===== WLAN =====

The goal is to aquire a part of a WLAN-signal and to decode the most important
bits.


==== Hardware-setup ====

For this test, take a wireless access point and set it to channel 6 at a center
frequency of 2437MHz. This takes care of
EPFLs network that is tuned to channel 1 and 12 at 2412MHz and 2467MHz. The
bandwith of the signal is 22MHz.

The setup can be seen in fig. <ref>cap:WLAN-setup</ref>.

==== Software-setup ====

If you used the GPS beforehand, you have to re-program the FPGA first. For this,
refer to <ref>sec:FPGA</ref>. Once this is done,
you can start the aquisition:

<code>
cd \$SRADIO/Test/WLAN
make rf_tail
../../Tools/Dbg/dbg 2 0 > ../../Matlab/WLAN/wlan_capture.dat
</code>

Then you can use the programs in //\$SRADIO/Matlab/WLAN// to decode the
received WLAN-signal.
