This short course
offers a thorough
introduction to
the technical
concepts and developments
that are driving
the global revolution
in wireless/mobile
services. Key
parts of this
subject include
the features of
protocols that
have been developed
to assure successful
communication
over the wireless
medium, and limitations
to the way Internet
service is delivered
with this emerging
class of service.
This course covers
the core enabling
technologies that
make data over
mobile systems
feasible, and
explores the exciting
developments that
are leading the
wireless revolution.
Wireless and Internet
technologies are
converging, creating
remarkable opportunities
for innovation
in applications
development. The
changes that are
happening in each
of these two fields
are important,
but in combination,
the momentum being
generated in the
industry is truly
exciting. This
short course introduces
the essential
elements that
define this emerging
subject, and lays
the groundwork
for understanding
how these topics
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 the driving
force behind most
of the development
in mobile computing.
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,
Location-Aware
Services and Mobile
IP will undoubtedly
be important parts
of this picture.
The course provides
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.
- To demonstrate
WLAN system
design, configuration,
testing issues
and procedures.
- To show some
of the unique
applications
made possible
with mobile
and location-aware
technologies
in IT, non-traditional
and recreational
applications.
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, administrators
and developers.
It will appeal
to a range of
backgrounds, from
junior and intermediate
people needing
a more comprehensive
knowledge base,
to specialists
in one or more
of the related
disciplines who
wish to broaden
their professional
skills.
