The French word télécommunication was coined in 1904 by the French
engineer and novelist Édouard Estaunié
The word telecommunication was adapted from the French word
compound of the Greek prefix tele-, meaning "far off", and the Latin
communicare, meaning "to share".
In 1792, Claude Chappe, a French
engineer, built the first fixed
visual telegraphy system (or
semaphore line) between Lille
and Paris. However semaphore
systems suffered from the need
for skilled operators and the
expensive towers at intervals of
ten to thirty kilometers . As a
result of competition from the
electrical telegraph, the last
commercial semaphore line was
abandoned in 1880.

HISTORY OF TELECOMMUNICATION
The first commercial electrical telegraph was constructed by Sir Charles
Wheatstone and SirWilliam Fothergill Cooke, and its use began on April 9, 1839.
Then many transformation and improvement were done in telegraphics.
The conventional telephone now in use worldwide was first patented by
Alexander Graham Bell in March 1876.As with other great inventions such as
radio, television, the light bulb, and the digital computer,
Alexander Graham Bell and Gardiner Greene Hubbard, who created the first
telephone company, the BellTelephone Company of the United States, which
later evolved into AmericanTelephone &Telegraph (AT&T).
The first commercial telephone services were set up in 1878 and 1879 on both
sides of the Atlantic in the cities of New Haven, Connecticut, and London,

Value Added Services Market
India's runaway success in mobile telephony
has also given a boost to the mobile value
added services (MVAS) market. According to
a study by Stanford University and consulting
firm BDA, the Indian MVAS is likely to grow at
a CAGR of 44 per cent 2010.
The Government has taken many proactive initiatives which has

be from rural areas.
The Indian telecom industry's revenue, likewise, is estimated to
increase, which according to Ernst &Young is expected to be 3.6 per

Private sector is estimated to continue its dominant share, accounting
for 67 per cent of the total projected investment while public sector

Reasons for growth
> low tariffs
>falling handset prices
The bottlenecks for ' IndianTelecom Industry ' are:
>Slow reform process.
>Service providers bears huge initial cost to make inroads and
achieving break-even is difficult.
>Lack of infrastructure in semi-rural and rural areas, which
makes it difficult to make inroads into this market segment
as service providers have to incur a huge initial fixed cost.
>Huge initial investments.
>Limited spectrum availability and interconnection charges
between the private and state operators.
Rural Telecom Market – an
According to numbers compiled by theTelecom Regulatory
Authority of India As on September 2007, out of the
209 million mobile users in the entire country, 43
million were in rural areas.
Rural India will wrest 40 percent of new telecom
India’s rural telecom connectivity is poised for
explosive growth in the next five to 10 years,
grabbing a 40 percent share of the new market
The government will roll out new incentives for
mobile networks in rural India.
It’s also planned that the ultra-low cost handset of
approximately Rs.840 ($20) to the market with
built-in subsidies, lifetime validity and minimal
maintenance costs have promoted mobile usage in
Reasons for rural inclination
rural areas has now become the hot spot for private telecom operators.
Nearly 75 per cent of the mobile users in the villages are now owned by private
operators as cellular phones catch the imagination of rural consumers. Until
now, state-owned Bharat Sanchar Nigam Ltd was known to be the only
significant rural telecom operator in the country.
Analysts said that the share of rural telecom consumers will continue to increase
as operators have initiated an aggressive roll-out plan to cover remote areas of
the country.This is primarily driven by a slump in the growth rate of mobile user
base in the metro and urban areas.
According to the data released by the Cellular OperatorsAssociation of India
Circle C and Circle B States such as Bihar, Kerala, Madhya Pradesh and Punjab
are showing better growth rates compared to the metros.Therefore, most of the
mobile operators are investing heavily in setting up infrastructure in these
The telecom regulator has suggested a number of initiatives to make mobile
connection attractive, including lower entry cost to make it more affordable.

Bharti Airtel is one of the most valued company of India. It is also the leading
telecom provider in India. Reliance Communications follows Airtel in market
capitalization. Interestingly the same order holds good for the total number of
subscribers these telecom companies has.
Bharti has a subscriber base of 91.1 million and added 2.7 million subscribers in
Feb 2009. Reliance added 3.3 million new subscribers in FEB 2009 to take the
total to 69.6 million. Reliance rolled out its GSM operations late last year
following which there was a surge in the number of new subscribers. It also
added more subscribers than Airtel in a month.
Following MTNL is the list of other telecom providers in infrastructure,
equipment and value added services. Vodafone-Essar which has 66 million
subscribers is not listed on the Indian Bourses.
BSNL is also not listed and that is the reason why it is not in the list. If listed it
could be one of the top companies.There is a lot of things happening around
BSNL’s IPO even before the recession started. Now, that the recession has
started the IPO plans were postponed. But, BSNL will dilute 10% stake sooner
