However, a practical floor localization system should consider the absence of infrastructure, the pretrained database and the influence of complex environment. Wi-Fi enabled system and barometer-based system are two well-known systems in floor localization. And finally, the top 250 features have been selected for the XGBoost Classifier to build an efficient model that has given accuracy and f1 score of 79.11% and 79.39% respectively on the validation dataset.įloor localization plays a crucial role in multi-storey indoor positioning systems. have been trained among which the XGBoost Classifier model has performed the best. Using 1350 features, different models like Extra Trees Classifier, Random Forest Classifier, XGBoost Classifier, etc. Various features have been extracted from the frequency and time domain and diverse windowing techniques have been implemented. We, team “Guerrilla”, have used the location data to extract different features like distance, velocity, acceleration, and hand-picked certain information from the satellite, WiFi, and cell tower data. Though the dataset has provided good location data, the main challenge has been how to use the variable number of data from satellite, WiFi, and cell tower information. This puts the roaming decision in your phone's hands instead of APs rejecting it when the signal is too low.Sussex-Huawei Locomotion-Transportation (SHL) recognition challenge, the fourth edition of the challenge provides an opportunity to recognize 8 modes of locomotion and transportation (activities) from radio data, including GPS reception, GPS location, WiFi reception, and GSM cell tower scans in a user-independent manner. If your clients signal is degraded enough that it can't maintain the speed you specify, it should roam to a better AP on its own.

In a home situation, you may find it more useful to set a minimum speed.

That may be the same one or a different one, but if it's not a strong enough signal both APs may reject the phone leaving it without a working Internet connection. Then the AP will say 'your signal is too week go find another AP.' Your phone will then scan and connect to the AP with the best signal. This means your phone can associate with one AP. Remember that if you set the RSSI too high (closer to 0), you can end up in a situation where both of your APs keep disassociating with your client. Try it for a while and see if devices are roaming well. Use WiFiman to measure signal strength in each band.
