LTE mainly includes TD-LTE and LTE FDD. These two systems are selectively applied according to different 2g and 3G networks. For example, China Mobile adopts TD-LTE, because TE-LTE can be well compatible with the 3G network independently developed by China Mobile. Unicom and Telecom may adopt a combination of two versions, or they may use one of them.
At present, China Mobile is the first to launch 4G, but because it is in its early stage, the coverage is not completely free, and it can only be experienced in some urban areas or counties, and users can use 4G terminals to experience it themselves. The speed is really faster.
Because Qualcomm has occupied the core technology patents in the 3G era, the LTE camp deliberately engages in OFDM to bypass Qualcomm's major technologies, and Qualcomm's position will definitely be weakened compared with the 3G era; What is the meaning of LTE? It's not just technicians who need to know. In the whole communication field, it is believed that understanding what LTE means is very beneficial for people to master the knowledge of communication industry and help people analyze the trend of technology derivation and development.
