Professional two-way radios operate on radio frequencies that are regulated by the Federal Communications Commission (FCC). To transmit on these frequencies, you are asked to have a license issued by the FCC. This license is not required to purchase the radios but allows the FCC to keep track of how many users are using the frequency and what they are using it for. Most two-way radio users in businesses are required by the FCC to use licensed frequencies. Note that CavCom‘s TeamTalk™ line of hands-free communication devices do not require an FCC license.
