WIFI: Wireless Fidelity

WIFI is an electronic device that is used to establish the connection for the internet with the help of the ISM bands of radio and for the data transfer as well. It is also commonly termed as Wi-Fi and it is a wireless technology purposed to leverage the local area. When we talk about the wireless network, Wi-Fi sets the medium between the computer and the other devices and establishes a connection between them to communicate with each other.

You must be aware of the IEEE standards. 802.11 standards is also a standard that was developed by IEEE. It was then adopted by the Wi-Fi alliance and thus all the network components of Wi-Fi are based on this standard.

What is the use of these standards? When you are making a connection, it can't be for one but all. So IEEE standards provide the standard way to connect with the wireless network.

For the Wi-Fi alliance, Wi-Fi is its trademark. Whatever products use the IEEE 802.11 standards, it is used as the brand name for all such products. Wi-Fi enables digital access for the user in a very easy manner.

Technical Specification of WiFi

As we have studied above that WiFi is based on the specifications of IEEE 802.11 standards. There can be five different Wi-Fi standards. It is in this order,

1. 802.11a – it provides up to 54 Mbps and 5GHz bandwidth.
2. 802.11b – its unofficial retronym is Wi-Fi 1. It provides a range of 120 feet indoor.
3. 802.11g – it provides up to 54 Mbps and 2.4 GHz bandwidth. It provides a range of 300 feet outdoor.
4. 802.11n – it gives better performance with more reliability, speed and also increases the range for the wireless transmissions.
5. 802.11ac – it provides 433 Mbps up to some gigabits per second. It is faster than all the previous standards.

Pros of WiFi

• It can be very helpful for devices such as PCs, video game consoles, tablet computers, etc. for the connection purpose.
• A range of 20 meters of the hotspot can be created with the help of WiFi.

Cons of WiFi

If the third person wants to use your Wi-Fi hotspot, it can easily connect to it as it doesn’t require any physical connection to use the Wi-Fi. Therefore, Wi-Fi is less secure than those of wired connections.
