The refinery plant is large and hosts a lot of facilities. At the storage tank farm, the probability of safety accidents, such as fire, explosion, and poisoning, is high. For safe production, efficient operation, as well as production accident prevention and disposal, the communication system must be well planned and deployed.
The storage tank area usually is at the far end of the communication tower and the remote cabinet is set up with an anti-explosion structure. Due to the shielding of signals by the tanks, there might be blind areas of signal coverage.
