  • Q3. What is X2 interface
  • Ans. 

    X2 interface is a communication interface between two eNodeBs in LTE network.

    • X2 interface is used for inter-cell handover and load balancing.

    • It is a point-to-point interface that connects two eNodeBs.

    • X2 interface is used for exchanging control and user plane data between eNodeBs.

    • It is a critical interface for LTE network performance and reliability.

    • X2 interface supports various protocols such as S1AP, GTP, and RANAP.

  • Answered by AI
  • Q4. Channels of LTE
  • Ans. 

    LTE has 20 MHz bandwidth divided into 100 resource blocks. Each resource block has 12 subcarriers and 7 symbols.

    • Coverage measures the area where the network signal is available.

    • Call setup success rate measures the percentage of succes...

  • Answered by AI
  • Q6. What is CSFB?
  • Ans. 

    CSFB stands for Circuit Switched Fallback, a technology that allows LTE devices to fallback to 2G or 3G networks for voice calls.

    • CSFB is used when a LTE device is unable to make a voice call over the LTE network.

    • It allows the device to switch to a 2G or 3G network for voice calls.

    • CSFB is a temporary solution until VoLTE (Voice over LTE) becomes more widely available.

    • CSFB can cause call setup delays and impact the user

  • Answered by AI
  • Q7. Why OFDMA technique used in LTE?
  • Ans. 

    OFDMA is used in LTE to improve spectral efficiency and support multiple users simultaneously.

    • OFDMA allows for multiple users to share the same frequency band by dividing it into smaller subcarriers.

    • It also enables dynamic allocation of subcarriers to users based on their bandwidth requirements.

    • This results in better spectral efficiency and higher data rates.

    • OFDMA is also resistant to interference and fading, making it...

  • Q8. Differentiate FDD & TDD
  • Ans. 

    FDD and TDD are two different duplexing techniques used in wireless communication.

    • FDD stands for Frequency Division Duplexing and TDD stands for Time Division Duplexing.

    • In FDD, separate frequency bands are used for uplink and downlink communication, while in TDD, the same frequency band is used for both uplink and downlink communication.

    • FDD is used in technologies like 2G, 3G, and 4G LTE, while TDD is used in technolog...
