What tests are included in vehicle testing?
1 Answers
Vehicle testing includes CW testing and live network testing. Here are the relevant introductions: 1. CW testing: This involves setting up a transmitting antenna in a typical area to emit a single-carrier signal, then conducting vehicle testing along a pre-set route, using a vehicle-mounted receiver to receive and record the signal field strength at various locations. CW testing offers convenient frequency and environment selection, and as it is an omnidirectional single-carrier test, it is relatively easier to avoid test errors caused by other radio wave interference and differences in antenna gain, ensuring good accuracy of the collected data. 2. Live network testing: This involves collecting and recording pilot signal power data from various base stations in an already operational CDMA network using a vehicle-mounted test phone. Since the path loss data is obtained from an actual network, the test data truly reflects the propagation of broadband signals in the local wireless environment.
