Applications point and diagram:

  • Temperature : The wireless bridge section working temperature range: -30 ° C-70 ° C. If the temperature outside this range may cause the wireless bridge does not work.
  • Wind speed – wireless bridge to normal work of the wind speed range :0-90MPH, if the wind speed up to 125MPH have been resistant also. Therefore, you must consider the largest known installation point of wind and wind direction, and the installation point should be such as: poles, posts or towers like the mounting bracket.
  • Lightning – wireless bridge products, this section includes built-in lightning protection device, but you must ensure that equipment, mounting bracket, cables are fully grounded.
  • Transmission range – this professional long distance wireless bridge for the remote transmission , the data in the basic mode, the transmission range of 0-30 km, in Turbo mode, the transmission range of 0-14 km.
  • Rain-proof : Waterproof design , it can good work with long time rain ,also did not affect the signal transmission quality. But you may need to use the seal with Ethernet interface, once the moisture into the interface will reduce the product’s performance or even the bridge does not work.
