UWB Indoor Channel Experimental Data

The MeasureMINT (MINT stands for multipath-assisted indoor navigation and tracking) database contains position-resolved ultra-wideband channel measurements for several different indoor environments. These measurement campaigns were conducted to allow for an evaluation of the MINT indoor localization scheme, but may be of use for any research topic dealing with indoor radio propagation. Measurements were obtained either with a vector network analyzer, hence they are available as frequency domain channel transfer functions, or with an M-sequence radar device, hence time-domain signals are available directly.

 

Measurement Documentation

A documentation of all the measurement campaigns and scenarios is available here.
