Voice over Long-Term Evolution (VoLTE)  & VoWiFi

 

VoWi-Fi stands for Voice over (EPC-integrated) Wi-Fi. VoWi-Fi is a complementary technology to VoLTE and utilises IMS technology to provide a packet voice service delivered over IP via a Wi-Fi network. Where possible, VoLTE calls may be seamlessly handed over between LTE and Wi-Fi and vice versa. Conversational video is also possible via Wi-Fi.
 

Differences Between VoIP and VoLTE

 

Meaning: VoIP means ‘Voice over Internet Protocol’ whereas, VoLTE stands for ‘Voice over LTE network’.

Technology: The major difference between VoIP and VoLTE is based on the technology they both use. VoIP uses a web-based network such as 3G, Wi-Fi or ADSL to transfer voice data. These modes of transfer of data are commonly used as they are easy to access. VoIP is very common among smartphones and computers, however; there are a few barriers which users have to face. Whereas, VoLTE is using LTE network technology such as 4G for transferring voice data from one place to another. It has a faster bandwidth and speed which helps to attract more people in using this network. Due to the efficiency of VoLTE, it is preferred over VoIP. Most modern smartphones are supporting VoLTE technology for transferring voice data.

Network: VoIP is using networks such as 2G and 3G whereas, VoLTE is using 4G for transferring voice data.

Establishment: VoIP was introduced in the 1990’s and had immense popularity as it helped people in transferring voice messages from one place to another without any problem, however, there were a few hurdles due to the lack of internet range whereas, VoLTE was established in 2000’s and since then it has been improved in many ways to help people communicate with each other without having to face any hurdles.

Connectivity: VoIP is supported by web and VoIP phones whereas; VoLTE is supported by the modern smartphones. As compared to VoIP, VoLTE has a higher bandwidth and it offers a better quality. VoLTE sends high definition voice data from one place to another however, VoIP sends the packets of data which is the actual voice digitized in the form of data through the internet from the sender to the receiver. These packets of data are not given any special priority whereas; the VoLTE packets are given special priority.
