Build 5G Using Modular Architecture, Says CNAS

As the U.S. moves toward 5G, it should focus on modular architecture with open interfaces, which would make networks less reliant on equipment vendors Huawei, Nokia, Ericsson and Samsung, the Center for a New American Security said Tuesday. The U.S. “has the opportunity to regain momentum by taking a fresh approach to 5G” in the aftermath of COVID-19, CNAS said. It warned the pandemic will likely slow deployments. It said: “A modular architecture allows an operator to choose multiple vendors for a range of offerings, rather than being locked in with a single large integrated vendor. Open interfaces -- the ability of equipment from any vendor to work with that of another -- make that possible. Such a shift means upending the industry status quo.”
