what kind of equipment, what's this dsrc look like? >> guest: yes. the simplest way to understand it is it's just like wi-fi. as a matter of fact, much of the fundamentals are the same. they follow a very similar standard. it's called ao2 .11p, and that's a little bit different from your home wi-fi, and that's ao2.11a, b, g and c. these are all the variations we have refind over the years following -- refined over the years following this concept. ao2.11p is similar, but it is operating in a different channel. but think of it as a wi-fi. >> host: so if you're a driver in a connected car, other connected cars around you, what kind of signals are you getting? what's the interactivity? >> guest: yeah. so there are actually, like, 15 different message sets defined. people dream up all these possible applications. but the simplest one that we always use and we tested on every car is the so-called basic safety message. literally, this basic safety message only tells everybody else here's my position, velocity, acceleration, heading angle, my vehicle weight
