GM: US Needs To Protect 5.9 GHz Band As Automakers Roll Out Connected Cars0
Following General Motors’ announcement that it will bring vehicle-to-everything technology to a high-volume Cadillac crossover, the automaker has now called on the U.S. to protect the nation’s 5.9 GHz band, Fierce Wireless reported Wednesday.
GM will use the dedicated short-range communication (DSRC) platform for its future connected cars, which relies on the 5.9 GHz band to communicate with other cars and infrastructure. The calls from GM underscore a technology battle as some major automakers jump onboard with DSRC, which came to life 20 years ago, and other choose cellular-based V2X systems.
The automaker penned a letter to the FCC last week and underscored the importance of protecting the system. The FCC has examined how unlicensed devices could work on the network and studied how they could interfere with safety. Test results haven’t been made public.
Cadillac first rolled out vehicle-to-vehicle (V2V) technology with the CTS sedan, but V2X will allow the high-volume crossover to “talk” to any other connected pieces of infrastructure such as traffic lights, roadways and more. The luxury brand plans to expand the technology to all of its cars after 2023.
