What Are Wi-Fi Networks?

With technological advancement, it is increasingly common to come across wireless Internet technology in a variety of locations, such as bars, restaurants and malls.Understanding how computers connect to the Wi-Fi system is simpler than it sounds.

What Are Wi-Fi Networks?

How it works

In a nutshell, wireless Internet is actually a translation of the common broadband that we have at home, made through a special router, which captures the entire bandwidth of your modem and converts the data to a certain frequency, which Can be distributed among several machines.

All they need to get to pick up the band is to have a wireless network card, or even the new USB network connectors, similar to a pendrive.With few features, it is possible to eliminate network cables from your home by installing the above devices with the help of a technician.

Some details

It is important to note that, like any frequency-driven process, it is important to be aware of the distance from the modem to the computers connected to it, as well as possible interference caused by electronic devices, which can make connection difficult or slow down.To circumvent the problem, there are other equipment that act as additional points for the network, increasing its range.

Another fundamental detail is the frequency pattern used by you, which will need to be the same as the receivers.The most commonly used is IEEE 802.11g, although others are available.Almost all receiving or transmitting devices are compliant with the quoted standard, but must be configured correctly to recognize it without problems.

Watch out!

As previously mentioned, anyone close to a wireless network point can connect to it, which can cause problems, especially in terms of user safety.For this, it is essential to stipulate a well-designed password to limit access to your network, if you are the signal emitter.

When connecting to a hotspot, you should keep in mind that the network is shared by any nearby users, which in some cases may be dangerous.For these reasons, in addition to a good antivirus, it is imperative to have a great firewall to protect your computer from any invaders.

A new trend?

It even looks like wireless technology is here to stay.Today, several peripherals do not need a wired connection to work, such as mice and keyboards, which for many makes their use much more practical.Packed by the mobility of cell phones and laptops, the wireless system is much more practical and dynamic than the common networks in many situations.

With the Internet, the process is progressing year after year, until we become totally unplugged and free of the tangles of cables and wires that, in many cases, make us so frustrated.However, problems with frequencies and connection may delay the change, as for now, there is nothing faster and more functional than ordinary networks.
