How to get internet on the island?
There is an island, 50 km from the mainland. There is a task to carry out the Internet on it. There is nothing on the island. How can I do that?

Smoke specialized articles habrahabr.ru/post/206100 and forums like www.gsmforum.ru before karmic enlightenment.
Do you lie right away and get advice on equipment for free.
UPD "hotel under construction"
Well, call the nearest mobile providers, ask them.
As an option: download the entire Internet to flash drives or DVDs, transport them by boat to the island :))
(a joke to cheer up during the holidays, no offense to the questioner)

How can I do that?
To do this is quite realistic, with a strong desire and direct hands. How to make an Internet through 3 G the link was given to you above. I’ll add on my own that I would at least make an irradiator in the form of a conventional waveguide, where I would place the modem itself in place of the probe. Here is the article on how to determine the frequency of the network, deepole.ru/3g-i-4g-texnologii/opredelyaem-chastotu... Then, using the frequency of the network, we calculate the diameter of the waveguide. Google will answer more detailed questions.
Regarding Wi-Fi, when I was building a bridge for myself, I was warmed by the thought that the world record for communication range on standard equipment was 310 km. The connection was between Sardinia and Italy, the diameter of the parabolas was 2 meters. I finally got it all right. The biggest problem was that there was no direct line of sight, the route ran through a small forest. After manufacturing about a dozen helixes, double and quadruple antenna arrays, a parabola with linear and helix-like feeds, I stopped at a parabola of 0.95 m, a feed of 4 helix turns on the 6th Wi-Fi channel. Ping 8-9 ms, speed 8 Mbps (as much as the provider basically gives for my tariff). Asus RT 10-N routers (all other options, not N, are made on a different hardware) are very good impressions. Bought 4-5 years ago. At first I broke the connection, after changing the firmware (standard, from the Asus website) it began to work perfectly. Does not hang, does not heat up, sees all devices, stable strong signal. For the last 2 years it has been hanging on an antenna on the roof in a foam box without heating. Even in 30 degree frosts, he showed himself from the best side. Asus RT-12 (I don’t remember the letter) spontaneously went into nirvana, a couple of weeks after the purchase. Flush flew. Hands raised did not reach. Tr link 741D. Dual feeling. First I cursed him. But I learned a lot. Excellent sensitivity, sees a bunch of networks, but when trying to establish a bridge, the base point does not hear it. The whole difficulty is that there are two antennas. External for reception, internal for transmission. When you try to place the transmitting and receiving irradiators side by side, it simply stalls. With diversity, the parabola goes blind - either only the speed for reception, or only for transmission. In the end, he won - he made an irradiator in the form of a two-way helix. Everything works fine, but the sediment remains. In addition, when the temperature drops below -15, the flash of the link is reset to zero. Of course, there is a plus - waking up, and seeing that there is no Internet, you immediately know that it was below 15 at night, but the minus is that you need to drive the settings into the router again. If I were making a bridge now, I would take Netis WF2710 (reviews are quite good, at a low price), first of all, to switch to 5 GHz. At a higher frequency, the Ku of the parabola will be higher, which will create a narrower beam, and, accordingly, greater range and noise immunity.
