The GTM-201-3GWA is an industrial Tri-band 3G WCDMA cellular modem with RS-232 and USB interfaces working on frequencies of Tri-band WCDMA 2100/1900/850 MHz, and Quad-band GSM 850/900/1800/1900 MHz. The modem which supports up to 7.2Mbps downlink speed and 5.76Mbps uplink speed services can utilize the 3G/GSM/GPRS network for convenient and inexpensive data transfer from remote instruments, meters, computers or control systems in either live data or packet data. The GTM-201-3GWA enables internet connection over 3G, when 3G service is available. It automatically selects 3G or GPRS continue to work.
Moreover, the GTM-201-3GWA has the integrated TCP,UDP/IP stack so that even simple controllers with serial communications ports can be connected to the modem without the need for special driver implementation. With the features of GTM-201-3GWA, the systems can be SMS and 3G/GPRS connection applications with various PLC and PC. Moreover, with the voice interface, these modems can also be applied to the alarm system with sounds.
