4G - Long-Term Evolution (LTE) Network Planning

COURSE OVERVIEW

For LTE rollout deployment, operators should be all set. This requires an in-depth knowledge of the planning considerations involved. It provides, in a theoretical and practical manner, the parameters related to RF coverage that should be taken into account for LTE network planning.

The course starts off with a brief skim of LTE system architecture and LTE air interface properties. It is followed by an uplink and downlink link budget discussion at the next. This course is in the form of online hands-on practice on Link budget calculations and formulations to determine the sensitivity of the expected variables and to solve specific case studies.

TARGET AUDIENCE

This course is intended for managers, engineers, and technicians in the mobile telecommunication industry.

Course Prerequisites

Participants must have attended ‘4G LTE Technical Overview,’ or they must have the other equivalent experience of working on the LTE systems.

Expected Accomplishments

Elaborate on the LTE Physical Layer Structure
List down the principles of OFDMA and SC-FDMA.
Calculate LTE link budgets for the uplink and downlink, taking into account the channel bandwidth, TX, RX parameters, and transmission transmission.
Calculate SNR consumption for a given cell edge throughput
Find the fade margin of a given cell edge probability using an estimation method
Describe about allocation of resources in up-link and down-link
Provide the details on the LTE frame format for the downlink as well as uplink.
LTE, both uplink and downlink coverage and capacity calculations are to be done.
List out the factors that primarily affect cell capacity
Evaluate the cell capacity
Calculate the number of sites according to the coverage and the capacity.
