At present, the attitudes of international operators towards TD-LTE have changed significantly. About 20 mobile operators have made it clear that they will adopt or test TD-LTE networks, which is a sharp contrast to the lack of interest in TD-SCDMA. . From the existing public data, China Mobile has signed TD-LTE cooperation agreements with 9 operators to promote the global construction or the upcoming construction of 26 TD-LTE trial networks. According to market forecasts, there will be more than 10 countries in 2011 And regions began commercial deployment of TD-LTE. Japan ’s Softbank is similar to China Mobile and cannot obtain FDD spectrum, so it chose TD-LTE as its 4G evolution technology; although operators such as AERO2, Hi3G, and Telefonica have FDD spectrum, they also need to use TD-LTE as a network load for LTE FDD Supplement; some operators in emerging markets are eager to enter the local 4G market, but suffer from limited funds, and TDD spectrum is cheaper than FDD spectrum, so it is more attractive to them. For example, India ’s Reli-ance Telecom purchases The TDD spectrum is ready for TD-LTE network; some operators lack sufficient confidence in WiMAX and are preparing to upgrade their own WiMAX to TD-LTE network. The representative operators are Clearwire and Yota. The pace of TD-LTE industry maturity is gradually accelerating. At present, an end-to-end industrial chain has been initially established. There are already first-generation systems and terminal products in the fourth quarter of 2010. The industry ’s mainstream operators, system manufacturers, and chips Manufacturers are actively participating in TD-LTE product development and network deployment. The maturity of the terminal is a sign of the maturity of the industry value chain, and the key factors restricting the maturity of the TD-LTE industry are the terminal and the chip. However, with the active intervention of some powerful manufacturers, the maturity of TD-LTE and LTE FDD in the chip and terminal The gap gradually narrowed.
