Table 1: ITU-R M.2135-1 Path Loss model
Note 1:
Breakpoint distance dBP'=4hBS'hMS'fc/c, where fc is the centre frequency in Hz, c=3×108 m/s is the propagation velocity in free space, and hBS' and hMS' are the effective antenna heights at the BS and the MS, respectively. The effective antenna heights hBS' and hMS' are computed as follows: hBS'=hBS-hE, hMS'=hMS-hE, where hBS and hMS are the actual antenna heights, and hE is the effective environment height assumed to be hE=1 m.
...
hBS=maxhTx, hRx
hMS=minhTx, hRx
