Radio Convergence (5G, LTE and WiFi)

As the 5G radio will be deployed mainly in very dense areas and as the 5G environment presumes a complete coverage, the 5G ecosystem has to include other radio access networks (even when the migration phase is over). LTE and WiFi are the most preeminent in term of energy consumption, capacity and delay, especially addressing the macro- cell deployments in less populated areas and indoor communication using licensed or unlicensed spectrum.

For providing a coherent and efficient architecture, the 5G environment should consider the deep convergence between 5G, LTE and WiFi for radio access network management, spectrum management, access network discovery and selection, carrier-aggregation and multi-homing support, authentication and authorization, resources allocation and mobility, monitoring and real-time analytics, etc.
Based on the experience gained by developing the OpenEPC – the 2G / 3G / 4G / WiFi convergent core network –, we are able to provide an extensive research and practical implementation of:
  • RAN management – especially for dynamic cell configuration and spectrum allocation;
  • Access Network Discovery and Selection – leveraging the subscriber, device and locality features;
  • Carrier aggregation and multi-homing support – for increasing the capacity per device;
  • Convergent authentication and authorization;
  • Policy based resources allocation and charging;
  • Mobility support;
  • Monitoring and real-time analytics.
