LTE Foundation, PLMN, MIB/SIB1, Cell Selection & Reselection | 4G E2E Signaling Session 1

Описание: Welcome to Session 1 of the 4G E2E Signaling Course. In this session, we build the essential LTE foundation concepts needed before going into detailed end-to-end signaling procedures such as attach, bearer setup, handover, and service request.

This video explains how the UE in LTE/4G finds the network, selects a PLMN, performs cell search, reads system information, decodes MIB and SIB1, and applies cell selection and cell reselection criteria in idle mode. It also connects theory with drive test log analysis, making it highly useful for telecom engineers, RF engineers, optimization engineers, drive test engineers, and anyone learning LTE signaling.

In this session, you will learn:
4G foundation concepts overview
Key LTE processes and general concepts
PLMN selection
Cell search
System Information Acquisition
MIB content
SIB1 periodicity and content
Cell selection overview
MIB parameters from drive test
SIB1 parameters from drive test
Cell selection parameters from drive test
Cell reselection overview
Cell reselection based on ranking
Cell reselection based on absolute priority
SIB3 and SIB5 parameters from drive test
Idle mode tuning and KPI impact

This video is especially useful if you want to understand:
LTE idle mode behavior, PLMN identities, MCC/MNC, TAC, PCI, system frame number, QRxLevMin, cell barring, reselection priorities, ranking criteria, SIB3, SIB5, drive test decoding, LTE troubleshooting, and KPI optimization.

Whether you are preparing for telecom interviews, improving your LTE troubleshooting skills, or learning how to analyze 4G drive test logs and signaling messages, this session gives you a strong practical foundation.
