This is the dataset of received signal strength indicator (RSSI) from Wi-Fi routers in different environments.

RSSI was collected by a person holding an Android tablet within one hour 

in S301, Graduate School of Informatic Science (Main Building), Kobe University, Japan.

We collected the RSSI between the terminal and Wi-Fi routers 

per second 30 times at 20 reference points with doors open. 

Then, we collected RSSI data again with doors closed. 

The distance between reference points is greater than or equal to 2 m.
