The Ministry of Industry and Information Technology recently issued a satellite mobile communication business license to China Mobile. This means that all three basic telecommunications companies have obtained the qualification to operate satellite mobile communication services, and can carry out services such as direct connection of mobile phones to satellites, enriching the application of emergency communication, maritime communication, remote area communication and other scenarios. Satellite communication unlocks the ability to communicate in all scenarios of land, sea, and air, opening up a new space for the integration of heaven and earth, and unlocking a trillion dollar market. Satellite communication has broken through the geographical limitations of ground communication networks. Satellite communication service is a communication service that uses artificial Earth satellites as relay stations to transmit voice, data, images, and other information between ground stations and user terminals. It has the advantages of wide coverage, large communication capacity, and good transmission quality. This means that even in traditional signal blind spots such as oceans, deserts, and high altitudes, there will be no disconnection, providing communication support for emergency rescue, ocean shipping, field exploration, and other scenarios. It is not only mobile phones that can directly connect to satellites, but also terminal devices such as computers, cars, ships, drones, etc. This will promote the integration and innovation of industries such as communication, transportation, and aerospace, and give birth to new business forms and models. Satellite communication services are expanding towards the mass market. Early satellite communication terminals were mostly professional equipment, and communication terminals and call costs were expensive, which deterred ordinary consumers. With technological iteration, it has now expanded to the field of mass consumption. In China, since basic telecommunications operators launched direct satellite service for mobile phones, many mobile phone manufacturers have launched multiple phones with direct satellite function. By customizing chips and optimizing antennas, satellite communication can be supported, and the cost has gradually become affordable. At the same time, the coordinated improvement of the upstream and downstream industrial chains promotes the transformation of professional communication capabilities towards consumer level terminal miniaturization and low cost, allowing satellite communication to truly enter mass production and life. Launching satellite communication services will reshape the competitive landscape of the communication industry. Currently, satellite communication is mainly divided into two major services: high orbit and low orbit. Among them, high orbit satellites are like "signal towers fixed in the sky" with a large coverage area, making them more suitable for basic support services, such as supporting functions such as phone calls, text messages, and small data traffic directly connected to satellites; Low Earth orbit satellites are like "small signal stations running rapidly around the Earth" with short transmission delays, making them more suitable for scenarios such as direct connection to IoT terminals, vehicle broadband, and low altitude economy. From this, it can be seen that satellite communication will give rise to new profit points, such as emergency satellite packages for individual users, maritime satellite broadband services for enterprises, and IoT satellite access services for industries. Satellite communication has become a new battlefield in the mobile phone industry. Due to the lowered technological threshold, smartphones can also achieve direct connection to satellites. As the cost of satellite communication modules continues to decrease, mid-range models are expected to soon be widely equipped with satellite communication functions. In the current homogenized competition in the mobile phone market, satellite functionality has become a key lever for mobile phone manufacturers to differentiate and break through. Top brands such as Huawei and Xiaomi have launched multiple mobile phones that support satellite communication functions, and small and medium-sized manufacturers are also quickly following suit to jointly promote product innovation and iteration. The satellite function also drives mobile phone manufacturers to cooperate with navigation, emergency, tourism and other service providers, building a new ecosystem of "hardware+services+content". Satellite communication will inject new momentum into the deepening development of the digital economy. On the one hand, satellite communication can cover remote areas that are difficult to reach by ground networks, supporting scenarios such as distance education and e-commerce services, narrowing the digital divide, stimulating consumer potential, and expanding new growth space for the digital economy; On the other hand, the cross integration of satellite communication and industrial Internet, Internet of Vehicles, airborne communication and other new generation information infrastructure has accelerated the emergence of new business forms such as vehicle satellite services, low altitude intelligent networking, accelerated the digital transformation of traditional industries, and laid a solid foundation for high-quality development of the digital economy. Satellite communication is not a replacement for traditional ground communication, but a new pattern of complementary integration. From technological breakthroughs to ecological improvement, satellite communication will consolidate China's leading position in the information and communication industry, achieve a win-win situation for people's livelihoods and industries, and become a key force in promoting China's digital economy to lead the world and building new technological competitive advantages.
