Long distance WIFI link to Cyprus ?

jp-3482

Hi everyone,

I remember reading that someone from Tripoli (in the mountains) managed to connect to Larnaca, Cyprus with two big dishes on either side.

We're talking a distance of approx 150 miles, what do you guys think?

Impressive.

There's a guy on the Mikrotik board that was offering to setup a 2 Mbps link to Cyprus for 15 000. I'm not crazy to pay that much, can you imagine paying and getting disconnected shortly after.

So far it looks like a 3M dish is required on each side, at >1500 M altitude (Bcharre?) to be able to target Cyprus.

I am no telecommunication expert, but here what I think. There are two ways to connect to Cyprus by the mean of wireless communications:

-Microwave links: Usually it uses extremely high frequencies (20 GHZ and above), they are affected hugely by weather conditions and solar winds, they have a large bandwidth, they need to have a line of sight, but they don't need a huge Fresnel Zone, so they don't need to be placed at very high altitude if the line of sight is available.

-Wi-Fi Links: It uses the 2.4 GHz band or the 5 GHZ band, weather conditions and solar storms have a very little effect, its bandwidth is far less than Microwave links, need to have a line of sight, and a large Fresnel Zone.

Now to connect to Cyprus you will need high altitude in both methods because the earth is curved and line of sight is not available with Cyprus below 1500 meters.

Good info, I have heard that since we're over water we need over 5 GHz on the Wi-Fi side.

so, what's the going rate for fiber per mile/km?

Edit nevermind: $15 per meter * ~400km = prohibitaly expensive unless an ISP were to be set up.

It's probably illegal but what would be the consequences if you got caught ?

LOL, it is impossible for individuals or even for small companies to set a submarine communication cable for such long distances... it is very expensive (millions of dollars the price of the cables alone), and installation equipment are not cheap (you will need a specialized expensive ship to install them), and off-course you should have specialized engineers and do geological studies to install the cables safely...

Nothing will happen... they will just take the dish and the equipments... and if you live in an area out of the government reach they will do nothing (I am not pointing to anybody, because Lebanon from its south to its north is full of such areas).

I think that only wireless links to Israel are strictly prohibited, because stupid government thinks that spies and intelligent agents will communicate with Israel through that secret wireless link (LOL, as if they never heard of encryption, where any guy can communicate with Israel securely through a VPN using any DSL Internet connection).

Someone is telling me there's no way that I can get a signal from Bcharre that I would have to be between akkar and dannieh what do you guys think ? That kills the idea. Unless I setup a second relay but it's getting complicated!
