What must be done before using a new digital protocol on the air?
Type-certify equipment to FCC standards
Obtain an experimental license from the FCC
Publicly document the technical characteristics of the protocol✓پاسخ درست
Submit a rule-making proposal to the FCC describing the codes and methods of the technique
توضیح
The rules do not require permission to invent a digital mode; they require that others be able to understand what you are transmitting. Publishing the technical characteristics is what keeps a new protocol from being encoding that obscures meaning.
