Wireless Indoor Localization

Description

The wireless data frame has 2000 rows and 8 columns. The first 7 variables report the measurements of the Wi-Fi signal strength received from 7 Wi-Fi routers in an office location in Pittsburgh (USA). The last column indicates the class labels.

Usage

wireless

Format

A data frame containing the following columns:

• V1 Signal strength from router 1.

• V2 Signal strength from router 2.

• V3 Signal strength from router 3.

• V4 Signal strength from router 4.

• V5 Signal strength from router 5.

• V6 Signal strength from router 6.

• V7 Signal strength from router 7.

• V8 Group memberships, from 1 to 4.

Details

The Wi-Fi signal strength is measured in dBm, decibel milliwatts, which is expressed as a negative value ranging from -100 to 0. The labels correspond to 4 different rooms. In total, we have 4 groups with 500 observations each.
