 China Unicom plans to return the 2G network within two years, focusing on IOT and 4G.


This means that the news that China Unicom 2G began to withdraw from the Internet in recent days has been confirmed. As for the timetable for 2G, a Chinese Unicom medium level insider told the China business newspaper that the company plans to complete the withdrawal of the 2G network for about two years, and most of the sites and frequency resources will be used for the construction of the Internet of things and the 4G network. In this regard, China Unicom has not made a specific response. For its competitors, China Mobile told our correspondent that there was no 2G withdrawal plan. China Telecom said it would depend on the VoLTE (IMS based voice service) network development. The CEO analysis of the flying elephant network believes that the 2G retreat will reduce the daily operation and maintenance costs of China Unicom, while also reducing the investment in increasing the coverage of the 4G network. True and false 4G network 2G network was born in 1991, is the second generation of mobile communication technology specifications, digital voice transmission technology as the core, but can not directly transmit information such as e-mail, software and other information, only calls and some such as time, date and other transmission of mobile phone communication technology specifications. Because of this, the words of 4G and 2G will appear at the top of the current 4G user interface. In fact, the current 4G network is only carrying traffic transmission, the real 4G network, voice, SMS and other basic functions are required by the VoLTE network, in this case, unless the user chooses to disconnect the cellular network (2G/3G/4G network) connection, otherwise with the 4G network will always be in the connection state. A China Mobile person told reporters this way. This reporter noted that the China Unicom chose to gradually withdraw the 2G network, and then instead of 2G network instead of volte network. The company is going to use the 3G to carry the 2G. The above China Unicom people told reporters, 3G is an upgraded version of 2G, in addition to carrying voice and text messages, it can also access the Internet. In fact, 3G instead of 2G is a gradual process, and the only existing 2G users are mainly elderly users, and their demand for mobile Internet access is weak, so even if the 4G network is temporarily disconnected, it does not cause back, so there is no need to worry. Xiang Ligang analysis believes that the direct benefit of operators from the 2G back network is the cost reduction, which will support the operators speed reduction, and the user will be an indirect beneficiary. Reduce operating costs Fu Liang, a telecommunications analyst, told our reporter that the three operators had been put on the agenda at the end of 2016 as far as 2G was concerned. As for the reasons why China Unicom took the lead in announcing the 2G retreat plan, Fu Liang believes that one is more scarce in terms of capital and resources than competitors, and the two is that the VoLTE network of China Mobile and China Telecom has not yet been perfected. In addition, the WCDMA network used by China Unicoms 3G network is the most mature of the three operators and the most widely used 3G network in the world. It can also support the voice and access the Internet. In the short term, it is still valuable as a supplement to the 4G network. Market research firm Intek consulting released 2017-2023 years China Internet plus the market of mobile communication terminal equipment research and development trend of Research Report shows that the three operators for a total investment of 3G network, China Unicom Chinese amounted to 244 billion 300 million yuan, 225 billion yuan China Mobile beat the summit, and far ahead of the China Telecom 992 The amount of investment of a billion yuan. The most investment has also brought the best user experience to China Unicom in the 3G era. In addition, thanks to the network standard, the reporters evaluation results from several websites show that China Unicoms 3G network is ahead of the rest two in terms of network speed evaluation. The most disparate result shows that China Unicoms 3G network is 3 times faster than the other two operators. However, the construction of 3G network only lasted about 5 years. China Unicom, which has not yet entered the harvest period, has ushered in the 4G tide, and is forced to migrate 2G users and 3G users to 4G. Because of the small number of users, China Unicoms 2G users are less, but 5 million households, especially by step out, will not have a big impact on the company as a whole. China Unicom basically chased the pace of the industry in 2017, but the depth coverage of the 4G network needs to be strengthened, and the low frequency resources occupied by the 2G network are very valuable, said China Unicom. On the other hand, China Unicom is currently in the 4G, the Internet of things and other areas of commercial investment, 2G base station has been used for nearly 20 years, aging, and need more manpower, material, financial resources to maintain. In contrast, China Telecom and China Mobile are temporarily not moving, Xiang Ligang believes that the 3G network of two companies is poor quality, if the 2G back network, it is difficult to guarantee the quality of voice calls, SMS receiving and receiving services, so the need to improve the VoLTE network after the plan. This view has been recognised with light, and two of the two people believe that within the next 4 to 5 years, the three major operators will completely withdraw the 2G and 3G networks, and the China Telecom and China Mobile are likely to announce the simultaneous withdrawal and closure of the two networks. It is worth noting that the move of China Unicom to return the 2G network is not the first time in the industry. From the perspective of industry development, the frequency reduction 2G network is also the trend of the times. Many overseas operators have closed the 2G network. In January 2017, AT&T, Canadian Bell, Telus and other operators shut down the 2G network; in April 2017, three Singaporean operators M1, Singtel, StarHub, and Australias second major telecom operators, Optus also closed the 2G network; in September 2017, the Australian operator Vodafone closed the 2G network. For this time difference, China Unicom told reporters that, on the one hand, the number of 2G users in China still exists a certain scale, especially the large number of users of China Mobile, even if the proportion of 2G users is small, but the number is still large; on the other hand, the voice service can not be well connected after the 2G is back to the net. Fu Liang suggested that this time lag is also related to the late start of the domestic mobile communication industry. The domestic 3G licensing time is around 2008, and the European and American countries have been using the 3G network between 1998 and 2000. China Mobile is the first operator to get the 4G license in China, but it is still 5 years late than abroad. Fu Liang said. Generally speaking, a communication network from starting to business, to maturity, and then to the harvest period, for the next generation of communication network research, investment, about ten years of time is more suitable, but Chinas mobile communications started relatively late, has been in a hurry chasing, so 3G is not mature directly into the 4G. Fortunately, after more than 20 years of catching up, China is now in the field of mobile communications no longer at the level of the pursuers, but in the same running line with the advanced countries, even in some areas, as well as leading people, so it is difficult for us to be late and get back late. .
