Mica-Z
The SWIS group currently has 60 Mica-Z nodes and 30 sensor boards (distributed by Crossbow Technology, Inc.). They are each equipped with an Atmel Atmega 128L processor and a Chipcon CC2420 radio transmitting in the 2.4GHz ISM band. Using TinyOS, they send and receive packets conforming to a subset of the ZigBee standard, and are interoperable with the custom radio extension turrets we have built for the Alice and the e-puck.
