Editorial: ultra wideband systems technologies and applications

Abstract

Orthogonal technological competition allows the introduction of constructive new products that will allow a minimum interaction with those already in use. Radio technology has the potential for making use of unlimited untapped frequency resources up to terahertz level. The radio technology behind this Special Issue, so called impulse radio (IR) or ultra-wideband (UWB) is approaching its prime and will compete with narrowband RF technology in wireless communications. This will also enable us to make use of traditional pulse techniques to devise suitable solutions for new civil and commercial applications. It is expected that the UWB market for shortrange applications will grow to a quarter of a billion units in the next 5 years.
