• The remote operation of water stations while ensuring a secure and reliable transmission of data from the RTU to the control room
• Reliable operation of the gateway under the high temperature of the Gulf cities and the high humidity found in water stations
• Backward compatibility of the data sent from the RTU with the SCADA system
After site surveys, the 3G gateway was provided by Xceltra for NWC as it suited and met the challenges facing the project through:
• Secure communication with VPN and firewall
• Support for several encryption protocols for secure communication
• Built-in Modbus gateway eliminating the need for extra hardware to communicate with the SCADA
• 3G Gateway utilizes the high speed 3G networks (HSPA+) with quad band frequency support
• A wide range of operating temperatures from–25 to +70 °C
• The ability to operate reliably in humidity from 5 to 85 % RH
