I work in IT and need access to WIFI in case I get paged. In the summer I go quite often to a campground that has a WIFI hotspot at the main office. If I get paged in the middle of the night, I have to walk up to the office with my laptop since the wifi only reaches about halfway across the campground.
It would be neat to build a portable WIFI repeater using a Raspberry PI, solar panels and batteries encased in a waterproof box that could be placed halfway between where we camp and the camp office.
