re: Ford tests car2x communications

So these days, aggressive drivers often accelerate when they approach see a light turn yellow as they approach an intersection. This device will give those same drivers warning enough to accelerate even faster, even sooner... Sarcasm aside, as Larry suggests, this is happening and it's going to start moving very fast. My bet is that in ten years, automakers will have safe, reliable, roadable fully autonomous concept cars driving around. By the same time, amateurs will have home-built autonomous vehicles all over the roads. There will probably be open source plans freely available and easily buildable. This car2x is one of many early steps going on these days. Only one of many.

We could really use this in Phoenix, the red-light-running capital of the world. I especially like that the optical & acoustic warnings are not only for the driver that is about to run the red light, but also to the other drivers approaching the intersection. A large number of intersections in this town would be ablaze in lights and warning sounds...but I'm sure there would be a lot fewer accidents.

I look at kids under 5 years old today and wonder if they will ever drive a car or just ride around in cars that drive themselves. It seems like this is starting to actually happen. Larry M.

Considering the Ford Sync system seems designed to lure drivers' eyes off the road and onto the multiple-level menus on a large touch-screen, at least they can now warn those same drivers when they are about fly through a stop sign.

This is one of those "It's about time!". Kudos to Ford for getting involved with this early on. With the number of vehicles that I see violating red lights every day, this has the potential to drastically reduce accidents. Of course, there will be some who will either simply ignore the warnings (whether deliberately or because they are distracted by a cell phone, text or passenger) or who will hit the gas to try to get through anyway.

As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
