In the past 70 years, China ’s mobile communications have also started from a poor and a poor one. After experiencing 1G blanks, 2G following, 3G breakthroughs, and 4G running, the 5G era has ushered in. Today, China has become a global information and communications power. At the same time, the mobile communications industry has also made a huge contribution to economic and social development, and promoted the transformation of the traditional economy into a digital upgrade.
Since the reform and opening up, China's telecommunications industry has undergone several restructurings and reorganizations, and government functions have been reorganized into central telecommunications enterprises that are adapted to market competition. Changes in identity and system have spurred the upgrade of service content. As the three major operators in China, China Mobile, China Unicom and China Telecom, while fully conducting market competition, continue to make great efforts to meet the specific needs of consumers, so that the people You can afford mobile phones, mobile phones and mobile communication networks.
Half of the radio, red communication started
China's wireless communications industry started not too late. As early as 1876, China's first telegraph line, the Fuzhou City to Mawei Port opened. In 1912, a single telegraph line was laid between Tianjin and Beijing. In 1916, through the ancient magnet telephone, the Chinese made the first call on this telegraph line for the first time.
However, the communications industry at that time was more used for military purposes. For ordinary people, telegraphs and telephones were far from their lives. At that time, the Red Army base was located in a remote mountain, and its communication needs were very urgent. During the first anti-encirclement and suppression, the Red Army seized a radio station with a damaged transmitter and battery, which became the cornerstone of the development of the Red Army's strategic communications command.
Although there are only "half" radio stations left, they can only receive reports but cannot send reports, but they have played a significant role in reconnaissance of the enemy after repair and use. In this battle, more than a dozen radio communication technicians, including Wang Yan and Liu Yin, who belonged to the 5th unit of the 1st Brigade of the Kuomintang Transportation Corps following the 18th Division, were also captured. On January 4, 1931, Mao Zedong and Zhu De met in a ancestral hall in Xiaobu Town, Jiangxi, where the Red Army headquarters was located, and met Wang Xi, Liu Yin, and others to mobilize and welcome them to join the Red Army. They also became the founders of the Red Army's radio communications.
