The standard and amendments provide the basis for wireless network products using the <a href="/wiki/Wi-Fi" title="Wi-Fi">Wi-Fi</a> brand and are the world's most widely used wireless computer networking standards. IEEE 802.11 is used in most home and office networks to allow laptops, printers, smartphones, and other devices to communicate with each other and access the <a href="/wiki/Internet" title="Internet">Internet</a> without connecting wires. IEEE 802.11 is also a basis for vehicle-based communication networks with <a href="/wiki/IEEE_802.11p" title="IEEE 802.11p">IEEE 802.11p</a>. The standards are created and maintained by the <a href="/wiki/Institute_of_Electrical_and_Electronics_Engineers" title="Institute of Electrical and Electronics Engineers">Institute of Electrical and Electronics Engineers</a> (IEEE) LAN/<a href="/wiki/Metropolitan_area_network" title="Metropolitan area network">MAN</a> Standards Committee (IEEE 802). The base version of the standard was released in 1997 and has had subsequent amendments. While each amendment is officially revoked when it is incorporated in the latest version of the standard, the corporate world tends to market to the revisions because they concisely denote the capabilities of their products. As a result, in the marketplace, each revision tends to become its own standard. 802.11x is a shorthand for "any version of 802.11", to avoid confusion with "802.11" used specifically for <a href="/wiki/IEEE_802.11_(legacy_mode)" title="IEEE 802.11 (legacy mode)">the original 1997 version</a>. IEEE 802.11 uses various frequencies including, but not limited to, 2.4 GHz, 5 GHz, 6 GHz, and 60 GHz frequency bands. Although IEEE 802.11 specifications list channels that might be used, the allowed <a href="/wiki/Radio_frequency" title="Radio frequency">radio frequency</a> spectrum availability varies significantly by regulatory domain. The protocols are typically used in conjunction with <a href="/wiki/IEEE_802.2" title="IEEE 802.2">IEEE 802.2</a>, and are designed to interwork seamlessly with <a href="/wiki/Ethernet"

Better or worse performance with higher or lower frequencies (channels) may be realized, depending on the environment. 802.11n and 802.11ax can use either the 2.4 GHz or 5 GHz band; 802.11ac uses only the 5 GHz band.

Since the 2.4 GHz band is heavily used to the point of being crowded, using the relatively unused 5 GHz band gives 802.11a a significant advantage. However, this high <a href="/wiki/Center_frequency" title="Center frequency">carrier frequency</a> also brings a disadvantage: the effective overall range of 802.11a is less than that of 802.11b/g. In theory, 802.11a signals are absorbed more readily by walls and other solid objects in their path due to their smaller wavelength, and, as a result, cannot penetrate as far as those of 802.11b. In practice, 802.11b typically has a higher range at low speeds (802.11b will reduce speed to 5.5 Mbit/s or even 1 Mbit/s at low signal strengths). 802.11a also suffers from interference,<a href="#cite_note-ACIisharmfull-52">[42]</a> but locally there may be fewer signals to interfere with, resulting in less interference and better throughput. <div class="mw-heading mw-heading3"><h3 id="802.11b">802.11b</h3>[<a href="/w/index.php?title=IEEE_802.11&action=edit&section=7" title="Edit section: 802.11b">edit</a>]</div> <link rel="mw-deduplicated-inline-style" href="mw-data:TemplateStyles:r1236090951"><div role="note" class="hatnote navigation-not-searchable">Main article: <a href="/wiki/IEEE_802.11b-1999" title="IEEE 802.11b-1999">IEEE 802.11b-1999</a></div> The 802.11b standard has a maximum raw data rate of 11 Mbit/s (Megabits per second) and uses the same media access method defined in the original standard. 802.11b products appeared on the market in early 2000, since 802.11b is a direct extension of the modulation technique defined in the original standard. The dramatic increase in throughput of 802.11b (compared to the original standard) along with simultaneous substantial price reductions led to the rapid acceptance of 802.11b as the definitive wireless LAN technology. Devices using 802.11b experience interference from other products operating in the 2.4 GHz band. Devices operating in the 2.4 GHz range include microwave ovens, Bluetooth devices, baby monitors, cordless telephones, and some amateur radio equipment.

