When to be several kilometers to tens of kilometers away from each other to connect the remote site communication, 3511 using wired methods, must be set up long-distance cable or dig a long cable trench, the project cycle may require several months of time, and the use of digital transmission module to establish a dedicated wireless data transmission, only need to set up the appropriate height of the antenna, the project cycle requires only a few days or a few weeks can be! In contrast, the wireless way can quickly set up a communication link, the engineering cycle is greatly reduced.

The limitations of wired communication is too large, in some special applications, such as encountered in the mountains, lakes, forests, and other special geographic environments or moving objects and other wiring is more difficult to apply the environment, the wired network will be wired project has a strong constraints, and the establishment of a dedicated wireless data transmission module with the wireless data transmission module will not be subject to these limitations, so that with the wireless data transmission module to establish a dedicated wireless data transmission will have a better adaptability than the wired communication. So the wireless data transmission module to establish a dedicated wireless data transmission mode will not be subject to these restrictions, so that the data transmission mode will have a better and wider adaptability than wired communication, almost not subject to geographic limitations.

3511 After users set up a communication network, often because of the system needs to add new equipment. If the wired way, the need to rewire, construction is more troublesome, and there is the possibility of destroying the original communication lines, but if the use of wireless data transmission radio to establish a dedicated wireless data transmission, only the new equipment and wireless data transmission radio connected to the expansion of the system can be achieved, compared with a better scalability.
