What Does WiFi Stand For?

Though hasnt been approved officially, usually, WiFi stands forWireless Fidelityin our daily life.

[Solved] 9 Ways: Xfinity WiFi Connected but No Internet Access

Most people consider that WiFi is the abbreviation of wireless fidelity instead of its acronym.

The name WiFi, also written as Wi-Fi, Wifi, or wifi, has no further meaning.

It was never shortened for Wireless Fidelity officially.

Also, the Wi-Fi Alliance is called the Wireless Fidelity Alliance Inc in some publications.

What Does WiFi Mean?

Originally, WiFi was only used in place of the 2.4 GHz 802.11b standard.

attempting to stop confusion about wireless LAN interoperability.

How Does the Name WiFi Come From?

The WiFi Alliance hired Interbrand to create a name that was a little catchier than IEEE 802.11B Direct Sequence.

Interbrand also created the WiFi logo.

The yin-yang wifi logo means the certification of a product for interoperability.

How to Connect to a WiFi?

The combination of an interface controller and a computer is called a station.

Stations are identified by one or more media access control addresses (MAC address).

WiFi nodes usually operate in infrastructure mode where all communications go through a base station.

A service set is the set of all the devices that is related to a particular WiFi data pipe.

Those devices dont have to be on the same wavebands or channels.

A service set can be local, extended, mesh, independent, or a combination of them.

Each service set has a related identifier.

The 32-byte Service Set Identifier (SSID) identifies the particular online grid.

The SSID is configured within the devices that are considered a necessary part of the internet.

Each BSS is identified by a MAC address that is known as the BSSID.

How Does WiFi Work?

WiFi stations communicate with each other by sending data packets.

Blocks of data are individually sent and delivered over the radio.

As with all radio, this is done by the modulating and demodulating of carrier waves.

Different versions of WiFi make use of different techniques.

For other IEEE 802 LANs, stations come programmed with a globally unique 48-bit MAC address.

Therefore, each WiFi station has a unique address.

The MAC addresses are used to specify both the source and the destination of each packet.

WiFi establishes link-level connections that can be defined using both source and destination addresses.

If not, the transmission should be ignored.

Thus, users dont have to install a separatenetwork cardanymore.

thenetwork interface card(NIC) interrupts theCPUonly when applicable packets are received.

If the info is not addressed to a computer, the computers connection NIC card will ignore it.

Channels are used half-duplex.

It can be time-shared by multiple networks.

The use of the same channel indicates that the data bandwidth is also shared.

For instance, available data bandwidth to each equipment is halved when 2 stations are actively transmitting.

However, CSMA/CA sometimes can corrupt the transmitted data and require stations to re-transmit.

Occasionally, the re-transmission can severely reduce throughput.

OK, that is all about the WiFi it will talk about here.
