calculation for maximum power (25.39-0.39db cable loss + 11dbi = 36dbm)
is 0.792009 mW/cm

for a minimum separation distance of 20cm.
Data transmission is always initiated by software, which is then 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 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 discontinues transmission in case of either absence of information to transmit or operational failure.
