Drive Test Engineer Interview Questions and Answers

Auditing and optimizing a site involves assessing performance, coverage, and user experience to enhance network efficiency.

• Check signal strength and quality across different locations to ensure optimal coverage.

• Analyze traffic patterns to identify congestion points and optimize resource allocation.

• Evaluate handover success rates to minimize dropped calls and improve user experience.

• Inspect hardware and software configurations for compliance with best practices.

• Conduct drive t...read more

Tower height, antenna height, and azimuth of all sectors are checked for drive test engineer role.

• Tower height is measured using specialized equipment such as a laser range finder.

• Antenna height is measured using a tape measure or a clinometer.

• Azimuth of all sectors is measured using a compass or a GPS device.

• The data collected is used to ensure proper network coverage and performance.

• Any discrepancies found are reported to the appropriate team for correction.

Mechanical tilt can be checked physically while electrical tilt can be checked using a spectrum analyzer.

• Mechanical tilt can be checked by physically measuring the angle of the antenna

• Electrical tilt can be checked by using a spectrum analyzer to measure the signal strength at different frequencies

• Adjustments can be made to the electrical tilt by changing the phase shift of the signal

• Mechanical tilt can also be adjusted by physically adjusting the angle of the antenna

Azimuth of all sectors can be checked using a compass or specialized tools.

• Use a compass to determine the direction of each sector

• Specialized tools like antenna alignment tools can also be used

• Compare the measured azimuth with the expected azimuth for each sector

• Make necessary adjustments to ensure proper alignment
