Differences Between 5G and 4G Link Budgets

5G and 4G have no difference on the C-band. However, the body block loss, tree fading, rain attenuation, and snow/ice loss are introduced in 5G.

As seen in the table itself, the differences are not so much due to 4G vs 5G, as to the physical constraints when using mmWave bands, instead of the current LTE bands.
