What VoLTE Means? This One will Definitely Help You Know: Now in this 4G Generation, we have become habitual of using higher speeds of networks. Each & every user is willing to have the fastest as well as the best data carrier for browsing and downloading. And in this tough fight, we have been introduced with a new technology that most of us are already using but many of us still can’t figure it out properly. To make you all understand the technology which you have been using for communication through mobile phones which have up to 3 times more voice & data capacity than 3G UMTS & also 6 times more than 2G GSM. So without getting much-delayed state get started with the in-depth of VoLTE now.

What VoLTE Means? This One will Definitely Help You Know:

VoLTE basically stands for Voice over Long-Term Evolution. That is based on the IP Multimedia Subsystem (IMS) i.e. an architectural framework that provides standards for delivering voice or other multimedia services over IP (like Skype). As the name suggested, Voice over LTE happens when a particular carrier allows placing a phone call over LTE connection instead of the more common voice networks.

The dependency on the circuit switched voice network is no more a requirement to be maintained. So using VoLTE you will not face any problems like in Verizon phones which were not able to use voice & data simultaneously. AT & T and T-Mobile also relied on the combination of LTE for data & HSPA+ for calls, that dropped down to 3G signals while taking voice calls on the other line. Through VoLTE you are able to use more bandwidth for high-quality audio transmission during  phone calls.

If you are using VoLTE and doing a voice call with someone using VoLTE, the immediate difference in the quality of the call is observed on both ends.

Voice Quality over VoLTE:

So when summarizing we will have to say that VoLTE or voice over LTE simply means that your voice quality won’t reduce even if your data is turned on while making and receiving a call. Over VoLTE the call quality is superior to that of 3G or 2G connections also more data transmission can happen over 4G than 2G or 3G. Up to three times as much data as 3G and up to six times as much as 2G to be precise, making it easier to make out not only what the person on the other end of the line is saying, but also their tone of voice. Essentially it’s an HD voice call and it’s a much richer experience overall.
