Today, wireless infrared transmission has entered our homes,
offices, industry and health care, with applications in the field
of remote control, telemetry and local communication. Low-Power
Wireless Infrared Communications is about the underlying
technology. As most equipment is battery-powered, the emphasis is
on power optimization of the infrared transmission system. System
parameters as well as environmental parameters that determine the
eventual transmission quality are identified, to facilitate
well-reasoned system design. Many design rules, based on
calculations, measurements and simulations, are presented to help
the designer push the performance close to the limits set by nature
and the available technology. Firstly, the basic transmission link
is introduced, and strategies to optimize its signal-to-noise ratio
are discussed. Lighting flicker is identified as a possible source
of interference. Then, receiver noise and bandwidth are discussed.
It is argued that noise optimization and bandwidth optimization do
not necessarily conflict. The following chapters provide the reader
with an overview of modulation and synchronization techniques.
Pulse position modulation is recognized as an attractive technique
for low-power purposes. As receiver synchronization in those
systems is a subject hardly covered by literature, an in-depth
discussion of possible synchronization subsystems is included. This
book is essential reading for researchers and designers of infrared
communication systems and those who are involved in standardization
activities (Infrared Data Association, IrDA). For those who are new
to the area, the first chapter serves as an ideal introduction.
