First, the user needs:
The plain about user needs more than 20 km radius within the industry to build a wireless Ethernet, the maximum antenna height to 50 meters, multiple remote data back to the fan center, the transmission rate request 200 500kbps, guaranteed data accuracy.
Second, demand analysis:
The user's wireless environment for the plain areas, the antenna height is relatively high, the wireless transmission conditions are better, but we consider the radius of 20 kilometers in the environment, it is inevitable that cities rise and fall of the situation, may caused by blocking of the wireless link. Requires accurate data and the user must ensure the stability of the wireless link. User equipment to use in different environments of wireless devices of their own stability, reliability, temperature and other requirements are relatively high. Based on the above analysis we choose iNET300 radio.
Third, the performance description:
iNET advanced frequency hopping spread spectrum radio technology, equipment, very strong anti-interference ability. Using special encryption, strong safety performance. Work on 340MHz radio frequency band, low frequency, has a strong penetration capability and diffraction, transmission distance, and because the station uses digital signal processing technology and FEC Forward Error Correction technology, it has a high signal reception sensitivity and can guarantee a reliable signal transmission, wireless environment is to make it more difficult to adapt to the case of the application. Radio air transmission rate of up to 512/256kbps, had to meet to the requirements of general industrial Ethernet, and the device provides an Ethernet port, two serial ports, you can also access a variety of different interfaces of industrial equipment, industrial equipment itself class products, can be applied to a variety of harsh environments.
