BLE Terminal Data Redundancy for Expanded Range
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional Bluetooth Low Energy (BLE) technology is limited by the size of advertisement packets, restricting the ability to transmit arbitrary messages and thus limiting its application range.
Innovation Solution
A terminal apparatus that receives data elements from an information transmission apparatus, makes the data redundant using a predetermined method, divides it into N data elements, and transmits these elements as short-range communication signals, allowing reproduction from any arbitrary combination of m data elements, thereby expanding the communication range.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If advertisement packet size is increased to transmit arbitrary messages, then the application range is improved, but the compatibility with conventional BLE systems deteriorates
Solution Approach 1:
The transmission target data is divided into multiple data elements, where the number of data elements is equal to or greater than 2. Each data element is then transmitted as a separate advertisement packet, allowing large data to be transmitted through multiple small packets that are compatible with conventional BLE systems.
Solution Approach 2:
The patent transitions from transmitting single large packets to transmitting multiple small packets across different time dimensions. Terminal apparatuses receive and combine multiple data elements from sequential advertisement packets, effectively expanding the transmission capacity without increasing individual packet size.
2Area of stationary object
If data is divided into multiple elements for transmission, then the communication range is expanded, but the data reconstruction complexity increases
Solution Approach 1:
The terminal apparatus is pre-configured with the capability to receive and combine multiple data elements. The system prepares the data reconstruction mechanism in advance, so when advertisement packets are received, the terminal can immediately process and combine the data elements without complex real-time computation.
Solution Approach 2:
The terminal apparatus autonomously performs the data combination process using the received data elements. The system self-manages the reconstruction of transmission target data from the multiple data elements without requiring external intervention or complex coordination protocols.

AI summary
An information transmission apparatus 2 makes transmission objective data redundant using a predetermined method, divides the redundant data into N (N≥2) data elements, the transmission objective data being reproducible on the basis of any arbitrary combination of m (m<N) or more data elements, and sequentially transmits short-range communication signals respectively including the N data elements obtained by the division. A terminal apparatus 3 which receives the data elements tries to reproduce the data using the received data elements, and transmits short-range communication signals including the received data elements.
