1 Introduction
The AT86RF231 diversity board demonstrates the capabilities of the 802.15.4
compliant 2.4 GHz radio transceiver AT86RF231. With the high performance
ATmega1281V AVR microcontroller it serves as a full function network node that is
capable of hosting a MAC implementation driven by two AAA batteries for more
than one year. Two ceramic chip antennas increase the link budget in a typical
indoor scenario with multipath fading effects.
