3 Overview n wireless vehicular cmmunicatins 3 Vehicular Cmmunicatin f Intelligent Transprtatin System (ITS) Safety applicatins Nn-safety and cmfrt riented applicatins Regulatins wrldwide ETSI 5.8GHz fr CEN DSRC, ETSI ERM TG37 5.9GHz fr Eurpean ITS U.S. FCC fr ITS Japan 5.8GHz ITS Standardizatin CEN DSRC, ISO/ETSI CALM IEEE 1609/ p (WAVE) Car2Car Cmmunicatin Cnsrtium Prjects Crash Avidance Metrics Partnership (CAMP) Vehicle Infrastructure Integratin (VII) CarTalk2000, PReVENT, e-safety Fleetnet, Netwrk-n-Wheels (NW)

4 Car-2-Car (C2C) Cmmunicatins 4 C2C is meant t be a cmplement t cellular cmmunicatins by prviding very high data transfer rates in circumstances where minimizing latency in the cmmunicatin link and islating relatively small cmmunicatin znes are imprtant.* Applicatins Safety: public safety, danger warning, cperative driving Nn-safety: telematic, inftainment, n-bard internet Technlgies WAVE (IEEE p/1609) Dedicated channel fr vehicle safety and cmmercial applicatins *IEEE Magazine n Wireless Cmm.

11 Scenari 1 f the integrated slutin 11 Service range extensin f VCG via C2C The brken car lcated ut the range f UMTS/GPRS Help request / emergency message picked by passing by vehicles via C2C link Stre and frward when the VCG is back in the UMTS/GPRS range Message disseminatin / frwarding via multihp C2C r mbility predictin

12 Scenari 2 f the integrated slutin 12 Internet access t C2C user via VCG Cars with VCG act as Internet gateways Thrugh the VCG ther C2C users can Use MYCAREVENT service Access internet Additinal services than danger warning may stimulate the C2C market

13 Cnclusins and utlks 13 C2C cmmunicatin is an prmising technlgy Vehicular Cmmunicatin Gateway is the slutin fr secure, reliable and always best vehicular cnnectin The integrated slutin extends the service range f VCG and prvides the C2C user Internet access and general services Challenges freseen: Self-rganized VANET Service discvery and ruting Resurce management in cellular system Business case and billing issue
