5G时代畅想未来英语作文
In the 5g era, the speed is 100 times that of 4G in a large number of conds.
When talking about 5g, many people will think of "fast". So, how fast is 5g?
There is an analogy in the industry: if 2G is compared to a bicycle, 3G is a motorcycle, 4G is a car, and 5g is a high-speed rail.
2g-4g is still a human contact in esnce. However, 5g should not only connect people with people, but also connect people with things and things with things.
In the future, smart homes, smart cities, smart cars and smart robots in the world will all be built on the 5g information highway.
Xiangligang, a communications industry obrver, said that 5g can keep all kinds of intelligent hardware connected.
This also means that 5g will promote the arrival of the era of "Internet of all things" and prof
oundly change people's social life. In the 5g era, people and people, people and things, and things and things will be connected into one, which will build a new Information infrastructure. In the future, 5g will provide urs with more immersive business experiences such as the next generation of social networks and immersive games; At the same time, it will also support a large number of machine communications, making it possible for innovative applications that are difficult to meet 4G, such as driverless, smart home, smart city, etc.
According to the recognized 5g promotion schedule, the current network test will be completed in 2017, the commercial experiment will be started in 2018, the small-scale commercial application will be issued with 5g licen in 2019, and the formal large-scale commercial application will be made in 2020
It is predicted that in the next decade, the global Internet of things will exceed 100billion; Qualcomm believes that by 2035, the total value of 5g LED products and rvices will reach a record $12trillion (about RMB 80trillion).
Under this circumstance, the communication industry will usher in an unprecedented explosion. The manufacturing industry, the Internet and even the human lifestyle will usher in a major change and create new business opportunities.
Typical application scenarios of 5g rvices can be divided into three categories: first, large-scale mobile broadband rvices such as 3D or ultra-high definition video, cond, large-scale rvices such as intelligent logistics, and third, rvices requiring low delay and high reliable connection such as unmanned driving and industrial automation.
5g network architecture is the first wave of commercialization. With the huge demand for ba station construction, basic materials and products such as optical fiber and optical devices are expected to e explosive growth around 2020.
5G时代，大片秒下，速度是4G的100倍。
提起5G，很多人都会想到“快”。那么，5G到底有多快呢？
在业内有一个比喻：如果把2G比作自行车，3G就是摩托车，4G是汽车，5G则是高铁。
2G—4G，本质上还是人联系人。但5G除了人连人，更要实现人连物、物连物。
未来世界中的智能家居、智慧城市、智能汽车、智能机器人等，将全部建筑在5G这条信息高速公路上。
通信行业观察家项立刚说，5G能让各类智能硬件始终处于联网状态。
这也意味着5G将推动“万物互联”时代的到来，深刻改变人们的社会生活。在5G时代，人和人、人和物、物和物都将连成一体，将构建一个全新的.信息化基础设施。未来，5G将为用户提供下一代社交网络、浸入式游戏等更加身临其境的业务体验；同时，也将支持海量的机器通信，让无人驾驶、智能家居、智慧城市等4G难以满足的创新应用成为可能。
按照公认的5G推进时间表，2017年完成现网测试，2018年开始商用实验，2019年小规模商用、发5G牌照，2020年正式规模化商用……
预测，未来十年，全球物联网连接量将突破1000亿；高通认定，到2035年，5G引领的产品和服务总价值，将达到创纪录的12万亿美元（约为80万亿人民币）。
在此之下，通信行业将迎来史无前例的大爆发，制造业、互联网乃至人类生活方式，都将迎来一场大变革，也将创造出崭新的商机。
5G业务的典型应用场景可分为三类，一是3D或超高清视频等大流量移动宽带业务，二是智能物流等大规模业务，三是无人驾驶、工业自动化等需要低时延、高可靠连接的业务。
5G网络的架构，则是第一波商业化浪潮。伴随基站建设的庞大需求，光纤、光器件等基础材料和产品，预计将在2020年左右迎来爆发性增长。
