Protocols
Microchip has released two application notes which present technical information on MiWi. These are not primarily protocol specifications and more than half of these documents are focused on implementing the MiWi protocol on Microchip microcontrollers.
As of 2009, interoperable third party implementations have not appeared. Unless they do, it will not be clear if those specifications are complete or accurate enough to serve roles other than supporting Microchip's code or being one more proprietary example of a lightweight WPAN stack. Many developers trying to use WPAN technologies have observed that Zigbee seems undesirably complex. Accordingly, there exists a technical niche for a simpler protocols, of which MiWi is a proprietary example.
