Wireless Speed Control via Matlab GUI

Need Help,

I’m doing a project involving wireless speed control for induction motors. The method for varying the speed is via PWM and phase control.
No problem in the output side but the problem is how am i gonna make my system wireless using one arduino ATMEGA644, one USB to UART
adaptor, and 2 RF radios model JZ863. Given the Guided Used Interface in matlab, I can make virtual buttons to control the speed but how will
I send input signals from my PC to my arduino and make my arduino do PWM? RF radios have 5 pins with the last as a sleep control pin but I am
really not familiar in using this?? anybody who can help?? Attached here is the block diagram of what I want to do… Thanks.
