Indoor Coverage Problems of DVB Broadcast Handovers SG Burak Simsek Fraunhofer Institute FOKUS 21-08-0258-00-bcst
Quick Review to Tutorial Broadcast networks are unidirectional (downlink only) They are efficient for broadcasting but need a bidirectional technology as uplink channel State of the art: 3GPP + DVB/MediaFLO/DMB Covers partially uplink channel problems and the coverage problems There are commercial products capable of quasi „handovers“ between 3GPP--DVB-H Problem: Indoor DigitalTV coverage 21-08-0258-00-bcst
Indoor Coeverage Costs too much 21-08-0258-00-bcst

Solution Target is to use WiFi indoors and enable handovers between 802.11 and DVB IEEE 802.11aa Problem areas Synchronization No IEEE problem, but studies going on... Coexistence ??? 21-08-0258-00-bcst
So What? DVB will start a work item on that by November You will hear more about this topic then Most companies have broadcast units Home entertainment + mobile Services: Especially for operators handover between 802.11 and DVB is important Please talk to your colleagues and share your ideas with us PAR/5C coming soon... 21-08-0258-00-bcst
