The GDWP5R is a high-speed data radio designed for long-distance and high-performance data wireless modems with 5W output power. It uses GFSK modulation to provide high frequency resource usage and anti-interference performance is the first equipment for industrial control of users in important fields such as water conservancy, electric power and oil fields.
Because of its high stability and possibility, data radio is used by many suppliers such as PLC, RTU, MHI, and DCS to monitor and control key assets. It can be used in small or large scale telemetry systems, especially for mobile and temporary access point applications, or as an uneconomical and impractical alternative to cabling.
