Support 5 g electronics challenge course and prospect of The Times

In recent years, mobile communication has realized the leap development.In 1979, the car phone call;In the mid - 80 - s, the phone.The first half of 90 s, people began to use E-mail and Internet;In 2007, smart phones, and explosive popularity.And lead these is through the wireless connection technology.

So far, the mobile communication technology has been from the first generation (1 g) change to the 4th generation (4 g), greatly promote the mobile performance boost.Today, the fifth Generation, i.e., 5 g (5 th Generation) technology has been available, it is said that it is the implementation of ultra-high speed communication 4 g 100 times.Around 5 g, people have devised a new past mobile framework service platform and support social and widely used method of life.5 g is: the advantages of high speed large capacity, low latency and large-scale equipment connection.Through high speed large capacity, and can realize high definition video broadcast and online home health care.Based on its low latency, can dramatically change, including IoT and cars, all kinds of group communication.For example, in the form of remote control to 60 km/h when the car brakes, 4 g control air brake the walking distance of about 1.7 meters, and 5 g is used, the distance is only a few centimeters.Based on the large-scale equipment can be connected to the characteristics of the number of terminals can be connected at the same time for 4 g of dozens of times.In 2019, the United States, South Korea and the UK was introduced in 19 countries in the world such as 5 g commercial service.5 g in Japan is scheduled to start in the spring of 2020 the commercial service, its literal meaning, the first year of 2020 will be 5 g.Worldwide in 2005, sumitomo electric group takes the lead to market has a very high performance of the transistor - "GaN HEMT transistor (gallium nitride)".With the advent of the era of 5 g, its presence increasingly intense, as the support in the age of 5 g electronics under the earnest attention of the world.This special, we will pursue to contribute to the "GaN HEMT" was born by the challenges of course, give prospect on the future development of 5 g at the same time.
