Dynamic Spectrum Access With And For Vehicles

Haris Kremo

Researcher

Toyota InfoTechnology Center Co.,Ltd., Tokyo www.jp.toyota-itc.com

About the company

• Research center established in January 2001 in Tokyo as a joint venture of:

– Toyota Motor Corporation, DENSO, KDDI, Toyota Tsusho, Aisin Seiki, Kyocera, Toyoda Gosei, and Toyota Industries

• Presence in the USA through

– Toyota InfoTechnology Center, U.S.A. in Mountain View

– Business Research office in New York City

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
