Time- and frequency-variant 2.4 GHz ISM band channel gain. 

The time- and frequency-variant channel gain is measured in the presence of an industrial cyclic moving robot arm obstacle for four coexisting wireless nodes for the whole license-free 2.4-GHz-ISM band with a time- and frequency-resolution of 110 microseconds and 1 MHz, respectively. Results for two links are given.

A pcap file containing 122,989 anonymized Probe Requests sent by mobile devices at the Glimps 2015 music festival in Ghent, Belgium.

A collection of 122,989 Probe Request frames captured by 8 monitoring stations at the Glimps music festival in Ghent, Belgium (10 - 12 December 2015). To minimize overhead, each monitoring station individually stored only the transmitter MAC address and Information Elements per unique MAC. The dataset was used to show that the high entropy in Information Elements can be used to deanonymize devices that use MAC address randomization.

Channel energy levels from Wi-Fi networks as seen from a 802.15.4 radio.

We use a sensor network composed of TelosB motes deployed in the library building to collect RF energy level samples (RSSI) on all 802.15.4 channels in the 2.4 GHz ISM Band. The building has several collocated Wi-Fi networks in normal operation. These networks produce interference for the 802.15.4 radios. Sensor nodes record RSSI values every 20 us, simultaneously on all channels, for 130 ms and then write the result to the respective files. This process is repeated every 8 seconds for around 4h.
