Scientists in Australia have developed a new approach to wireless networking that allows a DVD quality movie file to be transferred from one machine to another in less than a second. The system represents the first step direct wireless connectivity of up to 12 gigabits per second and could find applications in urban wireless networks, emergency response situations, and other environments where wired networking is not practical.
The CSIRO ICT Centre has announced that it has achieved over six gigabits per second over a point to point wireless connection with the highest efficiency (2.4bits per second per Hertz) ever achieved for such a system. Multi-gigabit links operate at speeds that leave current wireless networks standing. For example, the entire works of Shakespeare could be transmitted over this six gigabit link in under seven thousandths of a second or a full DVD movie file in just over three quarters of a second. The team can transmit sixteen simultaneous streams of DVD quality video over a 250 metre link with no loss of quality or delays.
This impressive demonstration nevertheless only utilises one quarter of the capacity of the link. Jay Guo, Director of the Wireless Technologies Laboratory at CSIRO said that this breakthrough is just a first stage towards direct connections of up to 12 gigabits per second.
"The system is suitable for situations where a high-speed link is needed but it is too expensive or logistically difficult to lay fibre, such as in congested urban environments, and across valleys and rivers," Guo said. "The system is also ideal for creating networks to meet short-term needs such as emergencies and large events."
The system operates at 85GHz in the millimetre-wave part of the electromagnetic spectrum (above 55 GHz) which offers the potential for these enormous speeds and is not yet congested by other wireless applications.

you could always rent a fog machine for the day, like the ones they use on stage. The fog fluid doesn't cost much and it won't stink your place out
Light a piece of paper on fire or something and test in the garage.
that may be hard, sister moved back in whilst she does her new house up, all her boxes are in the garage, cant even use my gym suff in there :( i'm developing MOOBS!!!!!
/me whipes tears off, anyways.... I'll have at my dads, hopefully i wont burn down the house.
U can get `smoke in a can`, I`ve seen fire-alarm installers test alarms in warehouses with them.
Have absolutely no idea how available it is, or indeed how much it costs.
How about a big arse army issue flare !!!! lmao

Ive thrown the same type of smoke nades the army/SAS use. I think he might actualy want to be able to see the smoke going into the case, with one of them in a grage you wouldn't be able to see your hand infront of your face:p
lmfao, that reminds me of messing about in my dad`s garage as a nipper and finding an old fire extinguisher. For some dumb arse reason I figured the handle won`t squeeze coz it`s stuck... prehaps hitting the handle with a hammer will budge it..
The handle was hence stuck in the open position and I dropped it and got out, slamming the door closed.
The whole garage was white powder coated.
Looked ever so tidy tho ;)

I was watching this thing on TV about house inspectors and they were looking for drafts and they actually had this little tube and when you squeezed it this very light smoke came out and blew one way or the other if there was a draft.
If only i knew the name of it cause it'd work perfectly for what you need it for :(

you sure it wasnt a fine flour or anything, i remembeer those fake cigs kids have, that when you blow it blows out flour and looks like smoke.
Lol ahhh i remember them :rolleyes:
But nope it wasn't like a floury smoke. It was a very floaty smoke that was whitish in color lol

wasnt from a place like columbia was it?
I use a few thin yarn strings tied to a stick..
But here is the smoke in a can

only prob is it dosent last long
When I designed my comps I built a air flow gauge. I got a 2' piece of clear plastic tubing that a golf ball fit loosely into and attached a hose to the bottom. As you blow in the hose the golf ball raises.
That worked well to check different fans and grills/mesh.
My best gauge was my face though, if you blow against ur face its a lot easier to feel the air.
