Wi-Fi – A Wireless Technology That Helps Us to Connect Our Electronic Devices
Wireless Fidelity or Wi-Fi as we all know it is the wireless technology that helps us to connect our electronic devices like computers, smartphones, tablets and other devices with the internet.
Wi-Fi is in the form of radio signal that is sent from a wireless router to the nearby devices, this device translates the signal into data which is seen and used by us. On the other hand this device gives out a radio signal back to the router, which gets connected to the internet through a wire or a cable.
- What is a Wi-Fi Network?
In simple words a Wi-Fi network is an internet connection that can be shared by many devices either inside a home or a business with the help of a wireless router. The router can be directly connected to your internet modem which can act as a hub to broadcast the internet signals to all the Wi-Fi enabled devices that are present. This gives us the flexibility to be connected to the internet within the chosen network coverage area.
- How does Wi-Fi Work?
As we all know that Wi-Fi uses radio waves or signals to transfer the data to our Wi-Fi enabled devices like smartphones, computers, tablets & T.V. for they communicate over airwaves with each other. Our devices & personal information becomes vulnerable to hackers, cyber-attacks & other threats if we connect to any public Wi-Fi networks at coffee shops, airports & train stations. It is always good to connect to a wireless network that is password protected or a personal hotspot.
- Types of Wi-Fi Connections:
Our options for connecting wirelessly at home are increasing as mobile networks are expanding into the home internet realm. Although there are many advantages and disadvantages with each type of wireless connection such as speed, strength of signal & many more.
Wire line Router- Many homes uses a wireless router to access the internet these days. The advantages of this are its easy to setup, mobility within range of Wi-Fi access point (router) and the ability to connect many devices. The disadvantages of this are reduced speed and limited bandwidth if many devices are connected to the same Wi-Fi network.
Mobile Hotspot v/s Wi-Fi Network – Nowadays mobile & dedicated hotspots are becoming a popular way of connecting safely on the go. Wi-Fi network on the other hand is best suited for your home & office. The most common hotspot devices are smartphones and jetpacks, the most common Wi-Fi network devices are routers and modems.
Both have their advantages & disadvantages, but if you are travelling then mobile hotspot or jetpack device is useful and if you are browsing internet in your home then Wi-Fi network is very useful.
If you are accessing data using your mobile hotspot then this will drain the battery of your smart phone, on the other hand if you are using a Wi-Fi network or jetpack device then your smartphone battery does not get depleted easily. The only disadvantage of a jetpack device is that it has to be purchased separately with a separate plan from the mobile service provider.
- How to Get Wi-Fi at Home?
There are several ways to get wireless connection at home. It mostly depends on your geographical location and availability. If you are living in an urban and suburban area then you will be getting 5G home internet service at every corner of your locality. On the other hand rural areas will be getting 4G LTE home internet services.
If you have a wired internet service, you can setup your own Wi-Fi network at home, if you connect a router to your modem & you will be able to share your internet connection to all your Wi-Fi enabled devices that are within the range. The maximum download speed for Wi-Fi service providers can go upto 62.45 Mbps.
Along with Wi-Fi we should also know about two more aspects namely:
Broadband- This is the transmission of wide bandwidth data over a high speed internet connection.
Bandwidth- This is the maximum amount of data that is transmitted over an internet connection in a given amount of time.
To conclude Wi-Fi is essential for home internet services and mobile hotspot is essential for outdoor internet services.
