RF Drive Test Engineer Interview Questions and Answers

To improve coverage for a customer not getting good coverage, focus on optimizing KPIs such as RSRP, RSRQ, SINR, and handover success rate.

• Optimize RSRP (Reference Signal Received Power) by adjusting antenna tilt and orientation.

• Improve RSRQ (Reference Signal Received Quality) by reducing interference and optimizing cell overlap.

• Enhance SINR (Signal-to-Interference plus Noise Ratio) by minimizing noise and interference sources.

• Increase handover success rate by optimizing hand...read more

RSRP stands for Reference Signal Received Power and represents the power of the received signal from the serving cell.

• RSRP is measured in dBm

• The range of RSRP is typically between -140 dBm to -44 dBm

• Higher RSRP values indicate stronger signal strength

Microwave frequency refers to the frequency range of electromagnetic waves typically used in microwave communication systems.

• Microwave frequency typically ranges from 1 GHz to 300 GHz.

• Antenna types commonly used in microwave communication include parabolic antennas, horn antennas, and patch antennas.

• Power factor is a measure of how effectively electrical power is being used in a circuit.

• In digital electronics, signals are represented by discrete values (0s and 1s) to perform ...read more
