The wireless datatransmission module is a modular product of data transmission radio. It refers to ahigh-performance professional data transmission station realized by DSP technologyand radio technology. The use of digital radio has evolved from the earliestkey codes, telegrams, analog radios and wireless MODEMs to current digitalradios and DSPs, software radios; transmission signals are also from code,low-speed data (300 to 1200 bps) to high-speed data (N*) 64K ~ N * E1), cantransmit services including remote telemetry data, dynamic images and so on.
Wireless datatransmission is widely used in vehicle monitoring, remote control, telemetry,small wireless networks, wireless meter reading, access control systems, cellpaging, industrial data acquisition systems, wireless tags, identification,contactless RF smart cards, small wireless data terminals, security Fireprotection system, wireless remote control system, biological signalacquisition, hydrometeorological monitoring, robot control, wireless 232 datacommunication, wireless 485/422 data communication, digital audio, digitalimage transmission and other fields.
The establishment of wired communication methods must erect cables or digtrenches, so it requires a lot of manpower and material resources. The use ofwireless digital radio stations to establish dedicated wireless datatransmission methods eliminates the need to erect cables or dig cable trenches,and only needs to be connected at each terminal. Wireless data transmissionstations and antennas with appropriate heights are all available. In contrast,the use of wireless data transmission module to establish a dedicated wirelessdata transmission mode, saving manpower and material resources, investment isquite economical.
Of course, in some close-range data communication systems, wirelesscommunication methods are not cheaper than wired methods, but sometimes theactual field environment is difficult to route, and customers will use wirelessmethods to achieve communication according to the needs of the on-siteenvironment.
When remote stations connecting distances of several kilometers to tens ofkilometers are to be connected to each other, it is necessary to installlong-distance cables or dig long cable trenches in a wired manner. Thisengineering cycle may take several months. The use of digital transmissionmodule to establish a dedicated wireless data transmission method, only need toset up an antenna of appropriate height, the engineering cycle can only take afew days or weeks, in contrast, the wireless way can quickly set up acommunication link, engineering The cycle is greatly shortened.
The limitations of wired communication are too great. When encountering specialapplication environments, such as encountering special geographicalenvironments such as mountains, lakes, and forest areas, or applications wherewiring is difficult, such as moving objects, the wired network will be Wiringengineering has a strong constraint, and the use of wireless data transmissionmodule to establish a dedicated wireless data transmission method will not besubject to these restrictions, so the use of wireless data transmission moduleto establish a dedicated wireless data transmission method will be better thanwired communication. Adaptability is almost unrestricted by the geographicalenvironment.
After a user sets up a communication network, new devices are often addedbecause of the needs of the system. If the wired method is used, it needs to bere-wired, the construction is troublesome, and it may damage the originalcommunication line. However, if the wireless data transmission station is usedto establish a dedicated wireless data transmission method, only the newlyadded equipment and the wireless digital transmission station are needed.Connected to achieve system expansion, compared to better scalability.
