preamble provides 72-bit Synchronization field to improve WLAN transmission efficiency with less
overhead.
„
Tx Burst : By default, it’s “ Enable ”. To Disable is to deactivate Tx Burst.
With TX burst enabled, AP will send many packets in a burst, without collision detection and RTS/CTS for each packet. TX
Burst have better throughput but cause interference with other APs in channel.
„
Pkt_Aggregate : By default, it's “ Enable ”
Increase efficiency by aggregating multiple packets of application data into a single
transmission frame. In this way, 802.11n networks can send multiple data packets with the fixed
overhead cost of just a single frame.
„
IEEE802.11H (DFS) : By default, it's “ Disable ”. To Enable is to use IEEE802.11H(DFS)
With DFS(Dynamic Frequency Selection) enabled, radio is operating on one of the following
channels, the wireless device uses DFS to monitor the operating frequency and switch to another
frequency or reduce power as necessary:
DFS Channels 52, 56, 60, 64, 100, 104, 108, 112, 116, 120, 124, 128, 136, 140
The maximum legal transmit power is greater for some 5 GHz channels than for others. When the wireless
device randomly selects a 5 GHz channel on which power is restricted, the wireless device automatically reduces
transmit power to comply with power limits for that channel in that regulatory domain.
The Channel 52-140 is DFS channel. If tuen on IEEE802.11H, AP Will have 60 sec to do channel available
check, and will not send beacon and can not be connect. When OW-200N2 detect radar(5GHz) signal, the AP
will switch channel and stop beacon trasmit between
15 sec.
„
WMM : By default, it's “ Disable ”. To Enable is to use WMM and the WMM parameters should appears.
