Data transmission is always initiated by software, which is then pass down through

the MAC, through the digital and analog baseband, and finally to the RF chip. Several

special packets (ACKs, CTS, PSPoll, etc…) are initiated by the MAC. There 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 are being transmitted.
