Product Overview


  Wireless concentrator and other equipment for water meter


Wireless remote communication function

The terminal embedded GPRS/CDMA wireless data communication module, which uses GPRS/CDMA wireless data service to read the terminal data. GPR / CDMA wireless data communication follows the relevant standards of international, national and wireless communication products network detection organizations. Drawing on the advantages of similar product design ideas in foreign countries, the company has integrated the past years of research and development experience of collecting terminal products, with high reliability, large capacity, low delay, good openness, high reliability, large capacity, low delay, and good openness. The GPRS/CDMA wireless data communication of the terminal is by means of TCP/IP or SMS, when using TCP/ IP mode communication terminal can be configured to TCP mode or UDP mode.
