Band plan for DSRC channel spectrum.
V2V communications transmit and receive messages at the 5.8 to 5.9 GHz frequency. The report, however, notes that the FCC is currently considering whether to allow "Unlicensed National Information Infrastructure" devices (such as WiFi-enabled radio, local area networks, cordless telephones, and fixed outdoor broadband transceivers used by wireless Internet service providers) to operate in the same area of the wireless spectrum as V2V.
This could become a problem.
Given that WiFi use is growing exponentially, opening up the 5.8 to 5.9 GHz part of the spectrum could result in many more devices transmitting and receiving information on the same or similar frequencies. As a result, this could lead to potential interferences with V2V communications in ways detrimental to its safety intent.
The report points out that more research needs to be done on whether these WiFi-enabled devices can share spectrum successfully with V2V, and if so, how.
