Yes, you can send remote control signals. RC cars do this. Cell phones do this. WiFi computers do this. XBee serial controllers do this. Radio and TV transmission and receivers do this. You have to be a little more specific in what you need.
How heavy can the receiver be?
How long distance do you need to transmit?
How much current draw is allowable for the receiver?
What kind of interference must be taken into account?
What's your budget?
