After winning the licence to offer 4G network in 2010, Reliance Industries Ltd. (RIL) is now planning to invest $10 billion to start its 4G network across the country.
Reliance will soon launch LTE (Long Term Evolution) network which is the faster version of the mobile Internet to offer services similar to Skype video and voice calling services (VVoIP) to its subscribers.
Infotel Broadband, has developed VoLTE (Voice-over-LTE) which will enable voice call services on its wireless broadband network. But currently the quantity of mobile devices models supporting VoLTE is extremely small. LTE phones and tablets mainly support only data transmission over an LTE modem, while voice and video are going via 2G/3G network.
