MiWi™ Protocol

Low-cost Embedded Wireless Connectivity for Commercial and Smart Home Networks


Developed to enable low-cost, commercial and smart home networks, MiWi is used in applications such HVAC systems and Alarm sensors where reliable sub-GHz connections and long battery life are needed.  MiWi also runs in the 2.4GHz worldwide ISM band.   The MiWi protocol runs on the IEEE 802.15.4 RF Physical Layer.


The MiWi stack offers a significantly smaller foot-print relative to the open standard based ZigBee® compliant protocol stack.  This enables operation in microcontrollers with smaller memory / lower cost.


The main advantages of MiWi Development Environment are:


  • Ease in architecting and deploying wireless networks
  • Ease in portability of the applications across different Microchip RF transceivers
  • Ease in scaling network topologies under the MiWi protocol framework
