Tutorial Proposal

Title: -

“Global Mobile Broadband with LTE”

Abstract: -

Long Term Evolution (UMTS Release 8) offers a smooth evolution path towards 4G for

service providers deploying 3GPP and non-

3GPP standard’s technologies. LTE proposes

to use an advanced radio interface technology based on OFDMA on the downlink, SC-

FDMA on the uplink and a flat IP based network architecture. Some of the important

reasons behind the choice of OFDMA are its ability to overcome wireless channel

related fading issues, support for tight frequency reuse leading to better spectral

efficiency, support for users with different QoS requirements, and the ability to

integrate multiple antenna technology (MIMO), a key enabler. LTE intends to utilize a

flat IP based network architecture to meet the stringent technical requirements of next

generation wireless systems. LTE promises long-term revenue stability and growth by

creating avenues for new value added services. For 250+ service providers who have

already deployed/committed to the 3GPP technologies it provides scope for harmonious

co-existence with legacy networks. This tutorial presentation would provide an in-depth

overview of the important technologies behind LTE systems and how they are proposed

to be implemented.

Duration: -

Half day (210 Minutes)

Goal and Objectives: -

The objective of the proposed tutorial is to provide an in-depth understanding of the

key technical concepts behind very high speed all data LTE networks. With the

conference aim to foster research in ultra modern wireless communication, the topic of

this presentation would be of great interest to all the participants.

Scope: -

This tutorial would be suitable for academicians and practitioners with exposure to any

cellular or broadband wireless technology.

Teaching Method: -

It is proposed to be organized as a three hour and thirty minutes long session divided

into two halves. Multimedia presentation is proposed to be used.
