DVB-T Tx -DVB-H signalling required 8k or 2k in existing nw Figure C.5 DVB-H services in the existing DVB-T network with hierarchy Conclusion The future of handheld TV based on the DVB-H standard cannot be predicted today as ultimately it will be driven by commercial and revenue aspects. An even broader vision of an integrated broadband wireless system also including 3G and WLAN, while technically becoming possible, can only be given support by observing the ever-growing need for greater network bandwidth. Once the level of applications and services are achieved this vision requires further studies. There is no doubt that broadband wireless systems will be tested, validated, deployed and undergo ultimate verification in the market place. In preparation for this on the research side, Tampere University of Technology is assembling a unique test and development infrastructure that includes a DVB-H television transmitter and full play-out system plus 3G base stations and WLAN. Appendix D TETRA Network Planning Massimiliano Mattina D.1 TETRA Standard The terrestrial trunked radio (TETRA) standard is an open digital trunked radio standard defined by the European Telecommunications Standardisation Institute (ETSI) to meet the needs of the most demanding private mobile radio (PMR) and public access mobile radio (PAMR) users. Usually the PMR network is owned and operated by a private company or organisation (police, ambulance and fire services, security services, utilities, military, public access, fleet management, transport services, closed user groups, factory site services, mining, etc.). The PAMR network is usually owned commercially and is technically operated by the operator, which sells the network services to companies and organisations as the TETRA facilities allow the network to be shared between the organisations. The TETRA standardisation work was started by ETSI in 1988. The TETRA release 1 standardisation is almost complete and has reached a 100 % acceptance from all European administrations. Elsewhere in t
