1Length of stationary object
If Bluetooth or Wi-Fi modules are used for data transmission, then point-to-point data sharing can be realized in local area network, but the transmission distance is limited and long-distance data sharing cannot be achieved
Solution Approach 1:
The communication module dynamically switches between bypass mode and operation mode based on transmission distance requirements. In bypass mode, it provides stable point-to-point communication for short distances. In operation mode, it enables enhanced signal transmission for long distances by activating additional signal processing pathways and power management configurations.
Solution Approach 2:
The system changes transmission parameters including power output levels, modulation schemes, and frequency hopping patterns based on detected distance requirements. When long-distance transmission is needed, the system adjusts parameters to optimize signal propagation while maintaining data integrity through adaptive error correction.
2Length of stationary object
If transmission power is increased to extend transmission distance, then long-distance data sharing becomes possible, but energy consumption increases
Solution Approach 1:
The communication module dynamically adjusts power output based on real-time transmission requirements. Instead of maintaining high power continuously, the system switches to high-power mode only when long-distance transmission is detected needed, and returns to low-power mode for normal operations, thereby extending transmission distance when necessary while minimizing overall energy consumption.
Solution Approach 2:
The system employs periodic signal transmission with intelligent power cycling. Transmission bursts are timed and powered according to actual data transfer needs, with idle periods allowing power reduction. This periodic action pattern enables long-distance capability when required while averaging lower energy consumption over time.
