Since The Federal Communications Commission (FCC) of USA approved the unlicensed use of TV White Space (TVWS) in November 2008, lots of TVWS utilization related activities have been conducted by regulators and standardization organizations in the other countries and regions. The Infocomm Development Authority (iDA) of Singapore announced a call for TVWS Technology Trial (Singapore Trial) in April 2010 and organized the Singapore Trial in early 2011. The National Institute of Information and Communications Technology (NICT) of Japan, Huawei, I2R of Singapore, MIT and Energy Market participated in the trial. This presentation briefly introduces the TV Band Device (TVBD) prototype developed by NICT for Signapore Trial and the tests conducted by the iDA. Test results for spectrum sensing, Geo-location database access, cognitive radio functionalities and transmitter’s out of band performance will also be presented.

 

Dr. Chunyi Song received his Ph.D. in electronic and communication engineering from Waseda University, Tokyo, Japan. He was a Research Associate in Waseda University during 2007-2009. Since August 2009 he has been with National Institute of Information and Communications Technology (NICT), Japan, as an expert researcher. He was the project coordinator in developing the TV band device prototype for Singapore TV White Space Technology Trial, and he currently is coordinating several projects of developing sensing systems for different implementations. He is also involved in IEEE standardization activities including P802.19.1 and 802.22. He is a member of IEEE, IEEE Standards Association and IEICE.
