Description

technical field [0001] The invention relates to a measurement device for mobile communication, in particular to a terminal measurement device for a CDMA communication network. Background technique [0002] At present, the air interface instrument for testing CDMA wireless network, including the antenna with GPS positioning function, is installed on the top of the test vehicle, connected with the portable computer through the data line, and the test mobile phone is placed in the vehicle and connected with the portable computer. The test control software collects and measures the network data. This kind of test equipment is huge and heavy, needs more material resources, manpower and time, and cannot adapt to the needs of the fast-growing wireless communication CDMA network test. The instruments for testing the air interface of CDMA2000 1X EV / DO network introduced abroad are expensive, ranging from US$30,000 to US$50,000, and cannot be accepted and used by regional stations in...
