In this digital world, imagining life without the internet is quite impossible. In this time, we often come across certain terms that we use in our daily lives frequently or hear other people using them. But many a time we are unaware of the exact meaning of such words. One such word is Wi-Fi.
What is Wi-Fi?
Wi-Fi is a common term used for a technology that provides wireless access to internet or network connections. This wireless networking technology makes use of radio waves to provide a high-speed internet connection to our devices.
In short, it means it means IEEE 802.11x.
Wi-Fi Alliance is the organization that has the ownership of the Wi-Fi registered trademark. According to the Wi-Fi Alliance, Wi-Fi is defined as, ” wireless local area network (WLAN) products that are based on the Institute of Electrical and Electronics Engineers’ (IEEE) 802.11 standards”.
A common misconception is that the full form of Wi-Fi is “wireless fidelity,” however this is not the case. Wi-Fi is simply a trademarked phrase that means IEEE 802.11x.
How to use Wi-Fi?
Now that we know what Wi-Fi means, let’s see how can we use this service for our benefit. Very commonly we hear people speaking about Wi-Fi connections at their place. But how do we get this connection?
In order to get a Wi-Fi connection at your place, you need to get a Wi-Fi router first. Besides this, you will also need to get an internet plan from a local Internet Service Provider (ISP). Once you have a router and you finish installing it and also an internet plan, you can use your router to create a Wi-Fi signal. All your devices can connect to this network and enjoy high-speed data connection.
A stepwise guide of getting a Wi-Fi connection for your home is mentioned below:
Step 1 – Get an Internet Service Plan: You need to get an internet plan from your local internet service provider. This depends mainly on the place where you stay. The internet subscription mainly comes with a monthly charge.
Step 2 – Get a Router: This again is an important step. The router you should choose depends on the size of your home and the internet service provider you have. Many reliable routers are there in the market. You should be careful while choosing the one for you. You should preferably choose a router that matches with the top speed of your internet service subscription. With this,
Step 3 – Get a modem: The modem acts as a link between your internet plan and the router. The choice of the modem again depends on the internet service provider that gives you the internet service and the size of your property.
Step 4 – Connect your modem with the cable outlet – Once you have all the things required to set up your network, move forward to the actual set up process. Connect your modem with the cable outlet with the help of the coaxial that was given to you with the modem. You should preferably put this in your living room or in some bedroom.
Step 5 – Connect the route to the modem: When you buy a Wi-Fi router, you get an ethernet port with it. This ethernet port is what you will have to use to connect the Wi-Fi router with the modem. Insert one end of the ethernet cable into the modem and connect the other end with the router.
Step 6 – Note the router’s SSID and password: SSID is the name that the network created by your Wi-Fi router will have. You will need this name and the password to log into the network with the help of the mobile of your router. You get the SSID name and the password on the backside or the bottom of your router or on the user manual.
Step 7 – Connect the router and modem to a power source: Connect the power cables of the modem and the router to their respective inputs. After this, insert the other end into a power outlet or a surge protector. Once you connect them with a power source, both the router and the modem will automatically turn on.
Step 8 – Set up the router: Most of the router these days have DIY installation process. These come with a user guide for the ease of the users. Following the user guide, set up your Wi-Fi network through the app of your router’s brand. You can set them up and do the required setting through the app. After you complete the above steps, you can name your network as per your choice and set up a password.
Once you are done with the above steps, your Wi-Fi network is ready to use. You can enjoy a strong able connection on your devices. All you need to do is to turn on the Wi-Fi on your device, search for the name of your network, enter the password and connect to your Wi-Fi network. You are all set to enjoy using high-speed internet on your mobile, tablets, laptops, PCs, etc.
Best Wi-Fi routers:
The market is full of with brands offering Wi-Fi routers that promise strong and reliable connections. From among those, some of the best options available for you to choose from are:
- Google Wi-Fi
- NetGear Orbi
- NetGear Orbi Pro
- TP Link DEco-M5
- Ubiquiti Amplifi HD
All of these routers have their own advantages and disadvantages. The one suitable for you depends on the size of your property, the number of devices you need to run and the level of control you want to have on your network.
How does Wi-Fi work?
If you want to know more in-depth about this amazing technology, here is how this technology works:
Wi-Fi makes use of radio waves and communication through a wireless Wi-Fi network is much like a two-way radio communication.
A device’s wireless adapter converts the data into a radio signal. It then transmits the signal through the antenna present on the device. The Wi-Fi router perceives these signals and decodes them. Henceforth, the router sends this decoded information to the internet using a physical, wired ethernet connection. The flow of information can be in reverse direction as well. That is the router may also receive information from the internet, convert it into a radio signal and transmit it to the computer’s adapter.
The radios used in this wireless communication are very much like those used in cell phones, etc. for communication. They can also receive data in binary form and convert it into radio waves. Or they may receive radio signals and convert them into the binary format of 0s and 1s.
However, the difference between Wi-Fi radios and the radios used in mobiles and other devices is that they transmit information at a frequency which is very high for cell phones, television, etc. They transmit information at frequencies of 2.4 GHz or 5GHz. Such a high frequency enables more data to be carried. Besides these, they make the use of 802.11 networking standards.
Difference Between Wi-Fi and the Internet:
Very often we tend to mistake the internet and Wi-Fi to be the same. But there is a very clear difference between these two commonly used terms.
Internet is a public network that you use to access information, connect to webpages, visit websites or such stuff. You can get access to this network through an ethernet cable or a Wi-Fi router. Wi-Fi, on the other hand, is a technology that helps you to wirelessly connect to a network. You can connect to the network with the help of Wi-Fi. Therefore, Wi-Fi can be understood as a gateway to connect to and access the internet.
Share a Phone’s networK:
Very often we talk about sharing our mobile network with the help of hotspot and Wi-Fi. You can do this following a set of simple steps:
- Go to the settings and Turn on the portable hotspot in the mobile whose network has to be shared.
- On the other device, turn on the Wi-Fi.
- Scan the available networks that can be connected to.
- Look for the name of the network that you know the password on.
- Tap on the network’s name.
- Enter the password of the network. In case you don’t know the password, you can find it in the settings of the other device.
- Tap on connect and you are all set to use the mobile’s network on your cell phone.
