Designed for tight integration into subscribers' terminals, the GDCA20 has 4G LTE and a powerful cellular RTU that provides a versatile platform. It can be remotely connected, making it ideal for transmitting data and control messages in medium-range (1-10km) applications. Ability to monitor and control assets of various lines, such as remote meter reading (gas, electricity, firepower), remote control of water distribution, remote control of irrigation systems and environmental monitoring.
