Passage: The Indian telecommunication industry is the world’s fastest growing industry with 811.59 million mobile phone subscribers as of March 2011. It is also the second largest telecommunication network in the world in terms of number of wireless connections. As the fastest growing telecommunications industry in the world, it is projected that India will have 1.159 billion mobile subscribers by 2013. Furthermore, projections by several leading global consultancies indicate that the total number of subscribers in India will exceed the total subscriber count for wireless connections in China by 2013.
The industry is expected to reach a size of 344,921 crore (US$76.57 billion) by 2012 at a growth rate of over 26 per cent, and generate employment opportunities for about 10 million people during the same period. According to analysts, the sector would create direct employment for 2.8 million people and for 7 million indirectly. In 2008-09 the overall telecom equipments revenue in India stood at 136,833 crore (US$30.38 billion) during the fiscal, as against 115,382 crore (US$25.61 billion) a year before. A large population, low telephony penetration levels, and a rise in consumer spending power have helped make India the fastest-growing telecom market in the world.
The market’s first operator was the state- owned Bharat Sanchar Nigam Limited (BSNL), created by corporatization of the Indian Telecommunication Service, a government unit formerly responsible for provision of telephony services. Subsequently, after the telecommunication policies were revised to allow private operators, companies such as Bharti Airtel, Reliance Communications, Tata lndicorn, Idea Cellular, Aircel and Loop Mobile have entered the market (Bharti Airtel currently being the largest telecom company in India). In the fiscal year 2008-09, rural India outpaced urban India in mobile growth rate. The total number of telephones in the country stands at 846.32 million, while the overall tele-density has increased to 70.89% as of March 31st, 2011. Mobile telephony experiences growths at rates such as 20.21 million subscribers a month, which were added in March 2011. Telecom in the real sense means the transfer of information between two distant points in space.
The popular meaning of telecom always involves electrical signals and as a result, people often exclude postal or any other raw telecommunication methods from its meaning. Therefore, the history of Indian telecom can be started with the introduction of telegraph. I ‘he Indian postal and telecom sectors saw a slow and uneasy start. In 1850, the first experimental electric telegraph line was started between Kolkata and Diamond Harbor. In 1851, it was opened for the use of the British East India Company.
The Posts and Telegraphs department occupied a small corner of the Public Works Department, at that time. Subsequently, the construction of 4,000 miles (6,400 km) of telegraph lines connecting Kolkata (then Calcutta) and Peshawbetween Kolkata and Diamond Harbor. In 1851, it was opened for the use of the British East India Company. The Posts and Telegraphs department occupied a small corner of the Public Works Department, at that time. Subsequently, the construction of 4,000 miles (6,400 km) of telegraph lines connecting Kolkata (then Calcutta) and Peshawar in the north along with Agra, Mumbai (then Bombay) through Sindwa Ghats, and Chennai (then Madras) in the south, as well as Ootacamund and Bangalore was started in November 1853. Dr. William O’Shaughnessy, who pioneered the telegraph and telephone in India, belonged to the Public Works Department, and worked towards the development of telecom throughout this period. A separate department was opened in 1854 when telegraph facilities were opened to the public.
In 1880, two telephone companies namely The Oriental Telephone Company Ltd. and The Anglo- Indian Telephone Company Ltd. approached the Government of India to establish telephone exchanges in India. The permission was refused on the grounds that the establishment of telephones was a Government monopoly and that the Government itself would undertake the work. In 1881, the Government later reversed its earlier decision and a license was granted to the Oriental Telephone Company Limited of England for opening telephone exchanges at Calcutta, Bombay, Madras and Ahmadabad and the first formal telephone service was established in the country. On 28th January 1882, Major E. Baring, Member of the Governor General of India’s Council declared open the Telephone Exchanges in Calcutta, Bombay and Madras. The exchange in Calcutta, named the “Central Exchange”, was opened at third floor of the building at 7, Council House Street, with a total of 93 subscribers. Later that year, Bombay also witnessed the opening of a telephone exchange.
