Looking to shore up their businesses in the lead-up to the launch of disruptive newcomer Reliance Jio Infocomm (RJIL), Vodafone India, Bharti Airtel and Telenor India have all completed upgrades to their 4G networks, the Economic Times writes. The nation’s largest cellco by subscribers, Airtel, upgraded its 4G network in Mumbai to LTE-Advanced (LTE-A), enabling it to provide downlink speeds of up to 135Mbps. The upgrade utilises carrier aggregation (CA) technology to combine time division duplex (TDD) spectrum in the 2300MHz band with frequency division duplex (FDD) airwaves in the 1800MHz range.
Vodafone, meanwhile, has launched LTE services in Uttar Pradesh East and plans to inaugurate 4G networks in Gujarat and West Bengal by the end of the year. ‘Beginning with key business and residential corridors of Lucknow, we will soon expand our 4G services across the entire state in a phased manner,’ Vodafone’s head of business for the circle, Nipun Sharma explained, adding: ‘We invite our data savvy customers in [the circle] to make the most of the bonanza of special benefits being offered and enjoy the best mobile internet experience.’
Finally, for its part, Telenor has rolled out its 4G variant in Guntur and Rajahmundry and has launched a new series of 4G tariffs. The new plans start from INR85 (USD1.27) for 500MB of data with a 21-day validity and range up to INR249 per month for 2GB of data plus a lower per-minute rate of INR0.25 for domestic calls.
