IEEE 802.15.4 Low-Rate Wireless Personal Area Network (WPAN)
|
|
============================================================
|
|
|
|
|
|
IEEE 802.15.4 defines physical layers and a media access control for
|
|
wireless networks. ZigBee and 6loWPAN are based on IEEE 802.15.4.
|
|
|
|
This project aims to add experimental WPAN functionality to the Ben
|
|
NanoNote, in order to permit evaluation of overall network performance
|
|
and to examine possible integration into future devices.

Hardware architecture
|
|
---------------------
|
|
|
|
IEEE 802.15.4 transceiver chips are available from several manufacturers,
|
|
including Atmel, Freescale, and Texas Instruments. These chips are similar
|
|
in size, functionality, and cost. The first prototype is based on the
|
|
Atmel AT86RF230.
|
|
|
|
The RF module will be physically placed on the left side of the LCD
|
|
module, replacing part of the display's PCB.
|
|
|
|
When installed in the Ben, the transceiver will connect directly via SPI
|
|
to the Jz4720. For development, a SiLabs C8051F326 microcontroller
|
|
implements a USB to SPI conversion.
