WCDMA in Malaysia

Wideband Code Division Multiple Access (WCDMA) A 3G highspeed digital data service provided by cellular carriers that use the time division multiplexing (TDMA) or GSM technology worldwide, including AT&T (formerly Cingular) and T-Mobile in the U.S. WCDMA works on WCDMA cell phones as well as laptops and portable devices with WCDMA modems [1]. Users have typically experienced downstream data rates up to 400 Kbps [1]. WCDMA has been used in the Japanese Freedom of Mobile Multimedia Access (FOMA) system and in the Universal Mobile Telecommunications System (UMTS); a third generation follow-on to the 2G GSM networks deployed worldwide [1]. Although TDMA and GSM carriers both use TDMA modulation, WCDMA stems from CDMA. Part of the 3GPP initiative, the International Telecommunication Union (ITU) refers to WCDMA as the Direct Sequence (DS) interface within the IMT-2000 global 3G standards [1]

The interplay between standardization and technological change: A study on wireless technologies, technological trajectories, and essential patent claims

In many technology fields, standardization is the primary method of achieving alignment between actors. Especially if strong network effects and increasing returns are present, the market often ends up with a single standard that dominates the technical direction, activities and search heuristics, for at least one full technology generation. Although literature has addressed such decision processes quite extensively, relatively little attention has been paid to the way in which standards affect - and are affected by - technological change. Building upon the concepts of technological regimes and trajectories (Dosi, 1982), and on the methodology proposed by (Hummon & Doreian, 1989) to empirically investigate such trajectories, this papers aims to study the interplay between standardisation and technological change. We conclude that the empirically derived technological trajectories very well match the standardisation activities and the main technological challenges derived from the engineering literature. Moreover, we also observe that the Hummon & Doreian methodology can indeed reveal technological discontinuities. To the best of our knowledge, this has not been the case in earlier studies using this technology, and refutes concerns that this methodology has a (too) strong bias towards incremental, continuous technological paths. Finally, we compare the set of patents in the most important technological trajectories to the set of so-called essential patent claims at standards bodies, and conclude that there is no significant relationship. This confirms earlier arguments that essential patents are not necessarily ‘important’ patents in a technical sense.technological trajectories, standardization, innovation

Adaptive Wireless Networking

This paper presents the Adaptive Wireless Networking (AWGN) project. The project aims to develop methods and technologies that can be used to design efficient adaptable and reconfigurable mobile terminals for future wireless communication systems. An overview of the activities in the project is given. Furthermore our vision on adaptivity in wireless communications and suggestions for future activities are presented

The MobyDick Project: A Mobile Heterogeneous All-IP Architecture

Proceedings of Advanced Technologies, Applications and Market Strategies for 3G (ATAMS 2001). Cracow, Poland: 17-20 June, 2001.This paper presents the current stage of an IP-based architecture for heterogeneous environments, covering UMTS-like W-CDMA wireless access technology, wireless and wired LANs, that is being developed under the aegis of the IST Moby Dick project. This architecture treats all transmission capabilities as basic physical and data-link layers, and attempts to replace all higher-level tasks by IP-based strategies. The proposed architecture incorporates aspects of mobile-IPv6, fast handover, AAA-control, and Quality of Service. The architecture allows for an optimised control on the radio link layer resources. The Moby dick architecture is currently under refinement for implementation on field trials. The services planned for trials are data transfer and voice-over-IP.Publicad
