There has been a lot of publicity recently surrounding 5G, the next generation of wireless technology for the world. But what is this technology and how might it change our lives?
5G stands for fifth generation, meaning the next step in the progression of technology to replace the current 4G system. 4G was the replacement for 3G, which came after 2G, and so on. Earlier "G" systems were designed to improve mobile communication operations. Each new technology brought major improvements in speed and greatly increased network capacity（容量）. The new 5G system promises more of the same. However, technology experts say there is a major way that 5G is different than the earlier systems. It will move well beyond mobile network technology to affect many more devices and industries than other "G" versions.
Wireless industry groups say 5G will help fuel future "smart cities" by connecting sensor（传感器） networks. 5G is also expected to connect self-driving cars and support new technologies involving virtual reality. Higher 5G speeds could also permit doctors to commonly perform remote medical operations. Factories and businesses could use 5G technology to increase automation and improve the collection of information.
Every coin has two sides. Much of the data could contain private details about individuals, businesses or government organizations. The increased data flow would give internet attackers a lot more possibilities to steal and misuse data. In addition, the wider use of a 5G wireless network means any breakdown of the system would have more widespread and severe results. Such difficulties could affect public safety as well as world economic activity.
