Toyota’s idea for future safety technology is all about allowing vehicles to communicate with each other and the near surroundings, announcing its driver of what’s around the corner, or if there is ice o the road, speed limit, pedestrians and more.
Such technology already exists and Toyota as well as other companies are testing it for future implementation. Using dedicated short-range communication (DSRC) technology, vehicles can communicate with each other and roadside infrastructure. The bad news is that this technology can be affected by interference .
“Toyota recognizes and fully appreciates the need to find new and innovative ways to maximize the effective use of the limited spectrum that is available,” said Toyota InfoTechnology principal researcher John Kenney.
“We have been – and continue to be – generally supportive of efforts to open up more spectrum for unlicensed uses. We are not conceptually opposed to sharing the 5.9 GHz spectrum with unlicensed devices. However, we also believe that the creation of a sharing framework, or the implementation of sharing rules, should not occur unless and until a viable spectrum sharing technology is identified and testing verifies that there is no harmful interference.”
The interference could result in delayed or missed driver warnings, rendering the whole system useless and putting the DSRC technology at risk.
