Client isolation
– select to enable the layer 2 isolation that blocks clients from communicating with
each other. Client isolations is available only in Access Point (auto WDS) mode.
Enable DFS
– select to enable radar detection. With enabled DFS, APC unit monitors the operating
frequency for radar signals. If radar signals are detected on the channel, the APC unit randomly
selects a different channel.
Enable AMSDU
– enable the AMSDU packet aggregation. If enabled, the maximum size of the
802.11 MAC frames will be increased.
Mode
– choose the AP antenna operating mode:
 SISO – single input single output. The device will use only one antenna for data transfer. The
antenna will be chosen automatically.
 MIMO – multiple input multiple outputs. The device will use two antennas for data transfer (two
Simultaneous streams).
Max data rate
– choose the maximum data rate in Mbps at which should transmit packets. The APC
Will attempts to transmit data at the highest data rate set. If there will be an interference encountered,
The APC will step down to the highest rate that allows data transmission.
Max data rate N
– choose the data rates in Mbps at which should transmit packets for the selected
802.11n mode. The APC will attempts to transmit data at the highest data rate set. If there will be an
interference encountered, the APC will step down to the highest rate that allows data transmission.
Disable data rate fallback
– when this option is selected, the constant Max data rate will be set
without a step back to the next highest data rate for APC data transmission.
Short GI
– enable short guard interval. If selected, then 400ns value will be used, else 800ns.
MPDU density
– define minimum time between PPDU‟s.
ACK timeout
– specify the ACK timeout using slider or enter the value manually. Ack timeout can be
entered by defining the link distance or specifying time value. Too low value of the ACK timeout will
give very low throughput. A high value may slow down the link in noisy environment. A low value is far
worse than a value slightly too high. ACK Timeout value should be tuned to the optimal value for the
maximum link throughput.
7.2.6 Wireless Mode: Station
Station WDS has the same wireless settings.
The Station wireless settings a bit differ from the Access Point’s settings: there is possibility to scan
SSID of the surrounding APs and choose the required one.
Use W ireless Settings to setup radio interface of the device.
Basic Wireless Settings
SSID
– specify the SSID of the wireless network device.
Scan
– click this button to scan for surrounding wireless networks. Found network SSID‟s will be
Available in drop down menu.
IEEE mode
– specify the wireless network mode.
Channel width - The default channel bandwidth for 802.11 radio is 20MHz. The 802.11n allow
channel bonding in such way the total channel width becomes 40MHz.
