TDM Coordination
Stands for “Time-Division Multiplexing” technique; this resource reservation control mechanism
can avoid packet collisions and send the packets much more efficiently allowing for higher
effective throughput rates. This function is only available in CSMA BS and CPE mode. Enable
this function on both BS and CPE devices. It is highly recommended to enable TDM
coordination when there are multiple CPEs needing to connect to the BS in your application.
NoACK
Under TDMA mode, enabling NoACK can enhance throughput, but it might result in higher error
rates in a noisy environment.
WMM
WMM (Wi-Fi Multimedia) is a subset of 802.11e. It allows wireless communication to define a
priority limit on the basis of data type, thus time-sensitive data, like video/audio data, may have a
higher priority than a common data type. To enable WMM, the wireless client should also
support it.
Super Mode
Super mode is an effective way to enhance performance. It can boost the transmission data rate
up to 108Mbps. The SGT-LD-5-23 provides you with three kinds of Super mode, which are Fast
Frame, Burst and Compression. To enable Super Mode, the remote SGT-LD-5-23 should also
have this function enabled. For more information you may refer to Super Mode in Chapter 4
Advanced Settings.
