60 NTU Optical Network Terminals
– 802.11n Protection—when enabled, enhances the security, but decreases the bandwidth;
– Support 802.11n Client Only – when enabled, denies 802.11b/g clients to access the device;
– RIFS Advertisement—Reduced Interframe Space, reduces the interval between data units (PDUs),
increases Wi-Fi efficiency;
– RX Chain Power Save – disables one of the device's antennas to save energy;
– RX Chain Power Save Quiet Time—time period when the traffic intensity should be less than the PPS
value to activate the power saving function;
– RX Chain Power Save PPS—upper limit of the PPS parameter (packet per second). If the packets intensity
of the WLAN interface does not exceed this value during the time specified in RX Chain Power Save Quiet
Time, the power saving mode is activated.
– 54g™ Rate—set the transfer rate in 54g™ compatibility mode;
– Multicast Rate—set the transfer rate for multicast traffic;
– Basic Rate—basic transfer rate;
– Fragmentation Threshold—set the fragmentation threshold, in bytes. If a packet size exceeds the value,
the packet is fragmented into parts of the corresponding size;
– RTS Threshold—if the packet is smaller than the RTS threshold value, the RTS/CTS mechanism (with
request to send/clear to send packets) is not used;
– DTIM Interval—time period after which the broadcast and multicast packets in the buffer will be
delivered to wireless clients;
– Beacon Interval—time period for transmission of informational packets, which indicate activity of the
access point, to the wireless network;
– Global Max Clients—maximum possible number of wireless clients;
– XPress™ Technology—provides an increase in throughput in 802.11g networks up to 27 %. XPress™
Technology can increase the throughput up to 75 % in mixed networks (802.11g and 802.11b).
– Transmit Power—define the signal power of the access point;
– Transmit Power Boost —high signal power of the access point; It is not recommended to use.
– WMM (Wi-Fi Multimedia)—enables the Wi-Fi Multimedia (WMM) mode. The mode allows the fast and
high-quality transmission of audio and video content simultaneously with data transmission;
– WMM No Acknowledgement—when this mode is used, the receiving side does not acknowledge the
received packets. This increases transmission efficiency of low-interference medium, however decreases
the efficiency of high-interference one;
– WMM APSD—set automatic transition into the power saving mode (if enabled, automatic transition is
allowed);
– Enable Traffic Scheduler – use client indicators to balance broadcast usage by directions;
– Airtime Fairness (ATF) – function for reducing the negative impact of a slow devices to bandwidth of a
wireless network.
