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

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>.

WLAN-setup (wlan_setup.ps)

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:

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

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