DESCRIPTION
These show the strength of the signal. The
NWD210N has two internal antennas, each of
which has a separate display bar.
The signal strength depends mainly on the
antenna output power and the distance
between your NWD210N and the AP or peer
computer.
Click this to display the Signal Strength 1 and
2 values in dBm (decibels below 1 milliwatt).
This displays the amount of interference on the
wireless connection.
This section displays advanced information
about the 802.11n wireless connection (if you
are using 802.11b or 802.11g, nothing displays
here).
HT stands for "high throughput".
BW: this displays the bandwidth (20 or 40 Mhz)
of the wireless connection.
GI: this displays the guard interval length. The
guard interval is used to prevent wireless
transmissions from interfering with one another.
MCS: this displays the modulation and coding
scheme, which dictates how the data is
transmitted over the wireless link.
