What Tests Are Included in Vehicle Testing?
1 Answers
Vehicle testing refers to selecting a test route for evaluation. There are two types of vehicle testing: 1. CW Testing: A transmitting antenna is set up in a typical area to emit a single carrier signal, followed by vehicle testing along a pre-determined route. A vehicle-mounted receiver is used to collect and record signal field strength at various locations. 2. Live Network Testing: This involves collecting and recording pilot signal power data from various base stations in an operational CDMA network using a vehicle-mounted test phone. Additional Information: 1. CW Testing: Offers convenience in frequency and environment selection and is an omnidirectional single-carrier test, making it easier to avoid interference from other radio waves and testing errors caused by varying antenna gains. The accuracy of collected data is well guaranteed, making it particularly suitable for localized propagation environment predictions during the early stages of network deployment. The propagation model calibration results based on CW testing can provide accurate propagation predictions for network planning. 2. Live Network Testing: Since path loss data is obtained from an actual network, the test data accurately reflects the propagation of broadband signals in the local wireless environment. The propagation model calibration results based on live network testing are especially suitable for providing field strength predictions for network optimization.
