Hello
When I change LTE_sim_main_launcher_femtocells to ‘omnidirectional_eNodeBs’
meet this error:
Reference to non-existent field ‘network_geometry’.Error in LTE_load_params_dependant (line 450)
switch LTE_config.network_geometryError in LTE_sim_main (line 31)
LTE_config = LTE_load_params_dependant(LTE_config);Error in LTE_sim_main_launcher_femtocells (line 60)
output_results_file = LTE_sim_main(LTE_config);How can i solve it?
Thank You

I suggest that you use the femtocell config file (by leaving the simulation type as ‘tri_sector_plus_femtocells’).
In order to get a hexagonalgrid of macro-BS with omnidirectional antennas, add
LTE_config.antenna.antenna_gain_pattern = ‘omnidirectional’;
in the launcher file or in the femto-confic file.

Thank you for your answer and guidance
(femtocell config file)
in Which sub file is located?
At First Which m.file to start with?17. April 2018 at 8:40 #10279AnneParticipantHi Dr.Martin
I Change simulation type to comment.
you mean that?17. April 2018 at 10:34 #10281Martin MüllerMemberHi Anne:
1. use the launcher file sim_main_launcher_files/LTE_sim_main_launcher_demo_femtocells.m
2. open the associated config file +simulation_config/hex_grid_tilted_with_femtocells.m
3. add the line “LTE_config.antenna.antenna_gain_pattern = ‘omnidirectional’;” to the config file.
This will create a hexagonal grid of macros with omnidirectional antennas and two femto cells per macro BS.
Best regards,

According to what you said
I did three steps above But meet These Errors nevertheless:Reference to non-existent field ‘network_geometry’.
Error in LTE_load_params_dependant (line 450)
switch LTE_config.network_geometryError in LTE_sim_main (line 31)
LTE_config = LTE_load_params_dependant(LTE_config);Error in LTE_sim_main_launcher_demo_femtocells (line 42)
output_results_file = LTE_sim_main(LTE_config);Thanks a lot for your guidance
17. April 2018 at 15:36 #10283Martin MüllerMemberHi Anne,
do you use the default configuration of the launcher and config files?
Please make sure that the simulation type is set to
simulation_type = ‘tri_sector_plus_femtocells’;
as it is in default in the femto launcher file. In the femtocell config file, network geometry is set by default, therefore no error should occur.
Best,

Thank You.
The Previous Error Solved. I Installation Simulator Again and dont change simulation type. And Repeat Three Steps again.
But new problem: The program run the middle true and produce fig1 and fig2 But these Errors occur:Error using dipole (line 88)
Expected a string for the parameter name, instead the input type was ‘double’.Error in
