A ruling by the U. This was updated in with Inthe Wi-Fi Alliance formed as a trade association to hold the Wi-Fi trademark under which most products are sold. The yin-yang Wi-Fi logo indicates the certification of a product for interoperability. Wi-Fi ad-hoc mode[ edit ] Wi-Fi nodes operating in ad-hoc mode refers to devices talking directly to each other without the need to first talk to an access point also known as base station.

As of [update]the Wi-Fi Alliance consisted of more than companies from around the world. Manufacturers with membership in the Wi-Fi Alliance, whose products pass the certification process, gain the right to mark those products with the Wi-Fi logo.

Specifically, the certification process requires conformance to the IEEE Certification may optionally include tests of IEEE The lack of Wi-Fi certification does not necessarily imply that a device is incompatible with other Wi-Fi devices.

A dot with curved lines radiating from it is a common symbol for Wi-Fi, representing a point transmitting a signal. The combination of computer and interface controllers is called a station.

For all stations that share a single radio frequency communication channel, transmissions on this channel are received by all stations within range. A carrier wave is used to transmit the data. The data is organised in packets on an Ethernet link, referred to as " Ethernet frames ".

The service set can be local, independent, extended or mesh. The SSID is configured within the devices that are considered part of the network, and it is transmitted in the packets. Receivers ignore wireless packets from networks with a different SSID.

Versions[ edit ] There are many different versions of Wi-Fi: Equipment frequently support multiple versions of Wi-Fi. To communicate, devices must use a common Wi-Fi version.

The versions differ between the radio wavebands they operate on, the radio bandwidth they occupy, the maximum data rates they can support and other details. In general, lower frequencies have better range but have less capacity.

Some versions permit the use of multiple antennas, which permits greater speeds as well as reduced interference. Historically, equipment has listed the versions of Wi-Fi that it supports, but the Wi-Fi alliance has now standardised generational numbering so that equipment can indicate that it supports Wi-Fi 4 if the equipment supports The alliance have stated that the generational level 4, 5, or 6 can be indicated in the user interface when connected, along with the signal strength.

The coverage of one or more interconnected access points hotspots can extend from an area as small as a few rooms to as large as many square kilometres. Coverage in the larger area may require a group of access points with overlapping coverage.
