The evolution of WCDMA toward high-speed downlink packet access, aiming for peak rates in the order of 8-10 Mb/s, is described as an example of air-interface evolution.
Abstract
Starting with today's 3G standards, future-generation wireless networks are discussed. Two complementing major trends are identified: seamless roaming between different air interfaces, leading to the always best connected concept, and the continuous development of the current third-generation standards. The evolution of WCDMA toward high-speed downlink packet access. aiming for peak rates in the order of 8-10 Mb/s, is described as an example of air-interface evolution. Fourth-generation technologies such as ad hoc networking and multihop networks, still at the research level, are discussed and their impact on wireless communication systems addressed.
