Difference Between LTE and VoLTE in 4G Spectrum

So, by the end of 2016 everyone is well aware of terms LTE and VoLTE which can be seen mobile devices under 4G spectrum.
As Reliance Jio in India brought  a massive change in providing 4G for free with unlimited plans and gained lots of customers over 50 million people

Now coming to terms
 LTE    means Long Term Evolution and
VoLTE  means  Voice Over Long Term Evolution

Basically VoLTE is an update for LTE . Using VoLTE we can make calls over LTE network.
So, the trick over here is our voice when we call others is converted into data and can be charged according to the data utilized and the voice clarity over LTE network is much clear and smoother when compared to 3G and 2G Spectrums

By this you can say VoLTE is a software utilized over 4G to convert our voice into data. During the times there can updates provided to this software like presently people are getting updates in name of VoLTE HD  which means Hi-Definition   in voice clarity in our phone calls  over LTE

Now LTE means generally 4G like under 3G we have UMTS and under 2G we have GSM networks so by this LTE is a network where 4G is provided to our mobile phones

What are the benefits of VoLTE?

Superior call quality – The big advantage of VoLTE is that call quality is superior to 3G or 2G connections as far more data can be transferred 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 over all.

Improved coverage and connectivity – VoLTE can connect calls up to twice as fast as the current methods and as 2G and 3G connections will still be available when there’s no 4G signal it simply means that there’s greater mobile coverage overall, as currently places with a 4G signal but no 2G or 3G means that one you can’t make or receive calls.

You might think that would be a rare occurrence, but some of the frequencies that 4G operates on, such as the 800MHz spectrum, have far greater reach than 2G or 3G spectrum, so you’ll be able to get signal further away from a mast or in buildings which other signals struggle to penetrate. Indeed, Three is fully relying on its 800MHz spectrum for VoLTE calls.

However, while 2G and 3G services would likely remain they wouldn’t be as necessary as they are now and much of the spectrum used for 2G in particular could potentially be repurposed to increase capacity on 4G networks.

Better battery life –
 Anyone who currently uses 4G could also find their battery life increased with VoLTE, as right now whenever you make or receive a call your phone has to switch from 4G to 2G or 3G, since 4G calls aren’t supported (other than on Three Super-Voice) and then once the call is finished it switches back again. All that switching, plus the need to search for a different signal each time, can give the battery a significant hit.

Video calling –
 It’s also theoretically possible to make video calls over 4G, much like a Skype call 
except you’d just use your mobile number and be able to use the regular dialler and call interface, so you can make and receive video calls from anyone else with VoLTE, rather than relying on separate accounts.

In fact you may have noticed that Skype and other existing video calls services often seem to have superior audio quality to voice calls. That’s because like VoLTE they use more data as part of a similarly named VoIP system, so you can expect your voice calls to start sounding more like Skype calls, but they won’t hit your battery life as much as Skype does.

Not only could video calls become native to the dialler, but other Rich Communication Services (or RCS’s) could as well, such as file transferring, real time language translation and video voicemail and there may be applications which haven’t even been thought up yet.

As VoLTE is tied to data it could also mean that you won’t have to worry about how many minutes you use, as everything will fall under data use.

Limitations of VoLTE:
The problem with Voice over LTE is that 4G LTE is a data-only networking technology, so it doesn’t natively support voice calls. While 3G and 2G were primarily designed with voice calls in mind and data was added to them.
The data charges are costly and datapack can be completed faster when we are over 4G .
