HexGrid generates a grid of N Hexgons centred at `center` of size hexsize, returns an array of 3D locations of the centres of the hexgonals, This centers can be used to place the base-stations for Multi-cell simulations.

% In the code, I will create a hexagon centered at (0,0) with radius R.

HexRandPoints generates N points uniformly distributed inside a hexagon of radius hexRadiuscentre complex128, hexRadius float64, Npoints int, rdegree float64 based on DOI: 10.1109/CAMAD.2009.5161465.

% This will create a hexagon centered at (0,0) with radius R.

Simplest point for origin centred, rectangular region of length size.

Default carrier frequency.
