The FCC unanimously adopted a public notice soliciting new input to update and refresh the 5 GHz rulemaking record to address 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. U-NII devices use the unlicensed 5 GHz band for such applications as Wi-Fi-enabled radio local networks, cordless telephones, and fixed outdoor broadband transceivers. DSRC is used for vehicle to infrastructure (V2I) and vehicle to vehicle (V2V) applications.  The public notice specifically details a couple of proposed sharing techniques, requests submissions of prototypes, and proposes a collaborative test plan.  Comments on the 5.9 GHz public notice are due 30 days after publication in the Federal Register, which has not yet occurred.
