Evolution of Testing Technology

Testing and evaluation are indispensable links of technology and product inspection. The final birth of every new technology or product must go through strict testing and evaluating process. In the 5G era, the testing tools and evaluation methods are faced with new challenges along with the continuous development of the new 5G technologies. In the section of testing technology evolution of this chapter, we will give a brief review of the history of testing technologies, and make analysis on the development trend of the testing technology ecosystem according to the existing technologies. In the section of testing technology challenges, based on the characteristics of wireless communications technology and 5G technology, we will sort out and analyze the challenges of wireless communications testing technologies in terms of overall performance, the number of RF channels, and high throughput, etc.
