Fragmentation – specify the Fragmentation threshold using slider or enter the value manually [256-
2346 bytes]. This is the maximum size for a packet before data is fragmented into multiple packets.
Setting the Fragmentation threshold too low may result in poor network performance. Only minor
modifications of this value are recommended.
RTS – specify the RTS threshold using slider or enter the value manually [0-2347 bytes]. The RTS
threshold determines the packet size of a transmission and, through the use of an access point, helps
control traffic flow.
Quality of service (WMM) – enable to support quality of service for traffic prioritizing.
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. Note that if APC is operating on channel where DFS is required, this
option automatically will be enabled.
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 output. 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.
BA window size – specify BA (Block ACK) window size [1-64].
WirelessMode:iPollAccessPoint
The iPoll wireless mode is designed for point to multipoint wireless solutions. The iPoll Access Point
establishes a connection only with iPoll Stations thus creating a reliable network
