ssible to investigate the impact of transmission parameters on performance and the related optimisation. In the context of research in the broader area of broadband wireless networks, the most recent WLAN (dual-band triple mode system) and, via an industrial grant, two UMTS base stations have also been installed. Due to these efforts infrastructure for more advanced research in this area has been created. C.6 DVB-H Introduction Convergence of digital media and communication gives users the chance to consume most digital content in the mobile environment. The emerging DVB-H standard aims to provide digital TV reception in mobile devices. Earlier known as DVB-X, DVB-H is being standardised by an ad hoc group of the DVB organisation standardised at the end of 2004. DVB-H combines traditional television broadcast standards with specific elements to handheld devices, such as mobility, smaller screens and antennas, indoor coverage and reliance on battery power. C.6.1 Motivation for Creating DVB-H The main reasons behind the choice of a new technology to deliver audio/video contents to many mobile users rely on some technical considerations, listed in Table C.1. This new technology is needed in order to face the following issues: power consumption in mobile terminals; performance in the mobile environment, where there is noise, the Doppler effect and impulse interference; network design flexibility, in order to maintain a strong enough signal for single antenna mobile reception in medium to large signle-frequency networks (SFNs).
