DOWNLOAD EBOOK →Complete Asterisk Training is a new edition of the Configuration Guide for Asterisk PBX. The reason for change the name is to match the name of the online training available on Udemy. So this book is part of a three part training system, eLearning, Text Book and Lab Guide. Why a different book about Asterisk? Most books are not oriented to teach the reader on how to build a complete PBX. They present many concepts, but not with a story, an objective. I have based this book in the old training guides from Novell. So it has a start where you install Asterisk, then you create extensions, trunks, dialplan until you complete a fully functional free and open source PBX. Then we go to more advanced concepts. In this book you will learn: - How to install Asterisk- How to register extensions- How to connect SIP trunks- How to create a dial plan to send and receive calls- How to configure analog and digital channels- How to configure SIP, IAX and PJSIP- How to use Asterisk behind NAT and clients behind NAT- How to use PBX features such as tranfer, capture, parking, conference- How to configure Call queues and Agents - How to generate CDRs to a database using ODBC drivers- How to develop simple AGIs and AMIs to connect your programs- How to secure Asterisk using Fail2Ban, IPTABLES, TLS and SRTP- How to use Asterisk Real Time to read the configuration from a databaseWe cover the latest version, Asterisk 16, a Long Term Support version. I hope you use this version for a long time. This book has more than 10 years, the first edition was in 2006 and since then it has been updated once each 4 or 5 years. This book has two companions. A training on Udemy with the same name and a Lab Guide on github, more details inside the book . I sincerely hope you enjoy. Flavio E. Goncalves

DOWNLOAD EBOOK →The high level of technical detail included in standards specifications can make it difficult to find the correlation between the standard specifications and the theoretical results. This book aims to cover both of these elements to give accessible information and support to readers. It explains the current and future trends on communication theory and shows how these developments are implemented in contemporary wireless communication standards. Examining modulation, coding and multiple access techniques, the book is divided into two major sections to cover these functions. The two-stage approach first treats the basics of modulation and coding theory before highlighting how these concepts are defined and implemented in modern wireless communication systems. Part 1 is devoted to the presentation of main L1 procedures and methods including modulation, coding, channel equalization and multiple access techniques. In Part 2, the uses of these procedures and methods in the wide range of wireless communication standards including WLAN, WiMax, WCDMA, HSPA, LTE and cdma2000 are considered. An essential study of the implementation of modulation and coding techniques in modern standards of wireless communication Bridges the gap between the modulation coding theory and the wireless communications standards material Divided into two parts to systematically tackle the topic - the first part develops techniques which are then applied and tailored to real world systems in the second part Covers special aspects of coding theory and how these can be effectively applied to improve the performance of wireless communications systems
