Title: Guest Editorial: Special Issue Wireless Personal Multimedia Communications
Abstract: Wireless communications are rapidly evolving and start to face enormous challenges to address all the users and network providers' needs in terms of available bandwidth, overall network capacity or innovative services to improve revenue.These challenges involve the evolution of the radio interface, the introduction in the standards of cognitive radio systems, multi-user MIMO or indeed cooperation involving all of the infra structured networks also exploiting cross-layer approaches and novel developments.The series of international symposia on Wireless Personal Multimedia Communications (WPMC) constitutes a rich technical research and business environment where people from all over the world bring their own achievements and results for fostering the progress in mobile communications, aiming for breakthrough ideas to take us well into the next decade.This special issue was planned to include some of the best papers in a wide range of research areas timely when WPMC 2008 was held in Saariselka, Finland on September 8-11, 2008.
