1900/65A-01-01-01-00-00 In some short-distance data communication system, the wireless communication method is not lower cost than the wired method, but sometimes the actual field environment is difficult to wiring, the customer according to the needs of the field environment or choose the wireless way to realize the communication. Equipment maintenance is easier to realize, wired communication link maintenance needs to be checked along the line, there is a failure, it is generally difficult to find out the point of failure in time, and the use of wireless data transmission module to establish a dedicated wireless data transmission only need to maintain the data transmission module, there is a failure can quickly find out the reason, to restore the normal operation of the line.

1900/65A-01-01-01-01-00-00 good adaptability, wired communication limitations are too large, in some special applications, such as mountains, lakes, forests, and other special geographic environments or moving objects and other wiring is more difficult to apply the environment of the wired network wiring project has a strong constraints, and the establishment of a dedicated wireless data transmission module with wireless data transmission will not be subject to these limitations, so the wireless data transmission module will not be used to establish a dedicated wireless data transmission mode, so it is necessary to maintain the digital transmission module can quickly find out the cause of the failure to restore normal line operation. Transmission mode will not be subject to these restrictions, so that the wireless data transmission module to establish a dedicated wireless data transmission mode will be better than the wired communication has a wider range of adaptability, almost not subject to geographical restrictions.

1900/65A-01-01-01-01-00-00 good scalability, after the user set up a communication network, often because the system needs to add new equipment. If the wired way, the need to re-wire, 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 to a better scalability.
