Testing device and method of wireless communication terminal

Abstract

The invention provides a testing device and method of a wireless communication terminal. The testing device comprises: a computer testing model and a universal serial bus (USB) cable, wherein the computer testing model is used for fixing a wireless communication terminal to be tested; one end of the USB cable is connected to the wireless communication terminal to be tested and passes through the computer testing model, and the other end of the USB cable is connected to a working computer. In the invention, the performance indexes of the wireless communication terminal measured by the device and method are not influenced by the working computer; the performance indexes of the same wireless communication terminal are basically unchanged when the working computer is changed, so that the comparability of performances between wireless communication terminal products is realized; the repeatability is relatively good, and the realization is relatively simple.

Description

technical field [0001] The invention relates to a wireless communication product testing technology, in particular to a testing device and method for a wireless communication terminal. Background technique [0002] With the rapid development of radio communication technology, there are more and more types of wireless communication products, including voice and data wireless handheld terminals, various portable computers with built-in or external wireless connection devices, etc. Since good transmission performance is the key to ensuring the communication quality of various wireless communication products, it is necessary to use space radio frequency performance testing and its indicators to measure the pros and cons of wireless communication products. Total Radiated Power (TRP) and Total Radiated Sensitivity (TRS) are indicators that reflect the transmitting and receiving performance of the DUT (Device Under Testing, DUT) in the Over The Air (OTA) test. Important indicators...

Problems solved by technology

[0004] However, at present, the OTA test scheme and standards for Single-Input Single-Output (SISO) single-antenna handheld wireless communication products have been relatively complete; but for single-antenna portable computers, wireless communication terminals such as data cards, etc. OTA test methods and standards for Multiple-Input Multiple-Output (MIMO) multi-antenna wireless communication products are still blank

Although many companies around the world pay attention and invest in research, the specific testing method has not yet been clarified
