# Be sure to copy and replicate for the number of UEs and BSs desired.

# Other values will be added to define parameters such as antenna beamwidths, front to back ratio, etc.
# If not specified, defaults will be used [67 deg azimuth beamwidth, 7.5 deg elevation beamdwidth, -30dB FBR]
# and can be changed in the MATLAB init_sim script.
