The wide world of wireless heads for generation 3
Article Abstract:
Wireless communication technologies are being propelled into a new generation of equipment, systems and standards, by expanding applications. The promise of such third-generation wireless technologies for providing any kind of information to and from any mobile station. is accommodated by satellite communications very small aperture terminals (VSATs), as well as systems that provide local multipoint distribution services (LMDS). Other technologies, standards and system that may be also used in the newest wave of wireless communications, include code-division multiple access (CDMA) and its various derivatives, Global Positioning System (GPS), several upcoming satellite communications systems such as Globalstar, and other technologies.

Are wild times ahead for wirelesss in 1999?
Article Abstract:
The wireless telephone market is projected to grow by 20% annually in the US and 50% for the rest of the world, with subscribers o6 64 million and a quarter of a billion, respectively. The market will benefit from the influx of third-generation advanced technology that will allow mobile services to offer features such as Internet access, e-mail and multimedia. The introduction of local-multipoint-distribution-service will enable service providers to offer competitive broadband and bundled services to consumers.

Understand the basics of WCDMA signal generation
Article Abstract:
The wide-band-code-division-mutliple-access (WCDMA) technology provides the basis for the development of a Universal Mobile Telephone Service. The technology employs quadrature-phase-shifting-keying modulation. The structure and spreading techniques of the WCDMA technology are reviewed and compared with those of IS-95 CDMA.
