Viewing System Information

The Information Screens provide information about the MM2211 Gateway settings.

System Information

The System Information screen is the first screen to appear once you login to the MM2211 Gateway. Figure

21 shows the System Information window.

Transmit Power Select the desired Adapter transmit power from the drop-down menu. We

recommend that you use the default power, Full.

The options are:

•Full

• Half (-3 dB)

• Quarter (-6 dB)

• Eighth (-9 dB)

• Minimum

The default is Full.

Fragment Length The fragment length. The range is between 256 and 2346 bytes. The

default is 2346.

The MM2211 Gateway uses fragmentation to divide 802.11 frames into

smaller fragments which are sent separately to the destination. Only

unicast frames can be fragmented. The fragment length can be between

256-2346 bytes. If the data that the MM2211 Gateway is transmitting is

larger than the threshold, it will trigger the fragmentation function. If the

packet size is equal to or less than the threshold, the gateway will not use

fragmentation. In a good wireless environment, the larger the fragment,

the more efficient the network operates. In a noisy environment, the

fragment length should be adjusted to a smaller size to minimize

retransmission and increase the reliability of the transmission.

RTS/CTS Threshold The RTS-CTS threshold range. The range is between 256 and 2346. The

default is 2346.

The RTS-CTS threshold is a value that determines at what frame length

the request-to-send/clear-to-send (RTS-CTS) function is triggered. By

default, this threshold is set at its highest value. A lower threshold value

means that the RTS-CTS function is triggered for smaller frame lengths.

A lower threshold may be necessary in environments with excessive

signal noise or hidden nodes; but this may result in some performance

degradation.
