Verizon (NYSE: VZ) announced that it has deployed an Open Radio Access Network (O-RAN)-based distributed antenna system (DAS) with equipment interoperability in two Texas locations – The University of Texas Moody Center and the Austin Convention Center. The company says that these are the first commercially deployed DAS systems in its network using O-RAN interfaces between cellular RAN components from different vendors.
Both systems use a Samsung virtualized distribution unit (vDU) with an O-RAN interface to a CommScope (NASDAQ: COMM) DAS head-end. Verizon is the anchor tenant on both DAS installations, and is delivering its 5G Ultra-Wideband service throughout each venue. The CommScope DAS is designed to accommodate input from multiple MNOs whose signals can be transmitted throughout the venues.
Verizon says this commercial deployment marks a major step towards larger-scale, multi-vendor deployments using O-RAN. The company adds that interoperability between components from different manufacturers materially impacts the cost of power, space and cooling by eliminating unnecessary RF equipment, and improves overall system reliability.
“The massive evolution of our network over the past few years including our move to a cloud-based architecture, widespread virtualization and our aggressive adoption of O-RAN standards and capabilities has enabled us to show O-RAN interoperability success in a commercial environment,” said Adam Koeppe, Verizon SVP of Technology Planning.
The company points out that the transition to Open RAN, with open and interoperable interfaces between different hardware and software components, has the potential to provide both operators and end users alike with benefits such as deployment flexibility, faster innovation in an open environment, and greater service options.
Verizon claims that it is among the leaders in developing and adopting O-RAN standards. Earlier this year, the company reported that it already has deployed more than 130,000 O-RAN capable radios in its network.
