In key fields such as satellite navigation, power dispatch, and ocean transportation, a more powerful "private network" than mobile networks is silently operating - this is wireless private networks. When natural disasters cause ground network paralysis, this system will become the last line of defense to safeguard the communication lifeline.

According to a report by market research firm Dell'Oro Group, the wireless private network market is expected to experience explosive growth in 2024, with revenue increasing by over 40% year-on-year. Even more exciting is that this market is expected to maintain a growth rate of over 20% by 2025, becoming the most dynamic segment in the wireless communication field.

With the steady progress of international low orbit satellite constellations such as Starlink, Project Kuiper, and Telesat, as well as domestic plans such as China's Star Network GW constellation and Qianfan constellation, satellite communication and ground cellular networks are moving from competition to deep integration. This integration is unleashing the deep value of satellite communication: breaking through blind spots in ground network coverage, providing seamless connections for remote areas, oceans, and airspace, and promoting the deep embedding of communication capabilities into vertical industries such as transportation, electricity, and emergency response.

The 'last resort to communication' in extreme scenarios

The ultimate test of communication security often occurs in extreme scenarios. When both satellites and ground networks fail, ad hoc networks become the "last resort" for communication - terminal devices can quickly build resilient communication links in extreme scenarios such as ruins, wilderness, and disaster areas through dynamic networking and intelligent routing, without the need for a central node. This' decentralized 'survival capability, in conjunction with the satellite' Skynet ', strengthens the lifeline of' continuous connectivity without network interruption '.

K1000 baseband chip successfully lights up

To integrate the wide area coverage capability of satellite communication with the end-to-end resilience of ad hoc networks, the core lies in the technological breakthrough of communication chips. Recently, Shanghai Qingkun Information Technology Co., Ltd., a local communication chip manufacturer, has made significant progress: in response to the integration needs of "satellite ground collaboration+self-organizing network", the K1000 baseband chip independently developed and using mature domestic technology has been successfully lit up, and the verification process has been successfully completed.

This baseband chip using Software Defined Radio (SDR) architecture has become a communication core hardware that combines public network communication and self-organizing network capabilities, providing a new technological solution for communication needs in multiple fields such as satellite communication and emergency communication.

The K1000 baseband chip has the dual advantages of high openness and strong compatibility. The chip is equipped with multiple types of communication accelerators and high-performance processors, which can flexibly adapt to 4G and 5G public network communication protocols. It also supports customized protocols for ad hoc networks such as point-to-point, star, chain, and Mesh, meeting the communication and networking needs of different scenarios.

At the performance level, the chip is equipped with 4T4R MIMO technology, achieving a system air interface rate of 1Gbps throughput. It also supports concurrent applications with heterogeneous broadband and narrowband combinations, as well as layered and clustered large-scale networking, which can adapt to communication transmission requirements in complex environments. In terms of interfaces, the K1000 baseband chip provides rich peripheral interfaces with strong hardware adaptability and scalability.

Building the ability to continuously connect without network interruption

As an enterprise specializing in communication chip design and overall solutions, Shanghai Qingkun Information Technology is deeply engaged in the research and development of communication core technologies, holding 91 authorized invention patents and continuously consolidating key technologies. The company focuses on three core communication scenarios: satellite communication, public network, and self-organizing network, to create low-cost, ultra flexible, anti-interference, and highly reliable communication chips and modules.

According to the product roadmap, it is expected that Shanghai Qingkun Information Technology will launch the next generation of communication chips by the end of 2026. This chip will provide comprehensive support for the five major protocols of 4G, 5G, ad hoc networks, satellite communication DVB, 5G-NTN, and add AI edge inference function. Its technical capabilities and application scenarios will be further upgraded.

Relying on core chip technology, Shanghai Qingkun Information Technology has created a communication solution for vertical industries such as satellite, emergency, vehicle networking, unmanned aerial vehicles, railways, power, and ocean transportation, with a focus on "continuous network disconnection". This provides hardcore technical support for stable communication in key industries and injects new impetus into the construction of China's integrated communication network for air, space, and earth.

With China's accelerated layout in the construction of low Earth orbit satellite constellations and continuous breakthroughs in local communication chip technology, the integrated communication network of space, sky, and earth is moving from vision to reality, providing a solid technological foundation for the construction of a digital China.Editor/Yang Meiling
