`
`Foreword
`
`This Technical Report (TR) has been produced by ETSI Project Broadband Radio Access Networks (BRAN).
`
`The present document describes the requirements and architectures that are applicable to High PE1‘formance Radio
`Local Area Network (HTPERLAN) Type 2. HTPERLAN Type 3 has been subsumed by licence exempt HTPERACCESS
`[2fj. HTPERLAN Type 4 has been renamed to HTPERLINK. The latter two are described in separate reports.
`
`Introduction
`
`Wireless networks have enjoyed an increased demand from the general public as well as from business and other
`professional users.
`
`Wireless networks in existence today range from cellular phones to high speed digital networks supporting high speed
`computer communications. They operate in licensed as well as in unlicensed frequency bands.
`
`At the same time, wired telecommunications networks have shown a remarkable evolution towards higher transmission
`rate and support for multi-media applications rather than simple voice oriented services.
`
`ETSI has recognized the trend towards better and faster wireless networking demands from all kinds of users. Working
`with the CEPT resulted, in the period 1990 through 1992, in spectrum designations in the 2,4 GHz TSM band, in the
`5,2 GHZ band and in the l7,'l GHz band to allow the development ofa variety of standards for wireless networks. The
`2,4 GHz TSM band was intended for medium speed “wide band data systems using spread spectrum techniques". The
`latter two bands were assigned to HIPERLANs, a collective reference to High Performance Radio Local Area Networks.
`ETSI has identified the need for a family of HIPERLAN standards that together support a wide variety of usage
`scenarios and applications.
`
`HIPERLAN Type 1 provides an ISO/IEC 8802-1 [5] compatible wireless local area network.
`
`HIPERLAN Type 2 is intended to provide short range broadband wireless access to Internet Protocol (IP),
`Asynchronous Transfer Mode (ATM) networks and Universal Mobile Telecommunications System (UMTS).
`
`HIPERLAN Type 1 operates in the 5,2 GHZ licence exempt band; Type 2 is intended to operate in the 5,2 GHZ band
`and other 5 GHZ bands (note 1); HIPERLINK is intended to operate in 17,2 GHZ band. The CEPT has designated
`100 MHz of spectrum in the 5 GHZ band for HIPERLANs with a further 50 MHz available at the discretion of national
`administrations and 200 MHz in the 17 GHZ band. (See CEPT Recommendation T/R 22-06 [1] and ERC Decision
`96/03 [6]). Because the current allocation in the 5,2 GHz band is expected not to be sufficient for the projected needs of
`users and their applications, ETSl has initiated discussions with CEPT aimed at making more spectrum available in this
`range.
`
`NOTE 1: Other frequency bands around 4 GHZ to 6 GHZ may be used on a licensed basis.
`
`NOTE 2: The FCC has allocated in the USA 300 MHz of spectrum at 5 GHZ band referred to as the U-NII
`(Unlicensed National lnformation lnfrastructure) bands, in which HTPERLAN devices may be operated.
`
`Developments in other types ofwireless networks have increased the scope and potential applications of such networks.
`A primary example is UMTS (or IMT-2000 as it is known outside Europe). UMTS, in its various forms, supports a wide
`

`
`range ofcommunications services, from cordless services to \vide area cellular services. The range of bit rates, with a
`maximum of2 Mbit/s, supported by UMTS is geared primarily towards voice and low quality video as well as data
`services. However, because of spectrum limitations as well as for economic reasons, UMTS will not be able to meet the
`bandwidth demands oftrue, high resolution multi-media communications. These require bit rates in the range of
`10 Mb/s. The required bandwidth is not available in the planned UMTS frequency range and it is likely that the cost to
`users of such bandwidth would be excessive. Furthermore, it is not clear that there exists demand for such high speed
`services beyond the premises ofa business or other organization. On premises, short range wireless networks that do not
`share spectrum with UMTS are much more attractive and flexible as a solution to multi-media wireless networking.
`HIPERLANS fill that need. The following figure clarifies the relationship between HIPERLANS and UMTS:

`
`it should be noted that the above does indicates that users may well perceive benefits form being able to access UMTS
`based services from HIPERLAN compatible devices and vice versa.
`
`To date ETSI has published two standards: ETS 300 328 [3] which provides the type approval requirements for data
`networks operating in the 2,4 GHZ ISM band and ETS 300 652 [2] which provides a functional specification of high
`speed ISO 8022 compatible wireless networks.
`
`The present document has been written to assist the ETSI membership as well as the potential users of standards for high
`speed wireless data systems in understanding the applications and concepts that underlie the standards for HIPERLAN
`Type 2.
`
`As this understanding develops during the writing ofthe actual standards, the present document is likely to require
`change. Therefore, it should be treated as a living document rather than a definitive text.

