Advantage of Non-Periodic Leaky Coaxial Cable Structures for Indoor Positioning

Radiating cables (LCXs) are well established for indoor coverage and are applied for surveillance sensors. An answer to the upcoming need of low-cost indoor positioning was given by the WIPoS approach. This indoor navigation system is using radiating cables with RF fingerprinting based on power level evaluation. State-of-the-art LCXs are mainly designed for broadband indoor coverage. But different cable properties are required for indoor navigation purposes. In this paper the research results of LCX-types designed for indoor positioning are presented and discussed. Existing standard LCX-types are compared with specially designed periodic and non-periodic structures. The WIPoS research project aims at improving the indoor positioning resolution while maintaining the coverage properties.
