Advanced Technology - About This Section
This section will allow you to explore some of the advanced topics in telecommunications
as well as some of the lastest technologies.
GPS - Global Positioning System
How often have you gotten lost on a road trip, or tried to guess what kind of weather was
headed your way. Well, a fairly new technology called GPS has made it possible to tackle
some of lifes most ancient problems.
Internet in the Sky
A new company called Teledesic is in the middle of developing an amazing technology that
would take near impossible Internet tasks, and turn them into everyday solutions. Through
use of Low-earth-orbit-satellites, Teledesic aims to create an end to end technology that
would meet the high broadband demands of businesses, schools, and individuals.
ISDN - Integrated Digital Service Network
ISDN, Integrated Services Digital Network, is a set of CCIT/ITU standards for digital
transmission over ordinary telephone copper wire or other media. Users who install ISDN
adapters in place of their modems can see graphics and other information loading very
quickly up to 128-Kbps.
DSL - Digital Subscriber Line
DSL is a technology capable of providing high bandwidth-information to individuals and
business users by means of ordinary copper telephone lines. DSL installations began in
1997 and have since become increasingly popular with customers desiring a fairly
inexpensive and fast connection.
ATM - Asnycronous Transfer Mode
Most of us usually think of ATM as the automated teller machine that bank customers use to
make transactions without a human teller. However, in the context of telecommunications,
ATM stands for asynchronous transfer mode.
SONET - Synchronous Optical Network
In 1984 the cetral research group at Bell Communications Inc., jointly owned at the time
by the Regional Bell Operating Companies, introduced SONET. SONET is the U.S. standard of
synchronous data transmission.
Wireless refers to a communications system in which waves carry a signal through air
rather than through a wire. Most wireless systems use radio frequency (RF) or infrared
