In Lean’s wireless transmission equipment, wireless bridges are removed, as well as COFDM mobile transmission equipment and 3G/4G mobile image transmission equipment. Wireless bridges are the most used devices in wireless monitoring projects. However, generally speaking of vehicles and ships, it may be the first time to think of on-board transmission equipment and on-board equipment. These are all COFDM mobile transmission equipment, are low-frequency equipment, have a certain degree of diffraction, and can be implemented in a complex mobile environment. Wireless transmission. And if the distance cannot be determined, for example, if you want to transfer from this city to another city, you can use any 3G/4G signal and use 3G/4G mobile image transmission equipment to perform wireless monitoring anytime, anywhere.
However, the cost of COFDM mobile transmission equipment is very high and it is unbearable for general projects. The 3G/4G mobile graphics transmission equipment, the device itself is not high, but the consumption of traffic is also a headache. So, in the mobile environment, is it feasible to use wireless bridges for networking? The answer is yes. However, the same premise is to maintain an open environment. Vehicles moving within a certain range can use wireless bridges. The omnidirectional 360 degree angle is chosen, such as the LA-5810-N plus omnidirectional antenna. Another point to note is that under the same conditions, the same device, the greater the angle, the closer the distance that can be transmitted.
Let's look at the figure below:
This is the customer's needs. Install three network HD cameras on each car. The transmission distance is about 1 km. We designed the solution to concentrate the signals of the three cameras to the switch and then use a LA-5810-N. Wireless bridge external omnidirectional antenna for signal transmission.
In the monitoring center, use an external LA-5810-N wireless bridge to receive an omnidirectional antenna. After this is achieved, monitoring of the dynamics of the car can be carried out. And the overall cost is not high. Easy to install and easy to maintain.
The wireless transmission equipment of this kind needs to consider the following issues: the first cannot be blocked, and the second transmission distance cannot be too far. Third, the travel speed of vehicles and boats cannot be fast. For more detailed solutions, you can consult Levin personnel.
