White-space sensing device approved by FCC for further development

December 20, 2008

A team of engineers at Singapore's Institute for Infocomm Research (I2R) has created a white-space sensing device that has received approval for further development by the Federal Communications Commission (FCC).

I2R, one of the research institutes sponsored by Singapore's A*STAr (Agency for Science, Technology and Research) was the only non-USA based organization whose technology was tested by FCC.

White space refers to unoccupied frequency spectrum that does not require an FCC license to operate on. It has the potential of opening up a new wave of technology innovations replicating the success of WiFi.

FCC officially released the test report on TV white-space device testing (spectrum sensing for cognitive radio) in Oct. 2008. The report consists of results from laboratory and field tests on devices submitted by Adaptrum, Microsoft, Motorola, Philips and I2R.

I2R's device displayed a consistent ability in sensing digital TV (ATSC format) signals' occupancy and un-occupancy using spectrum sensing technique in actual field tests with an 81% detection rate.

For wireless microphone field tests, I2R's device was able to detect the wireless microphone transmissions during the live performance / game test while correctly identifying some unoccupied channels.

The report issued by FCC mentioned, "At this juncture, we believe that the burden of 'proof of concept' has been met. We are satisfied that spectrum sensing in combination with geo-location and database access techniques can be used to authorize equipment today under appropriate technical standards and that issues regarding future development and approval of any additional devices, including devices relying on sensing alone, can be addressed."

FCC voted unanimously on Nov. 4, 2008 to approve the use of unlicensed white-spaces device.

"This simply proves that our in-house developed technologies are able to compete with the global offerings on a level playing field. I see this area as having immense potential for further research by the team at I2R," said Lye Kin Mun, Deputy Executive Director for research at I2R, one of the research institutes headquartered in the new Fusionopolis centre for physical sciences and engineering R&D.

Institute for Infocomm Research:

The Institute for Infocomm Research (I²R - pronounced as i-squared-r) is a member of the Agency for Science, Technology and Research (A*STAR) family. Established in 2002, our mission is to be the globally preferred source of innovations in `Interactive Secured Information, Content and Services Anytime Anywhere' through research by passionate people dedicated to Singapore's economic success.

I²R performs R&D in information, communications and media (ICM) technologies to develop holistic solutions across the ICM value chain. Our research capabilities are in information technology and science, wireless and optical communications, and interactive digital media.

We seek to be the infocomm and media value creator that keeps Singapore ahead. Website: www.i2r.a-star.edu.sg

Agency for Science, Technology and Research (A*STAR):

A*STAR is Singapore's lead agency for fostering world-class scientific research and talent for a vibrant knowledge-based Singapore. A*STAR actively nurtures public sector research and development in Biomedical Sciences, Physical Sciences and Engineering, with a particular focus on fields essential to Singapore's manufacturing industry and new growth industries. It oversees 19 research institutes and consortia and supports extramural research with the universities, hospital research centres and other local and international partners. At the heart of this knowledge intensive work is human capital. Top local and international scientific talent drive knowledge creation at A*STAR research institutes. The agency also sends scholars for undergraduate, graduate and post-doctoral training in the best universities, a reflection of the high priority A*STAR places on nurturing the next generation of scientific talent.

A*STAR's science and engineering research institutes are headquartered at Fusionopolis.
