What are the disadvantages of Lean COFDM wireless transmission equipment?

In many articles before the author, we can see the shadow of COFDM wireless transmission equipment. The wireless transmission equipment under COFDM technology has the powerful function that wireless bridge does not have. For example, it can be transmitted in a sheltered environment, has a certain degree of diffraction ability, and can be used in mobile. However, each product has its advantages and it is inevitable that there will be disadvantages. Below we analyze the disadvantages of COFDM wireless transmission equipment.

First, the price is high. More than ordinary wireless bridges.

Because the hardware and technology required for the COFDM wireless transmission device are several levels higher than the ordinary wireless bridge, the cost of the cost is much higher. Therefore, we can suggest that customers use wireless bridges to set up wireless monitoring systems for ordinary projects that can use wireless bridges. There are also many customers who come to carry a COFDM device to ask for the price. They do not know whether it is applicable or not. They are lamenting the high price.

Second, the bandwidth of COFDM equipment is very small.

Lean's COFDM equipment often explains when configuring to customers, COFDM transmission equipment can only point to point transmission. It can directly transmit video and audio, because it is usually used in people or equipments that need to be moved at all times. In order to ensure that signals can be received, omnidirectional antennas are often used. In order to guarantee the smoothness of video, in terms of design principles, The bandwidth is very small.

Third, the versatility of COFDM is not as broad as wireless bridges.

The frequency of COFDM is relatively small, and some low-frequency frequencies are used. The frequencies that can be used are also very small. There are individual frequencies that need to be applied to the relevant departments, so the versatility is small. And can not easily change frequency during use.

Fourth, the distance of COFDM wireless transmission equipment is also required.

From the previous description we can see that although COFDM wireless transmission equipment has a certain degree of diffraction ability and can be used under mobile conditions, it can not be far away because it is also the same as microwave transmission. The environment and the influence of the covering. So often customers will ask us, how far can Lean's COFDM equipment be transmitted, we can only answer, depending on the environment. Therefore, in the early stages of considering the use of such equipment, it is necessary to have a clear understanding of its own application environment.
