Long Term Evolution (LTE) mobile technology or also known as the fourth generation of mobile networks (4G) , offers a wide range of improvements compared to all previous generations of the mobile phone network . This is how the 4G network has included in your system a communications channel dedicated to voice calls.
Therefore, with the use of all this LTE technology we can achieve a higher quality in each of the calls we make. This is how this technology has been initially created as a standard for the transmission of mobile data.
All this is known as VoLTE and its main objective is to provide the ability to use this service to manage voice calls . With this in mind, here we show you a little more about all this telephone service.

What are 4G calls and what is this technology for?
All this has become a improvement of the mobile network that gives its users a greater advance in what are the calls, thus offering a better sound quality, a faster call setup and the ability to navigate in 4G + at maximum speed , even if the device is in the course of a call.
This 4G service does not present any additional cost to its users. But it is simply a network improvement so that it can be enjoyed by everyone at the time of calling and using the corresponding data according to the plan of each telephone operator.
What are the main advantages and disadvantages of VoLTE?
Taking into account all of the above, we can see that this telephony service provides great advantages to each of its clients, allowing them to obtain greater benefits when using their mobile device >, especially when you want to communicate with third parties.
However, it is important to mention that this has also caused some inconveniences that are essential to keep in mind. According to this, here we present which are the main advantages and disadvantages of VoLTE.
Advantages
All this technology has been used mainly to provide greater comfort to users of mobile phones , where they have been able to count on a series of benefits that helps them improve your experience.
According to this, here are the main advantages that this offers:
High definition voice
It can be said that the main advantage of all this is to offer a high definition voice in each of the calls, this is how it is mainly responsible for improving the sound quality .
This new change that has been used, the services of calling other operators will go from having a 8 kbps codec to have up to a 13 kbps . To all this, you must add what are the compression improvements going from 300-3400 Hz to 50-7000 Hz.
Offers more battery savings
All of this technology will begin offering a new system that will provide each user with battery savings on their devices .
Faster connections
The call set-up time will be much faster , as will Internet browsing.
Last level communication service
Basically this will offer the possibility to switch between voice and video calls, as well as send images or location information through a GPS system .
Call by WiFi
Another of the great advantages that we can find with this whole system is to be able to call through a wireless connection . This translates into a data rate savings and a great help for those times when you do not have operator coverage or are outside the country .
Disadvantages
Given all the advantages that this offers, it is important to mention that there are also some problems that we must take into account and which we present below:
Limited service
So far, 4G technology is a bit lacking , although it is true, these networks each day have a greater extension, but today, they are still not very extensive . This is how even these types of networks are not found in all the Spanish territory , the same thing happening in the vast majority of countries.
Poor compatibility with telephone operators
Another drawback that can be found is that it still is not compatible with most telephone companies in the market . This has caused that VoLTE calls can only be made between users of the same operator.
Poor device compatibility
It is also important to mention that so far not all devices are compatible with this service, which means that many people cannot use it.
VoLTE vs VoWiFi vs VoIP Which is better and how are they different?
All of them are standards that by their names may seem very difficult to understand. However, it is quite the opposite, each one is very well specified about what function fulfills and is that they all have the same purpose and is to help improve call quality > and the user experience.
According to this, here we show you what are the differences of each of them and which is considered the best:
VoWiFi
VoWiFi is an open standard technology that offers a call realization via a wireless connection , without the need for have mobile coverage . This is how it allows the phone to redirect calls over a broadband connection.
The advantage of this whole system is that it allows to call and send SMS , where there are problems with coverage as in basements, under bridges, tunnels, raised floors , among others. All this is possible as long as there is a broadband connection.
VoIP
Also known as voice calls over IP, this service is based on SIP which is also known as the “Session Initiation Protocol” that uses a IP packet data service . This type of technology is used by platforms such as Skype.
Unlike other systems, in this case you don’t need to have a SIM card to be able to call, but you do need a IP connection that makes use of mobile data or WiFi to access web browsing.
VoLTE
As we know, VoLTE is a standard that allows you to call using an operator’s 4G network, where you can get better quality in the transmission audio. It is necessary to be on both phones, both the sender and receiver.
Currently , the VoWiFi network is considered the best among these three, having more access in those places where the coverage of the local operator does not arrive and more recognition before the most users.
Which operators in Spain offer Voice over LTE?
It is important to keep in mind that this technology will basically depend on the telephone operator , if it has been included in your system or not. Therefore, here we are going to mention which are the operators of Spain that have LTE . This will be essential to know when you want to buy a smartphone to use this technology.
For this we must acquire equipment from the following companies:
- Yoigo: It offers its customers this service thus presenting an update of its base stations to use part of its spectrum in 800 MHz for LTE .
- Orange: In the case of Orange, it has 800 MHz for the marketing of LTE, reserving part of its spectrum in 800 MHz where it also has 2.6 GHz.
- Movistar: According to all investments of this company, has been conditioning all its services in LTE to make it a 800 MHz band, in order to quickly extend the new networks > and thus obtain a greater reach.
- Vodafone: This company has happened just like Movistar , they have decided to take much of your investments in LTE so you can get access to new networks and get more reach for your users.
List of devices with support for 4G calls that you can buy
