Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In multi-dwelling units, establishing connectivity between home area networks and metering devices can be challenging due to distance and interference from impedance sources, leading to issues with data transmission and security in current communication infrastructure.
Innovation Solution
Implementing an in-premises management device within the dwelling, equipped with a network interface, processor, and transceiver, which establishes a paired communication link with a remote computing device to manage the home area network, reducing interference and enhancing security by minimizing data traffic and crosstalk between dwellings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If a metering device is physically attached to the monitored building, then connectivity range is sufficient for single-dwelling homes, but the device cannot be remotely installed in multi-dwelling units
Solution Approach 1:
The system divides the monitoring function into two separate components: a management device installed remotely (e.g., in a utility room or hallway) and a network interface device installed within the dwelling. This segmentation allows the metering device to be located away from the monitored premises while maintaining connectivity through the HAN network.
Solution Approach 2:
The patent introduces a management device as an intermediary component that bridges the gap between the remotely located metering device and the internal HAN devices. The management device receives commands from the metering device and relays them to the appropriate terminal devices within the dwelling, enabling remote installation while maintaining full functionality.
2Length of stationary object
If data traffic is transmitted over long distances through building structures, then connectivity is achieved, but interference from impedance sources increases
Solution Approach 1:
The communication path is segmented into two parts: a wired portion within the dwelling (avoiding external interference) and a wireless or separate wired portion for remote communication. This segmentation allows data to be transmitted locally without exposure to building structure interference, while still enabling remote management.
Solution Approach 2:
The management device acts as an intermediary that receives data from the HAN network locally and transmits it to the remote metering device through a separate communication channel. This intermediary approach isolates the HAN traffic from impedance sources in the building structure while maintaining connectivity.
3Device complexity
If a centralized metering device is used for multi-dwelling units, then installation is simplified, but security and data transmission reliability decrease
Solution Approach 1:
The system segments the monitoring architecture so that each dwelling has its own network interface device that processes and secures data locally before transmission. This segmentation maintains installation simplicity while improving security by isolating data paths between dwellings and preventing cross-contamination of signals.
Solution Approach 2:
The management device serves as a secure intermediary that authenticates and manages communication between the HAN and the remote metering device. It implements security protocols and data validation, ensuring that data transmission remains secure and reliable even though the metering device is remotely located.

AI summary
Systems and methods are disclosed for providing in-premises management of home area networks. An example management includes a network interface device, a processor in communication with the network interface device, and a transceiver device in communication with the processor. The network interface device can establish a paired communication link with a computing device that is in communication with a head-end system. The processor can receive a command originating from the head-end system and communicated to the management device from the computing device via the paired communication link. The processor can identify a terminal device of the home area network that can perform a function in response to the command. The processor can generate a message for the terminal device including the command. The transceiver device can transmit the message from the processor to the terminal device via a wireless communication link of the home area network.
