4G + is a general term for 4G network upgrade in the international and mobile Internet industry. It is used to describe the 4G network with LTE-A carrier aggregation technology. So when did 4G become popular? How long can 4G mobile phone last? Let's take a look at the details.
When was 4G popular? Since 2014
1. 2014 is a very willful year for China Mobile in terms of network, tariff and terminal. In one year of 4G, China Mobile has achieved the goal of rapidly entering the fast lane of development for both terminal price and category, which takes three years to complete in 3G era.
2. By the end of October 2014, 4G users had already broken the 50 million mark. In 2015, China's 4G market entered an avalanche growth.
3. The fourth generation mobile phone mobile communication standard refers to the fourth generation mobile communication technology, abbreviated as 4G. The technology includes TD-LTE and fdd-lte (strictly speaking, LTE is only 3.9G. Although it is publicized as 4G wireless standard, it is not recognized by 3GPP as IMT advanced, the next generation wireless communication standard described by the International Telecommunication Union, so it has not reached 4G standard in a strict sense.
4. Only the upgraded version of LTE advanced can meet the requirements of ITU for 4G. 4G is a combination of 3G and WLAN, and can quickly transmit data, high quality, audio, video and image. 4G can be downloaded at a speed of more than 100Mbps, 25 times faster than the current home broadband ADSL (4 megabytes), and can meet the requirements of almost all users for wireless services.
5. In addition, 4G can be deployed in places not covered by DSL and cable modem, and then extended to the whole region. Obviously, 4G has incomparable advantages.
