“…In addition, there has been work on estimating position by measuring the Direction Of Arrival (DOA) at the MD or AP [17]. In our view, rotating the MD antennae, either mechanically or electronically, by beamsteering an array, is not practical due to device size considerations.…”

“…The Global Positioning System (GPS) has limited ability to function properly indoors. Sensors that can triangulate which room an individual is in are commonplace (whether based on RSSI wifi [17][18] or UWB radio [19]), but they are not accurate enough to measure gait velocity or to detect specific susceptibilities, such as likelihood of a fall or a loss in balance. Radio-frequency identification (RFID) tags can be placed on individuals' bodies, but these only register location when the tag is less than 1 meter from a fixed RFID reader (e.g., when a person enters a room) [20] Note: This is not the official version of the paper.…”

Abstract-Helping elderly people to live independently within their homes for as long as possible, before transitioning to higher levels of care, can significantly reduce healthcare expenditures. However, achieving this vision requires continuous monitoring of the condition of elderly adults within their homes. In particular, activity, gait velocity, movement, and location of elderly adults are critical biomarkers for healthy aging. We present a prototype integrating a wearable location-tracking sensor with back-end cloud-based data processing, thereby enabling real-time tracking and analysis of a large number of people simultaneously. The resulting vertically-integrated prototype provides a basic infrastructure for future work, including new products and services that offer real-time monitoring and early disease diagnosis to help elderly people live independently for as long as possible.

“…At the same time indoor robot navigation and positioning, production management and other fields also have a significant demand for high-precision navigation and position technologies [6][7]. But existing wireless technologies such as ultra wide-band (UWB) and wireless fidelity (Wi-Fi) could not meet the urgent needs because of spectrum resource, transmit power and other bottleneck problems [8][9][10][11][12]. New technical and theoretical solutions are needed urgently.…”
