Nowadays, 5G pre-commercial is just around the corner, and how far is the 2G clear frequency retreat. All communication operators are accelerating the 5G deployment plan, and 2G retreat has become the focus of attention. It is only a matter of time before leaving. At the World Internet Conference, Huawei’s rotating CEO Xu Zhijun revealed that Huawei will launch a full-service commercial solution for 5G network equipment next year. In the face of 5G trial commercial and commercial time advancement, 2G clear frequency retreat has become the focus of attention. In July of this year, China Mobile also issued a notice on the announcement of closing 2G networks in some countries and regions. The notice said that with the continuous advancement of mobile communication technology, mobile 3/4G networks have become more mature and widely used, and some countries and regions have officially closed 2G networks. The roaming cooperative operators that have closed or are about to close the 2G network confirmed on July 1, 2017 are as follows: It can be seen that Singapore, Taiwan, Australia, the United States, and Canada have all closed or partially closed 2G networks within the country. It is understood that operators in Japan, South Korea, Finland and other countries have clearly proposed to close the 2G network. At the same time, the three major operators in China have put the 2G spectrum re-cultivation work on the agenda. The Ministry of Industry and Information Technology has issued a document to approve China Unicom and China Telecom to deploy 4G networks on some of the original 2G spectrum. The topic of "2G retreat" in China continues, and it seems that 2G communication has already withdrawn from the Chinese stage. However, 5Giii believes that there is still a long way to go before China's 2G clears its network. First of all, 2G clear frequency retreat, it should be at least "almost" after no users use 2G network. However, after the massive migration to 4G, a large number of people still use 2G networks. According to the data previously disclosed by the Ministry of Industry and Information Technology, by the end of May this year, the total number of domestic mobile users was 1.36 billion, of which the total number of mobile broadband users (that is, 3G and 4G users) was 1.02 billion. In the meantime, we have 340 million 2G mobile phone users at the moment, accounting for 25% of the total number of mobile phone users. It is impossible for operators to shut down 2G networks without considering hundreds of millions of users, resulting in the loss of their own users. Moreover, from a humanistic point of view, a large proportion of current 2G users are remote populations and elderly people who use mobile phones only to make calls. If 2G clears the network now, it is mandatory to ask them to buy a 4G smart phone that is more expensive for them, and use the 4G package service that is not used at all. "Do not buy can not call", it is not arrogant. And there are tens of millions of GPRS Internet of Things users. Common Mobike bicycle locks and mobile POS machines are still using GPRS. Can operators directly clear the frequency of the network with the pressure of users and enterprises, or do they have to change the lock or POS? Finally, 4G coverage is low and the uplink rate is slow. At this year's World Communication Conference, China Mobile Chairman Shang Bing said that the 4G population coverage rate exceeded 99% this year. However, it is already in the last month of 2017. Through the experience of life, we know that nowadays in some smaller cities, there are still many places without 4G signals, not to mention towns and villages. The LTE special subframe ratio is not equal to the uplink and downlink ratios, resulting in an uplink rate lower than the downlink rate. According to the barrel theory, when the number of 4G users reaches a certain level and the number of users reaches a certain level, it will cause an upward blockage and a downside situation. It can be seen that if 2G clears the network now, it will cause great pressure on the 4G network. Therefore, the carrier's ship is already too big, and the time required to turn is definitely not completed in one day or two. If you really want to guess a time, it will take at least 5 years for 2G to clear the network. The biggest possibility in China during this time is that mobile closes 3G, China Unicom and Telecom close 2G, and 5G network opens, thus forming 2G, 3G, 4G, 5G coexistence. After that, the operator increased the construction of the 4G base station and the optimization and improvement of the network to solve the worries and complete the migration of the remaining parts of 2G and 3G to 4G. 2G clearing frequency is to save the spectrum resources and reduce the manpower, material and financial resources maintained by the operators, and use the resources to better use 4G and 5G services. Although the initial heart is good, it is difficult to do it. Science and technology are moving forward to serve people better. If we simply pursue the speed of technological advancement, we will only put the cart before the horse. 5G laying, 2G clear frequency retreat, slow work out, not to be able to do it all at once. Finally, as consumers, we must realize that the departure of 2G networks is only a matter of time. Be prepared, respond positively, and greet with joy, that is the correct solution, not to be crushed in front of the wheel of the times.
