The rapid development of communication technology has made the Internet of Everything a reality, and the Internet of Things has profoundly affected our way of life. At present, global IoT connectivity is mainly supported by several technologies such as WiFi, Bluetooth and cellular networks. The data shows that the land coverage of cellular base stations is about 20%, while the ocean coverage is less than 5%.
This means that there are still a large number of communication-uncovered areas in land and sea. Satellite communication technology has outstanding advantages such as wide coverage, broadband, low latency, and low cost. It can break through the limitations of ground networks and become an important supplement to the Internet of Everything.
▌Satellite debut to fill the gap in cellular network coverage
Satellite Internet of Things refers to the use of satellite broadband communications to provide Internet of Things services. 3GPP incorporated NTN into the specification in the R17 version. The full name of NTN is non-terrestrial networks, and non-terrestrial networks refer to the realization of NR communication through satellites or high-altitude platform High Altitude Platform Systems (HAPS).
Utilizing the integration of satellite communication network and ground 5G network, it can provide ubiquitous coverage capability, global tracking and positioning without being restricted by topography, and connect multi-dimensional spaces of air, sky, earth and sea to form an integrated ubiquitous interface. Network access, enabling on-demand access in all scenarios.
In recent years, with the rapid development of satellite communication technology, the number of satellites in Low Earth Orbit (LEO), Geostationary Orbit (GEO) and Medium Earth Orbit (MEO) constellations has increased rapidly, and it is expected to provide Internet of Things services. Mobile operators, on the other hand, have partnered with satellite operators to offer hybrid satellite and cellular services, such as emergency SMS and push-to-talk already available on smartphones. The continuous decline in the cost of satellite connections and the deep integration of the two industrial chains of cellular communication and satellite communication all provide basic support for the application of satellite Internet of Things.
The main value of satellite IoT lies in the tracking, control and management of devices in uncovered areas, and as a redundant system for cellular IoT. It can solve the problem of equipment monitoring and management in areas not covered by the cellular network, and can also ensure the continuous delivery of key data streams when the cellular network is disconnected. Fields such as mining offer new paths to problem solving.
▌Joining hands with Qualcomm Technologies to promote the application of satellite Internet of Things
On June 28th, at the MWCSH 2023 Shanghai World Mobile Communications Conference, MeiG Smart joined hands with Qualcomm Technologies, and adopted the latest Qualcomm 9205S modem released by Qualcomm Technologies to make the product of the smart positioning terminal (Tracker) solution by adding satellite communication functions Ability to evolve again.
The new generation of intelligent positioning terminal (Tracker) solution supports 5G NB IoT, Cat.M and two-way satellite links , provides a more comprehensive and flexible communication solution, and has technical advantages such as full area coverage, all-weather and strong disaster resistance. The new generation of intelligent positioning terminal (Tracker) solutions meet the requirements of low power consumption and high efficiency, and realize remote status monitoring, data transmission and precise positioning in the challenging signal environment around the world.
Vieri Vanghi, vice president of product management, Qualcomm Technologies, said: "Qualcomm Technologies and MeiG Smart's continued collaboration has allowed innovation to continue to evolve. The joint expertise of both parties enables the Qualcomm 9205S modem to provide industry-leading features to promote satellite IoT applications. commercialize."
Du Guobin, CEO of MeiG Smart, said: "As an important part of the Internet of Things, the satellite Internet of Things has great application prospects. MeiG Smart is honored to cooperate with Qualcomm Technologies in this field. We believe that the cooperation between the two parties will give full play to Their respective advantages will promote the satellite Internet of Things to play a more important enabling role in the fields of agriculture, energy, and the environment, and will also inject new vitality and innovation into the development of the global Internet of Things industry."
In the future, MeiG Smart will also launch a series of wireless communication module products and Internet of Things solutions with built-in satellite communication functions based on Qualcomm Technologies' solutions, enabling mining, agricultural management, engineering construction, heavy equipment, maritime transportation, energy IoT scenarios such as industry and geological monitoring.
