• 4T4R outdoor O-RAN 7.2x compliant O-RU

• Expanded usable bandwidth for higher throughput

• 4096-QAM capability in controlled environments

• Sustained 1 Gbit/s delivered up to 3x farther under comparable power and bandwidth conditions

• NVIDIA AI Aerial CU/DU integration

• Demonstration with NVIDIA DGX Spark

• Distributed MIMO (dMIMO) coordination

• Transmitter efficiency enabled by Eridan’s direct polar architecture

As coordination density increases, signal quality at transmission becomes the limiting factor.

Spectral efficiency directly affects:

• Modulation stability

• Coverage at high data rates

• Energy per bit

• Network densification economics

The 4T4R architecture extends Eridan’s direct polar design into higher-capacity deployments, enabling scalable performance without proportional increases in power or hardware complexity.

The 4T4R platform is designed for coordinated, compute-driven RAN environments. It enables:

• Stable high-order modulation at scale

• Transmitter precision required for distributed MIMO (dMIMO) coordination

• Interoperability with AI-native CU/DU platforms, including NVIDIA AI Aerial

• Scalable capacity without proportional increases in transmit power

By improving spectral efficiency at the physical layer, 4T4R supports higher coordination density in AI-native networks.

March 3 I 9:30 – 10am CET | Booth 2C70 (Rakuten Booth)

Eridan representatives will join NVIDIA, Rakuten Symphony, NTIA, and Northeastern University to discuss operational performance, coordination challenges, and commercialization pathways for distributed MIMO architectures.

Attend the session or schedule a follow-up discussion with Eridan at Hall 5, Booth 5K26.
