Generation of Channel Access Patterns for Uncoordinated Networks

Simple SummaryContent extracted from patent full text and abstract with AI.

This patent describes a system and method for generating and managing channel access patterns for wireless communication networks that operate independently and share the same frequency band (such as the ISM bands). It employs pseudo-random and network-specific algorithms to determine when and on which frequencies each network device transmits, reducing interference between co-located, uncoordinated networks. The invention enables reliable data transfer by ensuring each network uses different frequency-time patterns without needing mutual coordination or centralized management.

Use CasesContent extracted from patent full text and abstract with AI.

• Industrial IoT deployments with many independently operated wireless sensor networks using shared frequency bands.
• Smart home and building automation systems with multiple wireless devices/networks operating in proximity.
• Wireless medical devices in hospitals where networks must coexist without direct coordination.
• Deployments in dense urban areas where multiple independent wireless networks (such as smart city sensors) operate in shared spectrum.
• Temporary event setups (e.g., trade shows, concerts) with independent wireless systems requiring minimal interference.

BenefitsContent extracted from patent full text and abstract with AI.

• Significantly reduces mutual interference between independent wireless networks using the same frequency band.
• Allows for high network density and scalability without centralized coordination.
• Improves reliability and data transfer success even in crowded spectrum environments.
• Minimizes signaling overhead and network configuration effort for new or existing devices.
• Supports energy efficiency for battery-operated devices by enabling predictable, low-collision communication schedules.
• Facilitates dynamic adaptation to changing network loads or frequency domain interference.
• Enhances overall quality of service for end-users and devices in shared-spectrum environments.
