    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_geometry

    Error 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
    Best Regards

    Hi Anne,

    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.

    Best,
    Martin

    Hi
    Thank you for your answer and guidance
    (femtocell config file)
    in Which sub file is located?
    At First Which m.file to start with?

    Hi Dr.Martin
    I Change simulation type to comment.
    you mean that?

    Hi 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,
    Martin

    Hi Dr.Martin
    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_geometry

    Error 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

    Hi 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,
    Martin

    Hi Dr.Martin
    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’.
