Aussies Put Old Pay-TV Dishes To Use -- As A LAN 159

Posted by timothy from the that's-not-a-wireless-card dept.
Insane Hardware writes: "If you thought the olympic show the Aussie's put on was pretty tops, then this will blow your socks off. Insane Hardware sends in word about a group of people in the country's capital, Canberra (just south of Sydney), who are setting up a wireless air network for game play amoungst many other things (pr0n trading???). So how are these guys doing it and doing it cheaply? Well they are using satellite dishes from an old defunct Pay-TV system Australia had some years back called Galaxy, and are using some standard old full-length WaveLAN ISA cards which operate in the 2.4GHz range to hook up to these ol dishes. " (More below.)

Mr. Hardware continues: "Although not the best speeds, approximately 2Mbps with a 2.2ms round trip latency isn't too shabby when you consider the cost and implementation of this. Hell, you can even learn how to make a reciever dish at this site! So how is it powered? Linux of course! Check out www.air.net.au for more info."

Check out the mailing list archives to see how much progress they've made, too -- perhaps some friendly (and entrepreneurial) Slashdot reader can hook a few Canberrans up with wireless cards for cheaper than they can get them down there?

  • Actually, it looks like they are just using the antennas from the defunct TV service, not the satelites.

    In fact, if you read their site, they are using home-made and other types of antennas as well.

  • I live in Sydney, and on the way back from a recent skiing trip we passed through Canberra. It takes all of 5 mins to drive from one end to the other. Canberra is like a country town, and since the project is specified at "North Canberra" I'm wondering why they didn't use normal cables ;) I can see why /. called it a "LAN" rather than "WAN" though...

  • PS for those who haven't visited us here, Canberra is not that small. And while this project is based in North Canberra, there are people attempting to achieve the same thing in South Canberra.

  • The Galaxy "satellite" dishes didn't point at a satellite either. They pointed at a local transmission tower

    I think you may be confusing the two Galaxy dishes. The genuine satellite service used a solid, offset parabolic dish (so that the feedhorn doesn't obstruct the dish), which was pointed at one of the Aussat satellites (IIRC.) The microwave service used a wire mesh "dish" pointed at a base station. The article refers to "Galaxy TV antennas" which sounds more like the microwave antenna.

    Nice if someone could set up a group/site/thing to coordinate things a bit more, save running into IP conflicts (quite a few seem to be going for IPV6) if they get linked together (even if only tunneled through the internet) and to get some linking going of cos :).

  • Don't let yourself get caught :)

    And with satellite dishes (which transmit directionally), this isn't even too hard to accomplish.
    Unless someone is that stupid to point his antenna directly at some feds, they won't receive the signal, and everything is fine.

    I guess something like that could even be used as some semisecure, because listening in ("wire"-tapping) is kinda impossible if you're not exactly between the sending and the receiving antenna.

    There's an EETimes article about it here [eetimes.com]. To sum up:

    It allows frequency-hopping signals in the 2.4-GHz band to operate at 1, 3 or 5 MHz, with at least 15 non-overlapping channels spread out over a total span of 75 MHz. The average time of occupancy on any frequency shall not be greater than 0.4 seconds, within a 30-second period. The maximum output power is 125 mW at 5 MHz, vs. the 200 mW the HomeRF group had requested.

    This mostly concerns the battle between HomeRF and 802.11, but does give some good info.

  • I looked at the IP registry [air.net.au] and I noticed that while they are using one of the officially unassigned networks (192.168.x.x), they are assigning it to their members (currently 25 entries in this list) in class C chunks. Obviously they aren't planning on more than 250 or so members. They probably should have used the 10.x.x.x range, but maybe this type of project doesn't scale well past 250 or so sites per wireless network.

    But isn't this kind of thing what gave Fidonet such growing pains? The original Fidonet address spec was two 16 bit integers, but then they had to add zones in front, and they wanted non-dialable client nodes, so points were tacked to the end. Some software never properly supported zones, much less points. (And some TCP/IP software still doesn't support variable length bit masks either.) At least with a full class C per site, they don't have to worry about the "point problem".

  • dont give all those canberries all the credit, cause it isnt just them setting it up.

But what I can tell you is, this is soooooooo far from news it's not funny, this project has been underway for at least a year or two.

  • I'm speaking as someone in Canberra involved in this. It started as a fun hack hobby of people in the Canberra Linux Users Group [clug.org.au] but the mailing list has people from other states involved as well. Obviously there's no interstate connection since the cards don't transmit with enough power to stretch the 400+ Km to our friends in Sydney or 800+ km to our friends in Melbourne, and further.

