Post processing of Experiment logs

Ericsson 5G experiments are still under development and not yet generally available.

Sample Experiment on Ericsson 5G network

• Experiment site: Lake Wheeler Field Lab (LWFL)
• Network: Ericsson 5G NSA network
• Portable Node: SPN1 with Quectel model
• UAV : SAM
• Plan file: MidpinesLIne_W_NW_SW_5mps_1278m.plan (UAV flying at 30 m altitude , 5 m/s speed in a zig-zag path)
• Description: The goal of the experiment is to collect radio parameters, for example RSRP, RSRQ, SINR etc., at the SPN1 which is carried by the UAV and flown along the flight path defined by the plan file. In addition, the experiment can also be used to characterize some of the performance KPIs like throughput and delay.

Radio log post-processing#

• Radio log file : At the end of the experiment, the following radio log files are available for post-processing.

Serving_cell_Params_ENDC.csv#

Neighbourcell_Params_intra_.csv#

Basic_and_Other_Params.csv#

• Copy the following Matlab files for Radio post processing from Matlab _Radio_log_postprocessing folder to your working directory

main.m#

process_txt_CS.m#

process_csv_GPS_matlab.m#

doubletime2str.m#

plot_error_vs_threshold.m#

RF measurements post-processing#

For post-processing the Serving cell RF parameters#

• Copy the Serving_cell_Params log file to the working folder
• Similarly, copy the vehicle log file as vehicleOut.txt to the working folder
• Set the parameter "proc" in the main.m matlab file as proc = "RF"
• Run the main.m file in Matlab
• The matlab model will create various plots and input.csv file for Google earth or map plotting

PHY layer measurements post-processing#

To post-process Serving cell PHY parameters#

• Copy the Basic_and_Other_Params log file as phy_log.txt to the working folder
• Set the parameter "proc" in the main.m matlab file as proc = "PHY"
• Similarly, copy the vehicle log file as vehicleOut.txt to the working folder
• Run the main.m file in Matlab in the working folder.
• The matlab model will create various plots and input.csv file for Google earth or map plotting

Ping Traffic log post-processing#

• Ping traffic log file : The traffic script creates the following ping log file:

Ping_log_yyy_mm_dd_hh_mm_ss.log.txt

• Copy the following Matlab files for Ping traffic post processing from Matlab _Traffic_Ping_log_postprocessing folder to your working directory

main.m#

process_txt_ping.m#

process_csv_GPS_matlab.m#

• Copy the ping log file as ping_log.txt to the working folder
• Similarly copy the vehicle log file as vehicleOut.txt to the working folder
• Run the main.m file in Matlab in the working folder.
• The matlab model will create various plots and input.csv file for Google earth or map plotting
