Show HN: Concurrent Wifi Users
- jftuga 11y agoThis shows wifi user locations throughout a day with each room having one AP. Devices consists of laptops, tablets and phones using various 802.11 wireless standards. Data was collected throughout the day from a pair of Cisco 2504 WLAN controllers. The controllers were queried about once per minute and the usage was saved to a CSV file. I then wrote an R script to transform each sample into it's own PNG graph. I used ffmpeg to merge all of the PNG files into a 1080p MP4 video.
