For example, smartphones generally show worse WiFi performance than other WiFi devices (e. g., laptops and tablets) because smartphones suffer from additional signal loss due to hand-grips and the low antenna gains of their embedded antennas.
However, the multi-path fading of WiFi signals causes time-varying received signal strengths of WiFi signals, which leads to poor accuracy of WiFi localization.
Based on the measurement results from our real-world deployments, we made three main observations: 1) in general, higher AP density improves WiFi performance; 2) over-dense deployment with unnecessarily high transmission power can worsen WiFi performance.
Corresponding, good signal strength will makes WiFi energy consumption decreased.
For home and work environments, aggressive WiFi scans can significantly improve the speed at which mobile nodes join the WiFi network.
Our results supported that the WiFi-aided MM algorithm provided more reliable solutions than both WiFi and MM in the areas that have poor WiFi signal distribution or indistinctive magnetic-gradient features.
The proposed algorithm provided more reliable solutions than both PDR/WiFi and PDR/MM, especially in areas with poor WiFi signal distribution or indistinctive magnetic features.

We believe the root cause of lesser WiFi utilization can be traced to the WiFi being optimized for laptop WiFi reception rather than the more constrained smartphone WiFi reception.
WiFi positioning techniques based on signal angle-of-arrival measurements have good accuracy and are promising.
In fact, the more friendly the building to WiFi signal, the more efficient the 802.11 based wireless infrastructure.
