High Performance Radio Metropolitan Area Network (HiperMAN)
HiperMAN stands for High Performance Radio Urban Area Network and is the standard made by the Western European Telecommunications Standards Institute Broadband Radio Access Networks group to offer a Wi-fi network communication in the 2.11 GHz bands across Europe and other states which follow the ETSI standard.
HiperMAN is a EU alternative to WiMAX (or the IEEE 802.16 standard) and the Korean technology WiBro. HiperMAN is targeting predominantly for providing broadband Wireless Web access, while covering a gigantic geographic area. The standardizing focuses on broadband solutions optimised for access in frequency bands below eleven GHz (principally in the 3.5 GHz band). HiperMAN is optimised for packet switched networks, and supports fixed and nomadic applications, essentially in the home and small enterprise user environments. HiperMAN will be a broadband fixed wireless access system operating at radio frequencies between 2 GHz and eleven GHz.
The HiperMAN technology is used for Fixed Wireless Access provisioning to SMEs and residences using the basic MAC (DLC and CLs) of the IEEE 802.16-2001 standard. It's been developed in extraordinarily close cooperation with IEEE 802.16, such the HiperMAN standard and a subset of the IEEE 802.16a-2003 standard will interoperate neatly. HiperMAN is actually capable of supporting ATM, though the target is on IP traffic. It offers assorted service classes, full service quality, fast connection control management, powerful security, fast modification of coding, modulation and broadcast power to propagation conditions and is actually capable of non-line-of-sight operation.HiperMAN enables both PTMP and Mesh network configurations. HiperMAN also supports both FDD and TDD frequency grants and H-FDD terminals. All this is achieved with a minimal number of options to clarify implementation and interoperability.
Features of HiperMAN: - The primary feature of the HiperMAN system to distinguish it from competitive exclusive systems is the level of interoperability that's offered. This will lead on to larger approval of radio based broadband access networks than with the exclusive systems which are being brought to the market. This advantage can only be realised if suitable broad conformance test directions are available just after the clobber standard is finished.
The HiperMAN specs are being developed by ETSI technical board Broadband Radio Access Networks (BRAN). These are developed in cooperation with IEEE 802.16, such the HiperMAN standard and a subset of the IEEE 802.16a-2003 standard will interoperate seamlessly. ETSI BRAN working with a WiMAX Forum, the industry forum promoting IEEE802.16 / HiperMAN technology and contributing experience to the verification scheme which will assure the interoperability of IEEE802.16 / HiperMAN devices.
