The information pertaining to these essential IPRs, if any, is publicly available for ETSI members and non-members, and can be found in SR 000 314: "Intellectual Property Rights (IPRs); Essential, or potentially Essential, IPRs notified to ETSI in respect of ETSI standards", which is available from the ETSI Secretariat. Latest updates are available on the ETSI Web server (http://www.etsi.org/ipr). Pursuant to the ETSI IPR Policy, no investigation, including IPR searches, has been carried out by ETSI. No guarantee can be given as to the existence of other IPRs not referenced in SR 000 314 (or the updates on the ETSI Web server) which are, or may be, or may become, essential to the present document. Foreword This Technical Report (TR) has been produced by ETSI Project Broadband Radio Access Networks (BRAN). The present document describes the top-level functional overview of HIPERLAN/2 systems. Separate ETSI documents provide details on the physical layer, data link layer, the convergence layers, network management, and the conformance test requirements defined for HIPERLAN/2. Introduction The purpose of the present document is to help system integrators, prospective users and spectrum management authorities to obtain a broad view of the scope and content of the HIPERLAN/2 Technical Specifications. Subsequent clauses of the present document develop the following topics: Clause 4: describes the use and applications of the HIPERLAN/2 systems; Clause 5: describes the primary spectrum utilization factors of the HIPERLAN/2 systems; Clause 6: describes the services and functions of the Data Link Control (DLC) Layer and the Physical (PHY) Layer of the HIPERLAN/2 systems; Clause 7: describes the security aspects of the HIPERLAN/2 systems; Clause 8: describes the network management aspects of the HIPERLAN/2 systems. ETSI 5 ETSI TR 101 683 V1.1.1 (2000-02) 1 Scope The basic approach taken by the ETSI project BRAN is to standardize only the radio access network and some of the convergence layer functions to different core networks. The core network specific functions will be left to the corresponding fora (e.g., ATM Forum, IETF and other ETSI projects). This is illustrated in figure 1. Broadband Radio Access Network Core Networks Radio Access Network CL1 TCP/IP Terminal CL2 ATM/B-ISDN Access Terminal CL1..n Radio Entities Subsystem Network CL3 UMTS Air ... ... Interface CLn IEEE 1394 Figure 1: Reference Model The scope of the HIPERLAN/2 Technical Specifications are limited to the air interface, the service interfaces of the wireless subsystem, the convergence layer functions and supporting capabilities required to realize the services. The air interface will be a multi-vendor interoperability interface. Figure 2 illustrates the corresponding terminal stack in a more detailed manner. Core Core Core Network Network Network Network Convergence sublayer HIPERLAN/2 DLC HIPERLAN/2 PHY Figure 2: Terminal view The HIPERLAN/2 Technical Specifications describe the PHY and DLC layers, which are core network independent, and the core network specific convergence layer. It should be noted that to specify a complete HIPERLAN/2 based system, other specifications, e.g. for the Network layer and higher layers are required. These specifications are assumed to be available or to be developed by other bodies. First options are: • packet based networks with support of Ethernet [6],
