4G / LTE

Market-leading and award-winning Radisys Trillium LTE software enables customers to deploy all sizes of LTE base stations — from femto to macro — and the entire Evolved Packet Core.

Trillium CDTrillium wireless protocol software from Radisys is synonymous with high quality and superior performance. Our team has leveraged more than 20 years of innovation to create a complete LTE (Long Term Evolution) wireless protocol software solution for the 4G market, enabling true mobile broadband service with unprecedented data rates, superior mobility support and low round-trip latency.

Trillium LTE wireless protocol software addresses LTE Femtocells (Home eNodeB) and pico / macro eNodeBs as well as the Evolved Packet Core (EPC) Mobility Management Entity (MME), Serving Gateway (SWG), Evolved Packet Data Gateway (ePDG), etc. These standards-based Trillium LTE wireless protocols allow customers to rapidly develop LTE infrastructure to compete for early design wins in the dynamic LTE marketplace.


Trillium LTE wireless protocol software solutions meet the unique requirements of network equipment providers, including:

  • Comprehensive protocol support from LTE Femtocells to the EPC
  • Standards-based protocols starting with the latest 3GPP Rel-9 standards for the E-UTRA 36 series specifications
  • Pre-integrated software to simplify development and enable more focus on application development
  • Reference applications for key LTE interfaces including LTE-Uu, S1, S6, S7, S10, X2, etc.
  • Multi-threaded stacks optimized for multi-core processing architectures, including fast path modules for critical data plane protocols like eGTP
  • Experienced Professional Services for rapid integration and full platform design and development support

Trillium LTE wireless protocol software enables network equipment providers to reduce project risk, cost and complexity while accelerating time-to-market. And, when coupled with the T40 ATCA platform, which delivers 50% cost-per-bit reduction, Trillium software enables the high efficiency core that operators need to increase access performance for VoLTE applications.
