L900 is an advanced technology that aims at providing a stronger 4G indoor coverage experience for users, with superior calling and faster data speeds, Vi said in a statement.
This is part of Vi's broader strategy to upgrade its network infrastructure, following a successful ₹18,000 crore Follow-on Public Offering (FPO).
Vi has also acquired additional spectrum in the recently concluded spectrum auction, committing ₹31 crore for 0.4Mhz of spectrum in the 900 Mhz band in Kolkata Circle and ₹376 crore for 7.6 Mhz of spectrum in the 900 Mhz band in West Bengal Circle.
With these, Vi now has a total spectrum portfolio of 334.4Mhz in Kolkata and 536.8Mhz in West Bengal circles.
The company is deploying this technology in other cities of the country.
The stronger network will help operators to not only retain but grow its customer base, a market analyst said.
