Long range Wi-Fi for remote location

I think he was just referring to not having to run 240V power cabling to power the remote end, use PoE instead, which should be installed by someone who at least has the ability/equipment to test it correctly. Here in the UK an external 240V cable run like that would need to be signed off/certified by a qualified electrician.

Yes Steve is correct, I meant you don't have to be a licensed electrician because you don't need to run 110/240v power.
In Australia if you terminate CAT5 then you have to be a licensed cable installer, most electricians are. But for example, at home, I just ran a CAT5 cable through my roof but I didn't terminate it, it just runs straight to the nanostation so this is no different to patching in a computer to a router.
So to be clear, you don't need any radio licenses to run this ubiquity radio gear, at least in Australia anyway, because it is all on 2.4 or 5GHz spectrum and it is not against the law. I would however suggest you try and use the 5GHz range because you will get less interference from 2.4GHz devices.
Also it won't interfere with existing radio equipment most probably anyway as all the older more serious wireless gear will operatre in a licensed spectrum which is different to 2.4 or 5GHz. In other words you could safely mount it on existing radio masts like you mentioned.
Thanks,

Really? In your own home? On your own network?
Surprisingly regulated. Interesting how things vary between countries.Steve

Wow!! I guess then that I would be doing 25 to life with the installations I've done so far…

Yeah it sucks. I did the cat 5 cabling in my house though. But because I used cheap ebay cat5 I only get 100mbps not 1000mbps which really sucks.
-
Ouch! I must have just been lucky because I've never spend much on cat5 cable and never had any problems getting 1000Mbps. Of course that's once it was terminated correctly, very easy to get one wire not connected and then the connection will fall back to 100Mbps.
I must remember that if I'm ever back in Australia. Last time I was there I..er.. didn't know that. ;)Steve

There are limits to the max. EIRP in australia:

pages 12, 13 and 14I find the regulatory documents for 2.4 GHz quite confusing….
Apparently the rules in australia are closed tied to the FCC rules.

I think it's safe to use the values provided by this page. -

I think it's safe to use the values provided by this page.You have to choose which country you are in and the radio will then not allow you to exceed the maximum transmit power for your country. You can easily just change countries, I think Russia is the least regulated. But whatever the limit is in Australia it's plenty powerful enough.

7 years ago I did this with normal AP from d-link at fixed speed 54mbit but using 100mw But 21 DBI antennas (not legal) and a clear view. 4km and I hade around 30-40mbit up and down in bridge mode.
Now I hade 1/1Gbit fiber last 6 years :)

That's a good result. I struggled to get much of anything with domestic hardware but external antennas over a much shorter distance (~300m). That was maybe 12years ago now. I'm sure I could do better now but with near universal internet access at reasonable cost it's no longer worth bothering. ::)

The country itself is not enough.
There are several layers of "protection" to prevent the user from doing illegal stuff.
The most basic is the hardware itself.
The second layer comes from eeprom/driver. Most vendors default to US. There was just a nice rant by luis r rodriguez on the linux wireless mailing list today: http://permalink.gmane.org/gmane.linux.kernel.wireless.general/124643
On top comes the user provided country code which can only be more restrictive than the previous two layers.Unless you want to hack your own driver, you're pretty much limited to whatever the vendor of the card you're using thought they have to comply to.
This is usually not what you're allowed where you are but much less. -

On longer distances than a few hundred meters you need some way to adjust the timing of the link.
Atheros based cards allow the user to set set this value (in increments of 450m).
On pfSense this is the "Distance setting" field.
That's actually the reason why "normal" Accesspoints/clients aren't able to communicate over longer distances.
Not because of the hardware, but just because you can't configure it correctly.Here in switzerland there is a amateur radio group operating the "ham-net" http://www.swiss-artg.ch/index.php?id=37
Quite fun what they are doing. They are using ALIXes with a moddified openWRT.
Some day i'll have to gain access to their net :D -
Looks like fun. :)
Thanks for that I didn't realise that about the link timing, makes sense now I think about it.Steve

-
Well it allows you to set higher power on the surface.
The lower layers still make sure no illegal levels are transmitted.
Unless you connect a power-meter and measure what's getting out you only get shown a number which might or might not be correct.
