4G LTE – Voice over Long Term Evolution

Hi guys, today I’m going to discuss about some essential communication technology terms such as 4G LTE, VoLTE, HD Voice and video conferencing. What it really stands for and what are the advantages and disadvantages…?


Long Term Evolution

Long Term Evolution is fourth generation mobile technology.  LTE is the fastest data transfer technology which has high downloading and uploading speed. It requires fractions of seconds to connect to the network.


Voice over Long Term Evolution

Voice over Long Term Evolution is a technology for speedy wireless communication and data over 4G Long Term Evolution (LTE) networks. When a user make a call from VoLTE supported phone voice information can be carried over a higher bandwidth pipe resulting in superior call quality, faster call connectivity and the ability to perform multitask without interrupting data speed and keep on to use 4G data services, such as web browsing and tethering, during call.

4G means fourth generation

Benefits of VoLTE
  • Better call quality – The biggest benefit is that VoLTE supports better quality calls (HD calls).
  • Better connectivity – VoLTE can connect calls more rapidly than a usual GSM or CDMA call. Calls can connect in about a second or two, vs. the three or more seconds.
  • Improved battery life – VoLTE minimize switching to the different networks (i.e. 4G to 3G or 2G).Since less use of battery.
  • Video calling – Using VoLTE technology at both the terminals can connect to a video call.
  • Lower VoLTE CostsVoLTE technology is not much expensive.  
Difference between LTE and VoLTE

VoLTE: VoLTE or voice over LTE means you can simultaneously send voice and data over the network without interrupting data speed and lowering the quality of voice.

LTE: Where as in LTE the quality of voice reduces if data connection is kept on.

HD Voice: What Does HD Mean?
HD Voice 
High Definition Voice

HD Voice is a technology that extends the frequency range of audio signals transmitted over telephone lines, resulting in more natural sounding calls.

HD Voice provides superior voice call.  It reduces background noise and you will be able to differentiate between ‘s’ and ‘f’ easily.

To use HD Voice:
  • A HD Voice compatible mobile phone at both caller and receiver ends.
  • Both caller and receiver mobile phones need to be connected to HD capable base station.
Benefits of HD Voice
  • Decline of weariness
  • Less robotic and more clarity
  • More precise notations
  • Better conference calls
Video conferencing

A Video conferencing is a live, video communication over a network or internet between the participants residing in separate locations .It improves conversation and brings people close together by allowing seeing each other.

Pros and cons of Video conferencing


  1. No time restriction: Video conferencing can be conducted at any time of the day.No specific time required for Video conferencing.
