Nowadays, everyone wants to be connected to the internet. Especially the millennials cannot imagine themselves without being connected to their favorite social media accounts. They keep updating their profiles with their photographs and news about their day. In fact, some people tend to exaggerate since even when they go out with their friends, they ask for the Wi-Fi password of the place they are in.
But, how many people do actually know and understand what Wi-Fi is? The answer is simple. Most people do not even know what Wi-Fi means. That is really ironic since you can use the internet (and thus the Wi-Fi) in order to find information on almost anything!
Let’s start with the benefits of Wi-Fi:
- Easy Access
As the title suggests, connecting to a Wi-Fi network is really easy and it does not require any technical knowledge. Once the initial setup is in place, all you need to do is find your desired network and connect. Even when you are travelling or when you are in a café, it is really easy to connect to their Wi-Fi network. Just ask for their password.
- It does not cost much
The great thing with the Wi-Fi is that the initial setup does not cost much. In fact, most service providers will give you for free the router that you will need for your setup. Then the fee that you pay every month is relatively small considering that you can connect as many devices as you want.
After the introduction of internet, it is not necessary to be in office in order to work. You can be wherever in the world you like. Especially with the use of Wi-Fi it is possible to work in your favorite environment. Of course this increases your productivity since you can work from your convenient location.
- You can connect many devices simultaneously
As said before, you can connect to your Wi-Fi as many devices as you want. Of course this will have an effect on your speed, but still it is a great benefit. Imagine how much it would cost you to have a separate Wi-Fi connection for every device you own in your house! The cost would be really big anddeterring.
Now, let’s see some of the drawbacks of Wi-Fi:
- Limited radius of action
As you probably know if you have used Wi-Fi at least once in your life, the range of Wi-Fi is limited. With a standard equipment the typical range of a common network is only a few tens of meters. In fact, a typical home router with Wi-Fi in the room has a limited radius of action of up to 45 meters. In most houses, this range is more than ok, but if you have a big house with a yard, the simple router does not cover your needs.
For those who use Wi-Fi in public areas, the news is not so good. Wireless networks usually use the common encryption methods that are known to have major security weakness. Thus, you cannot actually know that you are 100% safe. This is really important for those who perform their financial transactions online since they can be potentially hacked.
- Quality Issues
As said above, one of the great disadvantages of Wi-Fi is that it has a limited range. Another issue, related to that is the fact that at high density Wi-Fi points that operate in the same channel, which usually happens apartment buildings and cafeterias that are very close to each other, these channels can interfere with each other and thus the end quality that the user receives can be significantly affected.
It is a fact that if you test the speed of a wired network and a wireless one, the latter one will be significantly slower. In many cases, this difference can be very big. This can cause many other problems like lower call quality when you use the Wi-Fi from your phone in order to communicate.
Even though, the Wi-Fi technology is not perfect and has many flaws, improvements are constantly made in order to fix all the above issues.
Now, let us see one fun fact about the Wi-Fi. There are over sixteen 802.11 Wi-Fi protocols. The first one was established in the 1990s and some of them are proposed for the future. If you want to find out more, The Smart Future has tried to describe them as accurately as possible. It is always good to have a deep knowledge on everything that you use in your everyday life, right?
