The advantages of cell module in industrial control area

Data transmission can be simply divided into wired (including the erection of optical cable, cable or leased telecom line) and wireless (including the establishment of a dedicated wireless data transmission system or borrowing CDPD, GSM, CDMA and other public network information platform) two categories of ways.

In comparison, using wireless data transmission module to establish a dedicated wireless data transmission mode has the following advantages over other methods. The following is an introduction of the advantages of using wireless data transmission module to establish a dedicated wireless data transmission mode compared with wired communication.

1. Wireless communications relatively cheap

Cable communication must be set up, or dig cable trench, so it needs a lot of manpower and material resources; Using a digital radio station to set up a dedicated wireless data transmission mode does not require laying a cable or digging a cable trench. In contrast, the use of wireless data transmission module to establish a dedicated wireless data transmission mode, saving manpower and material resources, investment is quite save.

2. The construction period of wireless communication is short

When within a few kilometers to tens of kilometers distance to a remote site connection communication each other, with the method of cable, must set up a long cable long in cable trench, or mining may need several months the project cycle time, and with digital module build special-purpose wireless data transmission way, only need to set up appropriate height of antenna, the project cycle, only need a few days or weeks can, by contrast, can quickly establish a wireless way communication link, shorten the project cycle.

3. Good adaptability of wireless communication

Limitations of wired communication is too large, in case of some special applications, such as mountains, lakes, forests and other special geographical environment and the application of moving object, such as wiring difficult environment, to the wired network wiring project has extremely strong further reading.in, wireless data transmission module and establishing special will not be restricted by the wireless data transmission mode, so in wireless data transmission module build special-purpose wireless data transmission way to more extensive adaptability than the wired communications have better, almost without being limited by the geographical environment.

4. Good expansibility of wireless communication

After the user has set up a communication network, new equipment is often added due to the need of the system. If adopt the way of the cable, need to wiring, construction more troublesome, but also could undermine the original communications lines, but if the special set up by adopting the wireless digital radio wireless data transmission way, just put the new devices connected to wireless digital radio can realize the system expansion, in contrast with better extensibility.

5. Wireless communication equipment is easier to maintain

The maintenance of the wired communication link needs the inspection along the road, and when there is a fault, it is generally difficult to find out the fault point in time. However, it is only necessary to maintain the data transmission module to establish a special wireless data transmission mode by using the wireless data transmission module. When there is a fault, the reason can be quickly found out and the normal operation of the line can be restored.
