Global Tech GT-DTU Series DTU(Data Transfer Unit) is Low power
consumption, Wide temperature,industrial wireless data transmission
equipment; it provides users with transparent TCP remote wireless
data
transmission or transparent UDP wireless remote data transmission
through 2G/3G network. The equipment adopts high-powered X86
processor and embedded with real-time operating system as software
support platform. Large memory, built-in TCP / IP protocol stack with
Intellectual property rights, supports auto-dial, the transparent data
transmission, routing, remote wake-up functions for users to quickly
and
efficiently build a wireless DDN network system to provide improved
data transmission capabilities.
