The technological fantasies of Satellite+ : The root of large-scale application is to reduce costs. When driving in Medog, Tibet, you can save yourself by directly connecting to the satellite through your mobile phone; when you are attacked by Capricorn in Hainan, you can use Tiantong satellite network signals to achieve stable phone calls and short message sending... How to communicate smoothly with the outside world has always been a problem that the communications industry is trying to solve. Operators represented by China Telecom are actively promoting technological innovation and promoting satellite communications from black technology to daily standard equipment , which is opening up a new world. The value of satellite Internet applications has emerged. Currently, the number of global mobile terminal users has exceeded 5.6 billion. The huge stock market provides broad imagination space for the development of satellite communications. According to the predictions of the authoritative organization NSR, in the next ten years, the cumulative scale of the global mobile phone direct connection market will reach 66.8 billion US dollars (converted into hundreds of billions of yuan), surpassing the current low-orbit satellite Internet market, which is mainly based on broadband access. With the advent of the 5G era, Satellite+ is expected to become one of the main business forms of satellite Internet. As the main force in informatization construction, China Telecom continues to accelerate its transformation to an innovation-driven platform-based business model, actively deploys a satellite+ product business system, promotes the integration of satellite communications into land, sea, air and space, and meets the personalized needs of users in different scenarios. The mobile phone direct connection to satellite that has attracted much public attention this year is China Telecom's industry chain partner in cooperating with chips, terminals and other aspects. After less than two years of research and development, every aspect of the end-to-end process of the satellite-ground integrated communication system has been achieved to the best of its ability. Technological innovation makes satellite interconnection within reach. Today, with the rapid development of science and technology, satellite communication mobile phones are undergoing an eye-catching change, gradually moving from high-end and mysterious fields to the masses, becoming more and more people-friendly. In the past, satellite communications seemed to be only an exclusive tool for professionals and special fields. Nowadays, it is quietly entering the lives of ordinary people, bringing us unprecedented convenience and new experiences. China Telecom continues to promote technological innovation and achieves seamless connection between mobile phones and satellites. On the one hand, China Telecom meets the growing diversified communication needs of users by improving the coverage and communication speed of satellite networks; on the other hand, it promotes the popularization of terminal equipment and the diversification of applications by strengthening cooperation with upstream and downstream enterprises in the industry chain. At the same time, China Telecom will work with partners in the satellite industry chain to actively promote the Tiantong Satellite System to go global, serve the economic and social development of the Belt and Road countries and regions, integrate into all walks of life, and enter the homes of ordinary people, allowing users to enjoy convenient satellite communication services. Cost reduction is the key to achieving large-scale applications. For the satellite communications industry, whether it is upstream or terminal technical efforts, the ultimate direction is to reduce costs. Strengthening international cooperation and sharing satellite resources and technological achievements are also effective ways to reduce costs. The relevant person in charge of China Telecom Satellite Corporation said that introducing mobile phone direct-connection satellite communication technology to the international market can promote the development of China's satellite communication industry and promote the upgrading and growth of related industrial chains. In 2024, China Telecom held a launch conference for the mobile phone direct-connect satellite service in Hong Kong, officially announcing the launch of the mobile phone direct-connect satellite service based on the Tiantong Satellite System. It will use this as a new starting point to simultaneously start a new journey of international operation of the Tiantong Satellite Mobile System. Users can enjoy seamless integrated communication services between heaven and earth without changing SIM cards or phone numbers. Satellite communication mobile phones have become more and more accessible to the people from once out of reach. This is an inevitable result of scientific and technological progress and also human beings' continuous pursuit of more convenient and efficient communication needs. China Telecom will continue to be driven by market demand and driven by technological innovation to promote satellite communications to empower land, sea, air and space
