Application Cases

Yunnan, located in the southwestern border, has mountainous areas in Qujing, Yuxi, and Xishuangbanna, which make up more than 80% of its land area. The PDT network coverage is extremely limited, with many signal blind spots. By using Caltta's Public-Private Integration System, which connects to the PDT network based on the pSIP protocol, the coverage of the trunking network is maximized, overcoming the limitations of PDT signal range while also providing broadband video services.

Anhui's southern mountainous areas have limited PDT signal coverage in cities such as Wuhu, Anqing, Huangshan, and Chizhou. The province is known for its natural beauty, with many scenic spots. During holidays, the police workload increases significantly. By deploying Caltta's Public-Private Integration System, public network terminals are provided to community prevention personnel, helping establish communication links between public and private networks while supporting community-based prevention and governance, thus reducing the workload of frontline officers.

Located on the East China Plain, Jiangsu hosts many national-level conferences and major events each year, creating significant security challenges. By deploying Caltta's Public-Private Integration System in Suzhou, Jiangsu, and integrating it with PDT systems from different vendors based on the pSIP protocol, the GH960S dual-mode terminals are used. These compact and portable devices lighten the burden on frontline officers while also enabling better communication within the community prevention and governance forces, supporting major public security events.

Caltta's Public-Private Integration System, leveraging the company's more than 20 years of technical expertise in dedicated network communications, has successfully integrated with PDT systems from multiple manufacturers through standardized protocols. It has been widely deployed in over 50 provinces and cities across China in public security departments. The system offers comprehensive functionality, stable operation, and strong compatibility, fully complying with the Ministry of Public Security's PoC standards and specifications. Looking ahead, Caltta will continue to focus on the needs of the public security sector, deeply integrating product features with real-world law enforcement operations. The goal is to provide robust technical support for key public security scenarios, including daily communications, major event security, social safety monitoring, and emergency response, thereby enhancing the intelligence and professionalism of public security operations.
