Question

A link budget is accounting of all __________

(a) Gain and losses from the transmitter

(b) Power transmitted by transmitter

(c) Power received by receiver

(d) Power transmitted and received

I had been asked this question in an internship interview.

My question is taken from Practical Link Budget Design Using Path Loss Models topic in division Mobile Radio Propagation: Large – Scale Path Loss of Wireless/Mobile

Answer 1

Right answer is (a) Gain and losses from the transmitter

The best I can explain: A link budget is accounting of all of the gains and losses from the transmitter, through the medium (free space, cable, waveguide, etc.) to the receiver in a telecommunication system. It accounts for the attenuation of the transmitted signal due to propagation, as well as the antenna gains and miscellaneous losses.
