Multi-Radio Concurrent Transmission Networks for Higher Throughput
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Concurrent Transmission (CT)-based flooding networks are limited to low data rates (e.g., 100s kbps to 2 Mbps) due to reliance on frequency demodulated radios like IEEE 802.15.4 and Bluetooth Low Energy, restricting their application to low-throughput use-cases, while high-throughput applications like audio or video transmission are unsuited for these technologies.
Innovation Solution
Implementing a multi-radio system where each host device includes multiple radios, aggregating channels to provide high throughput or redundancy through packet fragmentation and replication across orthogonal frequencies, synchronized for concurrent transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If CT flooding networks use frequency demodulated radios (IEEE 802.15.4, BLE), then reliability is improved through concurrent transmission, but data rate remains limited to 100s kbps to 2 Mbps
Solution Approach 1:
The patent segments data packets into multiple fragments and distributes them across multiple radios operating on different frequency channels. Each radio transmits a portion of the data concurrently, allowing the system to achieve high throughput while maintaining the reliability benefits of CT flooding networks. The receiving device reassembles the fragments to reconstruct the original data.
Solution Approach 2:
The patent transitions from single-radio sequential transmission to multi-radio parallel transmission by adding the frequency channel dimension. Multiple radios operate simultaneously on orthogonal frequency channels, transforming the system from one-dimensional (single channel) to multi-dimensional (multiple channels) operation, thereby achieving Wi-Fi-like throughput while preserving CT flooding reliability.
2Reliability
If multiple radios are used for packet fragmentation and replication, then throughput and reliability are improved, but device complexity increases
Solution Approach 1:
The patent implements a universal multi-radio system where each radio can perform multiple functions: transmitting data fragments, receiving data fragments, and participating in synchronization protocols. This multi-functionality reduces overall system complexity by eliminating the need for specialized hardware for each function, allowing the same radio infrastructure to handle both throughput enhancement and reliability assurance.
Solution Approach 2:
The patent merges the functions of multiple radios under a unified control framework that manages packet fragmentation, replication, and reassembly. By combining these functions into an integrated system with shared resources and coordinated operation, the patent reduces the complexity that would otherwise arise from managing separate independent radio systems.
3Use of energy by moving object
If synchronous flooding is implemented across multiple radios, then energy consumption is reduced through efficient transmission, but coordination complexity increases
Solution Approach 1:
The patent implements periodic synchronization intervals where all radios in the network align their transmission timing. Rather than requiring continuous coordination, the system uses periodic sync moments to establish time references, allowing radios to operate autonomously between intervals. This periodic approach reduces coordination complexity while maintaining the energy efficiency benefits of synchronous transmission.

AI summary
Systems, methods, and computer-readable media for synchronizing and controlling concurrent transmission-based multi-radio devices to support higher throughput or higher reliability communications in a synchronous flooding mesh network. A host device in a wireless communication network can include multiple radio devices, with each radio device part of a concurrent transmission (CT)-based flooding network configured to concurrently transmit data to one or more corresponding receiving radios with corresponding radio nodes of other devices in the wireless communication network. Data packets can either be fragmented via a packet fragmentation process or replicated via a packet replication process to prioritize either throughput or redundancy for data transmission. The host devices in the network can synchronize a time for transmitting data and distributing any of a set of orthogonal radio frequency channels for each CT flooding network in transmitting data.
