Mavenir, an upstart end-to-end cloud-native network software provider and Xilinx, a leader in adaptive computing, announced today the companies are collaborating to bring to market a unified 4G/5G O-RAN massive MIMO (mMIMO) portfolio to enable Open RAN deployments. The first mMIMO 64TRX joint solution is expected to be available in Q4 2021.

Working together, the two companies have successfully completed end-to-end integration of a first-generation mMIMO solution using Open RAN principles. Held at the Mavenir Lab in Bangalore, India, the integration covered multiple deployment scenarios and was evaluated by six CSPs, all leading 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,” says Pardeep Kohli, President and CEO, 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 O-RAN massive MIMO radio solutions.”

With history of leadership success in various 4G and 5G network deployments worldwide, the companies are jointly developing the next generation of mMIMO products which will bring the world’s first O-RAN compliant 64TRX mMIMO products that support up to 400MHz instantaneous bandwidth in a compact form factor. Mavenir’s vRAN 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.

These products will leverage Xilinx’s technology platform including RFSoC DFE and Versal AI for advanced beamforming, delivering a fully integrated hardware and software O-RAN compliant mMIMO solution.

The wireless industry’s focus is squarely set on massive MIMO as mid-band spectrum 5G deployments continue, particularly following the record high mid-band 5G spectrum auction that concluded in the U.S. earlier this year. Massive MIMO is especially important in mid-band 5G networks because it allows operators to densify network coverage, increase capacity and coverage, and reduce the need for incremental outdoor sites, all of which translates to less labor and lower costs.

Mavenir and Xilinx have not yet disclosed the specifications for the equipment, but claim the equipment at the top of the portfolio will feature a 64-antenna array for transmitting and receiving signals and support up to 400 megahertz of bandwidth. The initial supply of radios will support C-band spectrum in the U.S., and the companies plan to later support mid-band spectrum for 5G deployments in Europe, the Middle East, and India.

The vendors are coming together to prove that “open RAN massive MIMO radios are a reality, and we will deliver that to the market. Our first open RAN massive MIMO radio will be labs ready by early Q4 and field-trial ready by the end of the year,” said Gilles Garcia, a senior director at Xilinx.

“5G Open RAN has significant momentum in the market with ABI Research forecasting network vendor spending to reach $10 billion by 2026-27 and then surpass traditional RAN at $30 billion by 2030,” said Dimitris Mavrakis, senior research director of 5G at ABI Research.

“As Mavenir and Xilinx continue to work together to accelerate O-RAN-based massive MIMO adoption, their solutions will be well-timed to serve this high-growth market with the higher spectral efficiency, performance, power efficiency and cost needed as 5G demand intensifies.”
