A key architectural feature that usually distinguishes a home internet gateway is its integration of multiple functionalities, such as routing, firewall, and network address translation (NAT). This allows it to manage both local area network (LAN) traffic and connect to the wide area network (WAN) efficiently. Additionally, many home gateways include wireless capabilities, enabling Wi-Fi connectivity for various devices within the household. This combination of features supports seamless internet access and device communication in home networks.
