Final answer:
A 4G home network uses a Gateway for device authentication, mobile device management, and tunneling setup, ensuring secure network access and communication.
Step-by-step explanation:
Each 4G home network consists of a Gateway that handles device authentication, mobile device management, and tunneling setup. The Gateway is a critical component of cellular-based home networking solutions, ensuring secure access and communication between the mobile network and the devices within the home. It is responsible for establishing and maintaining the connection to the 4G network, implementing security protocols for authentication, managing the various devices connected to the network, and setting up the necessary tunnels for data transmission.
