Industry Trends and Drivers:

• Growing demand for high-quality voice services:

VoLTE offers HD voice quality, giving customers clearer sound than 2G and 3G networks. Its wider audio bandwidth captures all acoustic frequencies and reduces background noise. This significant improvement in call quality attracts both consumers and businesses. On 2G and 3G networks, mobile voice calls require switching between voice and data services, often interrupting internet use. VoLTE, however, supports high-speed data and voice simultaneously on the LTE network. It ensures that services like app use, video streaming, or browsing are paused during a call. This creates a more user-friendly experience, especially for professionals and mobile users.

• Increasing smartphone adoption:

Today, most new smartphones have VoLTE support. This allows many users to access VoLTE services without extra accessories or app integration. As more people adopt smartphones, especially in emerging markets, the number of VoLTE users grows. Smart devices are popular, encouraging VoLTE use. Users switch to phones that support voice calls over LTE networks. Many 2G/3G users are moving to 4G/5G phones, which often include VoLTE. This shift is driven by affordable smartphones, boosting the VoLTE market.

• 4G and 5G network expansion:

4G and 5G networks are crucial for VoLTE services. Telecom operators invest heavily to boost network capabilities, ensuring higher data speeds and lower latency. As these networks grow, they support VoLTE, which uses LTE technology for voice calls. Compared to older technologies, 4G and 5G offer greater reliability and coverage. Users experience fewer dropped calls and better call quality. This improvement encourages them to adopt VoLTE as their main way to make voice calls. With increased reliability, user confidence and satisfaction in VoLTE also rise.
