This memorial day weekend, I went camping out of a bed and breakfast that had open wifi. When I went out on a hike one afternoon, I decided to see what kinds of wifi signals I could get I could get on my Android phone. I got on top of a pretty tall peak where I could see the bed and breakfast.
I was surprised when I was still detecting the wifi signal from the bead and breakfast (although it was very faint).
When I got back home and saw how far away I really was, I found that I was about a kilometer away.
I could only establish a very sketch connection that would only last a few seconds, barely enough to load a single web page before cutting out. I think it's really phenomenal that consumer grade wifi devices can get range like this. Granted the source and I were in direct line of site to each other and I was in a rural area with minimal interference.
Has anyone else seen anything similar to this?
