QCI7 specifically is used for Internet of Things (IoT) applications
- 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...

- 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. What is 4G parameters and explain
- Ans.
4G parameters are settings that control the performance of a 4G network.
4G parameters include things like handover thresholds, power control settings, and modulation schemes.
These settings can be adjusted to optimize network performance and improve user experience.
Examples of 4G parameters include RSRP, RSRQ, SINR, and MCS.
RSRP (Reference Signal Received Power) is a measure of the signal strength at the receiver.

- 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.
