On April 8th, when attending the 2013 Boao Forum for Asia, Wang Jianzhou, the former chairman of China Mobile, said that from a global perspective, 4G is developing rapidly and has become a reality. The technology of the second phase of 4G has been developed, and international 5G research has begun. Wang Jianzhou said that the development of information technology has never stopped, and China ’s cloud computing and LTE have begun to mature during the financial crisis, becoming a very important means of economic development in the region. Wang Jianzhou, former chairman of China Mobile Regarding the development of LTE, Wang Jianzhou said, "If the rate of 3G is 10MB, then the rate of 4G is 100MB, and the second stage rate of 4G is 1000MB." Wang Jianzhou also said that the concept of 5G has been determined, but he did not disclose how much the 5G network speed can reach. He also believes that the mobile Internet has created many new applications, and these applications are changing human life, mobile Internet has become ubiquitous. According to the GSM Association, by the end of 2012, the total number of mobile phones and various mobile devices in use worldwide had reached 6.8 billion, equivalent to the total population of the world. It is estimated that the total number of mobile devices will reach 9.7 billion in 2017. From the perspective of application downloads, it will be 60 billion in 2012 and 110 billion in 2017. I believe this forecast will be conservative and will be even greater by then. Silicon Transistor are solid-state semiconductor devices with functions such as detection, rectification, amplification, switching, voltage regulation, and signal modulation. The transistor acts as a variable current switch and can control the output current based on the input voltage. Unlike ordinary mechanical switches (such as Relay and switch), transistors use electrical signals to control their opening and closing, and the switching speed can be very fast. The switching speed in the lab can reach more than 100GHz.
