1. Lambda:4 Innovative R&D Rönne Reimann, Arne Bestmann, Mirjam Ernst Highly accurate distance measurement with radio wave methods for low cost localization 2013-03-19_v1.4

2. Overview Lambda:4 Technical Explanation Prototypes and Applications Performance Future Aspects Time for Questions

3. 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 2012 - pilot projects with fire brigades, integration of inertial sensor modules, first tests in AAL environments 2013 – easyPoint – Indoor positioning & navigation

4. 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

5. Prototypes for first showcase easyPoint EP 20 EP 100 Rex User Interface on Toughbook/Smartphone/Tablet etc. Rex

6. 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…

7. 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, …

8. Application Airport

9. Technical performance floor plan showing route covered and route points (for example „M20“)

10. 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

11. 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

12. 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,...)

13. …Time for your Questions… Thank you for your attention!
