Information networking has emerged as a multidisciplinary diversified area of research o t
a
over the past few decades. From traditional wired telephony to cellular voice telephony r n Communications Networks
E
and from wired access to wireless access to the Internet, information networks have
m d
profoundly impacted our lifestyles as they have undergone enormous growth. To
understand this technology, students need to learn several disciplines and develop an e in for Emerging Cybernetics Applications
r
intuitive feeling of how they interact with one another. To achieve this goal, the book g g
i
describes important networking standards, classifying their underlying technologies n
C
g
in a logical manner and gives detailed examples of successful applications.

The emergence of wireless access and dominance of the Ethernet in LAN y m
technologies has shifted the innovations in networking towards the physical layer and b
e m
characteristics of the medium. This book pays attention to the physical layer while
r
we provide fundamentals of information networking technologies which are used in n
u
e
wired and wireless networks designed for local and wide area operations. The book
t n
provides a comprehensive treatment of the wired IEEE802.3 Ethernet, and Internet ic i Switches, Routers Personal
as well as ITU cellular 2G-6G wireless networks, IEEE 802.11 for Wi-Fi, and IEEE s c BLE, ZigBee, UWB Ethernet, Wi-Fi 1-6G Cellular Local
802.15 for Bluetooth, ZigBee and ultra-wideband (UWB) technologies. The novelty A a Arch/PHY//MAC Arch/MAC/PHY Arch/MAC/PHY TCP/UDP/IP Metropolitan
of the book is that it places emphasis on physical communications issues related p t SONET/SDH

The “River Publishers Series in Communications” is a series of
comprehensiveacademicandprofessionalbookswhichfocusoncommunica-
tion and network systems. Topics range from the theory and use of
systems involving all terminals, computers, and information processors to
wired and wireless networks and network layouts, protocols, architectures,
and implementations. Also covered are developments stemming from new
market demands in systems, products, and technologies such as personal
communications services, multimedia systems, enterprise networks, and
opticalcommunications.
The series includes research monographs, edited volumes, handbooks
andtextbooks,providingprofessionals,researchers,educators,andadvanced
students in the field with an invaluable insight into the latest research and
developments.
