scope:

The present document applies to the HIPERLAN/2 air interface with the specifications of layer 1 (physical layer), following the ISO-OSI model. HIPERLAN/2 is confined to only the radio access system consisting of the physical (PHY) layer and DLC layer, which are core network independent, and the core network specific Convergence sublayers. For managing radio resources, association and connection control, the radio link control protocol is applied which uses the transmission services of the DLC layer. The interworking with layers at the top of the radio subsystem is handled by Convergence layers above the DLC layer.

The present document defines the radio aspects like channel coding, interleaving, scrambling, modulation, radio transmission and reception.

The Scope of the specification is as follows:

• it gives a description of the physical layer for HIPERLAN/2;

• it identifies those performance requirements needed to meet regulatory rules and service quality targets;

• it specifies the transmission scheme in order to allow interoperability between equipment developed by different manufacturers. This is achieved by describing the signal processing at the transmitter side, while the processing at the receiver side is left open to different implementation solutions.

The present document does not address the requirements and technical characteristics for type approval and conformance testing. These are covered by separate documents.
