Technical Summary of Hiperlan
Overview:
The HIPERLAN/1 standard defines part of the bottom two layers of the Open System Interconnection (OSI) model, namely layer 1 Physical Layer, and layer 2 Data Link Layer (DLC). Within the DLC layer, only the medium access control sub-layer (MAC) is specific to HIPERLAN.
frequency: 5150-5250 MHz (capability to extend to 5300 MHz where permitted by local regulation)
bit rate: 25 Mbit/s
HIPERLAN/1 can operate on five different channels, three of those for the lower 100 MHz of the band and the upper two within the upper 50 MHz of the band. Facilities are provided so that HIPERLAN equipment cannot illegally use the two upper channels of the 5 GHz band in countries where they are not authorized.
Standards:
- CEPT Recommendation T/R 22-06:
- permits the operation of HIgh PErformance Radio Local Area Networks (HIPERLANs) in the 5,15 to 5,30 GHz and 17,1 to 17,3 GHz frequency bands.
- ETSI Technical Report (ETR 069)
- describes the services and facilities that must be supported within a HIPERLAN sub-system. It also provides some arguments for the choices made for HIPERLAN, in terms of market needs and potential applications.
- ETSI Technical Report (ETR 133)
- describes the HIPERLAN system definition and the general architecture, in terms of functional organization of a HIPERLAN sub-system.
- ETS 300 836-(1-4) (ed.1)
- specifies Type 1 Conformance Testing, including Radio Type Approval and Radio Frequency (RF) - Conformance Test Specification, Protocol Implementation Conformance Statement (PICS) - performance specification, Test Suite Structure and Test Purposes (TSS&TP) specification, and Abstract Test Suite (ATS) specification
- ETS 300 652 (Ed.1)
- 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.
- Separate ETSI standards address other types of HIPERLAN systems.
