This book provides the essential design techniques for radio systems that
operate at frequencies of 3 MHz to 100 GHz and which will be employed in
the telecommunication service. We may also call these wireless systems,
wireless being synonymous with radio, Telecommunications is a vibrant indus-
try, particularly on the ‘‘radio side of the House.’’ The major supporter of this
upsurge in radio has been the IEEE and its 802 committees. We now devote
? . an entire chapter to wireless LANs WLANs detailed in IEEE 802.11. We
also now have subsections on IEEE 802.15, 802.16, 802.20 and the wireless
? . ? metropolitan area network WMAN . WiFi, WiMax,, and UWB ultra wide-
. band are described where these comparatively new radio specialties are
demonstrating spectacular growth.

In 2001, Orange, a UK mobile network operator, announced the “Orange
at Home” project, a smart House incorporating the latest technology
wizardry built some 20 miles north of London. It was intended to be more
than a mere showcase, with plans for real families to move in and live
with the smart home. My then research establishment, the Digital World
Research Centre at the University of Surrey, was commissioned to study
how these families reacted to their new home, and to report lessons for
the future development of smart homes and smart home technologies.

Over the past few decades there has been an exponential growth in service robots
and smart home technologies, which has led to the development of exciting new
products in our daily lives. Service robots can be used to provide domestic aid for
the elderly and disabled, serving various functions ranging from cleaning to enter-
tainment. Service robots are divided by functions, such as personal robots, field
robots, security robots, healthcare robots, medical robots, rehabilitation robots and
entertainment robots. A smart home appears “intelligent” because its embedded
computers can monitor so many aspects of the daily lives of Householders. For
example, the refrigerator may be able to monitor its contents, suggest healthy alter-
natives and order groceries. Also, the smart home system may be able to clean the
House and water the plants.
