What is SGW?

SGW typically refers to the Serving Gateway in a 3G or 4G (LTE) mobile network architecture. It acts as a data router and mobility anchor for the user plane, forwarding data packets between the eNodeB (base station) and the PDN Gateway (PGW). It's a crucial component for user data transfer, mobility management within the LTE network, and session management.
