SA
Stand-Alone
A version of 5G that does not require a corresponding 4G network to function. The alternative is NSA (Non-Stand-Alone), which does rely on a 4G network for certain basic functions.

5G SA networks are more efficient and can offer lower latency (delay) compared to NSA networks.
The first 5G networks are NSA, although most network operators plan to upgrade to SA.
