Session Abstract:The Technical Commitee BRAN (Broadband Radio Access Networks) is responsible for the development of all types of interoperable broadband wireless systems within ETSI (European Telecommunications Standardization Institute).
The main current activities of BRAN include
· HiperMAN technology for frequencies below 11 GHz and non-LOS propagation (based on OFDM/OFDMA), this is a PMP (Point-to-MultiPoint) system optimized for wireless DSL and packet-based core networks, addressing fixed and portable applications. Extensions for mesh networks, adaptive antennas, network management, etc. are under development.
· HiperAccess technology for the 10 – 60 GHz frequency range under LOS conditions (based on single carrier transmission), this is a fixed PMP system optimized for cellular and hot-spot backhauling with very high throughput and spectral efficiency due to comprehensive adaptive concepts.
· Regulatory and spectrum competence center, especially focusing on the 5.0 and 5.8 GHz domains. This includes also co-operation with ITU-R and many other forums around the world.
· Future activities are expected to cover also fixed non-interoperable point-to-point microwave links in all frequency ranges as well as the new class of advanced Gigabit radio LANs.
The first BRAN-compliant networks were deployed in December 2004 in Germany for full commercial usage, using a HiperAccess variant optimized for low-delay point-to-point applications.
Generally, ETSI standards are not restricted to base specifications but include also test specifications serving as basis for certification schemes to ensure interoperability over the air between equipment from different manufacturers.
The development of HiperMAN and HiperAccess systems is performed in close co-operation with
· IEEE 802.16 WirelessMAN to ensure the harmonization of the base standards in order to achieve the goal of a common global wireless infrastructure, and
· the WiMAX forum, where recently a co-operation for the joint development of test specifications was agreed, in order to benefit from the combination of the expertise of the ETSI Protcol and Testing Comptence Center (PTCC) and the promotional and certification strength of WiMAX.
The mutual benefits of these harmonization and co-operation activities are outlined.
The presentation also adresses some regulatory requirements (frequency bands, transmit power, power flux densities, etc.) in order to maximize the throughput of PMP systems.

Speaker: Bernd Friedrichs

Bio: Bernd joined ETSI BRAN standardization in 1998, and since 2002 he has been Chairman of the ETSI BRAN project, comprising the Hiperlan/2, HiperAccess and HiperMan areas. In particular, he contributed to the architecture of HiperAccess systems, including optimization of spectral efficiency, design of the DLC layer and appropriate testing methods (together with ETSI PTCC). Bernd also supported the harmonization between BRAN HiperAccess and IEEE 902.16 Wireless MAN-SC as well as the co-operation between ETSI and WiMax. Since 1980, he has been with Marconi Communications in Backnang, Germany (formerly known as AEG-Telefunken, ANT Telecommunications, Bosch Telecom), now working in the R&D department of wireless access systems, in particular on the system design of broadband wireless cellular systems. He is also a lecturer at the University of Karlsruhe and he has authored a textbook on coding and information theory. He is a member of ITG, IEEE and AMS. Bernd graduated in mathematics and information science from the Technical University of Braunschweig, Germany. He received a PhD in electrical engineering from the University of Erlangen-Nürnberg, Germany. He was appointed Honorary Professor at the University of Karlsruhe, Germany.

Title: IEEE Standard 802.16 for Broadband Wireless Metropolitan Area Networks

Abstract: While the world's data transmission capacities are growing at an enormous rate, relatively few users have broadband access to them. Wired solutions, including fiber, cable modems, and digital subscriber lines, have limitations that prevent ubiquitous deployment. Broadband wireless access (BWA) is an alternative that offers quick build-out at a low cost. A key issue for the success of these systems is global standardization. Within the IEEE 802 LAN/MAN Standards Committee, the 802.16 Working Group on Broadband Wireless Access, with hundreds of participants worldwide, has recently completed the WirelessMAN air interface standard for fixed wireless metropolitan area networks. Supporting industry groups, such as the WiMAX Forum, have blossomed, and Working Group is nearing completion of the P802.16e project to extend the standard to address mobile terminals as well. This talk provides an overview of the 802.16 technology, which is based on a QoS-oriented point-to-multipoint medium access control layer and both single-carrier and OFDM/OFDMA physical layers.

Speaker: Dr. Roger B. Marks

Bio: Roger B. Marks ( is with the National Institute of Standards and Technology (NIST) in Boulder, Colorado, USA. In 1998, he initiated the effort that led to the IEEE 802.16 Working Group on Broadband Wireless Access, chairing it since inception and serving as Technical Editor of several standards. He also serves actively on the IEEE 802 Executive Committee. Marks received his A.B. in Physics in 1980 from Princeton University and his Ph.D. in Applied Physics in 1988 from Yale University.
