Laserbeam data transmission from ISP peering point

[John]

www.is.co.za are under severe strain they are not involved in ADSL..ect. Ian at www.is.co.za told me he would allow the transmission of data from their peering points with a LASER BEEM
or parabolic. Mircrowave has fresnel zone issues and ofcourse a parabolic on the roof would alert the regulator. A laser beam (data > 10meg) can't be seen. The transmitter can be plastered into the wall on the peering point or installed behind a window. The range is 5km.

This is a foolproof system to get data out of an ISP..because nobody will know about it!

ODLAN data transmitter systems – which only differ by Signal transmission spectrum (200 kBit/s to 155 Mbit/s) and their maximum distance (400 m to 5000 m) – are built for a safe wireless data transmission between buildings or from a fixed ground station to a mobile crane plant.
The ODLAN series is particularly developed for connection to the Ethernet and is equipped with fiber-optic cable as interface.
ODLAN 95 has a particularly widened divergence, in order that at an uneven crane tracks, communication from the crane to the ground station can be ensured.

Foolproof, yeah & illegal as far as I am aware...

I'd love to implement something like that here in CT - if I wasn't moving I definitely woulda done something with that... but there's always the next house
Hopefully a house where I can rip out every cream-coloured Telkom line and rely on someone who cares about the country.
Thanks for the post John, always good to know about options!

Mad there is way you can subvert the laser beam. Very few
people know about this. Even less know how you can counter this
'subversion'. (And no I am not talking about placing a mirror infront
of it, you can't see it remember...)

I won't discuss it here, but if you ever run into
trouble with you laser beam, then just email me, I will tell you
what to do.
==============
How many people for example knows that if you put on a thermal insulating suite the passive IR sensors of your alarm system won't detect you.? And after this the crook sprays a substance on the the sensors masking them permanently? This can be countered with anti-masking sensors that emmit a short range ultra-sonic beam...
Yeah , this stuff gets complicated...

How many people know that there is a way to subvert the laserbeam
security system around your house? How I will not tell.

.... and Mad thanks for the kind words....

John, you probably have the best intentions, but seriously dude you need to get real. One minute you;re the world's expert on wireless nodes and meshboxes, the next minute you're the resident laser data transmission specialist.
Laser was looked at years ago by telcos, and they all concluded that it wasn't robust or reliable enough for outside use. The reason is because laser is subject to refraction, needs line of sight, will not work in bad weather, is costly to maintain and also requires exact calibrations for installation. Its way easier to slap down cabling.

Since we can't do that without getting caught, ad hoc wireless networks are probably the best way forward, but until they become legalised we're screwed...

You are wrong the problem has been solved:

http://www.usatoday.com/money/covers/2002-04-11-terabeam.htm
http://www.airfiber.com/
The combined technologies of the HFR solution eliminate the limitations each technology has alone. Heavy rain, which severely limits the reach of 60 GHz wireless systems, does not significantly affect FSO transmission. And, fog doesn't inhibit 60 GHz signals. Since fog and rain can't occur at the same time FSO and 60 GHz radio systems perfectly complement each other and enable a powerful last mile solution.
http://www.terabeam.com/home.shtml

On the days that it rains we park
a van with an Omni outside www.is.co.za peering point and just pop
a 5.8ghz 5dbi patch antenna at the www.is.co.za window.
Inside the van you have a Yagi blasting the signal down the street to
our a Linksys WRT54G router.
http://www.sveasoft.com has written an opensource Linux driver for
this wi-fi router and describes step for step how to set it up for
outdoor use. The SVea Linux software solves the Hidden Node problem
as well.
http://www.sveasoft.com/modules.php?name=SveasoftArticles&op=SveaReadArticle&id=1

The WRT54G are imported to South Africa by:

Or another idea. Fit 3 people with rucksacks, mini-itx motherboard,
battery pack and have one stand outside IS peering point and
relay the signal with omni's down the road to connecting node.
Just rotate them in shifts for 24hour connectivity.

You can't have a van outside of www.is.co.za peering point as a permanent solution, only when it rains!
Or build a 18dbi 5.8ghz panel antenna, into IS wall, it will just
be as covert...
=================

Please keep on exposing potential problems... []

This laser beam is just to expensive. A 10meg data beam
will be around R30 000 at the least. So just forget about it.

Just bridge two parabolics from building to building 5.8ghz with
each parabolic behind a window.
A 5.8ghz parabolic data stream is tantamount to a laser beam. It is outrageous to suggest that Icasa is going to start driving around peering points looking for 5.8ghz.

I have link to somebody who built a 10ghz transmitter. I managed 10meg
I just can't find it at the moment.

lewstherin,

The only thing you can do with this one is give up...

I hate to say it but if we wait for things like this to be legal in SA we will be in the stoneage compared to the rest of the world. I for one am seriously looking into this...

Don't get me wrong I am all for good legislation but when it is clearly not in the interest of our society then I get worried and I also feel a lot less guilty when I ignore the antiquated laws... It sometimes feels as if our some of our laws exist purely to make somebody else extremely wealthy!

Cheers

Ok I think I finally have the solution.
Lets just get 100 people together and go to www.wavestream.co.za
We will install everything ourselfs with www.locustworld.com
meshboxes and www.wavestream.co.za or www.sawireless.co.za
will be our 'fronting' company. They will take full legal responsability and we will pay them a monthly negotiated fee.
There are now many commercial WISPS , so we are in a position to
negotiate.

 

[entrepr]

a parabolic on the roof would alert the regulator

I must be missing something. There are many legal ways to get data out of Jinx.

Perhaps it is the age of the thread?

Thanks for the seriously good laugh after a crappy day.
