Advantages
Comparatively speaking, the wireless data transmission module to establish a dedicated wireless data transmission method than other methods have the following advantages, the following describes the DATA-6106 wireless data transmission module to establish a dedicated wireless data transmission method compared to the advantages of wired communications.
Low cost
The establishment of wired communications must be set up cable, or digging cable trench, so it requires a lot of manpower and material resources; while the establishment of a dedicated wireless data transmission using wireless data transmission radio does not need to set up cables or digging cable trench, you only need to connect the wireless data transmission radio in each terminal and set up the appropriate height of the antenna can be. Compared with the wireless data transmission module to establish a dedicated wireless data transmission mode, saving manpower and material resources, the investment is quite economical.
Of course, in some short distance data communication system, the wireless communication method is not lower cost than the wired way, but sometimes the actual field environment is difficult to wire, customers according to the needs of the field environment or will choose the wireless way to realize the communication.
Short construction period
When the distance of several kilometers to dozens of kilometers away from each other to connect the remote site communication, using the wired way, you must set up long-distance cables or dig a long cable trench, the project cycle may take several months of time, while the digital transmission module to establish a dedicated wireless data transmission, only need to set up the appropriate height of the antenna, the project cycle only takes a few days or weeks, can be, the wireless way to communicate quickly. In contrast, the wireless way can quickly set up a communication link, the engineering cycle is greatly reduced.
Good adaptability
The limitations of wired communication 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, the wired network will have a strong constraints on wired wiring project, 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 module to establish a dedicated wireless data transmission will have a better adaptability than the wired communication, and the wired network will have a better adaptability than the wired communication. The data transmission mode will have better and wider adaptability than the wired communication, which is almost unlimited by the geographic environment.
Good scalability
After users set up a communication network, often because of the system needs to add new equipment. If the wired way, you need to rewire, construction is more troublesome, and there is the possibility of destroying the original communication lines, but if you use the wireless digital radio to establish a dedicated wireless data transmission, only the new equipment and wireless digital radio connected to the expansion of the system can be realized, compared with a better scalability.

Data Transmission
Data transmission can be simply divided into wired (including the erection of fiber optic cables, cables or leased telecommunications lines) and wireless (divided into the establishment of a dedicated wireless data transmission system (433MHZ band and 2.4G band) or borrowed CDPD, GSM, CDMA and other public networks and information platforms) two broad categories of ways.
Application areas (application examples):
Users are first concerned about the transmission distance, the distance is actually not a problem. Near the use of 433MHz band wireless data terminal DTD433, far from the use of GPRS transparent transmission data terminal DTP_S09F. The so-called & ldquo; near ”, refers to 3 kilometers or less can be covered by the majority of factories and mines; the so-called & ldquo; far ”, refers to the communication distance of more than 3 kilometers, or even across the different geographic areas as well as different countries, good! In China mobile network has covered the world, so the distance is not a problem. The combination of DTP_S09F and DTD433 can meet most of the wireless measurement and control requirements.
