  3. 3. EuTEC Today‘s multi-standard world • Uncoordinated heterogeneous networks create problems! – Difficult to sell service as user does not DVB-H understand coverage strategy there – Users needs to make decision – RX manufacturers need to make decision – Both sides hate the risk of „wrong“ decision Roll-out slow with high risk of failure DAB here 3 European Technology Center MMC 2006 Berlin
  4. 4. EuTEC Today‘s multi-standard world cont. Together today‘s available networks combine many advantages Wide coverage Large number of RXs High bandwidth BC system + Car + Backchannel BC system reception 4 European Technology Center MMC 2006 Berlin
