Developed for use with long-life, battery-powered sensors, the IEEE® 802.15.4 standard is defined for operation in the unlicensed Industrial Scientific and Medical (ISM) bands used worldwide. As the number of wirelessly connected and extremely power-conscious applications using this standard continues to rise, designers need flexible and reliable solutions with features that will extend battery life for multiple years.

Our low-power SAM R30 series of products utilize IEEE 802.15.4 in the sub-GHz channels of the ISM band. Designed to operate between 769 and 935 MHz, SAM R30 devices deliver superior range when compared to 2.4 GHz networks. Their ultra-low-power sleep modes, which consume less than 1 uA, also enable your products to meet the standard’s defined ability to sleep virtually forever. 

Well suited for use in connected home, smart city and industrial applications, these solutions are available as the SAM R30 System in Package (SiP) devices and the SAM R30 Module, which work in conjunction with our proprietary MiWi™ mesh networking protocol to connect all your devices.
