Mavenir scooped up $100 million in new funding to help boost the open radio access network (RAN) vendor’s position in the still coalescing 5G market. The latest funding round was led by Mavenir’s largest equity shareholder Siris, “along with investment from two highly strategic ecosystem partners,” the vendor added.

Mavenir President and CEO Pardeep Kohli in a statement said the proceeds would be used to “accelerate our capabilities in automation, sustainability and use of [artificial intelligence] as we enable our customers to efficiently deploy and operate open RAN-based end-to-end cloud-native networks.”

Verizon issued its fifth green bond for $1 billion in recognition of the fact that the carrier cannot rely upon on-site renewable energy to address the full environmental impact of powering its core products: 5G, 4G LTE and fiber backbone networks.

“We have to run them as efficiently as possible. Ergo, energy is our opportunity,” Verizon Chief Sustainability Officer (CSO) and SVP of Global Supply Chain Jim Gowen told SDxCentral.

Nvidia was awarded $5 million from the United States Department of Energy (DOE) to develop a data center cooling solution that combines two-phase direct-to-chip and immersion cooling techniques using low-global warming potential (GWP) refrigerants and per- and polyfluorinated alkyl substances (PFAs) that comply with environmental regulations.

The funding is part of the DOE’s Cooling Operations Optimized for Leaps in Energy, Reliability and Carbon Hyperefficiency for Information Processing Systems (COOLERCHIPS) program, which has also awarded funds to projects at HP, Flexnode, Intel Federal, universities and research centers. Nvidia’s award of $5 million represents the most amount of funds given to a project through the DOE program.
