Vodafone is finally ready to launch its 4G VoLTE service in India from January 2018. The VoLTE service will initially launch in Mumbai, Gujarat, Delhi, Karnataka, and Kolkata, and will be extended across the country shortly after, the telecom operator said.
Vodafone will be the third operator after Reliance Jio and Airtel to offer 4G VoLTE in the country.
It is claimed that the cost of providing voice calls under the 4G VoLTE technology is considerably cheaper than traditional networks like 2G or 3G.

VoLTE, as the name suggests, transmits voice calls over a data network. Calls are chopped into packets just like how GPRS (general packet radio service) or internet data is transmitted.
This results in higher quality calls, as there is very little transmission loss (hence, lower call costs). That’s why some operators call this HD voice quality. While telecos claim high data speeds for 4G VoLTE network, it’s quite evident that the technology is more suited to make voice calling better and cheaper.

4G VoLTE uses the 800 MHz, 1,800 MHz and 2,300 MHz bands of spectrum. But unlike voice networks, which have to block off one band to make a call go through and channel data across another band, VoLTE can send both voice and data over the same band simultaneously.

This allows for quicker call connectivity. Also, these bands can reach further than traditional voice networks, hence better coverage. They can also be paired with WiFi networks easily.
