Jio Field Support Engineer Interview Questions and Answers

The type of transformer used in telecom tower sites is typically a step-down transformer.

• Step-down transformers are used to reduce the high voltage from the power grid to a lower voltage suitable for telecom equipment.

• These transformers are usually single-phase and have a power rating of a few kilovolt-amperes (kVA).

• They are designed to provide a stable and reliable power supply to the telecom equipment at the tower si...read more

SMPS stands for Switched Mode Power Supply, which is an electronic power supply that uses a switching regulator to convert electrical power efficiently.

• SMPS is commonly used in electronic devices such as computers, televisions, and mobile phones.

• It uses a switching regulator to convert AC power to DC power.

• SMPS is more efficient than traditional linear power supplies.

• It can be designed to provide different output volta...read more

A rectifier is an electrical device that converts alternating current (AC) to direct current (DC).

• Rectifiers are commonly used in power supplies and electronic devices.

• They typically consist of diodes that allow current to flow in only one direction.

• Rectifiers can be half-wave or full-wave, depending on the number of diodes used.

• Examples of rectifiers include bridge rectifiers, vacuum tube rectifiers, and solid-state r

PAC stands for Programmable Automation Controller, a type of industrial control system used for automation and monitoring.

• PACs are similar to PLCs but have more advanced capabilities such as data processing and communication.

• They are used in various industries including manufacturing, energy, and transportation.

• PACs can be programmed using various languages such as ladder logic, structured text, and C++.

• Examples of PAC...read more

VSWR stands for Voltage Standing Wave Ratio. It is a measure of how well the impedance of a transmission line matches the input/output impedance of the connected device.

• VSWR is a ratio of the maximum voltage to the minimum voltage in a standing wave pattern along a transmission line.

• It is used to measure the efficiency of power transfer between a device and a transmission line.

• A VSWR of 1:1 indicates perfect impedance ...read more

RSL stands for Received Signal Level, which is a measure of the strength of a received radio signal.

• RSL is commonly used in the telecommunications industry to measure the strength of a signal received by a device.

• It is usually measured in decibels (dB) and can be used to determine the quality of a signal.

• RSL can be affected by various factors such as distance, obstacles, and interference.

• For example, a weak RSL may ind...read more

RRU stands for Remote Radio Unit, a component of a base station used in wireless communication networks.

• RRU is responsible for transmitting and receiving radio signals to and from the antenna.

• It is usually located at the top of a cell tower or on a rooftop.

• RRUs are used in technologies such as 4G LTE and 5G.

• They are designed to be compact and energy-efficient.

• RRUs can be easily replaced or upgraded without affecting th...read more

ODU stands for Outdoor Unit. It is a component of a wireless communication system that is installed outside a building or structure.

• ODU is responsible for transmitting and receiving signals between the indoor unit and the base station.

• It is designed to withstand harsh weather conditions and is usually mounted on a rooftop or a pole.

• ODUs are commonly used in microwave and satellite communication systems.

• Examples of ODU ...read more
