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.
Security Settings
Both sides (AP and Station) of the link must have the same security settings.
Device supports various authentication/encryption methods:
 Open – no encryption.
 WEP – 64bit and 128bit key.
 Personal – preshared key encryption with WPA/WPA2 using AES or TKIP.
 Enterprise – RADIUS server based authentication with WPA/WPA2 encryption using AES or
TKIP (requires configured RADIUS server).
By default there is no encryption enabled on the device:
