25 Slide UMTS LTE Tutorial

Printed or Electronic Version (3.9MB) Available - Electronic Version has Color Diagrams

Description

This book explains the basic components, technologies used, and operation of UMTS LTE systems. You will discover why mobile telephone service providers are upgrading their 2nd and 3nd generation digital mobile to a more efficient and feature rich UMTS LTE generation system.

Discover the key features that LTE systems provide that go beyond the capabilities of existing 2G and 3G mobile systems such as ultra high-speed internet (100 Mbps+), television (multicast video), and low latency services (packet voice).

Related Books

Explained are the physical and logical radio channel structures of the LTE systems along with the basic frame and slot structures. Described are the fundamental capabilities and operation of the LTE radio channel including channel coding, modulation types, and low latency transmission processes.

You will discover the key functional sections of a LTE network component and how they communicate with each other. Learn how and why LTE systems separate control signing channel from user data channels. You will also discover how LTE systems can interoperate with existing mobile systems which simplify the migration plan from less efficient mobile systems to more cost effective and capable LTE systems.

Learn LTE systems can evolve into 4th generation ultra broadband systems using spatial division multiple access (SDMA) technology which will eventually able to provide up to 1 Gbps data transfer rates. Some of the most important topics featured in this book are:

How LTE systems operate
New LTE services such as multicast video
The LTE radio channel structure
Types of physical and logical channels
LTE network components
Network components and their connections
How GSM and UMTS WCDMA can be upgraded to LTE technology

LTE Key Features

This figure shows that some of the key features of the UMTS LTE system include increased data transmission rate, spectrum flexibility, reduced latency, and lower costs. Increased data transmission rates are possible through the use of wider radio channels and efficient modulation types. Spectrum flexibility allows for the use of variable channel bandwidth and channel duplexing types. Reduced latency is enabled by the use of more efficient channel control assignment processes. Lower cost is provided from the ability to serve more customers using a reduced number of radio channels and through automated system configuration processes.

Upgrading GSM and 3G to LTE

This figure shows how a 3G and GSM system can be upgraded to offer UMTS LTE services. This diagram shows that typically 1 to 4 wide WCDMA or 2 or more narrow GSM channels are typically removed to allow a very wide 20 MHz UMTS LTE channel to be added. This example also shows that a separate base station assembly is added to communicate with a UMTS evolved packet core (EPC).
