Popular Designations

Q1. What steps would you take to observe the field if you were to visit it?

Ans.

I would conduct thorough field observations by following a structured approach.

  • Create a checklist of key areas to observe such as customer interactions, employee performance, and store layout.

  • Interact with employees and customers to gather feedback and insights.

  • Review sales data and inventory levels to assess performance and identify areas for improvement.

  • Observe competitor activity and market trends to stay informed and competitive.

  • Document findings and create a report with ...read more

Q2. Why is a Base Station Controller (BSC) unnecessary in a 4G network?

Ans.

A BSC is unnecessary in a 4G network because the functions of a BSC are integrated into the base station in 4G technology.

  • In 4G networks, the functions of a BSC are handled by the eNodeB (Evolved Node B), which combines the functionalities of both the BSC and the Node B in previous generations.

  • The eNodeB in a 4G network directly communicates with the core network, eliminating the need for a separate BSC.

  • This integration simplifies the network architecture, reduces latency, an...read more

Q3. What are the uplink and downlink speeds in a 4G network?

Ans.

Uplink and downlink speeds in a 4G network typically range from 5-50 Mbps and 50-100 Mbps respectively.

  • Uplink speeds in a 4G network usually range from 5-50 Mbps

  • Downlink speeds in a 4G network typically range from 50-100 Mbps

  • Speeds can vary based on network congestion, location, and device capabilities

Q4. What is beamwidth in the context of antenna theory?

Ans.

Beamwidth in antenna theory refers to the angular width of the main lobe of the radiation pattern.

  • Beamwidth is typically measured in degrees and can be either horizontal or vertical.

  • It is an important parameter as it determines the coverage area and directionality of the antenna.

  • A narrower beamwidth indicates a more focused radiation pattern, while a wider beamwidth provides broader coverage.

  • For example, a directional antenna may have a narrow beamwidth of 30 degrees, while a...read more

Q5. What is MIMO (Multiple Input Multiple Output) technology?

Ans.

MIMO technology is a wireless communication technology that uses multiple antennas to improve data transfer rates and signal reliability.

  • MIMO technology involves multiple antennas at both the transmitter and receiver to improve communication performance.

  • It allows for multiple data streams to be transmitted simultaneously, increasing data transfer rates.

  • MIMO technology can also improve signal reliability by using spatial diversity to combat fading and interference.

  • Examples of ...read more

Q6. What does a 4G GSM network diagram illustrate?

Ans.

A 4G GSM network diagram illustrates the architecture and components of a fourth-generation Global System for Mobile Communications network.

  • Illustrates the various network elements such as base stations, mobile switching centers, and routers

  • Shows the connections between these elements to facilitate data and voice communication

  • Demonstrates the flow of data packets and signaling within the network

  • Includes details on how different network entities interact to provide seamless mo...read more

Q7. What is Voltage Standing Wave Ratio (VSWR)?

Ans.

VSWR is a measure of how efficiently radio-frequency power is transmitted from a power source, through a transmission line, to a load.

  • VSWR is calculated as the ratio of the maximum voltage to the minimum voltage along a transmission line.

  • It is used to measure the impedance mismatch between a transmission line and its load.

  • A VSWR of 1:1 indicates a perfect match, while higher values indicate poor matching.

  • VSWR is important in ensuring maximum power transfer and minimizing sign...read more

Q8. What is a threshold?

Ans.

A threshold is a point at which a change or effect occurs.

  • A threshold is a specific point or level that must be reached for a particular action or result to happen.

  • It can also refer to a limit or boundary that must be crossed for something to occur.

  • For example, a company may have a sales threshold that must be met in order to receive a bonus.

  • In biology, a threshold may refer to the minimum amount of a stimulus needed to produce a response.

Q9. What is an E-Node B?

Ans.

An E-Node B is a hardware component in LTE networks that connects mobile devices to the core network.

  • E-Node B stands for Evolved Node B.

  • It is responsible for radio communication with mobile devices.

  • E-Node Bs are connected to the EPC (Evolved Packet Core) in LTE networks.

  • They handle tasks such as radio resource management and handovers between cells.
