Research in cognitive radio technologies and radiation measurement wins awards

A*STAR Research Institutes win Prestigious Awards

How often have you been frustrated with the performance of your wireless internet access when it just isn’t giving you the “blazing” speeds that you had signed up for? Even if you do get your ‘blazing’ speeds, while blissfully surrounded with the latest high-tech gadgets boasting blue-tooth, wi-fi and wireless capabilities, have you ever paused to consider the level of radiation you might be exposed to?

Well, finding the answers to these questions has certainly reaped benefits for two groups of scientists at A*STAR’s Institute for Infocomm Research (I2R) and the Institute of High Performance Computing (IHPC). Scientists from these two research institutes have recently been honoured with the Prestigious Engineering Achievement Award conferred last Friday (3 Aug 07) by the Institution of Engineers Singapore (IES).

Scientists at I2R have developed a set of cognitive radio technologies to exploit the under-utilised television (TV) bands for wireless broadband services. Cognitive Radio is an advanced radio technology that aims to overcome spectrum scarcity, one of the most challenging problems of modern wireless communications. While most of the available radio spectrum has been allocated, many of the TV bands are under-utilised. By intelligently detecting and making use of the allocated under-utilised spectrum, cognitive radio will allow wireless networks to operate without requiring extra dedicated spectrum.

Research on cognitive radio in I2R led by Dr. Liang Ying Chang to reuse TV bands for wireless broadband access may also potentially hold the key to bridge the ‘digital divide’ between populations in urban and rural communities. Reusing TV bands for long-range wireless communications, without interfering with conventional broadcasting signals, forms the key part of a Wireless Regional Area Network (WRAN) system to give broadband access to rural communities, thus truly providing equal opportunities and access for all in the information society.

On the other hand, with the widespread and ever-growing use of faster and higher speed electronic devices in areas such as wireless communication, automotive or even domestic and household appliances, there are now genuine concerns on the perils of electromagnetic radiation on our environment. Researchers are not only concerned about the biological impact of such radiation on human beings, they are also mindful of the impact of harmful electromagnetic effects on electrical and electronic equipments, which might lead to device malfunction. Hence, all modern electronic and electrical equipment/systems have to undergo electromagnetic field strength testing to comply with compatibility and safety regulations prior to production.

However, there are various limitations to current facilities available to test electromagnetic emissions such as the limited size and mobility of test objects within the test chamber. The use of the traditional test chamber system also faces challenges of having to measure a high complexity of electromagnetic radiation, making it hard to carry out field analysis.

At IHPC, the research team led by Dr Li Er Ping has achieved a breakthrough in its invention of an improved, fully integrated electromagnetic environment testing system that not only has a much improved testing capacity, it has also resolved many of the technical challenges through pioneering advanced reverberation testing technology. This system has allowed companies to overcome numerous testing issues that have previously affected testing adoption, and is now able to provide accurate and efficient test solutions to industries. Underscored by high take-up rates amongst relevant industries, the IES award recognises the impact of this new technique developed by IHPC which has elevated Singapore’s position as a leader in electromagnetic environment simulation systems.

In 2008, I2R and IHPC will be the first A*STAR research institutes to move into Fusionopolis, Singapore’s latest R&D icon for physical sciences and engineering.

Located just a stone’s throw away from Biopolis, the unique co-location of public-private sector R&D capabilities within Fusionopolis promises further research synergy and opportunities to meet the excitement of Singapore’s technology growth.
