Mavenir is teaming up with Xilinx on the development of a new generation of unified 4G/5G massive MIMO (mMIMO) designs for OpenRAN network deployments. The first mMIMO 64TRX joint solution is expected to be available in Q4 2021.

This 64 antenna system will enable the world’s first OpenRAN compliant networks with up to 400MHz instantaneous bandwidth in a compact form factor using the Xilinx RFSoC DFE and Versal AI for advanced beamforming, delivering a fully integrated hardware and software O-RAN compliant mMIMO solution.

Mavenir's software supports Multi-User MIMO with up to 16 layers, advanced receiver algorithms, full digital beamforming - all running on Mavenir's open and flexible cloud-native platform, as well as on other cloud platforms.

The two companies have successfully completed end-to-end integration of a first-generation mMIMO system using OpenRAN principles. Developed at the Mavenir Lab in Bangalore, India, the integration covered multiple deployment scenarios and was evaluated by six global operators. Mavenir delivered the Virtualized RAN (vRAN) support for mMIMO, including Core Network, CU and DU, with Xilinx providing the Category B O-RAN Radio Unit. 

“This integration demonstrates an efficient Open RAN massive MIMO solution to achieve diversification of the telecommunications supply chain,” said Pardeep Kohli, President and CEO of Mavenir. “This is an important milestone in the delivery of open and interoperable interfaces enabling the deployment of mMIMO in high density, high mobile traffic metro areas.”

“We were early proponents of Open RAN technology along with Mavenir and actively led in standards development in the industry through many field trials around the world,” said Liam Madden, executive vice president and general manager, Wired and Wireless Group at Xilinx. “With the investment we have done on our market-leading wireless radio technology and massive MIMO R&D, we are excited to collaborate with Mavenir to bring our collective technology and radio system expertise together that will accelerate the deployment of market leading 5G
