The growing smartphone penetration and 5G networks rollout in upcoming years, the demand for IP-based voice solution in Germany VoLTE and VoWiFi technology is anticipated to grow in the double digits in the next 10 years. As telecom providers dismantle outdated 3G networks, Voice over LTE (VoLTE) is the voice service of choice, offering millions of subscribers HD (high definition) voice quality, shorter call setup times & more reliable connections.
In fact, VoWiFi is being deployed at an ever-increasing rate in order to cater for the demand for indoor coverage and smooth handover across network types. Wi-fi 6 and private 5G networks are also a growing phenomenon to make low-cost high-quality voice calls possible even at low signal areas to further enhance VoWifi services, whereby voice calls get connected like that for Internet data charge.
The market is expected to grow from USD 4000.0 in 2020 to USD 1,092.6 Million by 2025 with a CAGR of 23.6% over the next five years and will reach USD 11900.0 million by 2030.

Rising 5G Deployment and Network Expansion
Germany's 5G network, the use of VoLTE and VoWi-Fi services is becoming more widespread. Indeed, Deutsche Telekom, Vodafone and Telefonica, large operators investing in the amount of 5G coverage it has across the country to improve Voice quality, Latency, and successfully connecting calls. With LTE and 5G networks replacing old circuit-switched infrastructure, VoLTE has emerged as the standard for high-definition voice services.
In addition, the VoLTE handovers enabled by 5G help facilitate a seamless user experience. The gradual shutdown of 3G networks, which was fully completed in 2021, has also pushed VoLTE penetration by encouraging users to transition to LTE and 5G, rendering VoWi-Fi a vital assistive option for indoor connectivity, particularly in rural and suburban areas that have less and even nonexistent cellular signals.
Growing Demand for High-Quality Voice Services
Consumer demand for better voice quality and seamless connectivity are so widespread in Germany that the adoption of VoLTE and VoWi-Fi is increasing. Compared to legacy networks, VoLTE delivers HD voice clarity, faster call setup times and better call stability. VoWi-Fi is also being utilized by businesses and enterprises in areas where traditional mobile signals cannot penetrate buildings thus improving two-way communications within a building.
This has also propelled demand for VoWi-Fi adoption since this technology is enabling continuous voice services during work-from-home and hybrid model office services. Moreover, Germany has high smartphone penetration, and most devices are factory-configured for VoLTE and VoWi-Fi, making it easy for users to enjoy high-quality voice calling with minimal effort to adopt, encouraging big-scale usage in both urban and rural areas.
Increased Adoption of VoWi-Fi for Enterprise Communication
German enterprises are rapidly adopting VoWi-Fi to improve workplace communication, especially in high-rise buildings and below-ground office spaces where mobile coverage is weak. VoWi-Fi is being deployed in combination with Unified Communications (UC) solutions to give large organizations and SMEs the ability to make calls over corporate Wi-Fi networks without needing cellular coverage.
In Germany, this trend is assisted by the strong fiber-optic and broadband infrastructure, which can guarantee stable VoWi-Fi connectivity. With increasing numbers of people working remotely and in hybrid work models, VoWi-Fi solutions available in conjunction with business VoIP services are now much desired, as these can give employees continuity of communication anywhere in the world without being dependent on voice networks and cellular voice plans, saving on costs.
VoLTE and VoWi-Fi Integration with 5G Standalone (SA) Networks
The country is moving toward 5G Standalone (SA) networks that do not rely on any LTE infrastructure. This shift will accelerate the evolution of VoLTE and VoWi-Fi into 5G-native voice, providing the opportunity for enhanced performance and lower latency. 5G Ras Interfaces: Operators such as Deutsche Telekom and Vodafone are trialing Voice over New Radio (VoNR) as a substitute for legacy voice infrastructures while also working to provide handover between VoLTE and 5G VoNR calls.
At the same time, VoWi-Fi is advancing with edge computing integration, allowing for real-time processing of voice data and AI-enhanced call quality improvements. This makes Germany a pioneer in the provision of next-generation voice services: at the end of the day, all communication flows through an IP-based communication network from end to end, as traditional, circuit-switched voice networks are retired.
