How Other Wireless Devices Can Limit the Benefits of Connected Vehicles

Connected vehicles use advanced wireless technology to communicate with other vehicles and roadside infrastructure. The dedicated short-range communications (DSRC) must be fast, reliable, and secure to ensure the transmission of critical safety messages without delay or interference. The Federal Communication Commission set aside a specific communication channel (5.9Ghz) to be used for connected vehicle safety applications. It needs to be available continuously so that critical information can get through in the split-seconds needed to avoid collisions, and so that as many vehicles as possible can participate.

Channels reserved specifically for this wireless communication have been a critical factor in allowing both government and industry to move forward toward making connected vehicle technology available to the American public—because any interference by other wireless devices and services could hinder the reception of safety-critical communications by blocking access to the channel, interrupting the flow of data between the vehicles, or decreasing the range of the connected vehicle devices. As a result, critical safety applications would not execute their intended functions, crippling the technology’s ability to prevent crashes and save lives.

Dedicated channels for connected vehicle communications ensures that when your vehicle needs access to the wireless network, it is available without fear of interference that could result in harmful situations.
