Planning the LTE Radio Network Duration: 3 days

Planning the LTE Radio Network
CONTENT
It is commonly accepted that the next leap in wireless networks will come from an evolved network topology. LTE Heterogeneous Network (HetNet), improved by LTE-Advanced, is drawing significant attention to optimize network performance, especially in cases of unequal user or traffic distribution. Such deployment strategy requires planners to consider new mind-sets and challenges. This renewed course provides the key concepts of LTE HetNet included in 3GPP Rel. 8/9 and LTE-Advanced, where a special attention is given to practical considerations to succeed planning complex hierarchical structured LTE radio networks. Alongside, this course covers LTE coverage and capacity dimensioning calculations, based not only on the LTE link-budget aspects and MCS/SNR vs. Resource Block (RB) trade off, but also on the LTE Advanced new features impact. Initial radio interface parameter planning and optimization is also included, e.g. PCI planning.

Engaging hands-on exercises and new case-studies analysis make this course an highly qualified practical LTE planning experience within a classroom.

WHO SHOULD ATTEND
This intermediate to advanced course is better suited for telecom professionals already working with LTE radio network planning, dimensioning and optimization. Newcomers, integrators and managers will also appreciate this course as it provides a complete end-to-end radio planning details without being too difficult to follow.

PREREQUISITES
