6 From science fiction to science Enabling technologies: wireless access and locatization
7 A new realm: BAN What are the bounds to wireless access and localization? March 9, 2011
8 How the technology evolve? Understanding of the channel is essential to determine the bounds
9 Which channel? What band? March 9, 2011
10 What models for RSS? Multipath fading Average received power Shadow fading Distance in logarithmic scale 10
11 11 What models for movements?
12 What models for data rate? T 1 R Inter Symbol Interference (ISI) 12 Lower bandwidth for more reliable data: Wider bandwidth more reliable localization Tolerable ISI: R 0.1 rms
13 What to model for localization? The first path is not detectable by measurement system - Undetected Direct Path (UDP) [Pah98] Measurement bandwidth is not wide enough to distinguish the first few paths from each other [Ala03] Limitations on Bandwidth Undetected Direct Path [Pah98] K.
