Something that I’ve been wondering about, the transmitter on the Pic de Sauvegarde. Lots of people here are saying it’s WiFi... so is it just an actual WiFi access point or is it a small mobile phone repeater? If it’s WiFi you’re going to have to be fairly close and have nearly line of sight to get signal. So anything sent would be 100% sent at the summit.
This is all I've been able to find about the actual signal.
"An hour after the meeting [the olypian witness], just before 4 p.m., Dingley reached the peak of 8,983 feet where she sent a selfie to her partner Dan Colegate.
The photo shows her at the top, with a solar panel and a telecommunications mast on the top reflected in her sunglasses."
