The guy clearly does not understand what is he doing if he thinks the gain of antenna is 9dBi. The page doesn't show how the coax cable is attached to folded dipole and how it is impendance matched.
The difference here is that you don't have to have cell phone. The device they created works as radar - detects moving objects. These objects don't neccesserily have to carry cellphone.
The UK has discovered that radio waves can go through walls now? You mean I no longer have to go outside to talk on the cellphone? Will wonders never cease.
No they are still working on that
Quote from article: Researchers are working to give the new equipment 'X-ray vision' - the capability to 'see' through walls and look into people's homes.
It works on my orinoco but needs a bit kernel/orinoco driver tweaking. By default this _does not_ work on orinoco cards i.e. mac is not changed. Yes I verified that. Basically hermes_write_ltv(hw,
USER_BAP,
HERMES_RID_CNFOWNMACADDR,
HERMES_BYTES_TO_RECLEN(ETH_ALEN),
dev->dev_addr);
when resetting card does the trick. (i'm using orinoco_cs drivers). If you are lazy to add this code where appropriate, use these patches. They support mac changing plus monitoring mode for orinoco/wavelan cards.

Think of it as the accesspoint with highly directional antennas to all clients.
Client A will not hear traffic that is sent by AP to client B.
Wow pretty big horn must that be.
Assuming waveguide is about 9dBi, the Horn must be 25dBi. High gain dish antennas are of that gain.

At 120GHz? There's no way radiowaves will pass thru walls at freq this high? :)
Well maybe very very thin walls
