Mukesh Ambani, on Wednesday, said to shareholders that Reliance was planning an investment of Rs. 70,000 crores in the telecoms business and would launch services in phases across India in 2015.

Reliance will launch its fourth generation (4G) mobile services in a phased manner this year.

Reliance Jio Infocomm Ltd is expected to use between 30,000 and 45,000 mobile towers when it starts offering 4G services.

Recently, the company entered into its sixth tower sharing pact with Ascend Telecom. Before that it signed similar deals with Bharti Airtel, Reliance Communications, Viom Towers and ATC India for using their tower infrastructures.

“The year 2015 will see the phased launch of Reliance Jio across India,” RIL Chairman Mukesh Ambani told the company’s shareholders at its 40th annual general meeting here in Mumbai.

The objective is to ensure that everything that we offer is future-proof and world-class,” Ambani added.

Reliance plans to invest more than Rs. 1, 80,000 crores over a three-year period that ends in March 2016 across all its businesses, Ambani said. Last year, the company had announced plans to invest 1.5 trillion rupees over three years.

The network and broadband services will be ubiquitous - initially covering all states, all the 5000 towns and cities accounting for over 90% of urban India and over 215,000 villages in India.

Eventually, the network will encompass each of our over 600,000 villages. All these efforts would help India become a leader in the digital era.
