Indoor Coverage Problems of DVB 802.21 Broadcast Handovers SG September 2008 doc.: IEEE 802.11-08/1039r0 September 2008 Indoor Coverage Problems of DVB 802.21 Broadcast Handovers SG Date: 2008-09-09 Authors: Burak Simsek, Fraunhofer Inst. et al. Stephen McCann, Roke

Quick Review of Tutorial September 2008 Quick Review of Tutorial Broadcast networks are unidirectional (i.e. 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 Burak Simsek, Fraunhofer Inst. et al.

Indoor Coverage Costs too much September 2008 Indoor Coverage Costs too much * Minimal Cost Planning of DVB-H Networks on Existing Wireless Infrastructure David Gomez-Barquero; et al. Burak Simsek, Fraunhofer Inst. et al.

DVB-T in NRW Germany September 2008 Burak Simsek, Fraunhofer Inst. et al.

September 2008 Solution Target is to use WLAN indoors and enable handovers between 802.11 and DVB IEEE 802.11aa Problem areas Synchronization No IEEE problem, but studies going on... Coexistence ??? Burak Simsek, Fraunhofer Inst. et al.

So What? DVB will start a work item on the subject in November September 2008 So What? DVB will start a work item on the subject in November You will then hear more about this topic Many 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 for TG in 802.21 Burak Simsek, Fraunhofer Inst. et al.
