It all depends on what speed your shooting for at the shop Ubiquiti is selling pretty simple point to point radios now. They run about $500 and have the poe injector included with them. The simplest setup would be run cat5/6 cable from your router in the house to the radio, it will connect to the radio at the shop. The radio at the shop then would connect into a switch to hook into a wireless access point. The wireless access point would then give you wifi at the shop. Ill include a link to Ubiquiti for the plug and play radios. https://store.ui.com/collections/unifi-network-wireless/products/ubb-us
