Construction of China Mobile Internet: special FDD-LTE networks, China Mobile, LTE-IT information

IT information news on May 7, according to the IT information sources, China Mobile has big VoLTE after commercial, the remaining GSM frequencies will be used to build FDD LTE networks, construction FDD LTE Mobile network do you use? Do not have TD-LTE?

It turns out that China Mobile is planning a new Internet business, does not match the existing network and business requirements, we can only build.

World wide 4G developed by the Organisation for 3GPP LTE standard, including FDD and TDD mode, standard LTE FDD and TD only small differences between the two models, similarity of 90%.

FDD (frequency division duplex) is one of the two technical support duplex mode, FDD (frequency division duplex) LTE is FDD-LTE. Due to differences in wireless technology, the use of frequency bands and different factors such as the interests of various manufacturers, standardization and production leads TD-LTE FDD-LTE. FDD-LTE has become the most widely used in countries and regions of the world, the Terminal one of the most species-rich 4G.

中国移动将建设物联网：专用FDD LTE网络 - 中国移动,LTE - IT资讯

IT资讯讯 5月7日消息，据IT资讯消息源透露，中国移动要有大动作，在VoLTE商用之后，剩余的GSM频段将用来建设FDD LTE网络，那么中国移动建设FDD LTE网络干嘛用呢？不是已经有了TD-LTE了吗？

原来，中国移动正在酝酿新的物联网业务，现有网络与业务要求不符，所以只能另建。

LTE是由3GPP组织制定的全球通用4G标准，包括FDD和TDD两种模式，LTE标准中的FDD和TD两个模式间只存在较小的差异，相似度达90%。

FDD（频分双工）是该技术支持的两种双工模式之一，应用FDD（频分双工）式的LTE即为FDD-LTE。由于无线技术的差异、使用频段的不同以及各个厂家的利益等因素，FDD-LTE的标准化与产都领先于TD-LTE。FDD-LTE已成为当前世界上采用的国家及地区最广泛的，终端种类最丰富的一种4G标准。
