Solution Overview
Problem
Current handover mechanisms in BLE communication technology restrict simultaneous communication with multiple centrals, as they are designed for star-connected topologies, preventing simultaneous BLE communication with multiple peripherals.
Innovation Solution
A communication apparatus equipped with both BLE and wireless LAN communication units, allowing it to operate as a peripheral and establish wireless LAN connections with multiple centrals by switching between BLE and wireless LAN communication modes, enabling simultaneous communication with multiple external apparatuses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If BLE communication technology is used with star topology, then power consumption is reduced, but the ability to simultaneously communicate with multiple centrals is lost
Solution Approach 1:
The communication apparatus dynamically switches between BLE and wireless LAN communication modes based on the number of connected external apparatuses. When multiple centrals need simultaneous connection, the system transitions from BLE to wireless LAN, enabling adaptive communication capability that matches the dynamic connection requirements.
Solution Approach 2:
The system changes the communication parameter (communication mode) from BLE to wireless LAN when the connection scenario requires simultaneous communication with multiple centrals. This parameter change allows the peripheral to overcome the topological constraints of BLE and support multi-central connections.
2Ease of operation
If handover mechanism is used for BLE communication, then connection switching is simplified, but simultaneous communication with multiple centrals is prevented
Solution Approach 1:
The communication system is segmented into two distinct communication modes: BLE for single-central connections and wireless LAN for multi-central connections. This segmentation allows each mode to operate optimally within its designed capability, with the control unit managing transitions between them based on connection requirements.
Solution Approach 2:
The control unit acts as an intermediary that manages the transition between BLE and wireless LAN communication modes. It monitors connection requirements and initiates handover processes, enabling the system to switch between communication technologies seamlessly based on the number of connected centrals.
3Adaptability or versatility
If a single peripheral connects to multiple centrals in BLE, then device compatibility is improved, but communication bandwidth is limited
Solution Approach 1:
The communication apparatus is designed with multi-functionality, supporting both BLE and wireless LAN communication modes. This universality allows the same peripheral device to serve single-central scenarios with BLE (maintaining compatibility) and multi-central scenarios with wireless LAN (providing enhanced bandwidth).
