Centimeter positioning accuracy in modern wireless cellular networks – wish or reality?

Abstract

The paper explores the evolution of wireless positioning technologies across cellular network generations, emphasizing the advancements from 2G to the current 5G and anticipating the upcoming 6G around 2030. Positioning methods, such as Theta-Theta, Rho-Rho, and Hyperbolic, are discussed for both two-dimensional and three-dimensional applications, revealing the complexities and improvements in accuracy. The limitations of methods like Theta-Theta are addressed, and enhancements through multi-antenna systems are explored. The role of Ultra-Wideband (UWB) technology in overcoming the limitations of Received Signal Strength Measurement (RSSI) for accurate distance measurements is highlighted. The abstract underscores the continuous strive for precision in location determination, catering to diverse applications from industrial automation to sports and rehabilitation.
