Denso, Japan will begin tests of vehicle-to-vehicle communication systems on public roads in Abashiri, Hokkaido, Japan in April. The tests are scheduled to continue through March 2011. Vehicle-to-vehicle communication allows vehicles to interact with each other via radio waves by sending and receiving information. This technology is expected to improve traffic safety, such as in the prevention of vehicle collisions. In the tests, Denso will conduct vehicle-to-vehicle communication using its in-vehicle communications devices at the Ultra High Frequency band between 669 and 679 MHz, and frequency band between 5811.5 and 5828.5 MHz to measure noise and other conditions while vehicles are traveling.

The Japanese government's Ministry of Internal Affairs and Communications (MIC) approved this project as one of the special deregulation zone projects for ubiquitous Internet networking. Denso headquartered in Kariya, Aichi prefecture, Japan, is a leading global supplier of advanced technology, systems and components.
