I appeared for an interview in Jul 2021.
I use various tools for drive test including network scanners, spectrum analyzers, and GPS receivers.
Network scanners to measure signal strength and quality
Spectrum analyzers to detect interference and noise
GPS receivers to track location and speed
Smartphones with testing apps to collect data
Laptop with specialized software to analyze data
RF power meters to measure power levels
Antenna testers to check antenna performan

Array antennas are designed by arranging multiple antenna elements in a specific configuration to achieve desired radiation pattern and performance.
Determine the desired radiation pattern and performance requirements
Select the type of array configuration (linear, planar, conformal, etc.)
Calculate the spacing between antenna elements based on wavelength and array factor
Design feeding network to properly feed each antenn...
Antenna array design involves elements such as element spacing, beamforming techniques, and array geometry.
Element spacing determines the directivity and beamwidth of the array.
Beamforming techniques like phase shifting and amplitude tapering help steer the beam in a desired direction.
Array geometry, such as linear, planar, or conformal arrays, affects the radiation pattern and polarization.
Antenna array design also co...
The tilt in the base station antenna can be adjusted by physically changing the angle of the antenna.
Tilt can be adjusted by loosening the bolts on the antenna mount and manually changing the angle of the antenna
Specialized tools like tilt meters can be used to ensure the correct angle is achieved
Remote electrical tilt (RET) systems can also be used to adjust the tilt of the antenna electronically
