Have you been reading the latest science magazines and noticed that the
word “nano” has become as ubiquitous as the word “calorie” in a diet
book? Are you looking for the latest hot investment opportunity and you’ve
heard that something called nanotechnology will someday revolutionize our
lives, and quite possibly your portfolio?
Well, you’ve come to the right place! Nanotechnology For Dummies is a fantastic
way to get beyond all the hype and really understand what nanotechnology
is and where it’s headed.
As mentioned in Chapter 1,VSAT networks usually offer communications service between user terminals. These terminals generate baseband signals that are analogue or digital,predominantly digital.
Wireless sensor networks promise an unprecedented fine-grained interface
between the virtual and physical worlds. They are one of the most rapidly developing
new information technologies, with applications in a wide range of fields
including industrial process control, security and surveillance, environmental
sensing, and structural health monitoring. This book is motivated by the urgent
need to provide a comprehensive and organized survey of the field.