Details of making b and g work well together occupied much of the lingering technical process; in an 802.11g network, however, the activity of an 802.11b participant will reduce the data rate of the overall 802.11g network.

One consequence is that stations can use only every fourth or fifth channel without overlap. Availability of channels is regulated by country, constrained in part by how each country <a href="/wiki/Frequency_allocation" title="Frequency allocation">allocates radio spectrum</a> to various services. At one extreme, Japan permits the use of all 14 channels for 802.11b, and 1–13 for 802.11g/n-2.4. Other countries such as Spain initially allowed only channels 10 and 11, and France allowed only 10, 11, 12, and 13; however, Europe now allow channels 1 through 13.<a href="#cite_note-CNAF-106">[91]</a><a href="#cite_note-ART-107">[92]</a> North America and some Central and South American countries allow only 1 through 11. <figure class="mw-default-size mw-halign-center" typeof="mw:File/Thumb"><a href="/wiki/File:2.4_GHz_Wi-Fi_channels_(802.11g_WLAN).svg" class="mw-file-description"><img src="//upload.wikimedia.org/wikipedia/commons/thumb/a/ac/2.4_GHz_Wi-Fi_channels_%28802.11g_WLAN%29.svg/720px-2.4_GHz_Wi-Fi_channels_%28802.11g_WLAN%29.svg.png" decoding="async" width="720" height="121" class="mw-file-element" srcset="//upload.wikimedia.org/wikipedia/commons/thumb/a/ac/2.4_GHz_Wi-Fi_channels_%28802.11g_WLAN%29.svg/1080px-2.4_GHz_Wi-Fi_channels_%28802.11g_WLAN%29.svg.png 1.5x, //upload.wikimedia.org/wikipedia/commons/thumb/a/ac/2.4_GHz_Wi-Fi_channels_%28802.11g_WLAN%29.svg/1440px-2.4_GHz_Wi-Fi_channels_%28802.11g_WLAN%29.svg.png 2x" data-file-width="2342" data-file-height="395" /></a><figcaption>Spectral masks for 802.11g channels 1–14 in the 2.4 GHz band</figcaption></figure> Since the spectral mask defines only power output restrictions up to ±11 MHz from the center frequency to be attenuated by −50 dBr, it is often assumed that the energy of the channel extends no further than these limits. It is more correct to say that the overlapping signal on any channel should be sufficiently attenuated to interfere with a transmitter on any other channel minimally, given the separation between channels. Due to the <a href="/wiki/Near%E2%80%93far_problem" title="Near–far problem">near–far problem</a> a transmitter can impact (desensitize) a receiver on a "non-overlapping" channel, but only if it is close to the victim receiver (within a meter) or operating above allowed power levels. Conversely, a sufficiently distant transmitter on an overlapping channel can have little to no significant effect. Confusion often arises over the amount of channel separation required between transmitting devices. 802.11b was based on <a href="/wiki/Direct-sequence_spread_spectrum" title="Direct-sequence spread spectrum">direct-sequence spread spectrum</a> (DSSS) modulation and utilized a channel bandwidth of 22 MHz, resulting in three "non-overlapping" channels (1, 6, and 11). 802.11g was based on OFDM modulation and utilized a channel bandwidth of 20 MHz. This occasionally leads to the belief that four "non-overlapping" channels (1, 5, 9, and 13) exist under 802.11g. However, this is not the case as per 17.4.6.3 Channel Numbering of operating channels of the IEEE Std 802.11 (2012), which states, "In a multiple cell network topology, overlapping and/or adjacent cells using different channels can operate simultaneously without interference if the distance between the center frequencies is at least 25 MHz."<a href="#cite_note-108">[93]</a> and section 18.3.9.3 and Figure 18-13. This does not mean that the technical overlap of the channels recommends the non-use of overlapping channels. The amount of inter-channel interference seen on a configuration using channels 1, 5, 9, and 13 (which is permitted in Europe, but not in North America) is barely different from a three-channel configuration, but with an entire extra channel.<a href="#cite_note-109">[94]</a><a href="#cite_note-adjacentchannels-110">[95]</a> <figure class="mw-default-size" typeof="mw:File/Thumb"><a href="/wiki/File:NonOverlappingChannels2.4GHz802.11-en.svg" class="mw-file-description"><img src="//upload.wikimedia.org/wikipedia/commons/thumb/4/4a/NonOverlappingChannels2.4GHz802.11-en.svg/220px-NonOverlappingChannels2.4GHz802.11-en.svg.png" decoding="async" width="220" height="272" class="mw-file-element" srcset="//upload.wikimedia.org/wikipedia/commons/thumb/4/4a/NonOverlappingChannels2.4GHz802.11-en.svg/330px-NonOverlappingChannels2.4GHz802.11-en.svg.png 1.5x, //upload.wikimedia.org/wikipedia/commons/thumb/4/4a/NonOverlappingChannels2.4GHz802.11-en.svg/440px-NonOverlappingChannels2.4GHz802.11-en.svg.png 2x" data-file-width="425" data-file-height="525" /></a><figcaption>802.11 non-overlapping channels in the 2.4 GHz ISM band</figcaption></figure> However, overlap between channels with more narrow spacing (e.g. 1, 4, 7, 11 in North America) may cause unacceptable degradation of signal quality and throughput, particularly when users transmit near the boundaries of AP cells.<a href="#cite_note-ciscodeployissues-111">[96]</a> <div class="mw-heading mw-heading3"><h3 id="Regulatory_domains_and_legal_compliance">Regulatory domains and legal compliance</h3>[<a href="/w/index.php?title=IEEE_802.11&action=edit&section=29" title="Edit section: Regulatory domains and legal compliance">edit</a>]</div> IEEE uses the phrase regdomain to refer to a legal regulatory region.

