13 January 2005, 6.15 p.m. - 8.45 p.m. 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 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. Biography: 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 Subject: IEEE Standard 802.16 for Broadband Wireless Metropolitan Area
Networks <not available> 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.

09 February 2005, 6.00 p.m. Abstract: The user expectations of wireless mobile communications are increasing with regard to a large variety of services and applications with different degree of quality of service (QoS), which is related to delay, data rate and bit error requirements. Therefore, seamless services and applications via different access systems and technologies that maximize the use of available spectrum will be the driving forces for future developments. Given the increasing demand for flexibility and individuality in society, the mean for the end-user might be assessed. Potentially, the value would be in the diversity of mobile applications, hidden from the complexity of the underlying communications schemes. This complexity would be absorbed into an intelligent personality management mechan! ism, which would learn and understand the needs of the user, and control the behavior of their reconfigurable and open wireless terminals accordingly in terms of application behavior and access to future support services. In the future wireless service provision will be characterized by global mobile access (terminal and personal mobility), high quality of services (full coverage, intelligible, no drop and no/lower call blocking and latency), and easy and simple access to multimedia services for voice, data, message, video, world-wide web, GPS, etc. via one user single terminal. This vision from the user perspective can be implemented by integration of these different evolving and emerging wireless access technologies in a common flexible and expandable platform to provide a multiplicity of possibilities for current and future services and applications to users in a single terminal. Systems of 4G mobile will mainly be characterized by a horizontal communication model, where different access technologies as cellular, cordless, WLAN type systems, short range wireless connectivity and wired systems will be combined on a common platform to complement each other in an optimum way for different service requirements and radio environments which is technically called “Converged Broadband Wireless Platform, or Open Wireless Architecture (OWA)”.
OWA will eventually become the global industry leading solution to integrate various wireless air-interfaces into one wireless open terminal where the same end equipment can flexibly work in the wireless access domain as well as in the mobile cellular networks. As mobile terminal (rather than wireline phone) will become the most important communicator in future, this single equipment with single number and multiple air-interfaces (powered by OWA) will definitely dominate the wireless communication industries.
Based on the “Mission 2020 Plan in Wireless and Mobile
Communications” in many countries including European Union and Biography: Willie W. Lu, is a special
advisor on emerging technologies and strategies in several e-mail: wwlu@ieee.org or willie.lu@ties.itu.int |
