MiWi™ Protocol

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

Developed to enable low-cost, commercial and smart home networks, the MiWi™ protocol is used in applications such HVAC systems and alarm sensors where reliable self-healing mesh networking is needed. The MiWi protocol supports operation in the IEEE 802.15.4 radio PHY in the sub-GHz and 2.4 GHz ISM bands.

The MiWi protocol stack offers a significantly smaller footprint relative to the open standard-based Zigbee® compliant protocol stack. This enables operation in microcontrollers with smaller memory/lower cost. A typical end node requires only 20 KB of code space.

Our MiWi Mesh Stack is available for Microchip Studio, the Integrated Development Platform (IDP) for developing and debugging all AVR® and SAM microcontroller applications. Microchip Studio gives you a seamless and easy-to-use environment to write, build and debug your applications written in C/C++ or assembly code. The MiWi Mesh code is part of the Advanced Software Framework (ASF). Here are some links to other helpful resources:
