Connecting calls and helping people communicate has always been the focus of telecommunications.

The 4G era offered the ability to innovate using more than just a keypad. These changes helped mobile operators compete against the over-the-top web-based service providers and establish an environment to launch new user experiences for any generation of the mobile device.

The operational paradigms of 4G are rapidly shifting as 5G SA with Voice over New Radio (VoNR) services inspire new, more advanced features.

Continuing the evolution, 5G brings the opportunity to make a mobile phone more than just a phone.

In addition to vastly improved voice and audio quality, new use cases such as wayfinding, augmented and virtual reality (AR/VR), and other connected, innovative devices are possible. FASTER!

Mavenir supports this evolution with many options for each customer’s unique needs.


New use cases such as IoT devices, factories, robotics, smart cities, sports venues, and even autonomous driving open new innovative opportunities for CSPs. Mavenir provides a single IMS core and a single set of services throughout the evolution across either 4G or 5G, with seamless mobility.

Mavenir’s Cloud-Native IMS is the foundation for an ever-changing yet robust and secure IP communications service. The IMS has the intelligence to deliver subscriber services no matter where they are located or which access technology is available to them, such as 4G LTE, 5G NR, or Wi-Fi as they move from place to place.

Voice over LTE (VoLTE) and Wi-Fi (VoWi-Fi)

Much of the world is still evolving to 5G, and a cloud-native IMS is an important investment.

VoNR, Voice over LTE (VoLTE), and Wi-Fi (VoWi-Fi) services can all be deployed using the same IMS network.

Mavenir’s cloud-native IMS core network infrastructure delivers next-generation communication services allowing users to collaborate using voice, video, and messaging. No matter where the subscriber is located or if they are connected to the cellular network directly or through Wi-Fi, Mavenir’s solution delivers a consistent user experience.

More than being 10X faster than 3G, VoLTE or VoWi-Fi empowers CSPs to provide rich voice, video, and messaging services as a core offering. The web-scale architecture significantly improves network economics with scalability, efficiency, and automation. This VoLTE and VoWi-Fi solution provides significant cost savings and a clear path to 5G while enhancing the user experience and generating incremental revenue.

Prepare for the 5G Future

  • Transform your network for 5G Voice with support for both VoLTE and VoNR, using a common, cloud-native IMS core.
  • A single IMS investment can support voice services over 4G or 5G, guarantee service parity, and facilitate voice continuity between 4G and 5G

Enhance Operations

  • Operate in any cloud environment, public or private.
  • Any device or service and all applications can run on an automated network, utilizing open architecture, containers, and artificial intelligence.

Innovate and Offer New Services

  • Use Kubernetes or any hybrid cloud strategy or platform – private or public clouds — deployed as stateless microservices in containers.
  • Respond to the market quickly and efficiently deploy new services.
