The solution was to manufacture an Ingress Protection 67 rated custom aluminium housing for the router. The cabling that exits the router and terminates elsewhere (i.e. Power, Ethernet, Antenna, etc.) was also upgraded providing the customer with a package which fully meets the IP65 requirements.
Such IP65 certified products are exceptionally durable, corrosion-resistant and able to withstand mechanical abuse as well as exposure to chemicals, water, extreme temperature changes and high-vibrations.
