The FCC is inviting interested parties to update and refresh the record on the status of potential sharing solutions between proposed Unlicensed National Information Infrastructure (U-NII) devices and Dedicated Short Range Communications (DSRC) operations in the 5.850-5.925 GHz (U-NII-4) band.
Those devices provide short-range, high-speed unlicensed wireless connections in the 5 GHz band for, among other applications, WiFi-enabled radio local networks, cordless telephones and fixed outdoor broadband transceivers used by wireless internet providers. DSRC uses short-range wireless communication links to facilitate information transfer between appropriately-equipped vehicles and appropriately-equipped roadside systems (“vehicle to infrastructure” or “V2I”) and between appropriately-equipped vehicles (“vehicle to vehicle” or “V2V”).
The Commission is looking into potential sharing techniques. “In August 2015, the DoT released a DSRC-Unlicensed Device Test Plan that described tests to characterize the existing radio frequency signal environment and identify the impacts to DSRC operations if unlicensed devices operate in the 5.850-5.925 GHz band,” the FCC reports in a statement. “As suggested by two Congressional letters received in September 2015, the Commission is now seeking to refresh the record.”
The National Cable and Telecommunications Association released the following statement on the topic: “The FCC took a significant step forward toward making sharing on the 5.9 GHz band a reality. Not only does the FCC ask the right questions about how to test both the Qualcomm and Cisco sharing proposals, but it also asks how to distinguish crash-avoidance from non-safety DSRC applications.”
The NCTA reports it is committed to finding a sharing solution that works and says the FCC action “points the country in the right direction.”
