Instruction on the Wi-Fi network at a great distance

Suppose there are two remote object (eg, Ethernet). Since there is no way to combine them directly (because of the large distances),
 our task is to solve this problem by using Wi-Fi.
Possible drawbacks
Naturally, the construction of Wi-Fi network is not without pitfalls. The first thing to determine the choice of equipment. Because of the enormous diversity Rinke Wi-Fi adapters, amplifiers, antennas, the choice is far from obvious. The problem is that the data rate or the presence of possible losses in the channel vary greatly, depending on the load of ether, the terrain, the weather. Often the model behaves differently, depending on the conditions mentioned above. Wi-Fi adapters
