Let's say I lived in a big house, and in my big house I had a wifi connection that was fairly weak. So weak, that inside of my room I would only receive one bar of signal. How would I design a circuit that would catch the wifi signal, amplify that signal, and rebroadcast it inside of my room? This is a problem I just thought up in my head and I was wondering if something like this is even possible? If it is possible, what specifications are needed to design the circuit?
