In the United States, car technology gets huge upgrade
FEDERAL regulators in the US have approved a big swath of new airwaves for vehicle radar devices, opening the door to cheaper, more precise sensors that may accelerate the arrival of high-tech, next- generation cars.
Many consumer vehicles already use radar for collision avoidance, automatic lanekeeping and other purposes. But right now, vehicle radar is divided into a couple different chunks of the radio spectrum.
The Federal Communications Commission has voted to consolidate these chunks – and added a little more, essentially giving extra bandwidth to

“While we enthusiastically harness new technology that will ultimately propel us to a driverless future, we must maintain our focus on safety – and radar applications play an important role,” said Mignon Clyburn, a Democratic FCC commissioner.
Radar is a key component not only in today’s computerassisted cars, but also in the fully self- driving cars of the future. There, the technology is even more important because it helps the computer make sound driving decisions.
The decision by the FCC lets vehicle radar take advantage of all airwaves ranging from frequencies of 76 GHz to 81 GHz – reflecting an addition of four extra gigahertz – and ends support for the technology in the 24 GHz range.
Expanding the amount of airwaves devoted to vehicle radar could also make air travel safer by allowing for the installation of radar devices on the wingtips of airplanes, FCC Chairman Ajit Pai said.
“Wingtip collisions account for 25 per cent of all aircraft ground incidents,” Pai said. “Wingtip radars on aircraft may help with collision avoidance on the tarmac, among other areas.”
While many analysts say fully self- driving cars are still years away from going mainstream, steps like these could help bring that future just a bit more within reach. — Washington Post.
