Background
Forest fires are very destructive. It will generate great damage to ecological environment and local economic development. Jiangsu communication system for forest fire prevention was constructed in the late 1980s, using analog radio, whose communication coverage failed to meet the current demand for forest fire prevention.
The Challenge
-
In recent years, the number of the province's forestry end-user has been in a rapid increase, which resulted in high traffic and serious channel blockage. In analog communication system, multiple frequencies at the overlap area among the same network or different networks interfered with each other, causing low efficiency. In addition, the old systems were badly damaged by lightning and other factors. In the event of fire, the old communication system couldn't meet the demands of dispatching because of its inaccurate positioning and poor communication.

该通信解决方案需要在整个高尔夫球场以及设施大楼和其他区域内提供良好的覆盖范围。大范围的人员和官员必须配备收音机，以提供清晰的语音通信和数据消息服务，包括记分员，裁判员，课程运营人员，保安人员，饮料和餐饮人员，以及许多志愿者来帮助举办赛事。
The Solution
After analyzing the customer’s existing communication system and development trend, Hytera built an emergency communication system based on communication network formed by DMR technology and wireless link networking technology to improve communications coverage and transmission rate, to ensure in the event of forest fires a variety of communication means can be used, thereby minimizing the loss caused by the forest fires. The whole project includes 9 provincial & municipal dispatch centers, 32 county dispatch centers, 74 fixed base stations and 46 mobile base stations.
The Results
With the newly-built Hytera digital communication system, Jiangsu forest fire prevention communication system forms a three-level dispatching network connecting the provincial, municipal and county dispatching centers together, which fully prepares for the fire prevention work.
IP-interconnect Base station network
The system supports network interconnect via the IP port of repeater to form a provincial forest communication system, which also realizes interconnect between base stations in forest areas and control centers, using digital wireless links.
Mobile emergency communication system
At the scene of an emergency, there are many personals with different wireless communications equipments. Frequency allocation becomes hard, and even the existing base station’s signal cannot cover the stricken area. With RD98X mobile repeaters, the signal coverage can get to the scene and can also be connected with the control center to ensure a timely and efficient commanding and dispatching.
Flexible networking & dispatching center
Characterized by C/S structure, modularized design and VoIP, Hytera dispatch system delivers the customer an enhanced dispatching and deployment platform with tailored communications network and control center.
