What is PGW?

PGW stands for Packet Data Network Gateway. It is a crucial component in a 4G LTE (Long-Term Evolution) network architecture. The PGW acts as the point of interconnect between the LTE network and external packet data networks (PDNs) like the internet. It handles tasks such as IP address allocation, policy enforcement, charging, and data routing to and from user devices. It is a key element for providing mobile broadband services.

What other technologies are related to PGW?

PGW Competitor Technologies

GGSN

Gateway GPRS Support Node. GGSN performs similar functions to the PGW but is used in 2G and 3G networks (pre-4G). As networks evolve to 4G and 5G, PGW replaces GGSN.
