近年来,我国三大运营商立足移动通信前沿领域,紧随国际主流运营商发展步伐,纷纷加大LTE网络的建设力度。2013年12月4日工业和信息化部发放4G LTE牌照,更是进一步点燃了产业界的热情。目前中国移动、中国电信、中国联通无不热情饱满地投入到LTE网络的部署和运营,上下游系统、设备、芯片和终端等环节也全力以赴地展开LTE生态系统的建设,一场前所未有的LTE发展热潮正在我国掀起。众所周知,LTE两大技术FDD LTE和TDLTE同根同源,两者在基础技术、网络标准、商用网络部署等方面拥有众多相似之处。在LTE生态体系之下,LTE TDD/FDD的协同发展已经具备坚实的产业基础。在汲取3G时代所累积的经验教训的基础上,为了避免市场碎片化,全球领先的运营商从LTE商用之初就提倡LTE
In recent years, China’s three major operators based on the frontier of mobile communications, followed by the pace of development of international mainstream carriers, have stepped up efforts to build LTE networks. December 4, 2013 Ministry of Industry and Information Technology issued 4G LTE license, but also further ignited the industry’s enthusiasm. At present, China Mobile, China Telecom and China Unicom all enthusiastically devote themselves to the deployment and operation of the LTE network. The upstream and downstream systems, equipment, chips and terminals are also making every effort to build the LTE ecosystem. An unprecedented LTE Development boom is set off in our country. As we all know, LTE two technologies FDD LTE and TDLTE with the same root, both in the basic technology, network standards, commercial network deployment and so has many similarities. Under the LTE ecosystem, the coordinated development of LTE TDD / FDD already has a solid industrial foundation. Drawing on the lessons learned from the era of 3G, Leading operators in the world have promoted LTE from the very beginning of LTE in order to avoid fragmentation of the market
