MiWi is a proprietary wireless protocol supporting peer-to-peer, star network connectivity. It was designed by Microchip Technology. MiWi uses small, low-power digital radios based on the IEEE 802.15.4 standard, and is designed for low-power, cost-constrained networks, such as industrial monitoring and control, home and building automation, remote control, wireless sensors, lighting control, and automated meter reading.[1]
The MiWi protocol is supported on Microchip's SAMR30 (sub-gigahertz)[2] and SAMR21 (2.4 GHz)[3] ARM Cortex-M0+ devices and modules. Legacy MiWi protocol code supporting PIC and dsPIC microcontrollers has been frozen and is no longer recommended for new designs; however, it is still available in the Microchip Library for Applications (MLA)[4] for the MPLAB Integrated Development Environment.[5]
