Mobile and wireless technologies provide an ever-increasing number of opportunities for companies to innovate and grow. Wireless telecommunications providers are experiencing dramatic growth in mobile data transmission, driving demand for mobile devices supporting data-intensive consumer-based applications, such as location-based services and 3D gaming. Mobile and wireless technologies can be complex. Their associated infrastructure is crucial to mission-critical applications such as defense, emergency response, and business, including logistics, smart city, networking connectivity, supply, and more.

Mobile network infrastructure is based on a software-defined architecture that allows greater flexibility, increased adaptability to new capabilities, and automation, allowing wireless operators to compete better.

Service-based Architecture

New mobile and wireless systems were designed from the ground up instead of adapting to previous generations. Previous generations were all built on top of the following previous generation. Architecture is a Service-based Architecture with crucial components:

  • Authentication Server.
  • Policy Control.
  • Network Slice Selection.
  • Session Management.
  • User plane.
  • Access and Mobility Management.

Unified Data Management.


5G architecture has a decentralized approach that enables co-locating 5G core functions in the data centers at the edge of the network, thus reducing distance and latency while increasing speed. For example, a content provider of video streaming services may install 5G equipment in proximity to its video streaming servers. This approach is unique and differs from previous generations of wireless networks, comprised of a packet core through which most of the wireless traffic would traverse.

5G architecture also introduces the concept of network slicing, which allows for optimizing slices of the network for particular application requirements. A network slice is a logical extension of functionality customized as a service for a specific application. With slices, operators can optimize the network infrastructure for the optimal performance of particular applications.
