What is the legality of this? I have a vague suspicion that operating a device like this would violate some FCC regulations.
So this makes the router sends a stronger signal, farther. But how does this help if my laptop still has the same wifi adapter and can't send a strong signal back?
I am wondering if antenna calculations are applicable for all types of routers. If not, how can I adapt it to my own setup?
As an electronics student, are there any resources I could use to learn the basics of RF (antennas, etc)?
if my router has 3 antennas, is there any point to installing it only on one of them? my intuition that's based on exactly no RF experience whatsoever tells me that it'll do more harm than good. (case is weak 5GHz signal in the corner of a house.)
Basic antenna question: I thought with Yagis the elements where connected together, is that not the case? As they seem to be held just by plastic.
Could something like this have any impact on a bluetooth antenna?
interestingly, the antenna optimizer (AO) software uses genetic algorithm to find the right the antenna topology, therefore, this antenna is not designed, it's evolved. more details can be found here: https://en.wikipedia.org/wiki/Evolved_antenna
I wonder what this will do for my 20DBi external wifi adapter.. I can already connect to networks over 600 meters away from my 13th floor apartment..
When he says the antenna in the picture is aimed to the right, does he might OUR right, or the router's right?
This makes the antenna more directional. It increases the range in one direction while decreasing it in every other direction, so I'm not sure how well this would work for most people without relocating the router/AP.
That being said, it's a clever bit of engineering.
