Wireless Tech. Research Article
« on: June 25, 2012, 09:57:28 am »
I came across this article today.

And holy cow! That wireless speed is absurdly fast.

" In Thide’s case, his team transmitted an OAM radio signal over 442 meters (1450ft)." Wireless, it transmits 2.5 terabits per second (equivalent to 320 gigabytes per second, or around seven full Blu-ray movies per second).

"For the networking nerds, Willner’s OAM link has a spectral efficiency of 95.7 bits per hertz; LTE maxes out at 16.32 bits/Hz; 802.11n is 2.4 bits/Hz. Digital TV (DVB-T) is just 0.55 bits/Hz."

My grade on any new product that uses this technology is "Shut-up and take my money!".

And I thought Air Fiber was fast.

It was just a test. The range is small, so if they spread it out a bit, it would get slower, but even at two miles, I'm sure it would be amazing for a backbone.

Yea, it would make an amazing backbone. I still, however, can't see how you could possibly use that much throughput.

only useful to use as a point to point transmission for companies that want to share data between 2 buildings without using companies between, or to have it intranet.  I installed a 10GB relay between 3 buildings about 5 years ago.

We're getting them for SandyNet. We have a few remote towers that are located about three to five miles apart and need to talk to each other. Some cannot get fiber, so We are using a 50 mb connection right now. AirFiber will really speed things up. We hope. It will make a nice failover for a high traffic connection.

Sounds like the perfect system for it.  If you have any valleys or hills, you may need to set up relays at those locations to get to other towers.  Not sure how many towers you have.  In McMinnville I helped installed a bunch of Yagi antannas for sewege pump data relays, and there were a lot.  They had it plotted out pretty well with hills and valleys covered.  There towers wernt very tall so they werent an eyesore having to be in the middle of residential areas most of the time.

What kind of system did you use? Like a 900mhz system or some licensed low frequency system?

I was an apprentice at the time, and all I did was help put the Yagi's in.  I cant remember what sort of receiver and transmitters they used.  Sorry.

The kind you cant climb without training and OSHA, and some of the smaller ones.. basically a pole on the side of a building  (c:

Sweet. I would like to climb our towers, but my job won't pay for the training. Plus I don't think they would let me even after that.

I never actually climbed the big towers.. I was all set to do so.. but the guy that always sets them up did because it was a shared tower, and they didnt want me blamed if anything else got bumped.  There was one other tower that they were gonna have me climb, but we got called down to work in another city for a week, and I missed out.  But the small towers.. more like 1 story shacks with a 10 foot flag pole.. I did get up those.
