Reliance Jio has already rolled out 4G services for its employees, and will soon be launching its LYF branded smartphones as well. In addition to being 4G LTE capable, the highlights of these upcoming smartphones are connectivity options like VoLTE [Voice over LTE] and VoWiFi [Voice over WLAN].
VoLTE is one of the features we are looking forward to on the soon-to-be-launched smartphones in India. VoLTE essentially lets Jio handle cellular voice calls over LTE networks, which results in HD voice clarity, faster call connectivity among others.
To give an idea of how good it really is, we have got our hands on a demo video comparing voice quality on VoLTE and GSM.
As you can hear, there is a world of a difference between HD voice calls and GSM voice calls. In the first instance, the woman’s voice is barely audible over the background noise, and the quality isn’t great either. In the second instance, there is hardly any background interference, and the woman’s voice is crystal clear.
Originally LTE was only meant to carry data, and operators would revert to 2G or 3G networks to carry voice. Now operators can transmit audio calls at much higher frequencies, and in comparison to a standard call, HD voice calls also takes in more audio samples per second. In other words, more details are heard clearly during a call.
Apart from Reliance Jio’s upcoming LYF branded smartphones, RIL’s partners like LG, and Micromax too will be launching smartphones that will support VoLTE. Earlier today, Lava launched the V5, which is a Rs 11,499 smartphone with 4G LTE and VoLTE support.
