Motivation
• Develop advanced technology solution to address the safety issues raised in our community.
• Develop accurate localization technique to cover both indoor and outdoor location details of users
Recap From the last presentation• Background Study
Current commercialized products do not have indoor localization capabilities
Patents do not present cost-efficient or accurate enough solution to indoor localization
• Challenges
Triangulation Issues:
Not enough access points to do triangulation. Inaccuracy due to signal strength and multipath Propagation.

Initial Implementation Methodology
• Transferring data from Android phone to Matlab • Instrument Toolbox to receive the data• Under Investigation• Database and server information sharing• Kalman Filters and error correction
Challenges
• Server overloaded with real-time data• Initial android application algorithm not
providing accurate data due to clock sync problem
Conclusion and Next Step • Good Result#1:• Able to send data from android in real time• Able to receive the data directly in Matlab
• Unsolved Problem #1:• Apply the theoretical algorithm in Matlab to compute
the position
Time Management• Step 1 Sept25/2013 Project Selection Form • Step 2 Oct24/2013 Background Review• Step 3 Nov8/2013 Design Review 1• Step 4 Nov15/2013 Design Review 2• Step 5 Nov20/2013 Implementation Review• Step 6 Dec to Feb CDR 2, 3, 4, 5, 6, 7• Step 7 Apr16/2014 Final Demo
