Building upon existing 4G Long-Term Evolution (LTE) infrastructure, 5G is designed to improve bandwidth, capacity, and reliability of wireless broadband services. The technology is intended to meet increasing data and communication requirements, offering capacity for tens of billions of connected devices.
While 5G is expected to deliver a broad range of improvements and better user experience, supply chain, deployment, network security, and competition and choice vulnerabilities could negatively impact the security and resilience of 5G networks, CISA says.
