Lambda:4 Innovative R&D Rönne Reimann, Arne Bestmann, Mirjam Ernst Highly accurate distance measurement with radio wave methods for low cost localization _v1.4
Overview Lambda:4 Technical Explanation Prototypes and Applications Performance Future Aspects Time for Questions
Lambda:4 R&D Company est. 2004, Hamburg, Germany History: 2007 – PCB stack with bearing function 2010 – pilot projects „avalanche rescue“ and „locating missed people“ 2011 – hand-held prototype with bearing, distance measurement, barometric sensor for crew locate pilot projects with fire brigades, integration of inertial sensor modules, first tests in AAL environments 2013 – easyPoint – Indoor positioning & navigation
Technical explanation Distance measurement at 2.4 GHz frequency Low cost chips (e.g. TI CC25) Many protocols using 2.4 GHz Already integrated in mobile devices Bearing also possible High-resolution spectral method, like MUSIC Very good differentiation of signal parts Highly accurate distance measurement
Prototypes for first showcase easyPoint EP 20 EP 100 Rex User Interface on Toughbook/Smartphone/Tablet etc. Rex
Prototypes for first showcase Low cost Simple components Simple startup procedure Plug & Go installation App able to use existing maps Open protocol for application development Easy as hanging up pictures…
Manifold Applications Flexible components make use in manifold applications possible Logistics Lifestyle – Shopping malls, supermarkets, airports … Ambient Assisted Living (AAL) – Support for Elderly, Blind, Disabled People Search and Rescue – CrewLocate, E911, …
Application Airport
Technical performance floor plan showing route covered and route points (for example „M20“)
Technical performance Comparison of FFT and HiRes, 224 distance measurements in the range between 0 and 3 meter Little benefit of HiRes methods in short range Comparison of FFT and HiRes, 1377 distance measurements in the range between 7 and 11 meter Big benefit of HiRes methods in long range
Technical performance Test in office building (270 m²) with 4 EP 20 Root mean square deviation between 0.7 and 1.1 m for each EP
Future Aspects Integration into 2.4 GHz chips and protocols e.g. Bluetooth, WiFi and ZigBee Little step, big benefit! Discussion with standardisation committees (BT SIG, In-Location Alliance,...)
…Time for your Questions… Thank you for your attention!
