Chennai, Oct. 3 “India is happening” and with “almost five-six million subscribers added every month, the country is witnessing exciting times in the telecom industry,” beamed Mr Srinivasa Rao Saripalli, Circle Operating Officer, Tamil Nadu region, Tata Teleservices Ltd.

He was addressing nearly 350 students of Madha Engineering College belonging to the MCA and Electronics and Communications streams, under the aegis of the Business Line Club.

Speaking on Mobile Technology, Mr Rao traced its evolution, discussed the working of the CDMA (Code Division Multiple Access) technology and threw light on its applications, current trends and its future.

From the traditional “wire-at-home” network, the concept of telephone has come a long way “to being connected on the move”, Mr Rao said.

He explained that CDMA technology ensures confidentiality of the information shared and minimises errors and information loss.

Enumerating its benefits, he said CDMA provides improved privacy, voice quality, longer battery life and supports simultaneous voice and data control. Interestingly, CDMA is a technology that has its roots in Defence, where it was first used, before it started being utilised for commercial purposes in 1993. In India, it was adopted in 1999.

“CDMA has grown to a level of enhanced data application,” Mr Rao said, progressing from the first-generation plain-vanilla voice communication using analogue air interface to the current 2.5 generation, which enables voice and improved data rates transfer.

Increasingly, entertainment is also becoming a popular feature and moving forward, “we will be in an era where voice, data and entertainment will converge onto a handheld device,” he mentioned.

Mr Rao stated, “CDMA is a technology that has gone beyond voice” and today finds application in the fields of education, healthcare, public safety and economic development, among others. Answering questions from students, he said mobile technology could also play a pivotal role in identifying anti-social elements by narrowing down on area of their operation by using ‘cell sites’.

Mr Rao said even GSM operators will have to eventually adopt WCDMA (Wideband Code Division Multiple Access), a next-generation technology, in order to upgrade.

Interspersing his presentation with humour and applications of mobile technology in everyday life, he confessed, “I have to carry my watch and the mobile phone. I even keep it under my pillow when I go to sleep. In the corporate world, you can never say you are not reachable.”

Mr N. Krishnan, Regional General Manager, The Hindu, emphasised the need to be up to date with current information and trends in order to do well academically. Dr R. Venkatasamy, Principal, Madha Engineering College, also launched the college’s Web site during the event.
