On April 3, 2018, the ministry of industry and information technology finally issued the FDD 4G license to China mobile, and approved China mobile's LTE/ fourth-generation digital cellular mobile communication business.Since the 3G era, the ministry of industry and information technology has approved China telecom and China unicom to use both FDD LTE and TD LTE networks.Compared with the previous two operators, China mobile has only been approved to use the latter type of network. China mobile gets the FDD 4G licence: will 5G be far behind?
China mobile will use the first time to develop the Internet of things in the first place after obtaining the FDD 4G license.To build the world's largest nb-iot Internet of things, but technically, nb-iot can only support FDD LTE.Therefore, China mobile will be able to use the LTE mode of FDD to build the Internet of things, and this is also the network basis for China mobile to realize the "Internet of all things".
In addition because China is a large country, and to enlarge the coverage of 4 g networks in rural and remote areas, how much does it cost to the less population in rural and remote areas, low return on investment, therefore, how to decrease the cost of network creation is very important.In the past, high frequency TDD-LTE coverage was used, and a single base station covered a quarter of the low frequency LTE FDD base station in the rural plain area.After obtaining the FDD 4G license, China mobile can use LTE FDD 900M low frequency band to cover, and also cover a region, so that many base stations can be built less. China mobile gets the FDD 4G licence: will 5G be far behind?
As early as 2016, when China mobile was reported to be ready to build the Internet of things, it was reported that China mobile was ready to build a dedicated network for FDD LTE by using VoLTE's free GSM band.Moreover, China mobile has always been confident in the development of the Internet of things and has already expressed its intention to build the largest nb-iot network in the world.Today, China mobile can also use the FDD 4G license to build the Internet of things on a large scale.Although China mobile's position in the three major carriers is undeniable, it USES different network formats with China telecom and China unicom.
China mobile is still td-lte, which is significantly different from the FDD LTE network used by the other two carriers.Compared with TD LTE, FDD LTE has stronger radiation penetration capability, especially in rural areas, and the use of FDD LTE network mode can reduce the number of base station construction.The low frequency band of LTE FDD 900M can rapidly cover remote areas with high-speed network, while reducing the construction cost, the network communication quality can be improved. China mobile gets the FDD 4G licence: will 5G be far behind?
So what does it mean for China mobile's distribution in 5G after it gets the FDD 4G licence?With the advent of 5G, the global communication industry will set a unified standard, which requires a unified network system.If China mobile is still the continuation of TD LTE standard, so in the age of 5 g can only separate the other to build a communication network, not only expensive cost, communication quality also can not get effective guarantee, laborious.And after China mobile gets the FDD 4G license, it can prepare the two hands for upgrading 5G in the future.
In short, the official release of FDD 4G license will not only enable more business for China mobile, but also reduce the cost of existing network base station construction.In addition, China mobile has finally been on the same starting line with China telecom and China unicom. With strong technical strength, it is sure to develop rapidly. |
