India's billionaire brothers -- Mukesh Ambani and Anil -- have inked a multi-million-dollar telecom deal to speed up the fourth-generation broadband services in this country, a move seen as a significant step in ending an eight-year-long bitter feud between them over their father's business empire.

Under the 2,200 U.S. dollars deal, announced Tuesday, separate telecom companies run by the two Ambani brothers would share networks to speed up 4G services. "Mukesh -- also India's richest man -- would use his brother Anil-owned Reliance Communications company's optic fiber infrastructure for the launch of his telecom business," sources said.

Anil-owned Reliance Communications and Mukesh-owned Reliance Jio Infocomm Ltd plan to share telecommunications towers in the future, the brothers' two companies said in two separate statements.

Three years after their father Dhirubhai Ambani died in 2002 without leaving a will, his Reliance empire was divided between the two brothers following a bitter seven-month feud.

While 55-year-old Mukesh acquired petrochemicals, refinery, and oil and gas businesses, his younger brother Anil got telecom, power and financial services. The two brothers had fought bruising court battles in the past over natural gas.
