| 3 | Collects Wimax radio link parameters with corresponding GPS coordinates on the client and sends to OML server. |
4 | 4 | The following parameters are recorded and sent to the OML server: Center frequency, RSSI, CINR, Transmit power, Time from GPS, Latidute, Longitude, Altitude. |

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]. |
