Your question is way too broad. It has so little information that there are dozens of ways to do what you want, or hundreds of pre-assembled modules to choose from.
What is it that you are trying to achieve?
What power sources are available for the transmitter and receiver?
What is the maximum range you need to cover?
Do you want to design and build circuits from scratch, or buy modules and wire them together?
