| A
Network system serves the important
function of establishing a cohesive
architecture that allows a variety
of equipments to transfer information
in a near-seamless fashion. While
the precise structure of the future
Internet is not yet clear, many
directions of growth seem apparent.
One is the increased availability
of wireless access.
Wireless servicess enable applications
not previously possible in any economic
fashion. For example, global positioning
systems (GPS) combined with wireless
internet access would help mobile
users to locate alternate routes,
generate precise accident reports
and initiate recovery services,
and improve traffic management and
congestion control. In addition
to wireless laptop computers and
personal digital assistants (PDAs),
wearable devices with voice input
and special display glasses are
under deployment.
