书籍 Building Next-Generation Converged Networks
The telecommunications industry has seen a rapid boost within the last decade. New realities
and visions of functionalities in various telecommunications networks have brought forward the
concept of next-generation networks (NGNs). The competitions among operators for support-
ing various services, ...
书籍 ComSoc+Guide+to+Next+Generation+Optical+Transport
Many times I have been asked to explain “ briefl y ” how SDH, SONET, and the
OTN “ exactly ” work. The questions came mainly from new colleagues, stu-
dents, and users of these technologies, personally or via the usenet newsgroup
comp.dcom.sdh - sonet. I could have referred them to the standards ...

In the preparation of this book, our objective was to provide an advanced understanding of emerging
telecommunications systems, their significance, and the anticipated role these systems will play in the
future. With the help of our talented associated editors and contributors, we believe we have ac ...
书籍 Essentials+of+Radio+Wave+Propagation
The objective of this book is to allow the reader to predict the received
signal power produced by a particular radio transmitter. The first two
chapters examine propagation in free space for point-to-point and
point-to-area transmission, respectively. This is combined with a dis-
cussion regarding ...
