CUHK Received International Laboratory Accreditation
for Mobile Phone Radiation and Passive Antenna Tests
The Radiofrequency Radiation Research Laboratory (R3L) of The Chinese University of Hong Kong recently received the ISO/IEC17025 Certificate of Accreditation under Hong Kong Laboratory Accreditation Scheme (HOKLAS) and becomes the only one in Hong Kong and one of few in the world ISO/IEC accredited laboratories for mobile station Over The Air (OTA) performance, mobile phone Specific Absorption Rate (SAR) test and passive antenna measurement and calibration. The detail can be found at http://www.itc.gov.hk/en/quality/hkas/doc/hoklas/197.pdf .
The fulfillment of the stringent ISO/IEC 17025 requirements means that the laboratory meets both the technical competence and management requirement that are necessary for consistently delivering technically valid test results. 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 and is equipped with a world class SATIMO 128-multiple probe spherical near field scanner in a microwave anechoic chamber and DASY5 EM scanner for SAR test. The OTA test facility supports all the existing wireless communication protocols and is the only university facility of such high caliber in the world. Over the past years the laboratory has played irreplaceable role in supporting local wireless industry by providing the most authoritative test results related to a mobile phone and related accessories.
OTA test consists of two parts namely Total Radiated Power (TRP) and Total Isotropic Sensitivity (TIS). The former measures the spatial coverage of a mobile phone antenna 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 complies with International Association for the Wireless Telecommunications (CTIA) test plan. The SAR test follows the regulations of EN 50360-2001 (European standard) and ANSI C95.1-1999 (IEEE standard).
