The 5G transformation has reached a critical phase. 5G is the fifth generation wireless technology and also known as the fastest, most reliable and lowest latency technology ever. Yet, there are multiple scenarios determining how 5G rollouts will take place, including use of a Stand Alone (SA) or Non-Stand Alone (NSA) architecture.

The official website for NSA -- the National Security Agency National Security Agency/Central Security Service (NSA/CSS). NSA leads the U.S. Government in cryptology that encompasses both signals intelligence (SIGINT) and information assurance (now referred to as cybersecurity) products and services, and enables computer network operations (CNO). What We Do - National Security Agency NSA is the world leader in cryptology - the art and science of making and breaking codes. It is this expertise- from our people and technology- that allows us to accomplish the goals of discovering adversaries' secrets, protecting U.S. secrets, and outmaneuvering our adversaries in cyberspace while at the same time protecting the privacy rights of the American people.

The National Security Agency is the official U.S. cryptologic organization of the United States Intelligence Community under the Department of Defense.

GCHQ, which is the British counterpart to the NSA, has a similar surveillance program and shares data with the NSA. Many countries now have some sort of mass Internet surveillance now in place.

National Security Agency - ScienceDaily Nov 28, 2018 Non-standalone and Standalone: two paths to 5G - Ericsson Together with industry peers who have already deployed NSA 5G, they can start to benefit from the advantages of standalone 5G, which is the eventual architecture of all 5G radio networks. Two sides of the same coin. There have been discussions on the pros and cons of these two 5G tracks, sometimes to the point of rebuffing one option for the other.
