Federal Communication Commission Interference Statement
This equipment has been tested and found to comply with the limits for a Class B digital device,
pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable
protection against harmful interference in a residential installation. This equipment generates
uses and can radiate radio frequency energy and, if not installed and used in accordance with
the instructions, may cause harmful interference to radio communications. However, there is no
guarantee that interference will not occur in a particular installation. If this equipment does
cause harmful interference to radio or television reception, which can be determined by turning
the equipment off and on, the user is encouraged to try to correct the interference by one of the
following measures:

cause harmful interference to radio or television reception, which can be determined by turning
the equipment off and on, the user is encouraged to try to correct the interference by one of the
following measures:
x Reorient or relocate the receiving antenna.
x Increase the separation between the equipment and the receiver.
x Connect the equipment into an outlet on a circuit different from that to which the
receiver is connected.
x Consult the dealer or an experienced radio/TV technician for help.
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two
conditions: (1) This device may not cause harmful interference, and (2) this device must accept
any interference received, including interference that may cause undesired operation.
conditions: (1) This device may not cause harmful interference, and (2) this device must accept
any interference received, including interference that may cause undesired operation.
UNII devices operating within 5.15-5.25 GHz are to be restricted to indoor operations to reduce
any potential for harmful interference to co-channel MSS operations.
any potential for harmful interference to co-channel MSS operations.
FCC 15.407(c) states: The device shall automatically discontinue transmission in case of either
absence of information to transmit or operational failure. These provisions are not intended to
preclude transmission of control or signaling information or the use of repetitive codes used by
certain digital technologies to complete frame or burst intervals. Applicants shall include in their
application for equipment authorization a description of how this requirement is met.

Description to meet FCC 15.407(c):
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.
