The fundamental difference between wireless network and wired network lies in the difference of transmission media. Wireless network abandons the traditional network cable and uses radio technology to transmit data at high speed. China's wireless network technology developed later than foreign countries, but it developed rapidly. At present, the three major operators, businesses and enterprises providing basic network services in China are actively deploying wireless networks. Take WiFi construction as an example. Up to now, China Telecom has 300,000 WiFi hotspots in China. He Zhiqiang, director of China Telecom Marketing Department, revealed that 20 1 1 will continue to vigorously promote the construction of WiFi hotspots. By the end of this year, the number of WiFi hotspots will increase to 700,000, and by 20 12, the number of hotspots will increase to 1 10,000. Wang Jianzhou, chairman of China Mobile, proposed at this year's Mobile World Congress (MWC 20 1 1) that the number of WiFi hotspots in China will increase to 1 10,000 in the next three years. However, in China Unicom, the construction of Wifi started late, but it has been actively increasing the construction of Wifi network. In May this year, China Unicom announced that it would strive to cover 40,000 buildings, namely single buildings, by the end of this year. Zhang Zhongping, deputy general manager of China Unicom's network department, said in an interview with the media that China Unicom does not pay attention to the number of hotspots in the coverage of WiFi networks, but comprehensively covers key areas that need data traffic, such as transportation hubs and universities. This is also the consistent deployment of the three major operators.
The gradual increase of WifI network coverage promotes the development of mobile Internet terminals. In modern society, people's demand for mobility and information has risen sharply. More and more people want to access the Internet at high speed in the process of moving, get much-needed information, and complete what they want to do: SMS, download bell maps, mobile music, mobile games, video applications, mobile payment, location services, etc. The existence of wireless networks can provide services for people on the move. We can use the mobile Internet terminal to access the wireless network, through which we can surf the Internet, make video calls, watch movies, play games, shop, send and receive emails and so on.
The gradual improvement of wireless network and the development of mobile Internet terminals promote each other. Without the support of terminal products, the advantages of this network cannot be highlighted, and terminal products will lose their own advantages without the support of wireless networks. Since last year, terminal products have developed rapidly, and products such as smart phones and tablet computers have experienced explosive growth. This has also stimulated the development of wireless networks. The three major operators launched their own terminal products while fully deploying wireless networks, which is a good example. Generally speaking, the rapid development of wireless networks has promoted the development of mobile Internet terminals and is profoundly changing social life in the information age.
