Keysight Technologies, Inc. is enabling Intel to develop and validate massive multiple-input, multiple-output (mMIMO) beamforming designs for use in Open Radio Access Networks (RAN) with Open RAN Studio, accelerating the adoption of Open RAN architectures by mobile network operators. By separating software from hardware through open interfaces and virtualization, Open RAN network architectures allow mobile operators to mix and match network elements from different vendors for increased flexibility and reduced costs. Operators can further improve network performance by implementing mMIMO, a technique of using large numbers of antennas to send and receive data to boost coverage and capacity.

While Open RAN and mMIMO offer significant advantages, they also present significant conformance and interoperability challenges. Implemented on a single Intel Agilex?? 7 system-on-chip field-programmable gate array (SoC FPGA), the Intel solution delivers efficient, high-quality signals through the antenna array using an Open RAN-compliant, weight-based dynamic beamforming method.

Intel ensured that its mMIMO digital beamforming solution could be seamlessly deployed in an Open RAN network by using the Keysight Open RAN Studio solution to validate its interoperability within the Open RAN ecosystem. Open RAN Studio enabled Intel to optimize the performance of its complex mMIMO beamforming technology to accommodate the large number of simultaneous connections needed to deliver the high data rates needed for 5G services. Designed for LTE and 5G Open RAN Radio Unit (O-RU) testing, Open RAN Studio includes powerful Open RAN focused tools to construct, play, capture, and measure Open RAN traffic over Ethernet fronthaul interfaces.

Open RAN Studio is part of the comprehensive Keysight Open RAN Architect (KORA) portfolio that provides test solutions for functional, performance, energy efficiency, security, and artificial intelligence and machine learning training and optimization.
