Wireless Earphone

  1. Feb 12, 2008 #1
    Hello Guys

    I am about to plan for building a wireless earphone that uses a transmitter and receiver. I have talked to my professor in regard of it, I figured out that I need a permission to be able to build such a project. Then, I changed some basics that I thought the project would have. Now, I am trying to fix the frequency for both the transmitter and receiver beasue I cannot use big frequencies becasue of the license. My question, How can I fix the frequency for both those circuits ?? and what would you advise me in regard of the schmatics, chips, and circuitry that will be used ?
