Bicycle Measurement Platform “Cart-o-Science” Measurement Rig Anritsu 2.4-2.5 GHz Antenna (5 dBi) GPS Antenna 2 RP-TNC M to 5' LMR-200 RP-TNC M Coaxial Cable adapter Total cable loss ~ 1 dB N M to RP-TNC M adapter Anritsu MS2721B Spectrum Analyzer Cat 5e Crossover Cable GPS Antenna 1 Intel 6250 WiMAX MiniPCI-Express Garmin GPS60 Control Computer (Samsung Netbook) 100m Lagged Equilateral Triangle Grid Sample

Preliminary Mapping Results Kriging-Interpolated Coverage Map using Effective SNR @ 6Mbps Including measurements and “pop through” 3D building models

Multiple Metrics Mapped: - ESNR - CINR - EVM - RCE - Spectral Flatness Error Vector Magnitude Map (for instance) Interpolation technique (Universal Kriging) Residual Map Uncertainty Produces plot of map's (Kriging Variance) Residual uncertainty... For Effective SNR Map
