In this part of the video, the speaker discusses the evolution of voice calls from 2G to 3G and the recent introduction of VoLTE (Voice over LTE) technology on 4G networks. VoLTE allows for crystal clear HD calls on smartphones and is carried over the data network, offering improved voice quality and faster call setup times. The video explains that VoLTE works by carrying voice calls over IP networks, providing flexibility to enhance voice calls and avoid the need to switch between 4G and 3G networks for voice services. The history of VoLTE’s development and its advantages over traditional circuit switching for voice calls are also highlighted.

In this segment of the video, VoLTE (Voice over LTE) technology is explained. VoLTE uses 4G data connectivity to send voice calls as IP packets, similar to WhatsApp or Skype calls. The benefits of VoLTE include better user experience, HD calling with crystal clear voice quality, no drop in background data speeds, faster call connection time (less than 1 sec), and improved battery life as users don’t switch between different network types. The history of VoLTE development, starting from opposition to IMS network to its standardization by GSMA and 3GPP, is also outlined, with the first VoLTE trials seen in 2012.

In this segment of the video, the presenter discusses the evolution of mobile technology from 2G to 4G networks. They explain the phases such as GPRS/Edge for 2G, 3G with improved data speeds and voice support, H/H+ as a fast 3G network, and the latest 4G or LTE network. VoLTE (Voice over LTE) was first available in 2014, with SingTel Singapore being the first operator to launch commercial VoLTE services. The presenter explains how to enable VoLTE on both Android and iPhone handsets, detailing the steps to access the settings and enable VoLTE for voice calls over 4G networks. They also note that most smartphones now support VoLTE, but operator compatibility may vary.
00:09:00
In this segment of the video, it is explained how to enable VoLTE on Android devices using a secret menu. VoLTE support is not default on all handsets; mobile operators and handset manufacturers need to work together to enable it. The mobile operator needs good 4G coverage and to provision VoLTE services. Users need a VoLTE-supported handset with the right software and an ISIM or USIM card. Users can control VoLTE services through a switch on the handset. VoLTE brings benefits like increased spectrum efficiency by repurposing older technologies like 2G for LTE.
00:12:00
In this segment of the video, the key points discussed are:
– VoLTE networks can handle both data and voice simultaneously, leading to better spectrum utilization and higher subscriber satisfaction.
– Voice services remain a significant revenue driver for mobile operators, making it essential to provide a superior voice experience.
– VoLTE simplifies network operations by combining voice and data on the same LTE network, reducing operational costs.
– VoLTE enables faster integration of new services like chat and multimedia to compete with over-the-top (OTT) players effectively.
– Challenges facing VoLTE adoption include limited operator and handset support, increased network complexity, LTE coverage requirements, and the need for device validation.
– Quality of Service (QoS) concepts in VoLTE prioritize voice traffic during network congestion to ensure real-time voice communication.
