"Under the terms of the agreement, Reliance Jio Infocomm will utilise up to 45,000 ground and rooftop-based towers across Reliance Communication's nationwide network for accelerated roll-out of its state-of-the-art 4G services," a company statement said.
"The agreement provides for joint working arrangements to configure the scope of additional towers to be built at new locations to ensure deep penetration and seamless delivery of next generation services."
This accord follows the inter-city optic fiber sharing agreement already signed in April as part of a comprehensive framework of business co-operation between Mukesh Ambani-led Reliance Jio Infocomm and Anil Ambani-led Reliance Communications.
