how a network works

how a network works:

Wireless networks or WLANs act as a wireless device - to connect a computer.

Wireless or WLAN serves the same purpose as a wired device - to connect to a computer. Since wireless does not require expensive cable, the advantage is that it is usually easier, faster and cheaper to install.

On the contrary, it is a difficult task and therefore expensive to create a network by using wires on walls and ceilings. But even if a network were already in place, wireless networks could not be an economic means to expand or expand. Of course, there is no wireless network because most people will reconnect to the network in time.

Basics:

Wireless systems use radio frequency (RF) technology, which measures the frequency at which the electrons of a radio wave propagate. When the RF current is transmitted to the antenna, an electric field is generated that can propagate across the field.

The backbone of a wireless network is a device called an optical array (AP). The main function of the access point is to transfer the wireless signal to a computer that can detect and "configure." Because wireless networks are connected to wired devices, access points are often used as a connection to wired equipment, such as to connect to the Internet.

To connect to an access point and a wireless network, a computer must have a wireless card to carry it. It is connected to the computer, but if you do not have one, you can connect any computer or laptop to a portable slot, USB port, or, on a laptop, those who prefer a connection connected to PC and card slot.

Wireless speed and range:

When you purchase wireless network hardware, it indicates a number of features (ie data transfer) and is based on the standards of the wireless standard used, with technical improvements. Honestly, these results are always optimistic.

Although the internet speeds of 802.11b, 802.11g and 802.11n are 11, 54 and 270 megabits / s (Mbps), these figures show a positive development as they are not available. In general, you should expect to receive only one-third of the media performance.

It is also important to keep in mind that wireless networking informs and defines distributed networks, which means that other computers you are connected to wireless technology will reduce the amount of data you send and receive. Just as air conditioning can be very diverse, so can the environment. For example, the 802.11b g steering wheel works slightly, reaching 100 meters indoors or 1,312 meters high, but the key is to "reach". You probably will not see anything for these numbers.

As you can expect, the closer you get to where you are going, the stronger the signal and the faster the connection. The quantity and speed achieved by transport and air conditioning depend on the operating environment. This leads to intervention.
