Figure 15 – Channel List Table
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.
Channel table – select the channel(s) at which the Access Point will operate. If more than one
channel is selected, then autochannel feature will be enabled. Automatic channel selection allows AP
to select a channel which is not used by any other wireless device or, if there are no free channels
available - to select a channel which is least occupied. The table displays detailed information about
each channel: TX limit, EIRP limit and APTC required.
AdvancedRadioSettings
Advanced parameters allow configuring the device to get the best performance/capacity of the link.
Max 802.11n MCS index – choose the maximum rates to specify the modulation and coding scheme
(MCS) rates at which data can be transmitted between the access point and the client. If there will be
an interference encountered, the APC will step down to the highest rate that allows data transmission.
Max legacy data rate – choose the maximum data rate in Mbps at which AP should transmit packets.
The 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.
AMSDU – enable the AMSDU packet aggregation. If enabled, the maximum size of the 802.11 MAC
frames will be increased.
Short GI – enable short guard interval. If selected, then 400ns value will be used, else 800ns.
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/CTS – 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.
