Point to Point and Mesh Networking
MiWi™ and MiWi P2P (peer-to-peer)
MiWi™ and MiWi P2P are proprietary protocol stacks developed by Microchip for short-range wireless networking applications based on the IEEE 802.15.4™ wireless personal area network (WPAN) specification. The MiWi protocol stacks are optimized for low-power, low data rate, cost sensitive application and offer a small foot-print alternative to the standard based ZigBee® compliant protocol stack.
Features
- Lowest-cost fully functional network protocol for IEEE 802.15.4 transceivers
- Ultra small memory footprint proprietary protocols
- Simple, low cost solution for customers who do not need interoperability with other ZigBee devices
- No Fees or certification required
- Protocol stacks are provided FREE of charge when used with a Microchip's PIC® microcontrollers and the MRF24J40 transceiver/transceiver module
Description
|
IEEE Std 802.15.4™ is created to address low-cost, low-data rate, and low-power design application for short-range Wireless Personal Area Networks (WPAN). The IEEE 802.15.4 defined standard for wireless connectivity among fixed, portable, and moving devices in a WPAN environment is the foundation for network protocols such as standard based ZigBee® and Microchip’s proprietary MiWi™ and MiWi P2P. |