    Anyway, there's not even 250 people in the CLUG, let alone doing the WaveLAN thing, so this limit isn't as silly as it sounds. We're not worried about scalability since there's currently more than enough and if the limit is hit, then shock horror we can vi a file and use the 10.0.0.0 network instead. That's enough IP's for every man, woman, child, dog and refrigerator in the territory with room to spare (heck, 256^3 is almost enough for the population of the country).

    The galaxy antennas have worked mostly well though some people have been having more luck with custom helicals (which is also good since the galaxy ones are rare, anyway it's more fun to build your own)

    One big problem we have at the moment is between the north and south side is a fair bit of non-residential area (read: parks, public land, parliament house, etc) a wideish lake, and a mountain - which is making a north-south link impossible due to the short range of the cards. The guys north-side (the main instigators) have been having more luck as the terrain south-side messes with LOS more.

    Anyway its a lot of fun and I encourage other people who like hacking and get bored with ethernet networks to get involved in something similar in your area. We've already got a splinter group iirc which are using a different card which has a longer range and more bandwidth, and works with modern hardware (the main problem with the wavelan cards imho - full-length 8-bit ISA)

  • Galaxy wasn't a satellite system. It was a surface pay TV system based on microwave transmissions from Telstra tower on black mountain.

    All that the air.net.au people are using are the now disused microwave antennas - they can often be collected free from people who used to have Galaxy. That makes a very cheap way of getting an ~18dBi antenna.
  • Actually the Galaxy antennas in question do include a downconverter/preamplifier which needs to be ripped out before they can be used for transmission.
  • Not really. In order to get the distances, you need to use fairly highly directional antennas. So the restaurant would have to be very well located, and then you'd have to get your dish in to line of sight of another antenna and carefully line it up.

    Since there's a whole bunch of questions on this, and I've got some experience in this arena, I'll impart some of my knowledge.

    No, it's not illegal. The 2.4Ghz band is a public band, so it's not tightly regulated by the FCC. It's a real pain in the ass when you've got a whole bunch of people running in the frequency range in the same area though,... (Guess how I know this?)

    Provided you could get a signal, you'd be able to connect to the network from anywhere. All you need is a wireless ethernet card, and the information on how to connect to the network. (I currently have two different wireless PCMCIA cards, and should be getting a third soon). An actual "dish" is not necessary.

    "Rain Fade" isn't really an issue, unless you're talking HEAVY rain. Rain Fade is a lot more of a problem when you're actually going through the cloud cover (a-la Satellite). The wireless stuff they're doing doesn't work that way.

    That about covers it. BTW, the company that I work for is getting into this technology REALLY heavy in the US. Especially since Cisco bought Aironet, which has a wirless system that communicates at 11Mbps. That's pretty damn fast for radio, people.
  • Actually (IIRC) The 2.4GHz spectrum slice is globally unregulated -- anyone can use it for whatever they want to use it for. Of course this means you can't complain to the FCC (or it's equivilent) if somebody else is causing interference on that frequency. There are a bunch of unregulated (or semi-regulated) frequencies that can be used for consumer products. The frequencies used by cordless (handset) phones are one example; WaveLAN is another. Some of these frequencies are totally fair game; others have a cap on the amount any one station can broadcast (Like CB radio, which is limited to 3 watts, IIRC).

  • It most certainly is point to point. There's no way you'd get the distances covered here with omnidirectional within the legal power limits. The Galaxy antennas aren't "satellite dishes" as such (Galaxy was a surface system), just directional microwave antennas.
  • Seeing as nobody seems to have mentioned it, there's a similar initiative being started by consume.net [consume.net], aiming to do much the same thing around London in the UK. The first masts are going up at the moment, and apparently you can get quite a good range from the `Sarah Lee antenna', i.e. made out of a cake tin and coathangers :-) Maybe somebody who's actually used one can fill me in here, but the mention of it on the mailing list made me laugh.

    An antenna dosn't really do anything by itself. It all depends what you hook up to it. If you connect a receiver to an antenna, all you can do is recieve stuff. If you hook a tranciever up to it, you can transmit & receive.

    There's no real technical difference between the antenna a radio station uses to broadcast it's signal and the antenna on your car that you use to pick up that signal. The difference between a dish antenna and a linear antenna is that the dish is fairly directional whereas the linear antenna is omnidirectional.

  • This type of system would require an existing Satelite system, such as "Galaxy." Other cities could put a satelite up simply for this purpose, but that would take away the economics of it all.

