HiPERLAN - High Performance Local Area Network

By: Preethi Ramkumar

Meaning of HiPERLAN – “High Performance Local Area Network” is developed by the European Telecommunications Standards Institute, HiperLAN is a set of WLAN communication standards used chiefly in European countries. HiperLAN is similar to the IEEE 802.11 WLAN standards used in the U.S.

There are two types of HiperLAN: HiperLAN/1: provides communications at up to 20 Mbps in the 5 GHz band. HiperLAN/2: provides communications at up to 54 Mbps in the 5 GHz band. Like 802.11, HiperLAN serves to ensure the possible interoperability of different manufacturers' wireless communications equipment that operate in this spectrum.

The HiperLAN standards provide features and capabilities similar to those of the IEEE 802.11 wireless local area network (LAN) standards, used in the U.S. and other adopting countries. HiperLAN/1 provides communications at up to 20 Mbps in the 5-GHz range of the radio frequency (RF) spectrum. HiperLAN/2 operates at up to 54 Mbps in the same RF band. HiperLAN/2 is compatible with 3G (third-generation) WLAN systems for sending and receiving data, images, and voice communications. HiperLAN/2 has the potential, and is intended, for implementation worldwide in conjunction with similar systems in the 5-GHz RF band.

“…IEEE 802.11 standard for WLANs is emerging as a mature standard presenting a well-defined technology that is being adopted by the manufacturers and accepted by the users. Chip sets have been developed according to the IEEE 802.11 standard, making software creativity easier for developing new applications toward expanding the market. The European Telecommunications Standards Institute’s (ETSI’s) RES-10 group has defined another alternative technology, High-Performance Radio LAN version 1 (HIPERLAN I), which is primarily focused on ad hoc networking applications and supports higher data rates. More recently, research around wireless ATM has spread like an epidemic, engaging numerous companies in examining the suitability of yet another alternative standard technology for WWLA." [Worcester Polytechnic Institute]

“…HiperLAN (for High Performance Radio Local Area Network ) is a new high-performance 5GHz radio networking technology, specifically suited for operating in LAN environments. HiperLAN2 is being developed by the European Telecommunications Standardisation Institute (ETSI) Broadband Radio Access Networks (BRAN) project. ” [HiperLAN Resource Center]

“…HiperLAN is a set of wireless local area network (WLAN) communication standards primarily used in European countries. There are two specifications: HiperLAN/1 and HiperLAN/2. Both have been adopted by the European Telecommunications Standards Institute (ETSI). ” [Techtarget]

“…HIPERLAN Type 1 (HIPERLAN/1) is a wireless local area network that is ISO/IEC 8802-1 [5] compatible. It is intended to allow high performance wireless networks to be created, without existing wired infrastructure. Multiple HIPERLANs 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 of a wired local area network. HIPERLAN/1 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.” [Broadband Radio Access Networks (BRAN)]

“…HiperLAN is a wireless LAN designed to transport data between a wireless access point and a terminal at speeds up to 25 Mbit/s. One of the major goals of H/2 standards is interoperability. This can only be achieved by quick, careful and broad conformance test specification.” [Specialist Task Force]
