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
