Assertion(A)–Although 5G wireless service will provide fast internet speed than 4G but 5G signal towers will waste more energy and power than that of 4G Reason (R)–5G signal will be composed of highly directional and non-interfering electromagnetic waves

A and R are individually true and R is the correct explanation of A.

Explanation:

High frequencies of wireless spectrum (from almost 30 GHz to 300 GHz) which will be used in 5G services, are composed of highly directional, non-interfering waves and thus can be used right next to
other wireless signals without causing interference. This is very different from 4G towers that fire data in all directions, potentially wasting both energy and power to beam radio waves at locations that are not even requesting access to the internet. Hence, 4G signal towers waste more energy thanthat of 5G. Hence, Assertion is false but Reason is true.
