“…Indoor navigation is a subject that has been studied over the years using variety of techniques and technologies (Storms, Shockley, & Raquet, 2010;Hammadi, Hebsi, Zemerly, & Ng, 2012) Gu, Lo, and Niemegeers (2009) posit that an indoor navigation system consists of a network of devices used in locating objects or people inside a building. Upon knowing where something or someone is, activities such as tracking and position determination can be done with the information (Gu et al, 2009;H.…”

“…Over the past decade, mobile phones have been used in indoor navigation research (Hammadi et al, 2012). Mobile indoor navigation involves an individual finding his/her way around within indoor spaces to arrive at a desired destination using an interactive navigation system in a mobile device (Hammadi et al, 2012).…”

“…Mobile indoor navigation involves an individual finding his/her way around within indoor spaces to arrive at a desired destination using an interactive navigation system in a mobile device (Hammadi et al, 2012). It involves the use of a mobile device, an installed navigation application in the mobile device, map of the indoor space of the building and a database to store map data.…”

“…The NFC positioning system consists of three main components, namely a passive tag, reader and database (Hammadi et al, 2012;Sakpere, Mlitwa, & Adeyeye-Oshin, 2017). While the reader, which is an NFC mobile device, reads the content of the passive tag, the database is a centralised location where indoor map data of a building is stored (Hammadi et al, 2012;Ozdenizci, Ok, Coskun, & Aydin, 2011).…”

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.
