iii
Outdoor operations in the 5.15-5.25GHz band is prohibited.
This device has no Ad-hoc capability or peer-to-peer operations for 5250~5350
and 5470~5725 MHz.
IEEE 802.11b or 802.11g operation of this product in the U.S.A. is firmware-limited
to channels 1 through 11.
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 authorization is no longer considered valid and the FCC 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 authorization.
Note: This device has the same WLAN behavior with all other WLAN devices
because we design this device to be compliant to 802.11 specifications.
The fundamental access method of the IEEE802.11 MAC is CSMA/CA, that
means when one station desiring to transmit sense the medium, if the medium is
busy(i.e. some other station is transmitting) then the station will defer its
transmission to a later time. If the medium is sensed free then the station is
allowed to transmit. The receiving station will check the CRC of the received
packet and send an acknowledgement packet(ACK). Receipt of the ACK will
indicate that no collision occurred. If the sender does not receive the ACK then
it will retransmit the fragment until it gets acknowledged or thrown away after
a given number of retransmissions
When WLAN device is in idle status, it is listening (RX), and it won’t send any
packets.
In fault condition, or WLAN device is out of control, WLAN device self can not
generate any packets, even beacon frames, so that WLAN device won’t send
out unexpected frames to air and break FCC rules.
