Probably the most common form among wireless antennas is a directional Wi-Fi antenna. They are widely used to form networks that operate on a point-to-point basis. When your computer needs to establish a connection exclusively with a specific access point or with some other computer, a directional Wi-Fi antenna will be the best solution. Whether in a room or office with thick walls, this device provides reliable wireless connectivity. Some gardeners organize a stable Internet connection using directional antennas.
Such devices having a cylindrical shape, the diameter of which is about ninety millimeters, have proven themselves well. The length of such antennas is about one meter. This directional Wi-Fi antenna rotates in the right direction, thereby as if pointing the way to the waves. Its gain is eighteen decibels.
If you use it, your speed of about one megabit per second can be transmitted up to five kilometers away. If the speed indicator is fifty-four megabits per second, then it will be transmitted over a distance of one and a half kilometers. Of course, I doubt that such opportunities will be needed in offices, and the length of the product is quite impressive. Basically, such antennas are used to increase the range of a pair of connected stations to each other. But the whole house opposite you will not be able to provide the Internet.
For a room, a more directional panel-type Wi-Fi antenna is suitable. It is an ordinary flat rectangle that emits radio waves in one direction. The gain in such products is six decibels, and the length is slightly more than ten centimeters.
This option will be more suitable for indoor use. A speed of one megabit per second is transmitted up to sixty meters, and a maximum speed of fifty-four megabits per second is up to twenty-five meters.
As for where the directional Wi-Fi antenna should be installed, this is not so important. It can be both outside and inside. For external use, it is advisable to ensure that it is not affected by atmospheric precipitation. Build some small protective box for her.
Such devices are ideal for connecting two points wirelessly. To make you understand what I'm talking about, I will give an example. Imagine that your friend lives in a neighboring house opposite yours. Its balcony or window is right at your level. In order for you to be able to connect to each other via a wireless connection, you need to use a directional antenna.
As for the signal transmission distance, it will depend on what kind of gain the antenna has. And given the fact that some managed to transmit a signal over a distance of more than ten kilometers, this should not be a problem for neighboring houses.
