Accurate GSM Indoor Localization
Accurate indoor localization has long been an objective of the ubiquitous computing research community, and numerous indoor localization solutions based on 802.11, Bluetooth, ultrasound and infrared technologies have been proposed. This paper presents the first accurate GSM indoor localization system that achieves median accuracy of 5 meters in large multi-floor buildings. The key idea that mak...

Accurate indoor localization has long been an objective of the ubiquitous computing research community, and numerous indoor localization solutions based on 802.11, Bluetooth, ultrasound and infrared technologies have been proposed. This paper presents the first accurate GSM indoor localization system that achieves median within floor accuracy of 4 m in large buildings and is able to identify th...
متن کاملAn experimental study of indoor RSS-based RF fingerprinting localization using GSM and Wi-Fi signals
Localization of mobile users in indoor environments has many practical applications in daily life. In this paper, we study the performance of the received signal strength (RSS)-based radio frequency (RF) fingerprinting localization method in a shopping mall environment considering both calibration and practical measurement cases. In the calibration case, the test data for the RSS fingerprinting...
متن کاملA GSM Based Localization Scheme
Wireless localization has been an active research area over the last decade due to its endless applications. In this paper, we investigate received signal strength (RSS) based estimation of a mobile station’s location, through monitoring the RSS at multiple reference software defined radio (SDR) receivers. Uplink transmission power of the mobile stations and path loss exponent are assumed to be...
متن کاملBluetooth Indoor Localization System
We present a Bluetooth indoor localization system, which is intended to have an accuracy of ±1 meter. The major advantage compared to all disclosed systems is the ability to locate any mobile Bluetooth device without additional hardware in the mobile and without any changes in its software. The basic idea of the system is the measurement of time differences of arrival of a signal sent by the mo...
