As Telefonica continues to enhance its network and crystallize 5G plans, the Spanish-based multi-national operator this week, through its Telefonica Innovation Ventures investment arm, announced an investment in open radio access network infrastructure Altiostar, which specializes in software-based, virtualized RAN equipment.
Through industry consortia the Telecom Infra Project and O-RAN Alliance, a range of operators and vendors are collaborating to develop specifications establishing interoperability for multi-vendor RAN environments.
