4G Gateway
The GTM-201-3GWA is a industrial Tri-band 3G and Quad-band GSM modem with RS-232 and USB
interfaces that work at frequencies of UMTS 2100 / 1900 / 850 MHz and GSM 850 MHz, EGSM 900
MHz, DCS 1800 MHz , PCS 1900 MHz. The modems utilize the 3G or GPRS network to transfer data.
The features of the GTM-201-3GWA allow a variety of PLC and PC applications to take advantage of
SMS and 3G or GPRS connectivity. The voice interface allows the modem to be also applied to alarm
systems with sounds.
