Mobile Computing
and The Wireless
Internet provides
an introduction
to the technical
concepts and developments
that are driving
the global revolution
in mobile services.
Vital elements
of this subject
include the challenge
of effectively
transporting data
over the wireless
medium, and adapting
Internet service
to this medium.
This course introduces
the core enabling
technologies that
make delivery
of data services
over mobile systems
practical, and
explores the exciting
developments that
are defining the
emerging wireless
telecommunications
infrastructure.
The convergence
of wireless communications
and Internet technology
is creating remarkable
opportunities
for innovation
in applications
development. The
remarkable changes
that are happening
in each of these
two fields is
noteworthy, but
in combination,
the momentum that
these topics are
generating in
the industry is
truly exciting.
This short course
introduces the
essential elements
that define this
emerging discipline,
and lays the groundwork
of understanding
of how these component
parts contribute
to vital new systems
solutions.
The unprecedented
growth and pace
of innovation
in the Internet
and its related
family of protocols
and applications
is now having
a major impact
on the mix of
technologies that
are part of the
emergent mobile
computing developments.
Just how the mainstream
of Internet technology
will be adapted
to the mobile
environment is
still not completely
settled, although
initiatives with
Wireless LANs,
Third Generation
Mobile/Cellular,
and Mobile IP
are important
developments in
this area.
The course is
intended to provide
a balanced view
of both local
and wide area
wireless data
networking developments.
Just as with wired
networks, this
scope covers both
the privately
owned and managed
local networks
and the shared
wide-area infrastructure
supported by public
network providers.
The objectives
of this course
are:
• To provide
an effective,
up-to-date training
experience that
integrates the
essential elements
of this broad
and quickly developing
field.
• To offer
participants an
opportunity to
appreciate the
principles and
embedded technologies
that contribute
to delivering
data services
in a wireless,
mobile environment.
• To interpret
and present a
rationalized view
of emerging initiatives
in wireless networking.
This short course
is designed to
appeal to, and
offer effective,
highly usable
knowledge to professionals
that are affected
by mobile/wireless
data technology.
This includes
IT specialists,
engineers, managers,
planners and developers.
This course is
intended to appeal
to a range of
backgrounds, ranging
from junior/intermediate
people needing
a more comprehensive
knowledge base,
to specialists
in one or more
of the embedded
disciplines who
wish to broaden
their professional
skills.
The first sections
of this short
course provide
a review the various
technologies that
contribute to
the current trends
in mobile data
usage, with particular
emphasis on cellular/mobile
and Wireless LAN
technologies.
Wireless LAN
technology, in
particular is
a dynamic, growing
class of service
that is finding
its way into many
applications.
This short course
introduces a number
of issues, technologies
and solutions
that bear on this
exciting topic.
