China Telecommunication Technology Labs (CTTL), founded in 1981, was named under the authorisation of the Ministry of Information Industry (MII) and the State General Administration for Quality Supervision, Inspection and Quarantine (AQSIQ). CTTL experienced sustained development and organisation convergence in its history. Current CTTL is administrated by the China Academy of telecommunication Research (CATR) and was formed through service re-organisation and resource concentration by merging three parts of CATR, i.e. the Research Institute of telecommunication Transmission (RITT), the telecommunication Metrology Center (TMC) and the Research Institute for Industry Standard of Posts and telecommunications (PTISR) into an unique body. It is a leading high-tech laboratory on the combined missions of telecommunication technology development, telecommunication product standard and test methods research, telecommunication metrology standard and methods research, products inspection, verification and technical assessment as well as testing instrument metrology and evaluation of communication software.

The development strategy of CTTL is based on the research of telecommunication engineering technology with also related fundamental theory and guided by the national and international telecommunication markets to provide comprehensive services and support to the governmental departments, network operators and manufacturers. The labs has established its quality system according to the ISO/IEC 17025 and achieved successfully accreditation certificates both from the China national accreditation board for laboratories (CNAL) and foreign accreditation bodies (e.g., Datech, Germany). The Accredited scope of the laboratories covers various telecommunication products including all kinds of telecommunication terminals , accessing equipment, transmission equipment, exchange, IP network equipment, multi-media communication equipment, cable, power supply equipment as well as their reliability , electrical safety and electromagnetic compatibility (EMC). CTTL has become an advanced national base in large scale with integrate function for telecommunication and information equipment testing and inspection as well as metrology and calibration of measuring instrument, providing open services to manufacturers and other clients both nationwide and worldwide. CTTL is a designating test laboratory for implementation of APEC-TEL-MRA and also the location of the Secretariat for APEC TEL MRA Working Group in China.
