Jack and Frank I've read your book; has been a HELL of ALOt of help! Great stuff! However passive repeaters are only mentioned, and my question is this: I have an AP at 1km west from my flat, but no direct view. I have a friend's flat 50m north and higher up who does see the AP. After trying to calculate freespace loss using a passive repeater, for two radio journeys (1km=100dBm, 50m=78dBm), it seems I need a signal that is 178dBm stronger than my reciever threshold? I am assuming that the repeater will not lose any power just to keep things simple, and was thinking of 2 similar 14dB gain yagis that theoretically will not add anything only redirect the signal 90� south from my friends flat to my flat. With this calc., I seem to need a transmitter with more than 93dB power to get a signal on a -85dB card! This is obviously not possible with 802.11b! Is there anyway around this? Should I use different antenas on the repeater? Is repeating at tese low powers only possible with a powered repeater?
Any help would be ideal as I am trying to set up a LAN with a webcam on the AP looking out over Santa Cruz. PS. If the webcam is at the AP, the easiest solution to see it on the WLAN would be plugging it into a LAN port in the AP? Thanks Andy, Tenerife