`
`Scope
`
`The scope of the present document is limited to the requirements and architectures for HIPERLAN Types 2.
`HIPERLAN Typel is addressed by ETS 300 652 [2] and its related Conforniance Test Specifications, [2a], [2b], [2c]
`and [2d]. HIPERLINK will be described in a TR produced by BRAN.
`
`The requirements address subjects like applications, traffic volumes and traffic pattems that underlie the projected
`spectrum requirements as well as the chosen architectures. The architectures address the communications layer models
`as well as the Reference models that identify the key intcrfaccs subject to standardization.
`
`The architectures developed in the present document are intended to delineate the boundaries between HIPERLAN
`standards and standards for networks in which HIPERLANs may be used as subsystems or components.
`
`Scope of standardization
`
`The scope ofthe standards for HIPERLAN Types 2 is limited to the air interface specifications, the Data Link Control
`(DLC) layer specifications, the specifications of the management functions and the interworking functions. The DLC
`layer specification includes a specification of tl1e services to be provided.
`
`Tl1e ETSI HIPERLAN/2 standards specify subsystems up to and including the DLC Layer. Interworking functions will
`be specified in liaison with other relevant technical standardization bodies.

`
`HIPERLAN Type 1, Wireless 8802 Local Area Networks
`
`HIPERLAN Type l (HIPERLAN/I) is a wireless local area network that is ISO/IEC 8802-I [5] compatible. It is
`intended to allow high performance wireless networks to be created, without existing wired infrastructure. Multiple
`I-IIPERLANS can co-exist in the same geographical area with equitable bandwidth sharing without co-ordination
`between them. In addition HIPERLAN Type 1 can be used as an extension ofa wired local area network.
`
`HIPERLAN/l offers unconstrained connectivity based on directed one-to-one communications as well as one-to-many
`broadcasts. The channel provides both self configurability and flexibility of use thanks to a distributed channel access
`(EY-NPMA) and standardized forwarding feature.
`
`The HIPERLAN/l Functional Specification is given in ETS 300 652 [2].

`
`HIPERLAN Type 2, short range wireless access to IP, ATM
`and UMTS networks
`
`HIPERLAN Type 2 (HIPERLAN/2) is intended to provide local wireless access to IP, ATM and UMTS infrastructure
`networks by both moving and stationary terminals that interact with access points which, in turn, usually are connected
`to an IP, ATM or UMTS backbone network. A number ofthese access points will be required to service all but the
`smallest networks of this kind and therefore the wireless network as a whole shall suppott hand-overs of connections
`between access points. Further, such a wireless access network shall be able to provide the Quality of Service (QoS),
`including required data transfer rates, that users expect from a wired IP or ATM network.
`
`4.3
`
`HIPERACCESS, remote wireless access to IP and ATM
`
`networks
`
`HIPERACCESS provides outdoor, high speed (25 Mbit/s typical data rate) radio access, it provides fixed radio
`connections to customer premises and is capable of supporting multimedia applications. (Other technologies such as
`HIPERLAN/2 might be used for distribution within the premises.) HIPERACCESS will allow an operator to rapidly roll
`out a wide area broadband access network to provide connections to residential households and small businesses.
`However, HIPERACCESS may also be of interest to large organizations wishing to serve a campus and its surroundings
`and to operators oflarge physical facilities such as airports, universities, harbours etc.
`
`4.4
`
`HIPERLINK, wireless interconnection
`
`interconnecting high data rate sources such as (access) networks requires high bit rates and large channel capacities.
`HIPERLINK provides point-to-point interconnection at very high data rates, e.g. up to 155 Mbit/s over distances up to
`150 m.

`Requirements
`
`This clause deals with the general requirements that underlie the development of the HIPERLAN standards for wireless
`broadband access.

`
`Application environments
`
`The following subclauses describe a number of application environments. The common denominator of these
`environments is that:

`
`they are used in a geographically limited area;
`
`they support multimedia services.

`
`Types of HIPERLAN application environments
`
`Domestic Premises Network (DPN) environment
`
`The DPN environment covers the home and its immediate vicinity; it typically includes a localized radio extension to a
`broadband network. It is characterized by spot coverage areas, perhaps individual cells, one per home or building.
`Support for mobility beyond the coverage area is outside the scope of the present document.
`
`Business Premises Network (BPN) environment
`
`The BPN environment covers a network covering eg. a company area, university campus hospital, industrial premises,
`airports, train stations, etc. It may offer access, switching and management functions within an arbitrary large coverage
`area serviced by multi-cellular wireless communications facilities. Thus, functions like handover and paging may be
`necessary within this environment.

`
`Types of networks
`
`HIPERLANs may be used in a number ofways, for example:
`
`Wireless Access to Public Network
`
`l-IIPERLAN Type 2 may be used to gain access to a public network, for example, to provide Telepoint services.
`
`Wireless Access to Private Network
`
`HIPERLANs may be used to gain access to a private network, for example, business premises or campus networks.
`
`Temporary Network
`
`HIPERLANs may be used to create temporary networks, independent of an established wired local network. Such a
`network may be used semi-permanently, as an alternative for a wired network, and for ad-l1
