With the development of 3G technologies, the 3G wireless broadband is not only widely applied in the civil field, but also in the industrial field. Some manufacturers try to apply the 3G wireless broadband technologies to manage the regional where is poor and large, because the coverage is wide and the cost performance is high. The rescuers can not reach the place when the accident is happening on the expressway, because the expressway is long and having bridges. The 3G dispatching system will help a lot in the expressway accident processing and rescue. The specific advantages make this technology popular in many fields. I will list some of the advantages in the next paragraph of the article.

Firstly, the coverage of 3G wireless broadband is generally in proportion to the public area. The broadband is able to reach wherever the user goes. Secondly, the 3G wireless broadband is more flexible than the other broadband. The cost of the terminal can be cut by expanding the ranges of options; meanwhile, the phone with the dispatching system also can join in the whole network. Thirdly, the specific network can be replaced by the public network. The cost can be saved by the application of public network.

There are few companies provide the 3G dispatching system and the related functions at the present time. Then let us get to know about the function of this dispatching system.

First is the movable urgent meeting. The commander can establish a meeting by the 3G portable terminal. The commander does not need to wait for the report from the front stage before making the decision. The meeting can be established only when the specific number is dialed, therefore the authority can not be overstepped by other people. Secondly, more accurate decision will be made when the accident situation is sent by the 3G portable terminal device. Thirdly, the order can be given by the form of image and video. Workers can contact with each other in the multimedia form with the portable terminal. Fourthly, the positioning function also helps to judge the accident place which is hard to be found on the long expressway. The place will be displayed on the screen, making the rescue to be efficient. The related integrated circuit is L3000N-C6
