(2 Questions)
- Q1. How to solve handover & drop call
- Ans.
Handover and drop call issues can be solved by optimizing network parameters, improving coverage and capacity, and troubleshooting hardware and software problems.
Optimize handover parameters such as handover margin, time-to-trigger, and hysteresis
Improve coverage by adding more base stations or adjusting antenna tilt and azimuth
Increase capacity by adding more carriers or sectors
Troubleshoot hardware issues like faulty...
- Q2. Check relation with inter & intra cell term point & anchor baseline
- Ans.
The relation between inter and intra cell term point and anchor baseline is important in RF optimization.
Inter cell term point refers to the point where the signal from one cell ends and the signal from another cell begins.
Intra cell term point refers to the point within a cell where the signal quality starts to degrade.
Anchor baseline is a reference point used to measure the performance of a network.
The relation betwe...

- Q1. RACH PROCEDURE
- Ans.
RACH procedure is used for initial access to the network by a UE.
RACH stands for Random Access Channel.
UE sends a RACH preamble to the network to request access.
The network responds with a RACH response message.
RACH procedure is used for both uplink and downlink transmission.
Optimizing RACH parameters can improve network performance.
- Q2. Handover Parameters
- Q3. Handover events
- Q4. How to improve DL throughout in good RF condition
- Ans.
To improve DL throughput in good RF condition, optimize antenna tilt, increase sector capacity, and reduce interference.
Optimize antenna tilt to improve signal strength and reduce interference
Increase sector capacity by adding more carriers or using advanced modulation techniques
Reduce interference by identifying and mitigating sources of interference
Ensure proper network planning and optimization to maximize DL throug...
- Q5. How to improve VDR
- Ans.
VDR can be improved by optimizing network parameters and reducing interference.
Optimize antenna tilt and azimuth angles
Adjust transmit power levels
Reduce interference from neighboring cells
Implement advanced interference cancellation techniques
Use frequency hopping to avoid interference
Deploy more base stations to improve coverage
Upgrade network hardware and software
Perform regular network audits and optimizations
- Q6. How to improve BLER
- Ans.
To improve BLER, optimize the radio network by adjusting parameters and improving coverage.
Optimize radio network parameters such as power control, handover parameters, and modulation schemes
Improve coverage by adding more base stations or adjusting antenna tilt and orientation
Reduce interference by identifying and mitigating sources of interference
Perform regular network audits and drive tests to identify and address ...

- Q2. What is MME Drop and eNodeB Drop in LTE ?
- Ans.
MME Drop and eNodeB Drop in LTE refer to the loss of connection between the mobile device and the network due to various reasons.
MME Drop refers to the loss of connection between the mobile device and the Mobility Management Entity (MME) in LTE network.
eNodeB Drop refers to the loss of connection between the mobile device and the eNodeB (base station) in LTE network.
These drops can occur due to factors such as poor sig...
