By default there is no encryption enabled on the device:
Figure 39 – iPoll Security: Open
Personal WPA/WPA2 encryption must be specified with the pre-shared key:
Figure 40 – iPoll Security: Private WPA/WPA2 Encryption
Passphrase – specify the WPA or WPA2 passphrase [8-63 characters]. The passphrase will be
converted to key format, selected above.
AdvancedWirelessSettings
Advanced wireless settings allow configuring the iPoll AP to get the best performance/capacity of the
link:
Figure 41 – iPoll Access Point: Advanced Wireless Settings
Transmit power – set the unit’s transmitting power at which the device will transmit data. The larger
the distance, the higher transmit power is required. To set transmit power level use the slider or enter
the value manually. When entering the transmit power value manually, the slider position will change
according to the entered value. The maximum transmit power level is limited to the allowed value by
country in which device is operating regulatory agency.
Enable ATPC – select to enable Automatic Transmit Power Control (ATPC). If enabled, device radio
will
continuously communicate with remote unit’s radio in order to adjust the optimal transmit power
automatically.
Enable DFS – select to enable a radar detection. With enabled DFS, iPoll AP monitors the operating
frequency for radar signals. If radar signals are detected on the channel, the unit randomly selects a
different channel. Note that if APC is operating on channel where DFS is required, this option
automatically will be enabled.
Mode – choose the unit’s 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 output. The device will use two antennas for data transfer
(two simultaneous streams).
Max data rate – select the device data transmission rates in Mbps from the drop-down list. The iPoll
AP will attempt 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.
Transmit queue length, frames – specify the length in frames of the transmit queue.
