Singapore, Singapore, December 19, 2008 --(PR.com
)-- A team of engineers from A*STAR’s Institute for Infocomm Research (I2R) has developed a white-space sensing device that has received approval for further development by USA’s Federal Communications Commission (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) on 15 Oct 2008. The report consists of test results (both laboratory tests and field tests) from devices submitted by five companies, namely Adaptrum (a small silicon valley startup), I2R, Microsoft, Motorola and Philips. I2R is the only non-USA based company to have the technology tested by FCC. (See Appendix A)
About 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
About the 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.

The rate of correctly detecting occupied and unoccupied channels and the combined cost function are summarized below. If viewed from the point of protecting the incumbent and to maximize the available spectrum, it is desirable to have greater than (>90%) probability of detection for occupied channels (where all devices passed this ‘requirement’) and achieving a high probability of identifying unoccupied channels (I2R’s device also attained 81% that was also the highest ranking).
Note: the last column was added by I2R for ease of interpretation of results
In summary, I2R’s device displayed a consistent ability in sensing
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.
In the report issued by FCC, it was 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.". Satisfied with the results, FCC voted unanimously on 4th November 2008 to approve the use of unlicensed white-spaces device.
Professor Lye Kin Mun, Deputy Executive Director (Research) said, “I would like to congratulate and encourage Ser Wah and the team for this breakthrough. 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.”
The I2R team consists of Dr Oh Ser Wah, Bruce Le Tran Phuoc Cuong, Zhang Weiqiang, Dr Zeng Yonghong, Syed Naveen Altaf Ahmed, Tie Lok Tiing, Lee Chong Yee, V. P. Kumar, Dr Francois Chin, Dr Liang Ying-Chang.
