Introduction
China is a country with many lakes and a very long coastline. Overfishing will seriously affect the marine ecological chain, severely damage the marine ecological environment , and threaten the livelihood of coastal residents.

Market Segment
Monitor illegal fishing and patrol rescue
Background
In order to allow fish in the ocean to have sufficient time to reproduce and grow, to protect the growth of fish, and to prevent the depletion of fish stocks, relevant departments will set up a fishing moratorium. During the specified time, no one is allowed to catch fish in waters or sea areas. However, illegal fishing occurs from time to time during the fishing moratorium, and how to help the Ministry of Fisheries supervise illegal fishing activities has become the main task of the IWAVE wireless communication system.
Challenge
Unusual fishing occurs from time to time, mainly because the monitored waters have complex topographical environment, are far away from the monitoring center, the public network signal is poor, and there are islands blocking the middle of the waters, which makes the transmission distance of the monitoring video backhaul very limited , resulting in the inability to detect illegal fishing in time. For fishing and other illegal activities, it is impossible to leave evidence and call patrol ships and law enforcement officers in time to deal with them.
The prohibited waters are long and wide, and the law enforcement environment is harsh. Illegal fishing mostly occurs at night. Difficulties in water law enforcement arrests, difficult evidence collection, and many law enforcement safety hazards are huge challenges in the process of law enforcement . It is particularly important to use IWAVE wireless transmission and video scheduling systems to achieve innovative and efficient fisheries management models.
Solution
In order to strengthen fishery law enforcement, curb the occurrence of illegal fishing and other acts, and ensure the effective protection of the ecological environment, IWAVE 's wireless communication company has designed a new model of "drones + patrol boats" integrated water monitoring based on local conditions. The Visual Command And Dispatching Platform is fully deployed and controlled, and law enforcement personnel respond quickly, effectively alleviating problems such as inadequate supervision of key waters and low accuracy of suspects' positioning, and achieving efficient and precise supervision of fishing bans.
This solution needs to deploy and control the water area. Since the distance is as long as 47 kilometers , and there are islands and mountains in the middle, it is necessary to use IWAVE high-power MESH wireless high-bandwidth video products, and Long Range MIMO IP MESH Link for UAV and cooperate with multimedia dispatching the command system implements a 24/7 monitoring plan.
Law enforcement officers on patrol ships are also equipped with handheld MESH devices and Body Worn Camera that can be used with this system, and wireless handheld devices can work uninterruptedly for 8 hours, connect to the monitoring network in real time and support the vessel to expand the patrol range. When illegal fishing is detected, law enforcement officers can quickly use the body camera with an infrared camera to record and transmit back video from the scene.
The scheme diagram is as follows：
In this system
Smart handheld terminals can wirelessly transmit water area information. Handheld base stations and vehicle-mounted MESH base stations can use flexible self-organizing networks to return or relay video and data through various high-power self-organizing network MESH products, and can independently find the most The optimal path effectively reduces the long-distance transmission delay. After the business data (voice, video, incident location and other data) is transmitted to the control center, it can be displayed on-site through the dispatching console and dispatching instructions can be issued.
IWAVE multimedia command and dispatch system is an on-site command and dispatch system specially built by our company for monitoring and emergency rescue based on the industry-leading broadband ad hoc network technology with fully independent intellectual property rights.
The system integrates on-site broadband multimedia command and dispatch software platform, portable command station, vehicle-mounted station, backpack station, smart handheld terminal and other equipment. ), providing a new, reliable, timely, efficient and secure communication solution.
Benefits
The system adopts high-power MESH wireless communication products, which has the characteristics of non-central ad hoc network. It can be carried by ships and vehicles, or fixedly installed on high places on islands for relay backhaul to expand the transmission distance. Easy to deploy, quick to start and apply. It supports multiple functions such as PTT voice trunking, multi-channel video return, video distribution, map positioning, etc., and one system meets the full business needs of the emergency scene.
The advantages are as follows:
It is easy to use and quick to deploy, and it is specially tailored for the application scenarios where every second counts at the emergency site.
There is no center and self-organization, and there is no need for multi-network integration in the background; at the same time, it can support voice and video, and each terminal can freely carry out business communication according to its needs.
The local command system does not depend on cloud servers. However, it can also be connected to the cloud through various methods such as 4G/5G public network and satellite communication, and the on-site audio, video, pictures and other information can be sent back to the rear command center .
The network has strong invulnerability. The local dispatching station is offline, which does not affect the voice function between devices on the network, and voice communications such as group calls and individual calls can still be performed.
