CUHK Received International Accreditation for Mobile Phone Radio Performance Test Services 
"List of activities for which accreditation has been terminated (Notification Letter No. HOKLAS197-7; Effective date of termination: 21 September 2017)"

The fulfillment of the ISO/IEC 17025 requirements means that the laboratory meets both the technical competence requirements and management system requirements that are necessary for it to consistently deliver technically valid test results and calibrations. HOKLAS is operated by Innovation and Technology Commission (ITC) of Hong Kong SAR Government and is a member of International Accreditation Forum (IAF) and International Laboratory Accreditation Cooperation (ILAC).

The R3L Laboratory was established in 2007 with university’s strategic investment fund and significant industry sponsorship. The laboratory is equipped with the world class 128-multiple probe spherical near field scanner that is with diameter of nearly 6 meters in a microwave anechoic chamber of 6 by 6 by 7 meters. The OTA test facility supports all the existing wireless communication protocols and is the only university facility of such high caliber in the world.

Prof. Ke-Li Wu, Director of the R3L Laboratory, said over the past three years the laboratory has played irreplaceable role in supporting local wireless industry in product development and test qualification. “Having received the international competence recognition and the world class research capability, the laboratory will provide to the local wireless industry the most authoritative test results and design solutions related to the OTA performance of a wireless product, as well as the Specific Absorption Rate (SAR) that describes the amount of radio energy absorbed by human head,” Prof. Wu said.

Generally, OTA test consists of two parts: spherical effective isotropic radiated power (termed Total Radiated Power, TRP) and spherical effective radiated receiver sensitivity (termed Total Isotropic Sensitivity, TIS). The former measures the spatial coverage of a mobile phone antenna system and its effective radiated power. The latter describes the antenna quality when the mobile phone is in receiving mode and the signal coming from all the possible directions. The OTA test method stipulated in the R3L laboratory follows CTIA (International Association for the Wireless Telecommunications) standard test plan.

Prof. P.C Ching has been awarded the Bronze Bauhinia Star(BBS) by the HKSAR Government for his contributions and services to the Hong Kong community. He is also elevated to IEEE Fellow effective in 2011 for his active involvements in the IEEE Signal Processing Society. He was being recognized "for leadership in engineering education and accreditation".

Congratulations!!

Prof. Wu Ke Li from Department of Electronic Engineering, the Chinese University of Hong Kong has been named an IEEE Fellow effective 1 January 2011. He is being recognized “For contributions to non-planar microwave filters and embedded radio frequency passive circuits”.

The IEEE Grade of Fellow is conferred by the IEEE Board of Directors upon a person with an outstanding record of accomplishments in any of the IEEE fields of interest. The total number selected in any one year cannot exceed one-tenth of one-percent of the total voting membership. IEEE Fellow is the highest grade of membership and is recognized by the technical community as a prestigious honor and an important career achievement. 321 individuals have been elevated to IEEE Fellow for 2011.

Congratulations!!

Prof. Xu has been awarded a CRF Funding of HK$4,000,000 for his group research project.

Project Title: Interface Engineering for Organic Transistors: Materials, Fabrication, Characterization, and Application

Organic semiconductors are of considerable scientific and technological significance. A fundamental understanding of electrical, mechanical, and optical properties of organic thin films is vital in many applications, including organic light emitting devices (OLEDs), organic field effect transistors (OFETs), RFID transceivers, biosensors and hybrid solar cells. This project is focused on the interface engineering of organic transistors that are the key components of large area, flexible, and low-cost organic electronics. Understanding the interface properties of OFETs is essential to device design and will lead to high performance and efficiency. The project involves the collaboration among experts in synthetic chemistry, materials science, physical characterization and measurements, and device physics and engineering, from four Hong Kong universities. It, if successful, will provide an excellent example of the interdisciplinary research.
