To connect to IPSServer, press the SW2 button on CY8CKIT-042 BLE to switc In this article, an efficient 3-D position system is proposed. The proposed system uses Bluetooth low-energy (BLE) beacons to estimate the distance and calculate 3-D coordinates based on 3-D triangulation. BLE 4,5 is the general term applied to all two-way, near-field wireless communication technologies and products. It was originally based on the Bluetooth 4.0 Core. However, unlike existing Bluetooth technologies, BLE is a newly defined technology to reduce the transmission. Bluetooth ® technology is the standard for creating proximity solutions used for point of interest (PoI) information and item finding as well as positioning systems such as real-time locating systems (RTLS) for asset tracking and indoor positioning systems (IPS) for wayfinding Indoor positioning algorithms based on Bluetooth can be mainly divided into two categories: geometric methods and the algorithms based on RSSI. This paper is based on the RSSI methods. The RSSI method is mainly to acquire Bluetooth access point signal strength (RSS) and determines the positioning area [ 14, 15 ]
This study investigated the impact of Bluetooth Low Energy devices in advertising/beaconing mode on fingerprint-based indoor positioning schemes. Early experimentation demonstrated that the low bandwidth of BLE signals compared to WiFi is the cause of significant measurement error when coupled with the use of three BLE advertising channels. The physics underlying this behaviour is verified in simulation. A multipath mitigation scheme is proposed and tested. It is determined that the optimal. Consequently, attention to indoor positioning system (IPS) has been increasing rapidly as an alternative to GPS for such locations. Various wireless technologies such as Bluetooth low energy (BLE), Wi-Fi, visible light communication (VLC), and ultra-wideband (UWB) have been used in IPS. Because BLE is widely supported by mobile devices and is designed for short-range wireless transmissions with low energy consumption and low cost, it seems more promising than other wireless technologies In recent years, researchers began to study using Bluetooth 4.0 and Bluetooth Low Energy (BLE) for indoor positioning purposes. In general, positioning techniques based on received signal strength indicator (RSSI), such as signal propagation and fingerprint, are commonly used in wireless/mobile networks. These techniques have certain limitations and tradeoff in terms of accuracy, ease of implementation and practical application/deployment. For example, both methods require a training process. In this paper we present XtremeLoc, a low-cost indoor positioning system designed to work in situations where GPS is not a valid alternative. XtremeLoc relies on the use of portable, low-cost, Bluetooth Low Energy beacons using the iBeacon protocol Bluetooth based indoor positioning technologies are attracting increasing attention. Instead of using a Wi- Fi router , Bluetooth 4 based localization systems locate the position of a mobile device with reference to low-energy Bluetooth beacon routers in an indoor area. Compared with Wi-Fi, BLE devices have advantages of lower power consumption, lower costs and a smaller size . Newer.
