According to the statistics, about ninety percent of the network monitors apply the wired transmission. And the optical fiber is the main media. There are less than ten percent of the networks using the wireless transmission. Some data indicate that the wireless method is not ideal in the safeguard area. In recent years, countries are trying to develop the 3G, but it can not enter people’s life successfully because of the broadband and fee. More advanced techniques should be studied when the 3G communication technology is used. The forth generation of the wireless video is still at the experimental stage.

3G is mainly applied in the movable monitoring area with its unique advantages. Without the restriction within the time, place and occasion is always a diligent direction in the safeguard industry. With the permission of broadband, using the wireless transmission will be a breakthrough. However, 3G wireless monitoring still has so many shortcomings which can be filled up by 4G.

To begin with, the broadband and frequency of the wireless network are limited. The insufficient broadband can not secure the quality of monitoring picture. For example, the transmission rate of 3G network should be 144kbps when it is moving with high speed. If the CIF picture is secured, the rate must reach 512kbps. The immature technology and the insufficient broadband are the fatal elements of the wireless movable monitor. But 4G supports the down load speed of 100Mbps. Then, the wireless monitor can not be popularized widely because of the high fee. But the fee of 4G may reduce, which will make it more acceptable. Lastly, the current 3G video movable terminal is not totally suitable for the video monitoring, for example, the volume of the ordinary hard disk is too big to install. And the 4G will be more flexible.

The 3G network has almost formed, and developing the 4G networking is the next step for many countries. 4G network is able to fill up the shortcomings of 3G, although it still has its own weak points. Technology and capital are not the obstacles. We believe that the 4G network will have a bright future. The related integrated circuit is KDS200.
