    22== Description ==
    3 Collects Wimax radio link parameters with corresponding GPS coordinates and sends to OML server.
     3Collects Wimax radio link parameters with corresponding GPS coordinates on the client and sends to OML server.
    44The following parameters are recorded and sent to the OML server: Center frequency, RSSI, CINR, Transmit power, Time from GPS, Latidute, Longitude, Altitude.
     5The source code is available at [source:/wimax_client/trunk]

    119 Alternatively, OCTAVE or MATLAB can be used to process the data. The Octave script [http://wimax.orbit-lab.org/attachment/wiki/WiMAX/30/02/plot3d.m plot3d.m] was used to plot the RSSI in 3D from the datafile: [http://wimax.orbit-lab.org/attachment/wiki/WiMAX/30/02/exp5_rssi_oct.dat exp5_rssi_oct.dat].
    120 The following is a rudimentary 3D plot of the RSSI in front of Rutgers Winlab.