    Would be much cheaper to run digital lines (phone/cable), and then you wouldn't have to have a sat-dish.

    But it's still cool, just doesn't make sense in somewhere like NYC.

  • I don't know about Australia, but here in the US there are strict limits on what you can do with te 2.4GHz band, including rather low caps on the total transmitting power which limits the range of any sort of home network.
    Does anyone with experiance in the aussie equivelent of the FCC have any insight into this?
    Oh, and the link in the article should point to www.air.net.au [air.net.au].
  • If you can make a wireless LAN out of old satellite dishes, then you can surely transmit satellite TV from them also, can't you?

    You can beam it into another user's satellite receiver, if he happens to be pointing at you (unlikely) or you're right off the edge of his dish (where most parabolic reflector antennas have a minor lobe.)

    You'd have a tough time uplinking to the satellite. I understand the receivers are at a very different frequency from what the little piepans handle.

    Did everyone here fail 3rd grade reading comprehension?

    The network described in the article uses WaveLAN cards connected to old dish antennas. You could do the same thing with just about any other parabolic antenna you might have access to (DirecTV, anyone?). At no time does the signal bounce off a satellite -- this is all line-of-sight between two or more ground-based nodes.

    Please stop talking about Iridium or anything else in orbit. You are only making a fool of yourself by doing so.

  • I would suggest a Amateur radio license

    And I would recomend that the hams leave this one alone. You see, if it takes a ham license to run the transmitter, then non-hams can't legally join the fun.

    So, if someone wants to play with this, go read Part 15 of the FCC regulations ("License-free operation and frequencies") and do it there. Legally unlicensed and available to everyone who wants to play.
  • Canberra has also been rolling out 'high capacity optic fibres to within 300 metres of individual homes. The last segment of the connection to the home consists of copper wires, similar to those used in office local area networks. The total bandwidth to every home is a massive 51mbps downstream and 1.6mbps upstream.' I think this is supposed to be a world first. I'm sure this must have already been covered. http://www.csu.edu.au/special/raiss99/papers/cvivi an/
  • Courtesy of the rock-solid and easy-to-setup Apple AirPort.. I have an Orinoco (nee WaveLAN) board in my W2k laptop (ProntoEdit and the TrueSync on my fone only work with Win32 :() and my signal is outstanding..

    At work we demo'd a point2point wireless installation between 2 buildings using 14dB Yagi directional antennae. Solid connection even without direct line of sight (a couple of buildings in the way).. Very impressed..

    Now I just have to get a nice amplified omnidirecitonal antenna for my apt (and hack into the airport to solder the antenna connection ;) so I can compute out on the shared patio..

    Not to be hypocritical, but did the poster just mention the word "Linux" to get the article accepted more easily? I would have thought the hardware news would've carried on its own.

    To my understanding, the limits are only on the outer edges of the band.

    2.4GHz is an ISM band(Industry, Science, Medical), so it gets used by microwaves, X-Ray machines, etc. It's not a licensed band, and is mostly kept open for noise generated by these devices.

  • Academical and Research Network in Lithuania (LITNET) is widely using wavelan technology. For example radio network covers entire Vilnius city (it's our capital with ~700'000 population).

    Check out the map of this network (I'm very lucky to live on one of those small red dots :)). We've recently upgraded most of our wavelans in Vilnius from 2mbit/s to 10mbit/s. It's a pitty this network has only 2mbit connection to the world. [www.lema.lt]

  • This type of system would require an existing Satelite system, such as "Galaxy."

    More precisely, this type of system would require a defunct Satelite system, such as "Galaxy". Or a hardware hacker willing to show you how to make a 2.4GHz antenna.

    Here in New Mexico, a company called LoboNet [lobo.net] uses 2.4GHz LAN/WAN radios from BreezeCOM [breezecom.com] with outdoor antennas to businesses in the more rural areas. (Near Albuquerque and Santa Fe, but too far for DSL or ISDN)

    They have around a dozen customers, and there's no problem with the FCC, since the 2.4GHz spectrum is an non-license spectrum. As far as power levels go, I don't know. But it works quite nicely.

    (Although for some reason LoboNet doesn't have any mention of it on their site... strange. But I know it's there! Maybe there's some mention at the Integrity Networking Solutions [integrityns.com] site, since many of the wireless networking customers go through them.)
  • 2.4GHz is the assigned band for wireless networking in the UK and assumes a mean range per device of about 300 metres. By extension it's probably the same in Australia.
  • Or a software hacker willing to show you how to make a working satellite system defunct!
