Vision of future, motivation for research
• Cars will talk to other cars, people, other machines
• Need for wireless connectivity, therefore spectrum for:
– Traffic safety, traffic optimization, automated driving, enhanced travel experience,…
• Current spectrum allocation for vehicular communications:
– The US: 7 channels, 10 MHz each at 5.9 GHz
– Europe: 5 channels at 5.8 GHz
– Japan: 1 channel at 760 MHz for V2V
