You are designing a microwave link to enhance a wireless LAN (local area network) system's coverage. This particular LAN uses millimeter-wave channels in the 35-GHz range. Suppose the transmitter can supply up to P,= 10 mW, and the receiver requires P = 35 nW to operate satisfactorily. (a) If both transmitter and receiver antennas are isotropic (G₁ = G₁ = 1), what is the maximum free-space range R, that the system can cover? (b) Assuming you can use identical antennas at both transmitter and receiver with gain GR = G,= G, what gain is required to increase the range to R₂ = 200 m? Express G both in terms of a numeric ratio (G) and a power ratio in dB (GB). You are designing a microwave link to enhance a wireless LAN (local area network) system's coverage.
