What is wai fay

First, the data networks were wired and low-speed, later high-speed wired networks appeared. But the idea of creating something new excited many minds, and now there is a wireless network. Let's deal with this new concept.

So, what is wi-fi? Wi-Fi involves the transmission of information on wireless technology. This system allows you to connect to the network on a wireless basis, using radio signals. Many people know that radio waves are the longest waves in the spectrum, their length can range from the size of a football field to the size of a volleyball field. Through radio waves, signals are transmitted to radio receivers, television sets, mobile terminals and so on.

Understanding what a Wii fay is, it is worth mentioning the concept of an access node. It is understood to be understood as the designed node of the local wireless network, which is assigned the tasks of the central transmitter and receiver of this network. The access node usually consists of equipment that includes an antenna, a radio transmitter, and an integrated network adapter. Now it is possible to mention the term Hotspot, by which it is customary to understand the territory equipped with access nodes, allowing the client to connect to the network. Such territory can be accessible in various spheres of business, at home; Wi-Fi is widely available in airports, hotels, cafes and other places where it is provided free of charge or for a very modest fee.

Understanding what wai fi is, it is worthwhile to say about other concepts. Hotspot is the zone of action of one or a number of interconnected nodes for access. It can cover different spaces. This can be a small room where the walls are made radio-tight, or a zone of several square kilometers, where several access points are located. In this way, the so-called mixed, or cellular, connection can be organized. Thanks to this technology, a peer-to-peer connection is provided that allows devices to directly communicate with each other. This method is often used for network games, as well as when working with various electronic applications.

The organization of the wireless network at the initial stage was fraught with many problems related to the interaction of various devices. After this, the association called Wi-Fi Alliance began work on this problem to meet the needs of users through the improvement of technology. If the device has a stamp "Wi-Fi Certified", then this is a guarantee for buyers that it will interact with similar devices. Such products are able to use an arbitrary access node that allows communication with other devices that have the appropriate certificate.

Now we can say about the SSID device and its purpose. Their distribution is directly related to the service for setting the identifier. Thanks to this code, it is possible to connect all the packets in a wireless network. The code consists of numbers and letters. Devices trying to connect to each other over wireless channels must use the same code. The process of such a connection is usually called an association.

So, if you have not yet understood what wi-fi is, you can tell about important components of Wi-Fi devices. There are two components that are considered to be the main ones. These are computer devices, including radio technologies, and low-power devices-access nodes connected to a local network or the Internet on a wireless basis. They are connected among themselves by means of a free radio range, which is specially created for users.
