The end of an era! Sichuan China Unicom: Termination of China Unicom service based on independent research and development of TD-SCDMA technology

According to news on July 22, today, the Sichuan Branch of China United Network Communications Co., Ltd. officially issued an announcement announcing that it will officially terminate the Daling Tong business service at 24:00 on August 29, 2024, marking the traditional wireless fixed-line business comprehensive delisting. To put it simply, DHS is the common name of CDMA450. Compared with PHS, PHS, it is named DHS. Later, SCDMA 400 was also called China Telecom. SCDMA China Telecom has built networks in most cities in China, while CDMA 450 China Telecom has only built networks in remote areas of my country. CDMA450 is a technology that works at 450MHz and uses CDMA2000 as its core. SCDMA 400 operates at 400MHz and is the 2G version of my country's 3G standard TD-SCDMA. Dalingtong adopts China's independently developed TD-SCDMA core technology, including smart antennas, time division duplex and software radio, which significantly improves signal strength and call quality. In addition, Dalingtong also performs well in terms of radiation control and confidentiality, with an average transmit power of only 0.05W, ensuring a green and environmentally friendly user experience, and using comprehensive encryption technology to ensure the security of users' calls and personal information. However, with the continuous upgrading of mobile communication technology and intensified market competition, Dalingtong's business is gradually facing challenges. Sichuan Unicom's announcement to terminate Dalingtong's business services is based on the rapid development of telecommunications service technology and changes in market demand. The announcement pointed out that because the network equipment and technical support can no longer provide effective services, China Unicom business has to withdraw from the stage of history (the cash balance of the original China Unicom business account can be refunded, and the gift fee can be transferred to your designated China Unicom business account to continue use.).
