Shenzhen, China – The 2026 Seminar on Digital “New Infrastructure” Technology and Management for BRI Partner Countries – Cyber Security, organized by the Academy for International Business Officials (AIBO) under China’s Ministry of Commerce, recently visited Caltta Technologies in Shenzhen. During the visit, Caltta shared its practical expertise and technological advancements in digital infrastructure, emergency communications, and cybersecurity with 36 officials and industry experts from developing countries.

As a leading provider of integrated professional communications solutions, Caltta offers a comprehensive portfolio covering DMR narrowband trunking, Push-to-Talk over Cellular, LTE broadband trunking, emergency communications, unified communications, and 5G technologies. Caltta’s professional digital trunking systems and communications networks have been deployed in more than 60 countries and regions worldwide.

Richard Sun, Senior Vice President of Caltta, welcomed the delegation, AIBO faculty members, and representatives from BRI partner countries. He noted that the seminar’s focus on digital new infrastructure and cybersecurity was both timely and highly relevant.

“Digital infrastructure is becoming a fundamental pillar of economic development, public safety, and social resilience,” said Richard Sun, Senior Vice President at Caltta. “Caltta is honored to share our experience in professional communications, emergency response, and secure network technologies. We look forward to deepening practical cooperation with BRI partner countries in technical standards, security governance, talent development, and industrial collaboration, working together to build a safer, more inclusive, and more accessible digital ecosystem.”

Sun Xiao, Deputy Director of AIBO, emphasized that cybersecurity is a global challenge that no country can address alone. Building strong digital security safeguards and fostering a community with a shared future in cyberspace have become essential to high-quality Belt and Road cooperation and sustainable development. She encouraged participants to use the seminar as an opportunity to exchange best practices, explore cooperation opportunities, and apply the knowledge gained to their own national digital development strategies and security governance needs.

Participants visited Caltta’s showroom for an in-depth briefing on the company’s industry-specific solutions. Caltta demonstrated how its private network communications solutions help safeguard critical infrastructure across sectors such as government, public safety, firefighting, rail transit, utilities, and emergency response. Through physical isolation, link encryption, and trusted terminal access mechanisms, Caltta’s solutions are designed to protect professional communications networks against intrusion, eavesdropping, and signal interference.

Participants were also introduced to Caltta’s broadband-narrowband convergence capabilities. The company’s “2+4” broadband-narrowband convergent solution adopts a unified security framework to reduce security vulnerabilities and interconnection risks caused by multiple standalone networks. In emergency scenarios such as network outages or disaster response, Caltta’s broadband and narrowband ad hoc networks, together with portable base stations, support rapid deployment, encrypted communications, and reliable information transmission in complex environments.

During the visit, the delegation watched live demonstrations simulating frontline rescue operations and command-center dispatch scenarios. They also exchanged views with Caltta’s technical experts through interactive Q&A sessions, gaining a deeper understanding of solution architectures, device applications, and practical deployment models.

As part of the seminar program, Caltta’s industry expert delivered a face-to-face lecture covering digital new infrastructure construction, cybersecurity policies and regulations, data security management, and cybersecurity technology applications. The session helped participants deepen their understanding of secure digital infrastructure and gain practical insights into technology deployment and governance. It also supported broader exchanges among participating countries in policy coordination, technical cooperation, and talent development.

Aligned with the Belt and Road Digital Economy International Cooperation Initiative, Caltta will continue contributing its expertise and solutions to global digital governance. The company remains committed to supporting BRI partner countries by sharing best practices in digital infrastructure, cybersecurity assurance, and data governance, while helping cultivate digital technology talent, strengthen independent digital security capabilities, and bridge the global digital divide.
