At present, the Guangdong Provincial Public Security 350M radio dispatch system is with multi-standard (analog, TETRA and PDT), multi-carrier bandwidth (25KHz, 12.5KHz), multi-frequency using mode (changing frequency across base stations, no frequency changing across base stations) (synchronous broadcast)). More than 200 public security radio dispatching networks have been built. Except for the PDT system, other systems are difficult to be effectively interconnected. In addition, the previous 350M TETRA digital trunked systems in some cities of Guangdong Province are still in the normal using cycle. They will not be replaced by the PDT system in a short period of time. The networks of two standards will coexist for a long time. How to develop the PDT system and fully utilize the existing TETRA system to protect investment and reduce resource waste has presented a new challenge to the construction of the radio dispatch system of provincial public security department.
Customer ValueEastcom unifies the communication platform through building the province's police PMR system in the provincial Public Security Bureau level, realizes the interconnection between different equipment manufacturers, different technical standards and different frequency points of the Guangdong public security radio private network on the basis of not changing or making less change to the original police radio system, and solves the scheduling and communication interconnection problems between different standard (analog, PDT and TETRA) radio trunked systems, and the interconnection between mainstream manufacturers' PDT systems. It provides a strong guarantee for the long-term evolution and cross-system actual use of the public security radio dispatching system in Guangdong Province.
