  • Publication number: 20240023008
    Abstract: A network device or system can operate to enable a security pass-through with a user equipment (UE) and further define various virtual functions between a physical access point (pAP) and a virtual AP (vAP) based on one or more communication link parameters (e.g., latency). The security pass-through can be an interface connection that passes through a computer premise equipment (CPE) or wireless residential gateway (GW) without the CPE or GW modifying or affecting the data traffic such as by authentication or security protocol. The SP network device can receive traffic data from a UE through or via the security pass-through from a UE of a community Wi-Fi network at a home, residence, or entity network.
