Hardware
In 2008, Microchip released a 2.4 GHz wireless transceiver module that is compatible with certain Microchip PIC and dsPIC microcontrollers (the Microchip MRF24J40MB), and can be used in production devices. Being ZigBee compliant, and capable of communicating using MiWi wireless protocols, it is based on the IEEE 802.15.4 Wireless PAN standard. Designed only for low-data rates and being low-cost, it has an integrated PCB antenna. The module is regulatory-agency certified for the USA (Federal Communications Commission (FCC)), Canada (Industry Canada) and Europe (ETSI), and would save money for small and medium project designers, by eliminating the need to receive independent FCC certification for their wireless products.
The Microchip ZENA (or formerly, Zigbee Enhanced Network Analyzer) is a wireless packet sniffer and network analyzer following the IEEE 802.15.4 specification on the 2.4 GHz band. The ZENA analyzer supports both the ZigBee and MiWi protocols. Accompanying software can analyze network traffic and graphically display decoded packets. It can also display the network topology and the messages as they flow through the network. With the provided key of the network, data on encrypted MiWi networks can be sniffed and viewed as well.

Famous quotes containing the word hardware:
“A friend of mine spoke of books that are dedicated like this: “To my wife, by whose helpful criticism ...” and so on. He said the dedication should really read: “To my wife. If it had not been for her continual criticism and persistent nagging doubt as to my ability, this book would have appeared in Harper’s instead of The Hardware Age.””
—Brenda Ueland (1891–1985)
