  Microwave Transmission: 30 Technical Interview Questions and Answers What is the difference between TDM and Ethernet in microwave communication? Ans: TDM (Time Division Multiplexing) allocates fixed time slots for data streams, ideal for circuit-switched traffic like voice. Ethernet is packet-based, better for variable data loads and flexible bandwidth usage. What are the key layers in a microwave transmission system? Explain their roles. Ans: Key layers include Physical (signal transmission), Data Link (framing, error detection), and Network (routing). Together, they ensure reliable data delivery across microwave links. What is the difference between Line-of-Sight (LOS) and Non-Line-of-Sight (NLOS) links? Ans: LOS requires a clear direct path between antennas, offering better performance. NLOS uses reflection, diffraction, or scattering to establish connectivity in obstructed environments. How does Adaptive Modulation work in microwave radios? Ans: Adaptive Modulation dynami...
