FCC seeking comments on opening up 5 GHz band

The Federal Communications Commission (FCC) is seeking comments on a proposed rule that would make the 5.85-5.925 GHz band of spectrum available for expanded wi-fi services. The band is currently dedicated to uses associated with connected vehicle programs. FCC officials announced earlier this year that the commission is seeking to open up the 5 GHz band in order to alleviate wi-fi congestion at major hubs, such as airports and convention centres.

The 2115 Federal Communications Commission (FCC) is seeking comments on a proposed rule that would make the 5.85-5.925 GHz band of spectrum available for expanded wi-fi services. The band is currently dedicated to uses associated with connected vehicle programs.

FCC officials announced earlier this year that the commission is seeking to open up the 5 GHz band in order to alleviate wi-fi congestion at major hubs, such as airports and convention centres.  However, there are concerns that the technology to prevent interference isn't mature yet.

The 4944 American Association of State Highway and Transportation Officials, joined by other transportation, technology, and safety groups, has urged protection of the 5.9 GHz band of spectrum so that it could be used for the connected vehicle technology.

The 324 US Department of Transportation (USDOT) connected vehicle program relies on the 5.9GHz band spectrum to transmit the messages that provide key safety information on vehicle position, speed, weather, road conditions, and traffic signal timing.  USDOT is currently in the process of testing connected vehicle technology, a multimodal initiative that will allow for wireless communications between vehicles, transportation infrastructure, and passenger communication devices. While still in early phases, proponents believe the technology will greatly increase safety, through vehicle crash prevention applications, improve mobility by allowing drivers to make choices that reduce delays, and improve the environment through less wasted fuel.

The public is free to comment on the proposed rule until 28 May.

    AT4 wireless is to provide testing services to assess the fair coexistence of wi-fi and LTE in unlicensed spectrum (LTE-U) devices in accordance with the Wi-Fi Alliance Coexistence Test Plan. The testing assesses whether commercially available LTE-U devices coexist fairly with wi-fi in the same environment. The development and deployment of LTE-U devices, which utilise 4G LTE radio communications technology in the unlicensed spectrum, introduces the possibility of interference with wi-fi equipment operat
