Wireless Private Network Solution for Forest Fire Prevention, Monitoring and Early Warning

I. Significance and Demand Analysis of Forest Fire Prevention System Construction

Afforestation is a basic national policy of China. However, with the intensification of global climate change and the increasing frequency of extreme weather events such as high temperature and drought, new challenges have been posed to forest fire prevention work. Forestry bureaus, fire prevention offices, forest police and other competent authorities are all entrusted with the supervision responsibility for forest fire prevention. Timely detection of fire hazards and deployment of resources for immediate disposal are the core of forest fire prevention work.

In accordance with the fundamental philosophy of forestry development focusing on protecting and improving the ecological environment, and implementing the forest fire prevention policy of prevention first, active elimination, we aim to achieve the goal of early prediction, early detection and early suppression of forest fires. From the perspective of protecting forest resources, safeguarding ecological security, maintaining social stability and promoting the sustainable economic and social development, we conduct scientific comparison and selection, resource sharing and overall planning for the construction of the entire project. We strive to build a comprehensive and effective forest fire monitoring network covering the jurisdiction to enhance the forest fire prevention capacity; ensure the smoothness of forest fire prevention command and communication, give full play to technological advantages, and provide support for the emergency suppression and command of forest fires.

A decisive factor for the success of forest fire prevention is the timely detection of fire alarms and rapid, accurate and rational analysis and judgment. Only in this way can correct decisions be made promptly, fire suppression measures be taken quickly, and the spread and escalation of fires be halted in a timely manner to minimize losses of national property and people’s lives. A host of professional technologies have emerged accordingly, including smoke and fire recognition, fire point positioning, and decision support. All these technologies rely on a stable and reliable high-bandwidth TCP/IP network for information transmission and sharing, and the transmission system must be highly dependable and consistent.

Another major challenge in building a forest fire prevention monitoring system is difficulty in power supply. Most fire prevention monitoring points are located at mountain-top watchtowers and similar sites. If mains power cables are used, the cost of laying cables from the foot to the top of a mountain often reaches millions of yuan, with prohibitive construction costs and timelines.

Based on Guoxin Longxin’s years of experience in forest fire prevention, China’s forested areas are mostly mountainous and hilly terrain with complex geographical conditions; many fire monitoring points are even inaccessible by road. Constrained by system costs, it is impractical to install monitoring points on every mountain top, resulting in relatively sparse distribution of forest fire prevention monitoring stations. Networking such points essentially requires communication between mountain tops, entailing ultra-long transmission distances of tens of kilometers. Laying optical cables in forested and mountainous areas is extremely costly and time-consuming, making wired transmission entirely unfeasible for forest fire prevention applications. Wireless technology is the only viable solution for networking forest fire monitoring points. However, ordinary WiFi or low-end wireless systems cannot meet the demand for transmission distances of 30 km, 50 km and beyond.

Furthermore, subpar environmental adaptability (lightning protection, rainproofing, wide temperature tolerance, corrosion resistance, etc.), low reliability and inadequate quality of system equipment will lead to frequent malfunctions. For integrators, this results in exorbitant maintenance costs in such harsh conditions. Currently, only a handful of mid-to-high-end carrier-grade or military-grade wireless systems in the industry—such as the iMAX Wireless Metropolitan Area Network (WMAN) private network system—can guarantee such high quality and reliability.

II. Design of Wireless Private Network Solution for Forest Fire Prevention, Monitoring and Early Warning

Given the unique geographical conditions of forests, wiring is extremely difficult and costly, making conventional wired solutions such as optical cables highly unsuitable. Meanwhile, telecom operators’ 4G/5G wireless networks fail to meet the requirements of forest fire prevention systems. Guoxin Longxin’s customized forest fire transmission solution based on the iMAX 5G wireless private network system (also known as the “wireless ad-hoc network system”) is the most practical and cost-effective solution available in the industry today.

The unique transmission requirements of forest fire prevention monitoring systems impose specific demands on the wireless system:

▶ Point Distribution

Field information collection stations are established at various high points in fire-prone areas to capture surveillance video footage within coverage, enabling 24/7 uninterrupted monitoring. Forested areas are typically vast, requiring wireless communication distances of tens or even hundreds of kilometers, while ensuring stable real-time transmission of multiple HD video streams and sensor data. Only ultra-long-range communication systems such as the iMAX WMAN can meet these stringent requirements for long distance, large capacity, HD video transmission and harsh environmental adaptability.

▶ Dynamic Monitoring

Supported by a wireless digital network platform, video footage and other data (weather, microclimate, etc.) are transmitted real-time and synchronously to district-level fire prevention monitoring centers, enabling live observation of forest dynamics. Only the iMAX wireless system—with low latency, high stability and superior reliability—can ensure smooth, real-time and stable video transmission.

▶ Emergency Plan Execution

In the event of a fire, the GIS (Geographic Information System) is used to extract relevant data for a clear understanding of the fire scene and accurate fire point positioning. Professional forestry database analysis generates feasible fire suppression plans, defining the deployment of personnel, machinery and materials, and identifying optimal suppression measures and evacuation routes. Such real-time, high-bandwidth and reliable network support cannot be achieved by carrier 4G/5G wireless technologies, but is fully guaranteed by the iMAX wireless system.

▶ Trend Analysis

Meteorological data collected by on-site small weather stations, combined with forest phenology and combustible material characteristic data, is comprehensively analyzed using expert database models to predict forest fire risk levels for specific regions. The seamless integration of data, video and voice transmission is a challenge for most wireless systems, yet multi-network convergence is a core advantage of the iMAX wireless system.

In the forest fire prevention industry, forested areas are mostly mountainous, hilly and sparsely populated, making wiring extremely difficult, costly and vulnerable to damage. Wireless transmission has thus become the mainstream solution. However, remote locations, harsh environments (wide temperature fluctuations, thunderstorms, ice and snow) and poor accessibility mean substandard product performance and quality will disrupt system operation and cause a sharp rise in later operation and maintenance costs. This is the fundamental reason why many users choose the iMAX WMAN system.

Due to the vast and sparsely populated nature of forested areas, communication distance and bandwidth stability are key pain points for forest fire prevention projects. “Wireless bridges” based on WiFi technology are inferior to the professional iMAX WMAN system in all critical performance metrics—including communication distance, bandwidth stability, multi-service bearing capacity, as well as quality and reliability. These advantages are the primary reasons why numerous industry users select Guoxin Longxin’s iMAX WMAN system. Additionally, the iMAX WMAN offers complete solutions for mobile communication scenarios such as vehicle-mounted wireless networking for command vehicles and even UAV wireless communication, enabling seamless integrated system design.

The combination of Guoxin Longxin’s wireless private network and lithium solar power supply system is a perfect match, addressing both the networking and power supply challenges in forest fire prevention monitoring system construction:
