I would like to pose the question of weather or not it is feasable to extend a wireless routers signal over an extended antena which could thread through the cealing of a building to alow a signal to be used from room to room. The building in question predates wireless networking and was constructed with a structure that does not allowing a signal to pass through the various walls. I have not attempted anything to produce a signal yet because of time constraints on my schedual. However, i was wondering if there any factors to consider other than the resistivity of the antina material which would be used to transport the signal? If anyone has atempted this in the past or has an idea of how to get around any complications that this set up would create please respond with any ideas that may help.
