Internet bridge from house to shop.
My shop is about 85 ft from my house. I bought a KUWFI bridge setup off Ebay and ran a cable to the end of my house in the attic and mounted the transmitter under the peak of my house. I put the receiver on the shop and ran a cable to a router I picked up at a garage sale. It works great. I control my shop heat, have a switch for my air compressor, and a few other items controlled by my phone. I can use Wifi on my phone or take my laptop to the shop to check out ForAbodiesOnly!
Cell reception was non existent in my metal shop so I bought an amplifier off ebay and mounted the antenna on the end of the shop and cabled to the internal tansmitter. 5 bars at all times inside the shop now.
