OpenRAN Software Suite

The Parallel Wireless OpenRAN software suite enables OPEN RAN through the complete decoupling of hardware and software functionality. This functional separation enables the software suite to support any protocol split between DUs and CUs based on available backhaul/fronthaul options. Different RAN element functionalities consolidated on the platform, reducing complexity and making overall network maintenance simpler and less resource-intensive. Running on COTS x86-64 servers with minimum hardware dependencies, our world’s first and only OpenRAN software suite consists of the following components:

OpenRAN Controller: This performs the functions of an OpenRAN controller and is responsible for radio connection management, mobility management, QoS management, edge services, and interference management for the end user experience. Different RAN element functionalities are consolidated on this software platform, reducing complexity and making overall network maintenance simpler and less resource-intensive. As currently released, the OpenRAN controller module can virtualize a vBSC/2G gateway, 3G gateway/vRNC, 4G gateway/X2 gateway, Wi-Fi gateway, or any combination thereof. The fully virtualized and scalable controller functionality supports the E2 interface and works with multi-vendor RAN. As a result, it helps create a multi-vendor, open ecosystem of interoperable components for the various RAN elements and vendors. It can be software-upgraded to 5G RAN Controller functionality as non-standalone (NSA) and Standalone (SA) as the 5G standards are finalized and stabilized. Being a 5G native platform, it provides a smooth migration path to 5G utilizing any migration option.

Network Orchestration and real-time SON: This provides complete RAN orchestration, including self-configuration, self-optimization, and self-healing. All new radio units are self-configured by the software, reducing the need for manual intervention, which will be key for 5G deployments of Massive MIMO and small cells for densification. The self-optimization is responsible for necessary optimization related tasks across different RANs, utilizing available RAN data from all RAN types (macros, Massive MIMO, small cells) from the Analytics module. The predictive approach utilized by the Parallel Wireless platform, in contrast to the legacy reactive optimization approach, improves user experience and increases network resource utilization, key for consistent experience on data intensive 5G networks.

Network Sharing enabler: Infrastructure sharing will be a key for 5G networks. Parallel Wireless OpenRAN software suite enables MOCN/MORAN by having the ability to view the traffic and route to the proper core. This then allows RAN sharing to happen without complication to any of the home networks. The OpenRAN controller simply requires connections to each core and handles the heavy lifting of routing the traffic properly.

Benefits to MNOs 

By disaggregating hardware and software, the Parallel Wireless OpenRAN software platform creates a unified architecture through abstraction of traditional RAN and core network functions on a COTS server, and brings 5G software benefits (i.e. low latency and network slicing) across the network for ALL G (2G/3G/4G/5G), resulting in:

  • G Agility: a unified software-enabled architecture for past, present, and future Gs
  • Deployment flexibility for 5G, 4G, 4G, 2G through consolidation of network functions and RAN/core interfaces
  • Openness across RAN and core through fully 3GPPP compliant virtualized interfaces, enabling interop between all vendors and allowing for modernization of networks or selection of best of breed for 5G
  • Real-time responsiveness to subscriber needs through edge-centric architecture to deliver best performance for voice and data, outdoors or indoors, across 2G/3G/4G/5G, thereby reducing subscriber churn
  • OPEX reduction through network automation: with plug-n-play configuration and hands-free optimization, professional services spend on deployment or maintenance is reduced by up to 80% to deliver much lower OPEX across past, present, and 5G networks.

The Parallel Wireless OpenRAN software suite is fully virtualized. It can be deployed as a VNF (it is a Composite VNF, which includes a federation of VMs behaving like a single logical entity). The software is ETSI’s MANO compliant, and agnostic to the underlying data center infrastructure so can use any Intel x86 server, and can be installed with all major market leading hypervisors (Linux KVM, VMware ESXi). It can be managed via any standards-compliant VNF Manager (VNFM), as well as any NFV Orchestrator (NFVO). Partnerships are in place with Intel, RedHat, VMware, HPE, and Dell. SRIOV, DPDK, PCI Passthrough is fully supported.
