Product Details

AX-SIGFOX Radio Modem for SIGFOX Networks

The AX-SIGFOX is an ultra-low power wireless transceiver designed to link a remote sensor node with a SIGFOX base station. It provides both up and down-link functionality for remote, low-power, low data-rate sensors operating as part of the Internet of Things (IoT). The data rate is low and packets containing up to 12 bytes of payload are transmitted or received at widely spaced intervals.
