PMR Cluster Solution for Highway

Background

Nowadays, the information of highway is in a rapid development period in many countries, especially the application of information based on PMR. But because of the large scale of highway, the complication of environment and some features that we are facing the following challenges:
* Long-term operation, plant aging, more fault point, high maintenance cost.
* Lack of base station, low coverage, poor voice quality.
* Lack of channel, no connect between departments.
* Without conglomeration function, no flexible group management, delayed cross-level command.

Solution

Combining GPS(Global Positing System), mobile communication network, GIS(Geographic Information Service) , computer network communication with data processing technique, this solution develop on the basis of WCDMA communication system that using the supervising and scheduling system as the display platform. Integrate data from vehicle with GPS which running in the highway and Intercom terminal equipment with the supervising and scheduling system, providing a platform for each vehicle and staff in deployment, rescue, emergency and other applications.

Advantages

Adopt the method of public cluster intercom and PTT public cluster communication technology to achieve the function of digital trunking communication and deployment based on wireless public mobile network. No need to reform or upgrade the public network, or built network. Using the abundant resources of wireless public network, excellent planning and maintenance, directly connect to the network. Realize the wide area communication scheduling in low cost without applying for frequency.
