Expected Interview Questions
What is the difference between analog and digital modulation?
Analog modulation varies a continuous carrier property such as amplitude or frequency with the message signal, while digital modulation maps discrete symbols onto carrier parameters, offering better noise resilience and enabling error correction and data compression.
Explain the concept of signal-to-noise ratio.
Signal-to-noise ratio compares the power of a desired signal to the power of background noise. A higher ratio indicates a clearer signal and generally supports higher data rates and more reliable communication.
How does a cellular network handle handover?
A handover transfers an active connection from one base station to another as a user moves. The network monitors signal quality, coordinates between cells, and switches the link seamlessly to maintain continuity.
What are the key challenges of 5G deployment?
Key challenges include densifying infrastructure, managing spectrum availability, controlling interference, ensuring security, and delivering reliable coverage in urban and rural areas at reasonable cost.
Describe how you would troubleshoot poor network coverage.
I would gather performance data, identify coverage gaps, check antenna orientation and power settings, analyze interference sources, and run field tests before recommending configuration changes or additional infrastructure.
What is MIMO technology?
MIMO uses multiple antennas at the transmitter and receiver to improve capacity and reliability. It exploits spatial multiplexing and diversity to send more data and combat fading.
How do you stay updated with new wireless standards?
I follow standards bodies, read technical journals, attend conferences, and take professional courses. Hands-on experimentation with new tools also helps me understand practical implications.
Explain the trade-off between bandwidth and power efficiency.
Wider bandwidth enables higher data rates but often requires more power and spectrum. Engineers balance these factors to meet performance targets while respecting regulatory and energy constraints.
