Description of wireless bridge monitoring system using wireless bridge

A lot of shipping, ferries running on the sea, need to return real-time driving conditions to the monitoring center.

Mobile wireless video surveillance, like COFDM, solves the problem of occlusion and mobile transmission. However, the high COFDM price is an aspect. On the other hand, most COFDM products generally transmit non-digital signals, and the general bandwidth that can transmit digital signals is lacking. Many large vessels are generally monitored in all directions and several cameras are installed. This can only take into account the wireless bridge. But like all wireless bridges, the requirements are in an open environment. There is generally no shelter on the sea. Wireless bridges can transmit tens of kilometers or more in practical applications, but they are transmitted at fixed points. That is, directed delivery in our terminology. Wireless bridges have a corresponding angle. The ship is in the middle of a move. If you use directional transmission and reception, the ship will always go and it will deviate. Then, there will be no signal reception. Therefore, in the design, it is recommended to use omnidirectional transmission and directed reception for networking. The next step is to look at the trajectory of the ship's movement, within the range of angles, as a condition for the configuration of the receiving bridge. In view of such restrictions, in general, if the required bandwidth of the vessel is large, the transmission distance cannot be too far when the wireless bridge is used for transmission. The larger the angle of the wireless bridge is, the wider the coverage can be, but the closer it is to a straight line. It is generally better to achieve around 1-5 km. If it is in the ten kilometers, if the bandwidth is not large, only a few megabytes, then the use of Lai'an LA-6800N COFDM bridge can also be transmitted.

Of course, the above is only a combination of more common situations. If you are not sure, you can contact L&A directly and give you the most professional advice.
