March 2014 doc. : IEEE 802. 11 -14/0397 r 0 Background • FCC allocated 75 MHz of spectrum in the 5. 9 GHz band (5850 -5925 MHz) for Dedicated Short Range Communications (DSRC) in October 1999 § In FCC NPRM 13 -22 (13 -49), the FCC requested comments on a potential sharing of the DSRC band, to understand if a feasible sharing solution that protects DSRC users could be developed. § DSRC would remain as a primary user of the band § The new band would be designated U-NII-4 • 802. 11 ac could be modified to operate in this new UNII 4 band if approved by the FCC • FCC did not specify the framework or etiquette by which band sharing would occur Submission Slide 3 Jim Lansford, CSR Technology

March 2014 doc. : IEEE 802. 11 -14/0397 r 0 Work to date Objectives of the group Create a document that describes and quantifies possible coexistence mechanisms between DSRC and extensions of the 802. 11 base standard in the proposed UNII-4 band, if the FCC allows such band sharing in a future R&O. Possible work items > Review of ITS/DSRC field trials > Review of work to date on coexistence > Presentations on use cases > Presentation of possible coexistence approaches > Modeling/simulation of possible coexistence approaches > Testing, field trials, and presentation of results from proposed prototype approaches Final report > Includes outputs from all work items > One or more “snapshots” (summary of work to date) will be provided to FCC * First snapshot in mid-January Submission Slide 4 Jim Lansford, CSR Technology
