With billions of ‘people and things’ becoming increasingly connected, the need to combine the potential
of unlicensed and licensed wireless services has become an imperative for the operators, cities, high
density venues and players focused on key market opportunities such as IoT, big data and 5G. The WBA
has developed Vision 2020 to harness its experience of creating seamlessly interconnected wireless
services in new and emerging areas.
Cognitive radio has emerged as a promising technology for maximizing the utiliza-
tion of the limited radio bandwidth while accommodating the increasing amount of
services and applications in wireless networks. A cognitive radio (CR) transceiver
is able to adapt to the dynamic radio environment and the network parameters to
maximize the utilization of the limited radio resources while providing flexibility in
wireless access. The key features of a CR transceiver are awareness of the radio envi-
ronment (in terms of spectrum usage, power spectral density of transmitted/received
signals, wireless protocol signaling) and intelligence.
Recent advances in wireless communication technologies have had a transforma-
tive impact on society and have directly contributed to several economic and social
aspects of daily life. Increasingly, the untethered exchange of information between
devices is becoming a prime requirement for further progress, which is placing an
ever greater demand on wireless bandwidth. The ultra wideband (UWB) system
marks a major milestone in this progress. Since 2002, when the FCC allowed the
unlicensed use of low-power, UWB radio signals in the 3.1–10.6GHz frequency
band, there has been significant synergistic advance in this technology at the cir-
cuits, architectural and communication systems levels. This technology allows for
devices to communicate wirelessly, while coexisting with other users by ensuring
that its power density is sufficiently low so that it is perceived as noise to other
users.
The goal of this book is to introduce the simulation methods necessary to describe
the behaviour of semiconductor devices during an electrostatic discharge (ESD).
The challenge of this task is the correct description of semiconductor devices under
very high current density and high temperature transients. As it stands, the book
can be no more than a snapshot and a summary of the research in this field
during the past few years. The authors hope that the book will provide the basis
for further development of simulation methods at this current frontier of device
physics.
The planarization technology of Chemical-Mechanical-Polishing (CMP), used for the manufacturing of multi-
level metal interconnects for high-density Integrated Circuits (IC), is also readily adaptable as an enabling technology
in MicroElectroMechanical Systems (MEMS) fabrication, particularly polysilicon surface micromachining. CMP not
only eases the design and manufacturability of MEMS devices by eliminating several photolithographic and film
issues generated by severe topography, but also enables far greater flexibility with process complexity and associated
designs. T
Commercial energy storage has moved from the margins to the mainstream as it
fosters flexibility in our smarter, increasingly integrated energy systems. The
energy density, availability, and relatively clean fossil profile of natural gas ensure
its critical role as a fuel for heating and electricity generation. As a transportation
fuel, natural gas continues to increase its market penetration; much of this has been
enabled by emerging developments in storage technology.
