b'AT&T has an integrated spectrum offering that works in all those areas, Spencer says. If you consider the splinters of potential unique spectrum, theres a cost of fabrication for deploying those end user devices.This can get expensive, so working with a service provider like AT&T on a spectrum arrangement can be highly valuable for the DOD. Establishing a Zero-Trust Environment Security is a top priority for the Pentagon and for AT&T. One of the challenges is demonstrating that 5G can meet the security requirements and the cybersecurity posture that the DOD requires, Singer says. For AT&T, that means showcasing via Priority and preemptionprototypes how its 5G implementationallow first responders tosupports a zero-trust architecture and communicate with minimalmeets additional security requirements.or no interruption. AT&T is among several companies collaborating on a 5G testing site to write the book on 5G cybersecurity with the National Cybersecurity Center of Excellence (NCCoE), a part of the National Institute of Standards and Technology (NIST). 5G already has standards for cybersecurity set by 3GPP, a global partnership of telecom standards bodies. The NIST project is different. It is working on real-world tests with a group of equipment and software vendors, mobile operators and security service providers. It plans to literally demonstrate and document the strong security than can be achieved in 5G networks.Having 3GPP involved in global requirements and standards also puts the U.S. in a stronger global position, given that there are consortiums, standards and requirements worldwide. 16'
