(Eq. 208217)
where:
linear attenuation due to dry air (oxygen) in dB/km
...
- Attenuation due to water :
(Eq. 209218)
for f < 350 GHz
...
f<= 57 GHz (Eq. 210219)
57 < f <= 60 GHz
60 <f <= 63 GHz
for f> 63 GHz
Note: For simplification a linear interpolation between 57 and 63 GHz is used. The maximum is 15 dB/km for 60 GHz.
