The Association of Global Automakers submitted reply comments to the Federal Communications Commission (FCC) on September 2, 2014, asking that the FCC postpone its new rules that would allow for expanded use of Unlicensed National Information Infrastructure (U-NII) Devices in the 5 GHz Band. The comments are attached below.
The Association is asking that the FCC postpone its proposed rules to allow more unlicensed users in the frequency band next to the spectrum designated for connected cars until thorough testing is conducted. V2V safety systems currently under development will send real-time data to notify drivers of potential collision threats, road hazards and congestion. These systems will rely on clear radio frequency to transmit this critical safety information. The rules FCC plans to implement would expand the use of high-powered unlicensed devices in the frequency band next to the 5.850-5.925 GHz spectrum set aside for vehicle safety. Unlicensed devices, such as Wi-Fi, built to comply with these new rules could cause interference in the V2V radio frequency.
The comments included a study by the AdGen Telecom Group which confirms that further research is required to ensure the planned changes will not interfere with V2V technology.
