Test Environments: old and new offices of SRC from three to five BS one beacon up to three tags staying and movement tags E-LPS Test Beds

E-LPS Test Results Current Results: all of E-LPS parameters meet the Development Plan specification except accuracy accuracy of positioning is satisfactory, but not fully meet the Development Plan specification requirements - less than 2 meter with three sigma confidence interval, specification requirements - less than 2 meter with three sigma confidence interval, confidence interval is less confidence interval is less test (experiments) statistics is not fully representative – more experiments are needed needed Reason why: improvements of E-LPS algorithms is not enough – additional corrections of algorithms and SW are needed based on a lot of experiments Dedication: continuation of tests, defining performance and limits of the system, algorithms and SW improvements, defining the system marketplace

E-LPS Development Project

E-LPS Devices Delivering & Testing (preliminary) Time Plan UWB-ID To the end of assembled and tested all HW - continue E-LPS testing and SW improving To the end of February, 2005 SRC – continue E-LPS testing and SW improving, create new version of BS and LPS Monitor SW, - sent E-LPS Development Project Final report to S1 Corporation - continue the Custom clearance procedure for E-LPS prototypes (procedure already started, the Custom require addition expertise(!) for possibility of export), - preparing yourself for business trip to Korea S1 Corporation (suggestion) - create support engineering group, - self-study E-LPS Final Report - test E-LPS in real environment in S1 Corporation office (after delivering) March, 3 – March, 6 - start co-working SRC delegation and S1 support engineering group, - installation necessary SW, - choice of set of environments for testing, - HW installation, - self-testing and self-demonstration March, 7 - Demonstration for top management of S1 Corporation - Meeting with top management of S1 Corporation March, 8 – March, ? - technology transfer

E-LPS Demonstration What will be delivered to S1 Corporation: - 6 sets of BS with power supply, antennas, and WLAN Adapters, - 2 battery operated beacon transmitters, - 8 battery operated tags, - E-LPS Monitor SW What will be required for demonstration preparation: - testing environments that must have open structure, - sets of floor plans in AutoCAD format with exact sizes, - it is very desirable to send the plans to SRC before, - one notebook PC with Windows XP or Windows 2000 and Microsoft Visual Studio NET, 2003, - spectrum analyzer and oscilloscope, - to prepare places on the wall and on the ceiling for BSs and beacon placement and way of its installation (it may be high enough tripods) Important: - preparing for demonstration in new room may require up to one day Already delivered: Already delivered: - Final Report

E-LPS Technology Transfer What have to understand before: - what is qualification of S1 engineer who will be participate, - is it familiar with similar technologies, - how deep technology transfer must be drill down: - operation and maintenance, - tuning parameters what available for the system user, - possibility to changing SW, - self-development of such type of the systems - is it needed to divide the engineers into groups: HW, SW, etc. Due to very limited time of technology transfer What S1 engineers have to do before: - carefully read Final Report and ask questions, - prepare test bed for the system (see requirements for demonstration) Depends of goals of technology transfer and qualification of S! engineers duration of technology transfer must be varied
