Demand Analysis    


Forest fire is the most dangerous enemy of forest and the most terrible disaster of forestry. It will bring devastating consequences to forest. Moreover, the timing of forest fires is ever-changing, and firefighters are participating in forest firefighting, and the dangers faced are endless. Due to the forested trees in the forest and the complex terrain, the 4G network generally cannot be covered. When a dangerous situation occurs, due to poor communication, the situation in front cannot be transmitted to the command center, and the command center cannot issue dispatch commands in time, thereby increasing the number of accidents. Probability.


Therefore, based on the importance of forest fire prevention, it is very necessary to build a forest fire emergency communication network based on wireless broadband Mesh self-organization network at the front end and backhaul back based on LTE broadband private network. The front-end construction of a wireless broadband Mesh self-organizing network system can realize real-time wireless audio and video and data multi-hop transmission between the fire rescue team and the command vehicle to ensure smooth communication in the forest fire prevention and disaster relief process.


Solution

 

IFLY's self-developed wireless broadband MESH ad hoc network equipment is a new generation of communication technology products based on software radio architecture. The device has a multi-hop self-organizing network function, which can cover areas that are difficult to reach by traditional devices (such as valleys and canyons) through "relay transmission"; at the same time, the device is a centerless co-frequency device, and the command center and field staff can At the same time, access the same network to ensure smooth communication and communication between the two parties, so as to achieve unified command. The information of the field command is transmitted back to the general command center through the 4G LTE private network and the 4G public network communication network for coordinated operations.

 

IFLY's MESH series of radios are rich in types, and the current product forms include: individual soldier radios, vehicle-mounted backpack radios, MESH base stations / relays, and drone airborne radios. They are highly adaptable, practical, and easy to use. It can quickly form a decentralized network without relying on public facilities (public power, public network, etc.) through free networking between MESH self-organizing network products.


Design

MESH


1. Choose a suitable location in the forest area, install an appropriate amount of long-distance wireless Mesh base station on the iron tower, and take full advantage of the high mountainous terrain. The MESH base station can be deployed in the same site as the public network base station and interconnected. Through multi-hop relay and relay forwarding, the collected forest and forest area data and image information can be returned in real time around the clock, and can also be transmitted back to the remote command center through the 3G / 4G public network, which is convenient for real-time viewing and scientific analysis.

2. Deploy vehicle-mounted MESH nodes on the command vehicle and forest patrol vehicle to quickly enter the forest forest area, which is convenient for information collection, patrol monitoring and command dispatching, and provides wireless network support for forest forest security personnel;

3. The security officer carries the individual soldier's MESH node on foot, and can go deep into the forest forest area to perform first-line tasks. High-definition video images are returned in a timely manner as much as possible, providing a comprehensive and clear live real-time image to the rear platform.

4. The drone is equipped with an airborne self-organizing network node device, which can not only further expand the wireless coverage, reduce the coverage blind area, and improve the quality of video backhaul; but also combine the air mobile surveillance with the ground fixed surveillance, and complement each other's advantages. The formation of a ground-space "stereoscopic" monitoring network effectively increases the visibility of the monitoring area.


Program Features

 

Feature 1: High-bandwidth, two-way transmission

Adopt software radio architecture, support COFDM waveform, high throughput, up to 80Mbps, to ensure large bandwidth transmission, multi-channel video simultaneously bidirectional transmission.


Feature 2: Reliable self-organizing and self-healing network

The MESH wireless network does not depend on the base station, has the excellent characteristics of self-organizing network, self-management, self-repair and self-balancing, supports multi-point jumper, and meets the network transmission under non-line-of-sight conditions.


Feature 3: All-IP transparent transmission and converged communication

It adopts all-IP transparent data transmission, supports end-to-end TCP / IP protocol, and can be easily connected with superior network systems to form a variety of dedicated command application systems. MESH ad hoc network equipment conforms to standard network protocols and has rich interfaces. It can also be connected to public basic networks, such as fiber optic networks, wired networks, and 4G LTE networks.


Feature 4: Full-duplex VoIP voice intercom

MESH ad hoc network equipment integrates a non-central IP voice module to achieve voice communication between vehicles. Compared with other intercom solutions, the voice intercom function is more suitable for a decentralized network architecture. Any failure will not affect the voice communication between other nodes, and the transmission range is not limited by the wireless performance of a single node. Support real-time voice intercom, support high-definition video real-time transmission, support WIFI and access to a variety of application terminals.


Feature 5: Security and encryption

Customers have extremely high requirements and sensitivities to network security and data encryption. It is precisely because of the particularity of the environment used and the participation in the project that IFLY regards network and data security as the core issue of top priority.
