“…However, previous work has shown that, in general, rural and suburban delay spreads are smaller than in urban or dense urban areas [28], [29], [30], [31]. Our results in Table II show a similar trend, since the residential and commercial areas can be considered suburban and have lower average RMS delay spreads than the urban downtown area.…”

New techniques in cross-layer wireless networks are building demand for ubiquitous channel sounding, that is, the capability to measure channel impulse response (CIR) with any standard wireless network and node. Towards that goal, we present a software-defined IEEE 802.11b receiver and CIR measurement system with little additional computational complexity compared to 802.11b reception alone. The system implementation, using the universal software radio peripheral (USRP) and GNU Radio, is described and compared to previous work. We validate the CIR measurement system and present the results of a measurement campaign which measures millions of CIRs between WiFi access points and a mobile receiver in urban and suburban areas.
