Open RAN radios present different challenges in terms of size, weight, power and cost

Now that the basics of Open RAN standardization are largely gone, the industry’s focus is on building out the ecosystem or partners to accelerate adoption. In an interview at Mobile World Congress Barcelona, ​​Joe Barry, VP of Wireless Communications at Analog Devices, spoke about how the company’s new radio unit (RU) reference designs and system on chip (SoC) are contributing to this.

Barry highlighted just two of the new reference designs and discussed ADI’s Massive MIMO C-band RU and the Macro 5G reference design, both of which are Open RAN compliant. ADI worked with Benetel and Marvell on the first design, with the former providing low PHY software and the latter its OCTEON Fusion baseband processor and beamforming technology. The Macro 5G reference design was developed in collaboration with Intel.

When it comes to the new SoC, Barry said the 8T8R RadioVerse SoC is a more complete and “true” radio platform solution. “ADI has a strong history in terms of what we call the thin radio, or the classic RF frontend, but this [SoC] is a very important integration of digital capabilities. So an all-digital front-end, which has a lot of the processing and algorithms you need in these radios.”

The SoC solution, which supports Open RAN split 7.2x and according to Barry helps address some of the biggest challenges the industry faces in bringing these Open RAN radios online, including reducing size, weight, power and costs.

Commenting on the general state of play, Barry said that the evolution of 5G and the activity around Open RAN has “has been at a significant pace” in the more than two years since ADI was last in Barcelona, ​​as a result of the ongoing COVID-19 -19 pandemic.

“The pace of innovation for 5G is really gaining momentum,” he said. “Utilities [with Open RAN] it’s really about building momentum [around] deploying the network… One of the areas that ADI is really committed to is the challenge of enabling a much more vibrant ecosystem by developing radio units that comply.” He added that the company sees “an ever-increasing demand” for the types of infrastructure radio units available.

“Our commitment to the ecosystem and our partnerships, and our open and transparent way of investing in the ecosystem, will help accelerate the pace of innovation,” said Barry.
