Caltta All-Star Lineup | Digital Repeater PR900, an Exemplary Industrial Design
×
On March 3, the global communications industry "weather vane"—MWC 2025—opened in Barcelona, Spain. The theme of this year's conference is "Converge. Connect. Create." focusing on cutting-edge technologies such as 5G-A, Artificial Intelligence (AI), the Internet of Things (IoT), and Quantum Computing. In the private network communication sector, industry users' demand for efficient, secure, and intelligent private network communication is growing rapidly, driving continuous technological evolution, with convergence, AI, and 5G becoming high-frequency terms.
Private network communication is not only the foundation of industry digital transformation but also carries the high-reliability communication needs of critical task scenarios. In this wave of transformation, breaking down network barriers, enhancing intelligence levels, and expanding industry application boundaries with 5G have become the core directions of the evolution of private network communication technology.
As the global leader in converged private network communication, Caltta is committed to connecting the future of industries with innovative communication technologies, continuously exploring converged communication, AI intelligence, 5G applications, and other aspects to provide reliable and efficient communication support for various industries.
Converged communication, which breaks down the barriers between different network standards to achieve interconnection and unified scheduling of resources, has become an inevitable trend in the development of private network communication.
As one of leading dmr radio manufacturers, Caltta continues to promote the development of private network converged communication. In 2014, it launched the industry's leading "2+4" wide and narrowband integrated solution. In 2017, it proposed the full convergence "private network development strategy" and in 2022, released the first-ever "Full Convergence White Paper" in the private network industry, forming the "3+1+N" full-convergence product strategy:
3: Providing 2G, 4G, and 5G full-standard private network communication capabilities, covering various business needs.
1: Relying on the converged communication platform to provide unified network management and integrated scheduling capabilities.
N: The rich digital and intelligent business applications of the private network industry, providing users with critical communication assurance, auxiliary communication methods, and deep integration of various systems to jointly empower intelligent applications.
As the digital transformation of industries accelerates, a single communication model can no longer meet the complex business needs. Multi-network interconnection and the fusion of intelligence have become essential development directions for private network communication.
Caltta's converged communication system has been successfully applied in multiple industries. For instance, in the Jinan Public Security Bureau, the converged communication system serves as the engine foundation for smart policing, integrating communication resources from police networks, video networks, and other networks, aiding the transformation of police command towards precision, systematization, and intelligence.
In the Xinjiang Emergency Management Department, the converged communication system enables vertical multi-level cascading and horizontal front-and-back communication from the region to cities and counties, significantly improving emergency command efficiency and response capabilities across the entire region.
Artificial Intelligence (AI) is reshaping communication networks and enhancing automation and intelligence levels. In the private network sector, traditional scheduling relies on manual analysis and experience-based decision-making, which cannot meet the high-efficiency demands of emergency command and real-time dispatch. The introduction of AI transforms private network communication from "passive response" to "intelligent prediction," driving industries like law enforcement and emergency management to achieve intelligent upgrades.
Caltta integrates the DeepSeek large model deeply into its core product "Integrated Command and Action Cloud" and, with the "full converged communication + domestic large model" technology matrix, constructs a "perception-judgment-decision-execution" full-link closed loop.
This enables full-domain collaboration of police resources, real-time response to emergency situations, and millisecond-level risk warnings, pushing law enforcement management from "experience-driven" to "intelligent-driven" and empowering new types of combat capabilities with new production capabilities, opening a new chapter in smart policing.
The commercial deployment of 4G/5G technology has brought revolutionary changes to private network communication. 4G private networks provide high-reliability, high-security network services, while 5G, with its large bandwidth, low latency, and wide connectivity features, provides more efficient, flexible, and secure communication services for vertical industries, becoming a new engine driving smart transformation.
Caltta, focusing on industry applications, has developed end-to-end 4G/5G private network solutions that provide secure, flexible, efficient, scalable, and customizable network capabilities:
4G/5G Products Customized as Needed: Offering a series of products based on industry needs, supporting independent deployment or integration with existing networks.
IoT Applications: Combining 4G/5G with industry application characteristics, IoT (Internet of Things) is widely applied in industries like energy, electricity, and transportation.
Caltta can provide end-to-end integrated solutions such as "2+5" and "2+4+5," enabling smooth upgrades to 5G networks, reducing evolution costs, and protecting user investments.
Caltta's broadband private networks have already been widely applied in industries such as rail transit, government, public security, airports, ports, and energy, and have successfully supported major events like the 2022 Beijing Winter Olympics, the 70th Anniversary of the Founding of the People's Republic of China, and the 100th Anniversary of the Communist Party of China. Additionally, large-scale deployments have been made in countries like Zambia, Mauritania, and Mozambique.
MWC 2025 has shown us that converged communication, AI intelligence, and 5G industry applications are accelerating the upgrading of the private network communication sector, pushing the industry toward a smarter, safer, and more efficient future. In the face of these trends, Caltta, with its deep technical accumulation and continuous innovation, is committed to creating future-oriented private network communication solutions, connecting people with information, and empowering the intelligent development of industries.
In this private network communication revolution, Caltta is not only a technological explorer but also a driver of industry transformation. In the future, we will continue to use converged, intelligent, and innovative communication technologies to help global industry users enter a new digital era.
