GPRS Modem - RX 425





The GPRS (General Packet Radio Service) modem is a data transmission technology based on GSM (Global System for Mobile Communications). GPRS is different than traditional way of continuous transmission on channels. It transmits data by "Packet".

With the features of high-speed, always on-line, charge by using and etc, GPRS is then able to offer the protected and quick environment to go on-line and even low communication tariff. GPRS can access data by wireless terminal with the "MDVPN" which provides by the telecommunications company. In this way, GPRS can save the cost of building leased-lines, and also offers the function for "Group setup". Also, by checking on everything with GSM digital certification and exclusive VPN channel, GPRS can accept and transmit the important information with the great protection on real time.

  • To satisfy the demand of terminal control system.
  • Using the networks of telecommunication provides by the telecommunications company to building wireless terminal devices to monitor the important points.
  • To read the related data automatically and analyze it.
  • Terminal control or devices maintenance, decrease the manpower, maintenance time, and cost of building leased-lines.
