Industry Canada Statement
Operation is subject to the following two conditions: (1) this device may not cause interference,
and (2) this device must accept any interference, including interference that may cause
undesired operation of the device.
and (2) this device must accept any interference, including interference that may cause
undesired operation of the device.
To reduce potential radio interference to other users, the antenna type and its gain should be
so chosen that the equivalent isotropically radiated power (e.i.r.p.) is not more than that
permitted for successful communication.

IC RSS-247 A9.4 (4) states: The device shall automatically discontinue transmission in case of
absence of information to transmit, or operational failure. A description of how this is done shall
accompany the application for equipment certification. Note that this is not intended to prohibit
transmission of control or signaling information or the use of repetitive codes where required by
the technology.

Description to meet IC RSS-247 A9.4(4):
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 transceiver. Several special
packets (ACKs, CTS, PSPoll, etc) 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 are being
transmitted.
