5 Conclusion As a quasi-4G technology, TD-LTE high-speed large-capacity data transmission for the important purpose of the key technologies and network structure has changed in the case of 2G/3G will coexist for a long time in a certain period of time, hybrid network for different positioning and business needs is a more reasonable strategy conducive to supplement the lack of 2G/3G networks in high-speed data services using LTE with the standard-setting process and the development of industry maturity, and TD-SCDMA network further mature the LTE network actual introduction of the strategy can be further refined.
