10+ TechPIO Interview Questions and Answers

The download speed of 1800MHz depends on various factors and cannot be determined solely based on the frequency.

• Download speed is influenced by network infrastructure, signal strength, and device capabilities.

• Higher frequency bands like 1800MHz generally offer faster download speeds compared to lower frequency bands.

• However, other factors such as network congestion and distance from the cell tower can affect the actual download speed.

• To determine the download speed at 1800MHz...read more

Interference is the phenomenon where two or more waves combine to form a resultant wave, resulting in constructive or destructive interference.

• Interference occurs when waves meet and interact with each other.

• Constructive interference happens when the peaks of two waves align, resulting in a larger amplitude.

• Destructive interference occurs when the peaks of one wave align with the troughs of another, resulting in a smaller amplitude.

• Interference can be observed in various fiel...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.

A channel is a pathway or medium through which information or signals are transmitted.

• Channels can be physical, such as cables or wires, or they can be virtual, such as wireless communication.

• Channels are used in various fields, including telecommunications, electronics, and computer networking.

• Examples of channels include fiber optic cables, radio waves, and internet protocols.

Handover is the process of transferring control or responsibility from one person or system to another.

• Handover is common in various fields, including engineering, construction, and telecommunications.

• In engineering, handover refers to the transfer of a project or task from one engineer or team to another.

• During handover, relevant information, documentation, and responsibilities are passed on to ensure a smooth transition.

• Handover can involve physical handover of equipment, s...read more

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

Intra handover refers to the process of transferring control of a communication session from one base station to another within the same network.

• Intra handover is a crucial aspect of mobile communication systems.

• It ensures seamless connectivity and uninterrupted service for mobile users.

• During intra handover, the control of a communication session is transferred from the current base station to a neighboring base station within the same network.

• This transfer is necessary when...read more

Swapping is the process of exchanging the values of two variables.

• Swapping is commonly used in programming to rearrange data or sort elements.

• It can be done using a temporary variable or using arithmetic operations.

• Example: Swapping two numbers - a = 5, b = 10. After swapping, a = 10, b = 5.

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

An electronic mechanic is a skilled technician who repairs and maintains electronic equipment and systems.

• An electronic mechanic is responsible for troubleshooting and diagnosing issues with electronic devices.

• They repair and replace faulty components and perform regular maintenance to ensure proper functioning.

• Electronic mechanics may work on various equipment such as computers, televisions, radios, and industrial machinery.

• They need to have a strong understanding of electro...read more

Transformers are electrical devices that transfer electrical energy between two or more circuits through electromagnetic induction.

• Transformers change the voltage level of an alternating current (AC) electrical signal.

• They can step up or step down the voltage depending on the turns ratio of the transformer.

• Transformers are used in power distribution systems to transmit electricity at high voltages and then step it down for consumer use.

• They are also used in electronic devices...read more
