New Delhi: Aiming to enhance indoor network experience for Airtel 4G smartphone customers, telecom major Bharti Airtel on Monday announced it has upgraded its mobile network in Delhi-NCR with the deployment of LTE 900 technology on the 900 Mhz spectrum.
"As we introduce LTE-900, we will further step up our indoor network coverage. It will enable high speed connectivity and HD quality VoLTE calling for our customers in Delhi," Vani Venkatesh, CEO-Delhi-NCR, Bharti Airtel, said in a statement.
Given the high propagation and reach of the 900 Mhz spectrum, it would result in wider availability of 4G network across Delhi NCR -- one of the largest and most dense telecom markets in the country.
As part of its network transformation programme, the telecom major has been deploying network technologies such as pre-5G Massive MIMO and Carrier Aggregation to enhance network capacity over existing spectrum.
The firm uses a mix of 2,300 Mhz, 1,800 Mhz, 2,100 Mhz and 900 Mhz spectrum bands to deliver network experience to its users.
