FCC Rules Part 15 Subpart E §15.407(c)
Compliance with FCC requirement 15.407(c)
Data transmission is always initiated by software, which is the passed down through the MAC, through the digital and analog
baseband, and finally to the RF chip. Several special packets are initiated by the MAC. These are the only ways the digital baseband
portion will turn on the RF transmitter, which it then turns off at the end of the packet. Therefore, the transmitter will be on only
while one of the aforementioned packets is being transmitted. In other words, this device automatically discontinue transmission in
case of either absence of information to transmit or operational failure.
