of service parameters used to express priority and lifetime or transfer behavior.

Who uses SIST ETS 300 652:1999?

This standard is used by radio equipment designers and telecom engineers who need to build HIPERLAN Type 1 terminals, access functions and radio behavior to a common specification. It is also relevant to firmware and protocol developers who implement MAC and CAC procedures, addressing, routing support, acknowledgements and protocol data unit encoding.

Quality managers and test teams use it to check whether implemented behavior matches the defined service model, protocol structure and physical-layer limits. Network planners and system integrators use it when deciding how HIPERLAN devices handle discovery, power saving, channel permission and channel access priorities. Buyers and technical reviewers can use it to confirm that a product is intended for HIPERLAN Type 1 operation in the specified 5 GHz bands.

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

SIST ETS 300 652:1999 identifies itself as identical to ETS 300 652 Edition 1.

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

The body of the standard contains service definitions, protocol definitions and physical-layer rules, with procedures laid out in many numbered subclauses. It includes structure and encoding rules for HMPDUs and HCPDUs, including field definitions, transfer functions and acknowledgement behavior.

It also contains tables for predefined values, such as holding times, HMPDU lifetimes and protocol priorities, together with tables for permissible transmitter and receiver class combinations, signal strength mapping and emission limits. Figures show the reference models, communication model, recurring power-saving patterns and EY-NPMA access behavior.

Annex A gives an example HIPERLAN MIB, which is useful for management-oriented implementation work. Annex B places HIPERLAN in the OSI management framework and explains how OSI Systems Management and LAN/MAN Management relate to HIPERLAN managed objects. Annex C provides the bibliography.

1 Scope
CEPT Recommendation T/R 22-06 [1] permits the operation of high speed radio local area networks in
the 5,15 to 5,30 GHz and 17,1 to 17,3 GHz frequency bands. These types of radio networks are referred
to as HIgh PErformance Radio Local Area Networks (HIPERLANs).
This ETS specifies the technical characteristics of HIPERLAN Type 1 that operates in the 5,15 to
5,3 GHz frequency band and that uses Non-Pre-emptive Priority Multiple Access (NPMA) as the channel
access method.
HIPERLAN Type 1 is confined to the lowest two layers of the Open Systems Interconnection (OSI) model:
the Physical Layer and the Medium Access Control (MAC) part of the Data Link Layer. Functions of higher
layers are required for operation and interworking of a complete systems. These higher layers are outside
the scope of this document.
This ETS does not address the requirements and technical characteristics required for type approval and
conformance testing. These are covered in a separate HIPERLAN ETS.
Separate ETSI standards address other types of HIPERLAN systems.
