A recently granted patent (Publication Number: US11910052B2) discloses an entry device designed to facilitate communication between an in-home network and an external network while preventing the transmission of in-home network signals to the external network. The device includes an entry port for external network signals, a first network port connected to the in-home network, multiple second network ports, and various components such as splitters, signal blocking devices, and signal attenuation devices. The device is configured to allow external network signals to pass through based on frequency bands while blocking in-home network signals from reaching the external network. By employing directional couplers and low-pass filters, the device effectively manages the flow of signals in different frequency bands, ensuring secure and efficient communication within the network.

Furthermore, the entry device includes features such as signal attenuation and communication devices that permit bidirectional communication of in-home network signals among the network ports while blocking the transmission of these signals to the entry port. The device's design allows for the selective passage of external network signals based on frequency bands, ensuring that only authorized signals are communicated between the networks. With additional components like amplifiers for signal amplification, the entry device provides a comprehensive solution for managing network communication effectively. Overall, the patented entry device offers a sophisticated and reliable mechanism for controlling signal flow between in-home and external networks, enhancing network security and efficiency in a variety of applications.
