Compliance with FCC requirement 15.407(c)
Data transmission is always initiated by software, which is the passed down through the MAC,
through the digitaland 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.
Frequency Tolerance: ±20ppm
