Microwave communication is commonly used as a backbone transmission system in wireless communication networks. As a wireless network engineer, you are often required to perform link budget calculations for such Microwave links. One such link is shown below in Figure 1 which operates in the 12 GHz radio frequency band. This link provides 4 Mbps transmission capacity at both transmitter and receiver sides. Furthermore, the system deploys a passive repeater. Following table shows numerical values for this transmission system.
