Network and communications provider Cisco expects mobile data traffic in India to increase 114-fold by 2015, and consumers to download or stream more than 629 hours of video every second on broadband, the company said on Thursday as it shared its global visual networking index forecast.

The explosive growth will occur due to proliferation of tablets, mobile phones and connected appliances, larger number of internet users, faster broadband speeds and more content on video.

According to estimates of the report that charts internet growth and trends, Indian mobile data traffic will augment at a compound annual growth rate of 158%, the company revealed. Cisco anticipates that by 2015 mobile data in the Indian market will be 15 times the volume of the entire Indian Internet in 2010.

Mobile data traffic will ride on the estimated spurt in the number of devices and higher connection speeds. According to Cisco''s forecast, India will have more than 1 billion networked devices in four years from now, compared to 570 million in 2010.

The estimate includes mobile phones and tablets and other machine-to-machine connected devices. Globally, Cisco anticipates the total number of connected devices to be nearly 15 billion, more than double of the world's population.

"Growth in Internet data traffic, especially video, creates an opportunity in the years ahead for optimizing and monetising visual, virtual and mobile Internet experiences. As architect of the next-generation Internet, Cisco stands ready to help our customers," said Cisco's vice president of worldwide service provider marketing Suraj Shetty .

Cisco also predicts the average mobile connection speed to grow 56-fold, reaching 1,037 kbps in four years. Globally, mobile Internet data traffic will increase 26 times from 2010 to 2015 while the study indicates Asia-Pacific region taking the top spot from North America by 2015 for generating the most traffic on Internet.

Despite a dismal broadband penetration of a little over 10 million customers, the company forecasts more number of Indians to use the Internet. Traffic over Internet is expected to jump nine-fold by 2015.
