In this paper, an indoor positioning method, namely LiPro, is proposed for handheld devices such as smartphones. Based on an empirical light intensity model, we propose a rotating multi-face positioning method that enables a receiver to locate itself in ill-conditioned scenarios which would otherwise make the traditional multilateration impossible-for example when less than three LED lamps are visible to the receiver. In this method, the user manually performs three rotations of the receiver around three orthogonal axes, in a manner similar to the calibration process of a compass. During this process, the receiver continuously collects RSS and magnetic field strength, which are then used to solve for the receiver's position. LiPro can work with a single source of light, making it a more cost-effective and less demanding than previous approaches. Our experiments show that LiPro achieves a median error of 0.59 m in a corridor with linearly deployed LEDs, and 0.45 m in an office. Moreover, LiPro is shown to be robust against interference from ambient light sources.

“…Many VLC-based indoor positioning mechanisms have been presented [11,12]; however, such mechanisms are only designed for indoor accurate positioning, but not for communication simultaneously. In these mechanisms the LED lamps in one room should send at least three different groups of signals to assist the user terminals for localization, but in our network, all the LED lamps in the same room are broadcasting the same information to the users within this room, so these positioning mechanisms are not suitable to be directly deployed in our network.…”

Visible light communication (VLC) is considered to be an attractive scheme to realize the broadband wireless communication for an indoor environment. We present a room division multiplexing (RDM) mechanism for an indoor multi-room VLC network, which utilizes the spatial position of the LED lamp in different rooms as a novel dimension of network resource for multiplexing, and thus the network capacity is increased. In such a network, the service interruption caused by user cross-room movement is an important problem, and we propose a double-area-positioning based cross-room switch solution. An experimental platform demonstrates the RDM-deployed VLC network, and validates the performance of the presented switch mechanism.

“…The system does not require angular measurements nor received signal strength. In addition, the study of Zhou, Kavehrad, and Deng (2012) used the Lambertian equation group to determine the distance between transmitter and receiver, and estimate the position of the receiver in 2D and 3D. The system used the time division multiplexing (TDM) technique and OOK modulation without applying lateration.…”

The research and use of positioning and navigation technologies outdoors has seen a steady and exponential growth. Based on this success, there have been attempts to implement these technologies indoors, leading to numerous studies. Most of the algorithms, techniques and technologies used have been implemented outdoors. However, how they fare indoors is different altogether. Thus, several technologies have been proposed and implemented to improve positioning and navigation indoors. Among them are Infrared (IR), Ultrasound, Audible Sound, Magnetic, Optical and Vision, Radio Frequency (RF), Visible Light, Pedestrian Dead Reckoning (PDR)/Inertial Navigation System (INS) and Hybrid. The RF technologies include Bluetooth, Ultra-wideband (UWB), Wireless Sensor Network (WSN), Wireless Local Area Network (WLAN), Radio-Frequency Identification (RFID) and Near Field Communication (NFC). In addition, positioning techniques applied in indoor positioning systems include the signal properties and positioning algorithms. The prevalent signal properties are Angle of Arrival (AOA), Time of Arrival (TOA), Time Difference of Arrival (TDOA) and Received Signal Strength Indication (RSSI), while the positioning algorithms are Triangulation, Trilateration, Proximity and Scene Analysis/ Fingerprinting. This paper presents a state-of-the-art survey of indoor positioning and navigation systems and technologies, and their use in various scenarios. It analyses distinct positioning technology metrics such as accuracy, complexity, cost, privacy, scalability and usability. This paper has profound implications for future studies of positioning and navigation.
