10 Car Communication based on Bluetooth Links ITN, October 2009, Lingotto Fiere, Turin Bluetooth Coding sinus wave (440 Hz) encoded by bluetooth

11 Car Communication based on Bluetooth Links ITN, October 2009, Lingotto Fiere, Turin Bluetooth General Information Wireless Connection (2.4 Ghz) Low Power (1mW for Hands Free) compare to 2W for GSM Idea of universal compatibility Wireless Link Hands-Free systems Interest of using Bluetooth for car communication

12 Car Communication based on Bluetooth Links ITN, October 2009, Lingotto Fiere, Turin Bluetooth Radio

13 Car Communication based on Bluetooth Links ITN, October 2009, Lingotto Fiere, Turin Bluetooth profiles What is a profile ? Interface specification for communication between devices Large range of services for bluetooth devices (Hands- free, A2DP (audio streaming), File Transfert, Printer, IRMC, …) Devices must be able to know which profiles are in commun with devices that want to be connected with. Discovery Protocol

14 Car Communication based on Bluetooth Links ITN, October 2009, Lingotto Fiere, Turin Introduction Bluetooth Link Interest of Bluetooth for car communication Different phases of Bluetooth Hands- Free connection Improvements Conclusion

15 Car Communication based on Bluetooth Links ITN, October 2009, Lingotto Fiere, Turin Interest of Bluetooth for car Enable the connection with different phones (for the different users of the car) No Harware/cable is needed High compatibility between phone and the device Phonebook synchronisation Ringtone Volume Accept/Refuse call Discret Mode DTMF Software can be updated easily

16 Car Communication based on Bluetooth Links ITN, October 2009, Lingotto Fiere, Turin Interest of Bluetooth for car Security Reasons Goal : having all phone functionnalities with an easier HMI (Human to Machine Interface) Hands must be substituted by the voice Bluetooth allows universal links with most of the phones

22 Car Communication based on Bluetooth Links ITN, October 2009, Lingotto Fiere, Turin Different phases of Bluetooth Hands free kit connection Discovery Pairing Detection of Profiles Connection Data Synchronisation To complete my phonebook, I have to synchronise with your contacts Ok, I transfer my 163 contacts.

23 Car Communication based on Bluetooth Links ITN, October 2009, Lingotto Fiere, Turin The Hands Free synchronizes its phonebook with the contacts on the mobile phone. The phonebook is vocally available at any time through Voice Recognition, Text To Speech & Voice Tags. Synchronisation is done only once (at first connection) Phonebook synchronisation Automatic Alessandro Del Piero Gianluigi Buffon Fabio Cannavaro Fabio Grosso Tiago David Trezeguet Alessandro Del Piero Gianluigi Buffon Fabio Cannavaro Fabio Grosso Tiago David Trezeguet
