The AX-SFJK is a single chip solution for a node on the Sigfox network in RCZ3 region. In the Internet of Things the domain of nation wide coverage and ultra low power consumption for smallest amounts of data can not be addressed by established standards such as GPRS or LTE. This void is now filled by Sigfox, the ultra low power cellular connectivity solution. Add Sigfox functionality for up-link and down-link to any existing system at the cost of 20x13 mm2 PCB area. It can also be used as a single chip solution that control small sensor nodes. The AX-SFJK device is fully programmed for immediate operation as a Sigfox node.
