100% Software Defined

NVIDIA Aerial is a highly-programmable PHY layer and has the capability to support L2+ functions seamlessly.

High Performance and AI Ready

With GPU-accelerated processing, complex computations run 20 times faster than existing L1 processing solutions. AI-based algorithms for L1 functions give improved performance results.


100% commercial off-the-shelf (COTS) hardware support with Aerial SDK makes it easier to deploy cloud-native services.


NVIDIA Aerial is a set of SDKs that enables GPU-accelerated, software-defined 5G wireless RANs. Today, NVIDIA Aerial provides two critical SDKs: cuVNF and cuBB.

The NVIDIA cuVNF SDK provides optimized input/output (IO) and packet placement on the GPU whereby 5G packets are directly sent to GPU memory from GPUDirect capable network interface cards (NICs). cuVNF provides speed at line rate for I/O. It enables developers to create other VNFs e.g. Deep packet inspection, firewall, vRAN, etc.

The NVIDIA cuBB SDK provides a fully-offloaded 5G Signal Processing pipeline (5G L1) which delivers unprecedented throughput and efficiency by keeping all physical layer processing within the GPU’s high-performance memory. NVIDIA cuPHY SDK provides a fully-offloaded 5G Signal Processing pipeline (L1 5G Phy) which delivers unprecedented throughput and efficiency by keeping all physical layer processing within the GPU’s high-performance memory. Best performance for LDPC on COTS. It is the single software programming model that goes from Pico cells to CRAN to DRAN.

cuPHYTools is the generator for network traffic for cuPHY providing seamless packet flow for faster transception. cuPHYTools GPU-DPDK support to directly transfer data from NIC to GPU memory using GPU-Direct function.

A newly GPU enabled DPDK (Data Plane Development Kit) helps developers easily add GPU acceleration to their existing RAN architecture. and NVIDIA CUDA-X signal processing libraries like cuFFT and NPP offer drop-in APIs and over 5000 primitives for image and signal processing.

Fast data processing with 5T for 5G technology

5T for 5G technology brings precise time synchronization and other functionalities for faster fronthaul communication. Latest Mellanox NICc such as ConnectX-6 Dx SmartNICs and BlueField-2 Data Processing Unit (DPU) provide the capability. ConnectX-6 Dx is industry’s first SmartNIC to offer this super precise time synchronization for eCPRI and provides a 5-in-1 solution: high-throughput, low latency network connectivity, low power, a broad set of in-hardware acceleration capabilities

NVIDIA Aerial is Kubernetes based

NVIDIA Aerial SDK is cloud native providing resources for faster execution of RAN functions. Aerial SDK is Kubernetes based to support provides container-orchestration for ease of container deployment and management. Cross platform support with AWS, Azure and NVIDIA EGX stack give wide range of services that can run edge applications giving high performance. NVIDIA EGX is an enterprise-grade accelerated computing platform that enables companies to run real-time low-latency applications at the edge. To achieve the highest level of reliability, Aerial SDKs and libraries undergo extensive testing against the EGX software stack with an emphasis on performance and long-term stability.

Announcing the NVIDIA Aerial Developer Kit
