11, Vodafone, SKT, and so forth. has begun development of TD-LTE test network.
2010 年 11 months, announced the start for the Polish operator AERO2 business TD-LTE merchandise selection, and will in 2011 and commercial deployment of TD-LTE network, the world's primary commercial deployment of TD-LTE scheme. Moreover, the development with the entire world has fifteen TD-LTE test network,
Office Pro Plus 2010, there'll be nine pilot network in early 2011.
FDD in the system chips, etc. is shared; second, for the reason that in some international locations the scarcity of spectrum resources, pick the TDD operators into a new way; 3rd, comparatively talking, TD-LTE advantage with asymmetric transmission, but additionally to adapt the demand for knowledge services.
Fu Liang believes that shifting the time for you to do earlier LTE,
Office 2010 Pro Plus Key, rather than ahead of time as 3G WCDMA, TD and mature specifications along the lines of the time variation amongst the big.
products companies the two palms prepared to move
In accordance to introduction, including Datang, ZTE,
Windows 7 Ultimate Key, Huawei, Nokia Siemens Networks, Alcatel-Lucent, Ericsson and other enterprises in your house and overseas, which include the mainstream technique producers, and sizeable Tang, LCI, Spreadtrum, STE (t3g), Imaginative Video clip, Huawei Terminal Hisilicon other chip organizations, such as TD-LTE would be involved in pilot.
The supply explained that a second motive is that
current,
Office 2007 Pro Plus, China's three major operators in 3 3G requirements, respectively, corresponding for the evolution from 3G to 4G has 3 routes. Among them, the transfer has clearly adopted into TD-LTE; China Unicom currently operates inside the WCDMA traditional is generally in accordance with global practice into FDD LTE, which has Vodafone, Telefonica, AT & T and many other overseas operators experience; while China Telecom's CDMA2000 is not yet conclusive, but the overseas operators that include Verizon, SK, South Korea is turning FDD LTE.
In fact, during the entire world Expo in Shanghai, furthermore to transferring the initial TD-LTE demonstration advancing slowly, China Telecom has deployed the largest LTE test network, using FDD LTE common.
However, the above operators Research Institute told reporters, may be an extreme, if the scale of TD-LTE check results is good, three operators will adopt this ordinary.
Fu Liang explained that although the mobile network is now a clear experimental TD-LTE uses a customary, but in fact,
Office 2010 Home And Business Key, are considering moving compatible FDD. Within the course of evolution to LTE, TD in addition on the other four networks are difficult to achieve a smooth transition, the 3 operators will face large-scale investment and building, so the final choice of which standard is unclear.
