Caltta Ensures Emergency Communications for Earthquake Rescue in Qinghai
×
On May 14, 2025, the 12th China International Police Equipment Expo, hosted by the Ministry of Public Security, grandly opened at the Shougang International Convention and Exhibition Center in Beijing. With the theme of "New Technology, New Equipment, New-Quality Combat Power," the expo focused on independent innovation in next-generation information technologies, industry applications, and cutting-edge developments.
Caltta, together with ZTE Corporation, participated in the exhibition under the theme "Technological Innovation, AI Empowering Public Security," fully showcasing the achievements of its dual-engine strategy of "localization + intelligence," and deeply analyzing the practical value of AI and private wireless networks in police operations.
During the exhibition, leaders from over 20 public security departments across provinces, municipalities, and autonomous regions—including Beijing, Zhejiang, Guangdong, Jiangsu, Liaoning, Hainan, Jiangxi, and Guangxi—visited the Caltta booth to observe AI-driven innovations in police private networks.
Focusing on application scenarios of AI private networks in the new police ecosystem, Caltta prominently displayed key solutions including BeiDou positioning, public-private network integration, broadband-narrowband convergence, integrated communications, command-intelligence-action coordination, and unified sky-ground integration. The company engaged visiting leaders in in-depth exchanges on technical challenges and innovative practices in the digital transformation of the public security sector.
At this expo, Caltta presented a full lineup of BeiDou-enabled dedicated trunking terminals and base stations, including public network trunking radios, public-private dual-mode radios, private PDT trunking/conventional radios, explosion-proof PDT trunking/conventional radios, broadband/narrowband ad hoc networks, and PDT mobile stations. All equipment adopted new BeiDou-specific positioning chips and antennas, achieving high-precision, strong anti-interference independent BeiDou positioning functions. These are widely applicable in high-reliability scenarios such as patrol deployment, personnel search and rescue, and border inspection, providing crucial support for building a secure and controllable police communications system.
Caltta's public-private integrated communications solution, built on standard protocols, enables system-level interconnection and roaming between public and private networks. It retains the high security and stability of private networks while integrating the wide coverage and flexibility of public networks. It supports coordinated communication across voice, video, and data services, providing a unified and efficient communications base for scenarios such as on-site command and joint law enforcement.
Caltta provides the most advanced broadband-narrowband convergence solutions for systems, terminals, and applications in the public security sector. It builds a visualized, flattened, and intelligent real-combat command platform for police operations, enabling collaborative operation between broadband big data and narrowband real-time voice. This constructs a responsive and precisely-executed flat command system, significantly improving emergency response speed and incident handling efficiency.
Based on a telecom-grade integrated communications architecture, Caltta's platform supports seamless interconnection across multiple terminals, systems, and networks. It integrates PDT terminals, PoC terminals, video devices, and conferencing systems, achieving unified dispatching across regions, networks, and institutions. This helps public security departments build a "horizontally integrated and vertically flattened" combat command hub.
Caltta's command-intelligence-action platform, built on the foundation of "fully integrated communications + DeepSeek large model," delves deep into public security intelligence operations. It offers practical capabilities such as incident monitoring, intelligent analysis, deployment warning, synthetic command, and patrol control. Through large model analysis of voice, image, and location data from the scene, it enables intent recognition and rapid response to commands. This promotes a shift in policing from "experience-driven" to "intelligence-driven," significantly enhancing precision prevention and control capabilities.
Emergency communication assurance plays an extremely important role in responding to sudden events and disasters. Caltta's innovative emergency solution for public security combines the advantages of public and private networks to create an "integrated air-ground-space" emergency communication system that serves both peacetime and crisis. This system achieves seamless interconnection between the emergency scene and the command center, improving cross-domain combat efficiency in scenarios such as counter-terrorism, emergency rescue, and crisis response.
As the complexity of public safety operations continues to rise, Caltta has put forward the forward-looking concept of "AI reconstructing communications," leveraging key technologies such as large models, edge intelligence, and multi-modal sensing to drive the evolution of private wireless networks from connectivity tools to intelligent hubs.
In the future, Caltta will continue to focus on building the full-cycle system of "perception–simulation–decision–action," making continual breakthroughs in intelligent networking, predictive maintenance, and smart decision-making. This will accelerate the development of a trustworthy, secure, and autonomous AI private network ecosystem, comprehensively creating AI-driven new-quality combat power for policing.
Through its dual-engine strategy of technological innovation and deep industry cultivation, Caltta will continue to inject new intelligent momentum into the public security and emergency sectors, contributing to the construction of a safer and more secure China.
