CATR and MTNet lab
 China Academy of Telecom Research (CATR) is the largest independent
research organization on telecommunications in China, established in mid1950s. CATR is the best 3rd-party provider of standardization, consultancy andtest services on telecommunications in China.
 MTNet is a 3rd-party test lab of CATR, focusing on terminal tests.
 CATR/MTNet lab can provide “one-stop” test service to 2G/3G/LTE terminals
from regulatory-compulsory, global certification, and operator-authorized tests.

CATR/MTNet lab: Providing one-stop terminal test service
In 2011, we tested 4,700 terminals (3,700 GSM + 1000 3G).

CATR/MTNet: Most important 3rd-party lab
in TD-LTE test and trials in China
 China’s TD-LTE test and trials are mainly carried out in CATR/MTNet lab andCMCC’s test fields.
Lab tests and small-scale field trials: in MTNet lab (Finished tests for 10 TD-LTE network vendors
and 10 LTE terminal/chipsets vendors).



Large-scale field trials: in CMCC networks in 6 Chinese cities.



90 technical and test specifications, 2000 test cases have been jointly drafted by CMCC andCATR/MTNet.

Many operators (Vodafone, ClearWire, DT, DoCoMo, KDDI) ever visited CATR/MTNet.

Summary•

TD-LTE industry is growing fast. However the number and quality of terminals is still
the biggest challenge.

•Testing is an effective way to promote TD-LTE terminal R&D.

•Besides the fundamental conformance tests, the operator-defined IoT tests is anessential part. However it often consumes a huge amount of resource of vendors
and operators.

•Operator-authorized terminal pre-tests in 3rd-party labs is a good approach toaccelerate the R&D and test procedure. This will save time resource and lab
resource of vendors and operators, shorten time-to-market, and also attract moreterminal vendors’ join in.

•CATR/MTNet lab has a world-wide unique test-bed including all TD-LTE network
vendors’ equipments and supporting 2G/3G/LTE multi-RAT.

•CATR/MTNet like to collaborate with all operators to promote their TD-LTE terminal
R&D by pre-test following operators’ requirements.

Welcome to visit our world-wide unique test-bed including allTD-LTE vendors’ equipments.
