WIFI Full Form – What Is WIFI, Definition, Meaning, Uses

WIFI Full Form Friends, in this article, we’ll look at the full form of the WIFI. This network is run by radio waves, similar to mobile networks. To utilize it, a wireless adapter is installed on the computer. Which decodes the signal of Wi-Fi. It achieves the system of internet communication in devices like mobiles, laptops, PCs, and tablets. You can access the Internet from any of your PCs by connecting to Wi-Fi.

The WIFI full form is Wireless Fidelity. WIFI allows an electrical device to send data or connect to the Internet utilizing the ISM radio band. It is a fundamental technology of wireless local area networks. Wi-Fi allows computers and other devices to communicate over a wireless network.

Wi-Fi network components are based on one of the 802.11 standards defined by the IEEE and adopted by the Wi-Fi Alliance. It provides a standard way to connect to wireless networks. WIFI is a trademark of Alliance and is used as a brand name for products employing the IEEE 802.11 standards.

Wi-Fi can be utilized on a broad variety of devices such as personal computers, video game consoles, smartphones, digital cameras, tablet computers, etc. You can use Wi-Fi to establish a hotspot within a range of 20 meters and 66 feet. It is less secure than a cable connection since the attacker does not need a physical connection to use Wi-Fi.

WiFi offers much higher peak data rates than 3G networks. But WiFi systems are not built to handle high-speed mobility since it operates on a large 20 MHz bandwidth. A key advantage of WiFi over WiMAX and 3G is the increased availability of terminal devices.

A great majority of laptops today include a built-in WiFi interface. Personal Data Assistants (PDAs), Cordless Phones, Cellular Phones, Cameras, and Media Players. Including WiFi, an interface is also being created for many devices.

WiFi is Half Duplex

All Wifi Networks are Dispute Based TDD Systems, where Access Point and Mobile Station are all VII to use the same channel. Due to shared media operation, all WiFi networks are half-duplex

There are equipment suppliers that advertise Wifi Mesh Configuration, but their implementations incorporate technologies that are not mentioned in the standards.

Channel Bandwidth

The WiFi Standards mandate fixed channel bandwidth of 25 MHz for 802.11b and 20 MHz for 802.11 A or G networks.

How does WIFI work?

Wi-Fi device makes connections between two devices without any wires, for which it employs Radio Frequency. This technology is based on various standards IEEE 802.11, whose frequency extends from 2.4GHz to 5GHz. Wireless Network An Access Point is required to connect any device and the area in which there is Wi-Fi is termed Hotspot.

Radio Signals

Radio transmissions are the keys that make WiFi networking possible. These radio signals emitted from WiFi antennae are picked up by WiFi receivers, such as PCs and cell phones, which are equipped with WiFi cards. Whenever a computer receives any signal within the range of a WiFi network which is normally 300 – 500 feet for antennae. The WiFi card reads the signals and so creates an internet connection between the user and the network without access.

Entry points, which include antennas and routers, are the principal sources that send and receive radio waves. Antennas work stronger and have a longer radio transmission with a radius of 300–500 ft, utilized in public spaces, while weak yet effective routers are more ideal for houses with radio transmissions of 100–150 ft. Is.

WiFi Cards

You can think of the WiFi card as the unseen card that connects your computer to the antenna for a direct connection to the Internet.

WiFi cards can be external or inside. If your computer doesn’t have a WiFi card installed, you can buy a USB antenna and connect it externally to your USB port or install an antenna-equipped expansion card directly into the computer as in the photo above. is indicated. For laptops, this card will be a PCMCIA card that you place into the PCMCIA slot on the laptop.

WiFi Hotspots

A WiFi hotspot is built by setting up an access point for an Internet connection. The access point transmits a wireless signal over a limited distance. It is normally around 300 feet. When a WiFi-capable device such as a Pocket PC encounters a hotspot, the device can connect to that network wirelessly.

Most hotspots are located in settings that are easily accessible to the public, such as airports, coffee shops, hotels, book stores, and college surroundings. 802.11b is the most used specification for hotspots around the world. The 802.11g standard is backward compatible.

11b. 11a uses a different frequency range and requires separate gear such as A, A/G, or A/B/G adapters. The largest public WiFi networks are provided by private Internet service providers (ISPs) (ISPs). They charge consumers who wish to access the Internet.

Hotspots are emerging rapidly over the planet. T-Mobile USA manages more than 4,100 hotspots located in public areas such as Starbucks, Borders, Kinkos, and the airline clubs of Delta, United, and US Airways. Even McDonald’s restaurants now feature WiFi hotspots.

Any notebook computer with integrated wireless, a wireless adapter installed to the motherboard by the manufacturer, or a wireless adaptor such as a PCMCIA card can use a wireless network. Also, all Pocket PC or Palm systems with CompactFlash, SD I/O compatibility, or built-in WiFi can access the hotspot.

Some hotspots require a WEP key to connect, which is deemed private and secure. Anyone with a WiFi card for an open connection can have access to that hotspot. Therefore to access the Internet under WEP, the user has to input the WEP Key Code.

WiFi Network Standards and Frequencies

  • The frequency level of WiFi is 2.4 GHz or 5 GHz. The 802.11 networking standard depends on the requirements of the user.
  • Data is carried at the frequency of 5 GHz in the 802.11a network standard. In this, there is data travel at the pace of a maximum of 54 MB per second.
  • Data is transmitted on the frequency of 2.4 GHz in the 802.11b network standard. In this, there is data travel at the pace of a maximum of 11 MB per second.
  • Data is transmitted at a frequency of 2.4 GHz in the 802.11g network standard. In this, there is data travel at the pace of a maximum of 54 MB per second.
  • Data is carried at the frequency of 5 GHz in the 802.11n network standard. In this, there is data travel at the pace of a maximum of 140 MB per second.
