I'm especially wondering about wifi aplifiers (2.4GHz and 5GHz).
I have a couple of very basic questions about them. (I hope this is not too much for a single question):
- Are there special signal amplifiers for routers and for client machines or would the same amplifier work on both? (I'm wondering because this one says "don't connect with network card".)
- Does a signal amplifier work in both directions (upload and download) even if only one of the two parities is using such a device? (The one linked above says "bi-directional", has this anything to do with this?)
- If it would actually work for both (sending data and receiving data): how does this work? I get that you can use an amplifier to make your sending signals stronger, but are the amplifiers also be able to better pick up weak signals?
(I am well aware of the strict laws related to transmit power limits etc.)
