RX Application
Usage
The
Rx
performance
is
analyzed
by
the
sensitivities
at
different
data
rates.
In
general,
the
sensitivity
is
observed
as
10%
Packet Error
Ratio
(PER)
point
in
11a
and
11g,
and
8%
PER
point in
11b.
PER:
Packet
Error
Ratio
(PER)
is
calculated
by
measuring the
number
of
packets
received
correctly and
comparing
with
the
number of
packets
expected.
%Packet
error rate
=
100*(1-
((Received
packets/expected
packets))
For
carrying
out the receive
test,
connect
the
EVB
to
a
Vector
Signal
Generator
(VSG).
Then
set the
RF
amplitude,
signal
waveform
and the
channel
in
the
signal
generator
before starting the
receive
tests.
You
need
to
configure
the
channel
(as
mentioned
below)
in
the
EVB
with
the
same
channel
which
is
set
in
Signal
Generator.
This
application
can
be
started
in
the
following
steps:
plugged RJ45 cable
into the device and labtop, set the labtop’s ip and the ip of device in
the same network segment,and then Login to the device, send the command via cmd
window.
#
cd /etc/wifi
#
sh ./bcmdhd_active.sh
Then we can start Rx test, test command as blow :
