FCC allocates 5.9 GHZ band to C-V2X

Last week, the FCC ended years of uncertainty in spectrum allocation for cellular vehicle to everything (C-V2X) technologies by officially allocating 30 MHZ of that band to that particular use. This means that new devices can be deployed without having to ask the FCC for a waiver.

C-V2X is incredibly exciting. The first uses we'll likely see for it will be broadcasting alerts of accidents and construction zones to motorists, then we'll get intelligent traffic lights that will offer pre-emption for emergency vehicles and indicate to drivers how long lights will stay green or red. More interesting uses will come when we combine this with autonomous driving technology. AVs would be able to communicate with each other to coordinate traffic movements for greater safety and efficiency. Smartphones could act as beacons showing the presence of pedestrians and cyclists.

There's still much to be done; cars will need to be equipped with 5G antennae and lots of equipment will need to be installed along the roads, but this is still a step forward toward a safer, less congested future.

I worry about the use of radio for applications where physical safety is at stake. Just think of what one terrorist could do with an unobtrusive jammer suddenly filling an area with high power radio noise.

I don't think Kernals cares.

They could supplement it with Li-Fi where cars would flash their lights to transmit information

Does this sound like a really dystopian surveillance state to anyone else?

Sure, because the people who already refer to pedestrian push buttons as "beg buttons" will be more than happy to mandate smartphone use just to cross the street.  Better hope your battery doesn't die...

Smartphones wouldn't be the only way for autonomous cars to identify pedestrians, they'd have cameras and lidar for that too, but it would offer an extra layer of security

Funny how often that's the response when you ask tech companies what problem their tech solves.

They'll create strategic and synergetic partnerships to shake up the industry so that problems are now a holistic part of the solution.

Aren't they occasionally set off by motorcycles with imbalances in their engines (ie, the Harley-Davidson V-Twin)?
