Drive Test Engineer Interview Questions and Answers

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

There are two main types of swap: interest rate swaps and currency swaps.

• Interest rate swaps involve exchanging interest rate payments, often to switch from a fixed to a floating rate or vice versa.

• Currency swaps involve exchanging principal and interest payments in one currency for another, often to hedge against exchange rate risk.
