gprs gateway page

Serial to GPRS Gateway enables various kinds of legacy devices with serial port to communicate over cellular network and the internet easily . It works as a cellular modem by constructing a smooth data tunnel between Host and Remote side, ensuring an efficient communication for data transmission and remote device management.

Its applications vary from factory automation, environmental monitoring and remote device management etc. It is supplied with simple Software interface that streamline application development process, freeing system integrators from dealing with complex communication protocols of GPRS/CDMA and the Internet. Users do not need to change the existing system, saving cost and time for field maintenance, and making it a perfect solution for data transmission.
