2024届高考英语热点话题5G技术题型专练——阅读理解 A We’re on the edge of a new age of interconnectedness, when the daily lives of people across the planet will be more closely connected than ever. Advances in technology will lead in the age of fifth generation, or 5G, telecommunications. And this technological evolution will lead to dramatic changes. The first generation of mobile communications, with brick-sized phones, brought just a handful of users expensive and often unreliable voice calling. The second generation introduced digital voice service that was less likely to be dropped, available to many more people and finally cheaper to use. 3G led to a revolution in the mobile Internet, mobile computing, and the increase of apps. 4G made it possible that all we have come to expect of mobile broadband. We take all this connectivity for granted, but the engineering inside the device in your bag or pocket today would have seemed impossible less than 20 years ago. So, where will 5G take us? Think about a world in which not just people but all things are connected: cars to the roads they are on; doctors to the personal medical devices of their patients; augmented reality (AR) available to help people shop and learn and explore wherever they are. This requires a massive increase in the level of connectivity. 5G is the technological answer, making possible billions of new connections, and making those connections secure. 5G will impact every industry — autos, healthcare, manufacturing and distribution, emergency services, just to name a few. And 5G is purposely designed so that these industries can take advantage of cellular connectivity in ways that wouldn’t have been possible before, and to scale upwards as use of 5G expands. But generational change in mobile communications doesn’t just appear overnight. It requires significant effort in research and development and the resources necessary to support that effort. Work on 4G took nearly a decade and the challenges were not easy. There is
