Radisys Introduces CellEngine 5G Radio Access Network (RAN) Technology

Radisys, the services acceleration company has announced the availability of its CellEngine™ 5G RAN Version 1.0 software for communications service providers. By delivering modular well-tested software, available as licensed source code, Radisys is enabling a time-to-market advantage for its global communications service provider customers. Initial customer deployments are now leveraging the software for Internet of Things (IoT), Cloud-RAN and LTE-Advanced functionality.

Communications service providers around the world are pursing 5G network evolution as part of their overall strategy to deliver new revenue-generating 5G services to their subscribers. Radisys’ CellEngine 5G RAN Version 1.0 software provides communications service providers with a tiered roll-out of 5G features, enabling their 5G network architecture development and deployment. The software’s initial capabilities include delivering Carrier Aggregation (CA) and Licensed Assisted Access (LAA) for multiple carriers as well as LTE Category M1 (CAT M1) and Narrowband (NB) for IoT and will later add 28 GHz millimeter wave technology for true 5G speeds.

Radisys’ 5G RAN licensed source code includes Cloud-RAN, IoT and LTE-Advanced features as key stepping stones toward enabling 5G deployments.

  • Cloud-RAN:
    Complementary to Software-Defined Networking (SDN) and Network Functions Virtualization (NFV), Cloud-RAN is based on open platform and base station virtualization, enabling processing aggregation and dynamic allocation of resources from a centralized processing unit
  • IoT:
  1. LTE Category-M1: delivers an IoT optimized version of LTE technology that supports additional cost reduction measures, lower data rates and reduced transmit power
  2. NarrowBand IoT (NB-IOT): enables a wide range of devices and services to be connected using a Low Power Wide Area Network (LPWAN) radio technology standard
  • LTE-Advanced features: 
  1. Carrier Aggregation: allows communications service providers to combine a number of separate LTE carriers, enabling them to increase their peak user data rates, to increase overall network capacity and to exploit fragmented spectrum allocations.
  2. Enhanced ICIC (eICIC): serves as an interference manager as part of a Heterogeneous Network (HetNet) to reduce interference between the macro and pico layer of the network and thereby ensure faster data transmissions
  3. Licensed Assisted Access (LAA): enables the combination of LTE in unlicensed spectrum with LTE in the licensed band, thereby delivering a fatter pipe with faster data rates for a more responsive user experience
