Link to Dataset

  • Dataset Link: This dataset includes spectrum occupancy measurements at CC1 (link to dataset), CC2 (link to dataset), and LW1 (link to dataset) fixed nodes over a period of one week. AERPAW team is working on automating the spectrum occupancy measurements and releasing the data periodically through aerpaw.org in the future.

Equipment and Software Used

USRP B205mini on fixed Aerpaw node, UHD1 Spectrum monitoring software

Description

In this experiment, spectrum measurements are carried out at the AERPAW fixed nodes CC1, CC2, and LW1, for a period of 1 week, for 24 hours every day. The USRP B205mini continuously sweeps the spectrum up to 6 GHz and power measurements at each frequency band are logged. The results are post-processed in Matlab to observe the spectrum occupancy at different bands, and we observe the effect of different days/hours of the week on spectrum occupancy as well as the specific urban/rural locations of the fixed nodes on the spectrum occupancy.

Both spectrum results are post-processed using a moving average filter. CC1 is a lightpole fixed node and CC2 is a rooftop fixed node at NC State Centennial Campus. LW1 is a tower fixed node in Lake Wheeler Field Labs.
