LTE Inverted Sector Analysis: How to Ensure Everything is Functioning Perfectly?
During the activation of LTE sites and some post-activation checks, detailed sector analysis is essential to ensure network quality and user experience.
Here are the key steps we follow to make sure everything is in order!
-
Handover (HO) Counters To ensure sectors are configured correctly, one of the first analyses involves checking the HO counters. The handover between cells needs to occur smoothly, without failures or inconsistencies, both outbound and inbound. If the HO attempt and HO success counters are within expected standards, we can proceed safely.
-
Serial Inversion The next critical step is to check for possible serial inversions in the RRUs. We use specific commands to ensure each sector is linked to the correct serial, avoiding any physical inversion that could compromise cell performance. If the serials are where they should be, we move forward.
-
SRS (Sounding Reference Signal) Tests SRS tests are essential to validate uplink quality. We monitor these tests to identify coverage issues or sector configuration failures. SRS results within parameters indicate that the configuration is correct and communication between the station and users is efficient.
-
Traffic Behavior on Carriers A graphical analysis of traffic behavior on carriers over a specific time window is crucial to identify potential anomalies. Advanced tools help us visualize user distribution and bandwidth usage, ensuring there are no overloads or routing failures between sectors. If everything appears stable and within expectations, we conclude there is no sector inversion!
-
Conclusion: When all these tests and checks are successful β from HO counters to graphical traffic analysis β we can confidently state that the sectors are correctly configured and ready to deliver the best user experience.
