User's Guide

USER GUIDE
• Data Rate: Select a data transmission rate from the drop-down menu. The ‘best’
selection will adapt the rate to the best available. Alternately, the user has the option of
selecting a fixed data rate, but if that data rate is unachievable no connection will be
made. The default value is ‘best’. The Wireless Modules will adjust the data rate
automatically based on the noise conditions, distance to the connected user device, etc.
so Strix does not recommend changing this parameter.
• Transmit Power: Select the Wireless Modules’ level of transmit power from the drop-
down list box. The choices are Full, Half (-3dB), Quarter (-6dB), Eighth (-9dB) and
Minimum. Decrease the transmit power if you wish to decrease the range of the
Wireless Modules in the Access/One Network. The default value is ‘Full’. Note: the
Wireless Modules themselves will adapt to the conditions in the RF ‘neighborhood’
automatically, so Strix does not recommend changing this parameter.
• Beacon Interval (20 - 1000ms): Enter a value between 20 and 1000 in milliseconds
that specifies the Beacon Interval. The default value is 100.
• Data Beacon Rate (1 - 16384): Specifies the Data Beacon Rate. Enter a value between
1 and 16384 that specifies the Delivery Traffic Indication Message (DTIM). Increasing
this interval allows the station to sleep for longer periods of time resulting in power
savings in exchange for some degradation in performance. The default value is 1.
• Fragment Length (256 - 2346 bytes): Enter a value between 256 and 2346. This
fragment length setting will determine the frame size of the wireless frame. Wireless
frames will be reassembled by the Access/One Network Wireless Modules before being
forwarded to the Ethernet port, provided the frame is smaller than the Ethernet MTU
(1536 bytes). The default value is 2346.
• RTS/CTS Threshold (256 - 2346 bytes): Enter a value between 256 and 2346 that
specifies the RTS/CTS threshold. The default value is 2346.
• Enable 802.11a Outdoor Auto Channel Scan: Certain countries provide for different
indoor and outdoor frequencies/channels. Depending on the Country Code selected in
the Country Code field, use this checkbox to enable/disable the use of outdoor channel
frequencies. Selecting this checkbox will enable the Auto Channel Scan to search
through the outdoor frequency list. The default value is deselected/disabled.
• Short Preamble: The short preamble improves network efficiency by reducing the
preamble from 128 bits to 56 bits. This is an optional feature within the 802.11b standard
and most 802.11b NICs support short preambles. 802.11g is required to support both
short and long preambles. This does not apply to 802.11a.
