On June 29, during the 2023 Shanghai Mobile World Congress, Quectel, an overall solution provider for the Internet of Things, officially announced the launch of a new 5G satellite communication module — CC950U-LS that complies with the 3GPP NTN R17 standard. This product is aimed at the domestic IoT market, and will provide uninterrupted communication network coverage and seamless connection for remote areas such as forests, oceans, and deserts that cannot be covered by cellular networks, or for special application scenarios such as transportation. Samples of CC950U-LS are currently available for customers to test.
Quectel's CC950U-LS satellite communication module is based on Unisoc's first satellite communication SoC chip V8821, which uses an advanced 22nm process and integrates baseband, transceiver, power management integrated circuit (PMIC), FLASH/SRAM, etc., enabling CC950U-LS has more advantages in terms of power consumption, size, and performance.
CC950U-LS complies with the R17 IoT NTN standard, supports Inmarsat and Tiantong dual-satellite communication, and supports the satellite n255/n256 frequency band defined by 3GPP. At the same time, the module can also provide two-way data transmission for various devices, so it is especially suitable for use scenarios that require two-way communication, such as field adventures, offshore operations, etc. In addition, CC950U-LS also has the advantage of low latency and can provide near real-time data communication. For example, the delay of 100B data transmission is about 3s. solution.
Since the main application range of satellite communication is concentrated in special areas such as forests, oceans, and deserts, the standby capability of terminals has become an important consideration in unattended environments. CC950U-LS supports PSM power saving mode and 2.1 V~4.2 V wide voltage operating range, which effectively prolongs the battery life of the terminal and can operate normally even under low power conditions. In addition, considering the complexity of terminal application scenarios, CC950U-LS adopts an easier-to-solder LCC package with a classic 23.6 mm × 19.9 mm × 2.2 mm design, which greatly reduces the development workload for customers when switching products.
At present, this module has participated in the actual satellite network connection test of Tiantong Satellite. The data of various sensors, emergency messages, and terminal locations monitored on site have been transmitted to the platform in real time through satellites, and the effect is good.
Zhang Dong, COO of Quectel, said: "Quectel has always been committed to accelerating the arrival of the era of the Internet of Everything, but the construction of ground mobile networks is limited by areas, costs and other aspects, and it is impossible to achieve full coverage. Satellite communications Quectel’s satellite communication module CC950U-LS based on Zhanrui’s platform is designed to continuously empower vertical industries such as transportation, oil and gas pipelines, maritime affairs, agriculture and environmental monitoring, and animal husbandry monitoring. , to provide users with wide-area ubiquitous connection services. We believe that this cooperation between Quectel and Zhanrui is of great significance to the further development of 5G NTN."
Xian Miao, General Manager of UNISOC's Wide-area IoT Product Operations Department, said: "UNISOC has been actively investing in the research and application of space-ground integration technology, and has achieved outstanding results in standard formulation, technology research and development, and application verification. Based on the first UNISOC has taken the lead in achieving a series of major experimental breakthroughs in 5G NTN technology in the fields of direct connection of mobile phones to satellites and satellite Internet of Things, and has adopted innovative technologies in reducing transmission delay and improving link throughput. technology, which greatly improves the ability of the terminal to connect to the satellite network. With the launch of the Quectel satellite communication module CC950U-LS equipped with UNISOC V8821, it will further facilitate the accelerated implementation of the Internet of Things based on satellite communication and realize the seamlessness of everything. Connect in real time."
