F. SMITH (1974) says that communication is of course “ when you know
something which you want someone elae to know you tell them,” and that is a special
form of communication. The Ancient Greek word “Tele” means “FAR” OR “distance”,
hence the word: telecommunication simple means literally “Distance or Far
communication.”
There are many ways or means of information sharing the (i.e.).
Communication) which include among others
the following; Radio waves, telegraphic telephone computers, the internet but the one we are concerned with in this study is
telephony using (GSM
HANDSET.). Mob lie handset is a means by
which message are sent and received in spoken from using the principle of
modulation- demodulation.
According
to KENNEDY G (199 3), He said that was
first patented by Alexander Graham Bell master patent of the telephone from
which all other patents for electric telephone devices and features flowed.
Telecommunication
has a significant social, cultural and economic
impact on modern society. In 2008, estimates place the telecom industry’s
revenue at 53.8 5 trillion or just under
3 percent of the Gross World product (official
exchange rate).
EDWARD LENER (1 994) says,
economic impact of telecoms is discussed under “microeconomics and macroeconomics” On the former, companies have
used telecoms to build global business empires while on the later, there is a link between telecoms
and economic growth
