6 TP/SNR
This view has a single chart, which displays the relationship between the measured throughput
speed and the signal to noise ratio of a given access point. Measurements usually take into
account only the theoretical maximum throughput speed. Since the measurements vary by
network and hardware, the view instructs the user to modify the parameters. Modify the
parameters directly in the view.
The picture below is an example on how to interpret the TP /SNR chart.
The theoretical TP/SNR curve
indicates the best data
throughput speed for a given
SNR value.
A large variation in throughput rate
when the SNR value is good indicates
possible performance issues in a
wired network or a severely loaded
radio.
The SNR variation indicates radio
frequency interference or constant
changes in radio environment.
The maximum speed of an
end-to-end connection.
