Nope. You can amp your signal and use a directional antenna and the other
end can be using a low power antenna. It is a common belief that both
ends need to use the same antennas or be amplified. This is n

Well since its a transmitting/receiving relationship, you need to find the
carrier frequency of the WLAN and perhaps run around with a Field Strength
Meter tuned to this frequency. For this to work properly of course, you'll
need to be able to turn off all the other transceivers. Or else, you will
