This course defines a practical approach to LTE RAN capacity planning, and applies the concepts to design and augment LTE network. Throughout the class, students build up RAN capacity models based on typical network operations, determining the eNB, air interface and backhaul requirements needed to support the expected user traffic and signaling demands. In addition, E-UTRAN counters and KPIs are defined to allow operators to measure and assess the performance of the network, to identify potential system bottlenecks. Typical LTE operations and mobility requirements are factored in, resulting in a RAN design that meets the expected demand and is capable of growing to support future services. This certification workshop utilizes several hands-on exercises to build a capacity planning model and concludes with a certification assessment. Required Equipment: PC laptop
Learning Objectives
After completing this course, the student will be able to: • Define the key components of the LTE RAN network models and determine the necessary inputs and expected outputs • Create a subscriber demand (traffic) model and estimate the impact on the user plane for both data and VoIP services • Map typical LTE signaling operations to the corresponding nodes and interfaces and model their impacts on the control plane • Determine the air interface capacity and expected cell throughput for the subscriber demand • Estimate VoLTE user capacity • Use network counters and KPIs to assess potential air interface and software licensing bottlenecks
Intended Audience
This course is designed for RAN and systems engineers involved in capacity planning, design, deployment and operation of LTE network.
Suggested Prerequisites
• LTE Overview (eLearning) • Mastering LTE Air Interface (Instructor Led)
