Full form for WiFi- WiFi stands for Wireless Fidelity
Full form for wifi -WiFi is a technology in which network connectivity is provided using radio waves.
An adapter for a WiFi connection is made a hotpot which is usually a wireless router and is connected to other devices such as laptops, mobiles, game consoles or PCs for Internet access.
After configuring WiFi one, it broadcasts 2.4GHz to 5GHz frequencies, depending on the size of the data.
Wi-Fi is the name of a popular wireless networking technology that uses radio signals for wireless high-speed Internet and network connections.
A common belief is that the term Wi-Fi comes from “Wireless Fidelity”, but this is not true. Wi-Fi is just a trademark phrase meaning IEEE 802.11x.
Typically for WiFi installed at home or office, a router is cabled to the Internet from an external ISP. Then this internet connection is configured in this router. Later all the devices connecting to this router get internet connectivity.
How Wi-Fi Networks Works?
The Full form for wifi – The easiest way to understand Wi-Fi, for example, is to take Wi-Fi in a home or office. It consists of a device that transmits wireless signals that are usually routers or hotspots.
It has a cable from an outside internet connection and it sets up the communication network through wireless signals on all the devices around it such as laptops or mobile.
Another method is a hotspot device, which shares the Internet with other devices through a wireless signal.
No matter how Wi-Fi is being used or what the source of its connection is, the result is always the same: a wireless signal so that other devices connect to the main transmitter for communication.
Most mobile devices, video game systems, and other standalone devices now also support Wi-Fi, making them easy to connect to wireless networks.
When a device establishes a Wi-Fi connection with a router, it can communicate with routers and other devices on the network.
However, to provide Internet access to connected devices it is necessary to first connect the router with the Internet.
WiFi Frequencies – Full form for wifi
A wireless network has a frequency level of 2.4 GHz or 5GHz, depending on the data the user sends. 802.11 Networking standard to some extent depends on the needs of the users.
The 802.11a network standard has data transmitted at a frequency level of 5GHz. In this, you can transmit a maximum of 54 megabytes of data per second.
The 802.11b network standard transmits data at a frequency level of 2.4GHz. It is slow speed and can transmit a maximum of 11 megabytes of data per second.
The 802.11g network standard transmits data at a frequency level of 2.4 GHz. But in this, you can transmit a maximum of 54 megabytes of data per second, as it uses OFDM coding.
Data is transmitted at a frequency level of 5 GHz in an 802.11n network standard. And you can transmit a maximum of 140 megabytes of data per second.
What are hotspots?-full form for Wifi
Term hotspots are used to define the area where WiFi access is available. This happens either at home or at a public place such as a restaurant or airport.
If you are using a laptop, it already has a wireless transmitter that connects to WiFi. You can also connect direct WiFi to mobile, but for the computer, you will need an external wireless adapter.
WIFI Advantage: Full form for wifi
a) Users of such wireless networks can access the Internet from any convenient location. These are the best for laptop or mobile.
b) Users can access the Internet at any time by connecting their mobile to the private and public wireless network of the home.
For example, most chain coffee shops or malls provide internet access to their customers for free.
d) Users connected to a wireless network can increase their productivity almost everywhere by connecting their laptop to a private or public wireless network.
e) For wireless networks, you do not need any physical cable which saves the cost of the network. Also, labor costs are also saved.
f) You do not need to spend extra on increasing the number of users in a wireless network compared to a wired connection. Multiple users are connected simultaneously to the same router.
Disadvantages of WiFi – Full form for wifi
Wireless networks are easier to hack than wired networks.
The range of Wi-Fi signals depends on the model of your route. Commonly used at home routers can range from 150 feet to 300 feet. If you want more range, then you need to buy Repeaters or Access Points
