Satellite communication solves the problem of terrestrial network coverage
As mobile communications move towards the Internet of Everything, the future 5In the 5G and 6G eras, satellite networks and terrestrial networks will be deeply integrated into one, further accelerating the realization of intelligent full connectivity between people and IoT, wireless and wired, and air, space, and ground. However, the deployment of terrestrial networks still faces many challenges, such as the difficulty of covering vast areas such as oceans, deserts, and mountainous areas, as well as network outages caused by natural disasters and emergencies. These problems not only affect people's daily life and work, but also restrict economic and social development and security.
Satellite communications, as an important complement to terrestrial networks, can effectively solve these problems and provide the possibility of seamless network connectivity on a global scale. Satellite communication has the advantages of wide coverage, flexible deployment, strong anti-interference ability, safety and reliability, and can provide stable communication services at any place, at any time and in any environment to meet the needs of various application scenarios, such as maritime navigation, distance education, emergency communication, environmental monitoring, smart city, etc.
UNISOC V8821 subverts the traditional satellite communication mode
However, there are also many shortcomings in the traditional satellite communication mode, such as high terminal equipment, large size, high power consumption, large signal delay, single service type, etc., which limit the popularization and development of satellite communication. In order to overcome these problems, UNISOC has launched an innovative 5G NTN solution based on the 3GPP standard, which uses 5G technology to realize the communication mode of intelligent terminals directly connected to satellites, breaking the mode and limitations of traditional satellite communication and bringing users a new communication experience.
UNISOC V8821 is the core product of the solution, which is a highly integrated satellite communication chip, which integrates common functions of communication equipment such as baseband, radio frequency, power management, and storage, and is manufactured using advanced 22nm process, supports R17 IoT-NTN standard, and can realize two-way voice call and data transmission functions. The chip supports S, L dual band, through L-band maritime satellite and S-band Tiantong satellite, to provide data transmission, text messaging, call and location sharing and other functions, and can be extended to support access to other high-orbit satellite systems, widely used in the ocean, urban edge, remote mountains and other cellular network difficult to cover the communication needs. The chip also supports the TCP IP protocol, which is suitable for a variety of upper-layer services, inherits commonly used IoT protocols, and can quickly access existing data platforms. In terms of hardware configuration, the chip can flexibly support customers to reuse hardware resources in the original solution, thereby improving deployment efficiency and avoiding problems such as high hardware cost and long time consumption. In addition, the chip has the characteristics of low power consumption, wide voltage, wide temperature, etc., and is suitable for more battery types and more diverse temperature occasions.
UNISOC V8821 leads a new era of satellite communication
The advent of UNISOC V8821 is not only a major breakthrough in domestic satellite communication technology, but also a global leader in 5G NTN technology, opening up new communication methods and application scenarios for the realization of ubiquitous connection of space-ground integration.
Compared with other satellite communication methods, the 5G NTN solution based on the 3GPP standard has advantages in terms of terminal popularity, industry integration, and service richness, which makes it at the forefront of satellite-ground integration technology. At present, 5G NTN is leading with IoT-NTN short messages and IoT services, and the terminal satellite chip is 10 times lower than the traditional satellite architecture**, which greatly expands the popularity of the terminal. In the future, it will support NR-NTN voice and broadband data services for 5G mobile phones. 5G NTN is very suitable for building B2B integrated networks and B2C emergency communication networks, and its business model has obvious competitive advantages.
UNISOC 5G NTN solution takes user experience as one of the cores, and is committed to opening up a new horizon for intelligent communication through advanced 3GPP standard technology. Led by this technology, 5G-compliant smartphones will be able to seamlessly switch from terrestrial to satellite, bringing unprecedented communication experiences to those in the most remote corners of the world. For professional users in a wide range of industries, this solution provides a robust, reliable and cost-effective communication guarantee for efficient operations in key areas such as offshore, logistics and emergency management.
In the field of wireless communication, safety and reliability are important factors that cannot be ignored. In critical moments such as natural disasters, long-range exploration, and maritime emergencies, the security and reliability of satellite communications are important factors that cannot be ignored. In critical moments such as natural disasters, remote exploration, and maritime emergencies, satellite communication can provide a stable communication link to ensure the timely transmission of information and the smooth progress of command and dispatch. UNISOC V8821 chip adopts a variety of security technologies, such as encryption algorithms, digital signatures, identity authentication, etc., to ensure the confidentiality, integrity and credibility of communication, and prevent data leakage, tampering and forgery. At the same time, the chip also supports the access of a variety of satellite systems, realizes the diversification and redundancy of satellite networks, improves the reliability and anti-interference ability of communication, and avoids the communication interruption caused by the failure or attack of a single satellite system.
The R&D and launch of UNISOC V8821 chip benefited from UNISOC and the open cooperation with many parties at home and abroad. As a leading communication chip design company in China, UNISOC has rich experience in chip research and development and technology accumulation, and has established good cooperative relations with many operators, satellite companies, terminal manufacturers, and test instrument manufacturers at home and abroad to jointly promote the standardization, commercialization and popularization of 5G NTN technology.
