Wireless Local
Networks -- a
Revolution in
Local Access introduces
and thoroughly
develops the key
technical concepts
and initiatives
that are driving
the global revolution
in mobile computing
services. Vital
elements of this
subject include
understanding
the challenges
of effectively
transporting data
over the wireless
medium, and adapting
Internet service
to this medium.
This course covers
the core enabling
technologies that
make delivery
of data services
over mobile systems
practical and
secure, and explores
the exciting developments
that are coming
to define the
emerging wireless
telecommunications
infrastructure.
The convergence
of wireless communications
and Internet technology
is creating remarkable
opportunities
for innovation.
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
covers the essential
elements of this
emerging discipline,
and develops an
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.
Many of the details
of just how the
mainstream of
Internet technology
will be adapted
to the mobile
environment are
still in process
of getting sorted
out. Regardless
of these outcomes,
it is certain
that initiatives
with Wireless
LANs, Third Generation
Mobile/Cellular,
and Mobile IP
are important
developments in
this area.
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.
Each delegate
is provided with
a permanent, comprehensive
workbook which
is much more than
a set of lecture
notes. In addition
to being a workbook
designed to track
with the lecture
portion of the
program, it is
designed with
features that
give it real value
as a permanent
reference book.
These include:
• All text
is presented in
the form of complete
fully descriptive
sentences, designed
to be a highly
readable, long-term
valuable reference
on the job.
• A text-book
style Subject
Index and a comprehensive
Table of Contents,
consistent with
effective reference
access to content
details.
• A thorough,
highly readable
subject-specific
glossary which
provides detailed
descriptive treatment
of key items of
terminology.
