The GTM-204M Series is an industrial 4G LTE and Quad-band GSM modem with RS-232 and USB interfaces that work at frequencies of 4G LTE and 3G WCDMA and 2G GSM. The modems utilize the 4G/3G/2G networks to transfer data. The features of the GTM-204M Series allow a variety of PLC and PC applications to take advantage of SMS and 4G/3G/2G connectivity.

The I-8213W-4G series are industrial 4G LTE modules with GPS function that work on frequencies of FDD LTE B1/B3/B5/B7/B8/B20(I-8213W-4GE) or FDD LTE B1/B3/B8 and TDD LTE B38/B39/B40/B41(I-8213W-4GC). WCDMA 850/900/2100 MHz and GSM 850 MHz, EGSM 900 MHz, DCS 1800 MHz, PCS 1900 MHz. These modules utilize the 4G, 3G or GSM/GPRS network for convenient and inexpensive data transfer from remote instruments, meters, computers or control systems in either live data or packet data. I-8213W-4G has the integrated TCP/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 I-8213W-4G, the systems can be SMS, GPRS and 4G connection applications with our PAC series like WinPAC-8000, LinPAC-8000 or XP-8000.
