Hello everyone - LTE optimization
The goal of the optimization process is to improve the performance of the LTE network and maintain the quality of service provided to customers.
The process of optimization in mobile networks is generally divided into two stages, the first is before the network is turned on and pre-launch optimization is loaded with clients, and the second is after the network is post-launch optimization, which is continuous.
Often the required changes in the network during the pre-launch optimization process are physical, such as adjusting the angles of the antennas, azimuth and elevation angle or their inclination.
From different network devices system KPIs.
Adjustments are made at the single site verification level and at the cluster level (often the cluster contains from 15 to 25 stations).
In the second stage of optimization, most of the adjustments are in the network parameters values, and the system KPIs are relied upon in addition to the drive test sometimes.
In addition to customer complaints.
Optimization aims to:
coverage improvements: by reducing the areas that are not covered by the signal of eNB mobile stations, and reducing the areas covered by more than one eNB coverage overlapping station - and others.
interference reduction: interference affects data transmission speeds for clients in addition to increasing the error rate.
Increasing the success rate of transferring calls between wireless stations, during the client's movement during calls or during Internet connection.
Increase the capacity of wireless stations to increase the number of subscribers at the level of eNB wireless stations.
Network quality improvements: Focusing on a set of values and improving them, such as packet loss rate, average packet delay, and other values.
The optimization stage is generally preceded by the network planning stage.
In the event of insufficient network planning, a very heavy burden falls on the optimization engineer.
Optimizer must have strong technical knowledge to carry out his task in improving network performance effectively.
