Selective Broadcast Receiver Design for Fine-Grained Sectorization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing telecommunications networks struggle to simultaneously broadcast messages to massive quantities of receivers while ensuring fine sectorization and selectivity, particularly in the context of electrical network management, as conventional cellular radio and digital radio networks are not suited for this purpose, and Low-Power Wide-Area networks are not designed for continuous active reception by numerous objects.
Innovation Solution
A device with digital processing capabilities and interfaces for receiving configuration and broadcast data, using point-to-point links and broadcast data, and selectively applying received data based on configuration and transmitter identifiers, allowing selective data reception by a subset of receivers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional cellular radio networks are used to address specific terminals, then point-to-point communication is achieved, but the ability to simultaneously broadcast messages to massive quantities of receivers is insufficient
Solution Approach 1:
The receiving device is designed to support multiple communication modes (broadcast and unicast) within a single device architecture. The device can function both as a broadcast receiver for massive quantities of receivers and as a point-to-point terminal, eliminating the need for separate specialized devices for each communication mode.
2Productivity
If digital radio and television content streaming networks are used for simultaneous broadcasting, then massive quantities of receivers can be addressed, but the ability to select specific broadcast areas is too large to meet finer sectorization needs
Solution Approach 1:
The system enables different receiving devices to have different local characteristics through configuration data items. Each device can be configured with specific identifiers, geographic locations, or sector assignments that allow it to selectively respond to broadcasts intended for its specific local area or sector, achieving fine-grained sectorization across the broadcast network.
Solution Approach 2:
Configuration data items are pre-loaded into receiving devices before broadcasting occurs. These configuration data items contain information about which transmitters or sectors the device should respond to, allowing devices to immediately filter and selectively process broadcast messages without requiring real-time analysis, thus achieving precise sectorization.
3Use of energy by moving object
If Low-Power Wide-Area networks are used to individually address autonomously powered connected objects, then power consumption is reduced, but the ability to facilitate simultaneous broadcasting to large numbers of objects with continuous active reception is insufficient
Solution Approach 1:
Instead of requiring continuous active reception, the system uses periodic broadcasting where transmitters send broadcast messages at specific intervals. Receivers can enter low-power states between broadcasts and only activate to receive and process broadcast messages when needed, significantly reducing power consumption while maintaining broadcasting efficiency.
Solution Approach 2:
The receiving device autonomously determines whether to process a broadcast message by evaluating configuration data items against the received broadcast data. This self-service mechanism eliminates the need for continuous network control or handshaking protocols, allowing receivers to operate independently with minimal power consumption while still achieving efficient selective broadcasting.
4Ease of manufacture
If powerline communications solutions are used, then existing electrical infrastructure is utilized, but the same problems and limitations as radio communications solutions persist
Solution Approach 1:
The system is designed to work with multiple communication modalities including both radio and powerline communications. The receiving device can be configured to accept broadcast messages through either medium, allowing the system to leverage existing electrical infrastructure via powerline communications while maintaining the same selective broadcasting capabilities that would exist in radio-based systems.
