Airtel launched 4G services in India, becoming the first operator to do so. 4G provides broadband speeds of up to 100 Mbps for high quality audio/video streaming and fast data transfer. It will use TD-LTE technology initially through wireless dongles since few 4G devices are available in India yet. Airtel aims to expand 4G to major cities in multiple circles. While 4G growth is expected to transform India's digital economy, high infrastructure costs may limit initial deployment to urban areas. Airtel will face competition from Reliance Infotel and others also launching 4G services.
