Eight functions of 3G

Yang peifang, Secretary-General of the Ministry of Industry's telecommunications economic expert committee, said that we used the "Big Brother", called the first generation of mobile communication, and later became a digital mobile communication, which is now called the third generation. The first generation is more powerful than the first generation. The first generation can only call, the second generation can also send text messages, and GPRS can access the Internet.

The third-generation features emphasize more network bandwidth, faster Internet access, and can be delivered by phone. In general, it is the process of upgrading network technology, and there may be new LTE platforms in the future.

Many experts have suggested that 3G is not applicable when 2G is replaced by 1g. However, 3G can see images. Compared with 2g, 3G is a "killer" application, but 3G is a comprehensive platform with eight features.

First, higher quality calls; second, faster Internet access; third, videophone calls; fourth, monitoring and control functions, for example, you can press a number to see whether the door is locked or whether the TV is closed. After a business trip, you can also perform long-distance monitoring and so on. Now there is another technology called "Global eye", which can be controlled through mobile phones. Similar to the portable secretary, you can easily handle monitoring and control functions; fifth, mobile phone positioning. Wherever you are walking, you can combine mobile phones and electronic maps to find hospitals and restaurants nearby, which is more convenient and clearer than 2 GB. 6. Mobile Wallet function; 7, video games that interest young people. Everyone can play games visually, and the market is large. Eighth, video community. Old Students and colleagues can form a community. Both in the south and north of the sky, both in the southern hemisphere and in the Northern Hemisphere, they can regularly meet and hold meetings, join parties, and communicate with each other through community activities. There may be many subdivisions, and with the development of technology, only what we don't think of can't do, it can easily form some new content.
