As part of efforts to improve customer experience on its 4G network, Indian cellco Bharti Airtel has begun re-farming its 2G and 3G spectrum in areas where it holds liberalised airwaves. In an interview with the Economic Times, Airtel CTO Randeep Sekhon explained that the operator was close to finishing a project to implement former 2G spectrum in the 900MHz band on its 4G network across ten circles, and had begun to free-up 2100MHz band spectrum for the same purpose. In addition, the official said that Airtel has moved its core network to the cloud and is continuing to upgrade its transport network with fibre-optic cabling. Mr Sekhon went on to say that the company is also working more closely with application providers to ensure that their services work well on Airtel’s network.
In a related development, Vodafone Idea CTO Vishant Vora was quoted as saying that the company is deploying ‘future-proof’ Massive MIMO technology across its 4G network as it continues to integrate the networks of its predecessors, Vodafone India and Idea Cellular. The cellco is also cloudifying its core network, the official added.
