3. Overview
3.1.
Scope
This document describes the specifications of US302 WLAN USB
module. The low power consumption and smaller size are suitable for USB
adapter.
US302 implements half-duplex OFDM, CCK, and DSSS baseband
processing supporting all IEEE 802.11n data rates. The MAC supports the
IEEE 802.11 wireless MAC protocol as well as 802.11i security, receive
and transmit filtering, error recovery, and quality of service(QoS), and
Extended Range technology, dramatically increasing WLAN performance

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/RSS-210 of the FCC/IC 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:
Reorient or relocate the receiving antenna.
Increase the separation between the equipment and receiver.
Connect the equipment into an outlet on a circuit different from that to which the
receiver is connected.
Consult the dealer or an experienced radio/TV technician for help.
FCC/IC Caution: Any changes or modifications not expressly approved by the party
responsible for compliance could void the user's authority to operate this equipment.
This device complies with Part 15/RSS-210 of the FCC/IC 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.
Radiation Exposure Statement:
This equipment complies with FCC/IC radiation exposure limits set forth for an
uncontrolled environment. This equipment should be installed and operated with
minimum distance 20cm between the radiator & your body. This transmitter must not
be co-located or operating in conjunction with any other antenna or transmitter.
This device is intended only for OEM integrators under the following conditions:
1. The antenna must be installed such that 20 cm is maintained between the
antenna and users, and
2. The transmitter module may not be co-located with any other transmitter or
antenna,
IMPORTANT NOTE: In the event that these conditions can not be met (for example
certain laptop configurations or co-location with another transmitter), then the FCC/IC
authorization is no longer considered valid and the FCC/IC ID can not be used on the final
product. In these circumstances, the OEM integrator will be responsible for re-evaluating
the end product (including the transmitter) and obtaining a separate FCC/IC authorization.
