Open RAN Outreach Act This bill requires the National Telecommunications and Information Administration (NTIA) to conduct outreach and provide technical assistance to small communications network providers to raise awareness of the benefits, uses, and challenges of Open RAN networks and other open network architectures. Open RAN networks are wireless networks that follow the Open Radio Access Network approach to standardization, promoting the use of open interface standards in the portion of the telecommunications network that connects wireless devices (e.g., mobile phones) to the core of the network. The NTIA must also conduct outreach and provide assistance regarding participation in the Wireless Supply Chain Innovation Grant Program.
