Spectrum sharing plan triggers concerns in US

A group of leading industry professionals has written to the US National Telecom­munications & Information Administration (NTIA) to ask for a rethink, following the announcement by the Federal Communications Commission (FCC) that the 5.9GHz band is to be opened up for spectrum sharing. The group, led by ITS America president and CEO Scott Belcher, includes senior academics, automotive manu­facturers, ITS system suppliers and a number of US state departments of transportation such as those of Michigan, Texas

A group of leading industry professionals has written to the US National Telecom­munications & Information Administration (NTIA) to ask for a rethink, following the announcement by the 2115 Federal Communications Commission (FCC) that the 5.9GHz band is to be opened up for spectrum sharing.

The group, led by 560 ITS America president and CEO Scott Belcher, includes senior academics, automotive manu­facturers, ITS system suppliers and a number of US state departments of transportation such as those of Michigan, Texas and California.

The letter warns that al­though spectrum sharing with­in the 5.9GHz band – which has long been the backbone for ITS services relying upon Dedicated Short Range Com­munications (DSRC) – must be explored, the full implications of doing so have not yet been properly analysed.

“We believe that a com­plete understanding of the feasibility of sharing within the 5.9GHz band based upon a complete record and fair op­portunity for all affected par­ties to participate is essential to this process,” it adds.

Pointing out that the emerging connected vehicle industry has already invested hundreds of millions of dollars and thousands of man-hours to advance projects under the auspices of the US De­partment of Transportation’s Connected Vehicle Research Program, the letter concludes by asking the NTIA to “involve the intelligent transportation industry in the development of NTIA’s position on these issues of critical interest to our industry and the broader trans­portation community”.

The letter follows an an­nouncement on 9 January by FCC chairman Julius Gena­chowski that a government-wide effort to increase speed and reduce congestion in Wi-Fi networks would kick off during February with the unleashing of up to 195MHz of spectrum in the 5GHz band – the largest block of unlicensed spectrum to be made available for ex­pansion of Wi-Fi since 2003.

In the US, the right of cooperative infrastructure to use frequency at 5.9GHz is under threat as a result of the proposal of two bills in Congress.

    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. However, there are concerns that the technology to prevent

    ITS America concerned over use of 5GHz spectrum band
    ITS America has raised con­cerns with the US Federal Communications Commission (FCC) over the potential use of the 5GHz band spec­trum by unlicensed national information infrastructure devices. It wants to protect the 5.9GHz band for dedicated short-range communications (DSRC)-based systems. These crucially underpin the development of connected vehicle (CV) technologies which could help slash the US’ annual tally of six million road traffic accidents and over 30,000 deaths.
