The data were collected in two different scenarios with some set-ups in each one. give a multi-scenario BLE database for fingerprinting positioning.

Moreover, additional resources like the environmental description and examples on how to use the data for proximity and positioning applications are also provided along with the database. These data provide information to test the effects of different configurations within the same environment, the effects of diverse devices and the effects of using more than one signal (slot) for each transmitter device. All measurements were correctly labeled with its area identification (for proximity applications) and coordinates in a local positioning system (for positioning applications). We used three different deployment configurations to assess the robustness of the system and the influence of its characteristics. The experiments were carried out in the buildings of the Faculty of Science at the University of Extremadura (UEx) in its campus in Badajoz (Spain). The database is composed of raw measurements from different smartphones for the development of indoor positioning and proximity techniques. The primary contribution of this work is to introduce to the research community a new BLE RSSI database. In this situation, many researchers have concentrated on the techniques and algorithms used to increase the accuracy and robustness of this system. The BLE has already been used successfully for LBS in indoor environments such as airports and museums.

BLE transmitters, known as beacons, are small encapsulated devices that can work with a battery for more than a year, broadcasting BLE signals with specific pieces of information.

it was born as part of the Bluetooth 4.0 core specification and works in the same Industrial Scientific and Medical (ISM) band of 2.4 GHz where Wi-Fi, Zig-Bee, and classic Bluetooth works. The closest alternative is Bluetooth Low Energy (BLE), a radio frequency communication protocol designed for short and energy-saving communications in the context of the Internet Of Things (IoT). ĭespite its implementations, Wi-Fi scanning process is being restricted in many operating systems which might decrease or restrict the amount of information available for positioning. Fingerprinting or scene analysis positioning compares real-time with previous measurements in known positions. Proximity applications use the position of the emitter with the highest RSSI, meanwhile ranging methods model signal propagation between transmitter and receiver to estimate the distance between them. RSSI-positioning can be used in three different ways: proximity, ranging, and fingerprinting. The received signal strength indicator (RSSI) is very popular in smartphone applications since no additional hardware is required to measure it. Other types of techniques, such as the angle of arrival (AoA), is used to estimate the orientation of the signal. Similarly, the time differential of arrival (TDoA) measures the time difference between signals arrival to an anchor. Some of the best-known techniques are the time of flight (ToA), which is the travel time of a signal from the transmitter to a receiver. In addition to the diversity of technologies, several positioning techniques have been used for the development of these systems. A special group of technologies are those that are embedded in most off-the-shelf smartphones and hence do not need extra components on the receiver, like BLE and Wi-Fi. Some of these, as the ultrasound and UWB, can provide centimeter precision, but need special hardware, increasing the price. Among those are Ultrasound, Visible Light Communication (VLC) and radio-frequency networks, such as Radio-Frequency Identification (RFID), ZigBee, Wi-Fi, Bluetooth Low Energy (BLE) and Ultra Wide Band (UWB). Many technologies have been tested to build Local Positioning Systems (LPS).

Withal, 87 % of the daily time is spent on these environments, and therefore, an alternative is needed to provide position estimations for LBS in indoor areas. Despite its world-wide range, GNSS loses accuracy in complex environments, such as indoor scenarios, because of the physical barriers that the signal must go through. The most extended technology for LBS is the Global Navigation Satellite System (GNSS), which can provide position accuracy within the order of meters, high accuracy may be obtained with, for instance, Precise Point Positioning and augmentation services. This kind of developments, known as Location-Based Services (LBSs), has grown exponentially in recent years because of its integration with smartphone devices.

Among others, wireless networks can be used as a backing for applications that serve a certain task according to the user’s position. The quick growth of wireless communication networks has fostered new uses beyond simple information exchange.
