1Measurement precision
If camera-based SLAM techniques are used to generate maps, then mapping accuracy is improved, but computational cost and power consumption increase significantly
Solution Approach 1:
The patent extracts and utilizes pre-existing wireless signal infrastructure (Wi-Fi, Bluetooth, cellular towers) as environmental features for mapping, removing the need for power-intensive camera-based SLAM processing while maintaining mapping functionality through signal strength-based position estimation
Solution Approach 2:
The patent replaces the mechanical/optical system of cameras and image processing with an electromagnetic field-based system using wireless signal reception and triangulation, significantly reducing computational burden and power consumption while achieving comparable positioning accuracy
2Reliability
If multiple sensors are used for environment detection, then mapping reliability is improved, but device complexity and cost increase
Solution Approach 1:
The patent makes the wireless communication module serve multiple functions: both data transmission and environmental mapping, eliminating the need for dedicated sensors and reducing device complexity while maintaining mapping reliability through multi-signal-type triangulation
Solution Approach 2:
The patent enables mapping functionality to be performed using the device's existing wireless communication capabilities without requiring additional dedicated hardware, allowing the device to map environments using resources already present in the system
