Waspmote may have two radios at the same time connected when using the Expansion Radio Board allowing the creation of bridges among different networks such as ZigBee and Wifi, Wifi and 3G/GPRS, RFID and Bluetooth, etc.

Open source Wireless sensor platform - Waspmote

"The idea behind the Raspberry Pi to Arduino shields connection bridge is to allow to use any of the shields, boards and modules designed for Arduino in Raspberry Pi. It includes also the possibility of connecting digital and analog sensors, using the same pinout of Arduino but with the power and capabilities of Raspberry."



Cooking Hacks - Tasty Electronics for the Arduino and Raspberry Pi Community.

The have a wide range of electronic products and kits including Arduino, ZigBee, GPRS, Sensors, Servos, Leds, LCDs etc.

Peter Jan Lüthi 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. "
