FireFly WSN Platform

The main Firefly board uses an Atmel ATmega1281 8-bit micro-controller with 8KB of RAM and 128KB of ROM along with Chipcon’s CC2420 IEEE 802.15.4 standard-compliant radio transceiver for communication. The maximum packet size supported by 802.15.4 is 128 bytes and the maximum raw data rate is 250Kbps.

FireFly WSN Platform

FireFly Power Monitoring and Control Board  - In this project, we design and implement a remote switch control and power measurement system by using CMU Firefly wireless sensor board. The basic function for the system is that one central node can remotely switch on or off electronic devices and get the information, e.g. power, back from the switches. The basic design includes three parts: switch module, power measurement module and CMU Firefly board.

FireFly Power Monitoring and Control Board

The demonstration shows that central node can wirelessly control the four lamps individually and the accurate power from each of the node is transmitted back instantaneously. The functions such as power-save and autoswitch pattern are also implemented. The power measurement ranges from 10W to 1000W, which is suitable for most industrial electrical system.

Real-time 4x4 MIMO-OFDM Testbed

Peter Jan L├╝thi from  Switzerland has to his credit this Ph.D. Thesis - VLSI Circuits for MIMO Preprocessing.This is related to design, implementation and demonstration of suitable algorithms for MIMO wireless communication.

Real-time 4x4 MIMO-OFDM Testbed

"The latest mobile applications and the growing number of wireless users are increasing the demand for high-throughput wireless access solutions. Multiple-input multiple-output (MIMO) technology combined with orthogonal frequency-division multiplexing (OFDM) constitute today's most promising approach to exploit the limited radio frequency resources in a highly efficient way.
