Nested Data Packets for Multi-Device Wireless Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multi-device communication systems face challenges in efficiently transmitting data packets to multiple devices using traditional methods, which often result in packet errors and inefficient data delivery due to lack of multi-access addressing capabilities.
Innovation Solution
The method involves generating nested data packets with unique access addresses and payloads, allowing multiple devices to detect and extract their intended payloads by using a synchronization sequence and Hamming distance calculations, enabling efficient communication across short-range wireless networks like Bluetooth and NFC.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional data packet transmission methods are used, then the communication system is simple, but packet errors increase and data delivery efficiency decreases
Solution Approach 1:
The patent implements nested data packets where multiple data packets are contained within a single outer packet structure. Each inner packet has its own access address and payload, allowing multiple devices to receive different data through a single transmission. This nesting structure resolves the contradiction by improving data delivery efficiency to multiple devices without requiring separate transmission packets for each device.
Solution Approach 2:
The patent segments the data transmission process by dividing the payload into multiple independent inner packets, each addressed to specific devices. This segmentation allows the system to maintain simplicity at the transmission level while achieving reliable delivery to multiple devices through structured packet division and individual addressing.
2Loss of time
If multiple data packets are transmitted separately to multiple devices, then each device receives accurate data, but transmission time and bandwidth consumption increase
Solution Approach 1:
The patent merges multiple separate data packets into a single outer packet that contains multiple inner packets. This combining approach transmits data to multiple devices simultaneously in one transmission event, reducing total transmission time and bandwidth consumption while maintaining data accuracy through individual inner packet addressing and payload separation.
3Reliability
If access addresses are not uniquely assigned to devices, then the system is simpler to operate, but packet errors increase due to address conflicts
Solution Approach 1:
The patent applies local quality by assigning unique access addresses to specific inner packets rather than requiring unique addresses for all packets system-wide. Each inner packet has a dedicated access address that is unique within that packet's context, allowing reliable device identification without system-wide address conflicts. This localized addressing reduces packet errors while simplifying the overall address management.

AI summary
Systems and methods for multi-device communication are disclosed herein. An example method includes generating a nested data packet including a first access address and a first payload, the first payload including a first target payload and a first payload nesting section, the first access address being assigned to a first device, a second access address and a second payload placed into the first payload nesting section, and transmitting the nested data packet to the first device and the second device.