Some common 802.11 control frames include: <ul><li>Acknowledgement (ACK) frame: After receiving a data frame, the receiving station will send an ACK frame to the sending station if no errors are found. If the sending station does not receive an ACK frame within a predetermined period of time, the sending station will resend the frame.</li> <li>Request to Send (RTS) frame: The <a href="/wiki/IEEE_802.11_RTS/CTS" title="IEEE 802.11 RTS/CTS">RTS and CTS frames</a> provide an optional collision reduction scheme for access points with hidden stations. A station sends an RTS frame as the first step in a two-way handshake required before sending data frames.</li> <li>Clear to Send (CTS) frame: A station responds to an RTS frame with a CTS frame. It provides clearance for the requesting station to send a data frame. The CTS provides collision control management by including a time value for which all other stations are to hold off transmission while the requesting station transmits.</li></ul> <div class="mw-heading mw-heading3"><h3 id="Data_frames">Data frames</h3>[<a href="/w/index.php?title=IEEE_802.11&action=edit&section=33" title="Edit section: Data frames">edit</a>]</div> Data frames carry packets from web pages, files, etc. within the body.<a href="#cite_note-Frame_Types-116">[101]</a> The body begins with an <a href="/wiki/IEEE_802.2" title="IEEE 802.2">IEEE 802.2</a> header, with the Destination <a href="/wiki/Service_Access_Point" title="Service Access Point">Service Access Point</a> (DSAP) specifying the protocol, followed by a <a href="/wiki/Subnetwork_Access_Protocol" title="Subnetwork Access Protocol">Subnetwork Access Protocol</a> (SNAP) header if the DSAP is hex AA, with the <a href="/wiki/Organizationally_unique_identifier" title="Organizationally unique identifier">organizationally unique identifier</a> (OUI) and protocol ID (PID) fields specifying the protocol.
