SAMX is the latest modem from Intercel, featuring the new Cat M1 and NB-IoT 4G technologies. These new technologies are designed for low power 4G connectivity and are specifically aimed at M2M, IoT and metering applications. Intercel was the first company to offer a remote meter reading modem in Australia and we have continued to design our own solutions in Australia. SAMX represents the latest and most modern version of our proven and reliable SAM modems.

The SAMX is fitted with a USB port and a Serial RS232 Port for connectivity and can be controlled using AT Commands. The SAMX is running Intercel’s TCP/IP Stack for remote connectivity.SAMX is available in two versions supporting different frequency bands, allowing the end user to select the modem that suits their requirements.
