Triple Channel BLE Receiver for Medical Data Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Bluetooth Low Energy (BLE) beacons experience significant data packet loss during transmission due to their limited range and energy efficiency, leading to unreliable data transfer and reduced connection range.
Innovation Solution
A fixed triple channel receiver architecture is implemented, where each receiver is equipped with three radios that simultaneously scan and receive data across three radio channels (CH. 37, CH. 38, and CH. 39), enhancing the chances of data packet reception and reducing losses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If BLE beacons transmit data at regular intervals to conserve energy, then energy consumption is reduced, but data packet loss increases during transmission
Solution Approach 1:
The patent segments the data transmission process by dividing data into multiple packets distributed across three different radio channels (CH 37, CH 38, CH 39). Each channel independently transmits a portion of the data, allowing the system to recover from packet loss on any single channel while maintaining overall data integrity.
Solution Approach 2:
The patent adds a dimensional approach by utilizing multiple radio channels simultaneously for data transmission. Instead of relying on a single channel, the system transmits data across three channels in parallel, increasing the probability of successful reception and reducing packet loss without significantly increasing energy consumption.
2Device complexity
If BLE beacons use single receiver architecture to simplify device complexity, then device complexity is reduced, but data packet loss increases
Solution Approach 1:
The scanning function is segmented across three independent radios within the single receiver architecture. Each radio is configured to scan a specific channel (CH 37, CH 38, or CH 39), allowing the system to monitor multiple channels simultaneously without requiring multiple complete receiver units.
Solution Approach 2:
The single receiver is designed with multi-functionality by incorporating three radios that can simultaneously perform scanning and receiving operations across different channels. This universal design allows one receiver to fulfill the role of multiple specialized receivers, reducing overall device complexity while improving reliability.
3Use of energy by moving object
If BLE beacons transmit over limited range to conserve energy, then energy consumption is reduced, but connection range is restricted
Solution Approach 1:
The patent extends the effective connection range by utilizing multiple radio channels simultaneously. This dimensional approach allows the beacon to maintain reliable communication at greater distances by increasing the probability of packet reception through channel diversity, without increasing transmission power or energy consumption.
