Wireless LAN (WLAN) channels are frequently accessed using IEEE 802.11 protocols. The 802.11 standard provides several radio frequency bands for use in Wi-Fi communications, each divided into a multitude of frequency channels numbered at 5ย MHz spacing (except in the 45/60ย GHz band, where they are 0.54/1.08/2.16ย GHz apart) between the centre frequency of the channel. The standards allow for channels to be bonded together into wider channels for faster throughput.

860/900 MHz (802.11ah)

edit

802.11ah operates in sub-gigahertz unlicensed bands. There are two main bands in use, with Europe mainly using 860ย MHz, and the rest of the world mostly using 900ย MHz.

edit

Each world region supports different sub-bands, and the channel numbers depend on the starting frequency on the sub-band it belongs to. Therefore there is no global channel numbering plan, and the channel numbers are incompatible between world regions (and even between sub-bands of a same world region). However, for the purposes of illustration, the following table lists all the worldwide permitted frequencies with the channel numbers assigned to the region with the largest number of permitted frequencies, the United States.

Notes:

^AIn the 2.4ย GHz bands bonded 40ย MHz channels are uniquely named by the primary and secondary 20ย MHz channels, e.g. 9+13. In the 5ย GHz bands they are denoted by the center of the wider band and the primary 20ย MHz channel e.g. 42[40]

^BIn the US, 802.11 operation on channels 12 and 13 is allowed under low-power conditions. The 2.4ย GHz Part 15 band in the US allows spread-spectrum operation as long as the 50ย dB bandwidth of the signal is within the range of 2,400โ€“2,483.5ย MHz,[12] which fully encompasses channels 1 through 13. A Federal Communications Commission (FCC) document clarifies that only channel 14 is forbidden and that low-power transmitters with low-gain antennas may operate legally in channels 12 and 13.[13] Channels 12 and 13 are nevertheless not normally used in order to avoid any potential interference in the adjacent restricted frequency band, 2,483.5โ€“2,500ย MHz,[14] which is subject to strict emission limits set out in 47 CFR ยงย 15.205.[15] Per recent FCC Order 16โ€“181, "an authorized access point device can only operate in the 2483.5โ€“2495 MHz band when it is operating under the control of a Globalstar Network Operating Center and that a client device can only operate in the 2483.5โ€“2495 MHz band when it is operating under the control of an authorized access point"[16]

^CChannel 14 is valid only for DSSS and CCK modes (Clause 18 a.k.a. 802.11b) in Japan. OFDM (i.e., 802.11g) may not be used. (IEEE 802.11-2007 ยงย 19.4.2)

Nations apply their own RF emission regulations to the allowable channels, allowed users and maximum power levels within these frequency ranges. Network operators should consult their local authorities as these regulations may be out of date as they are subject to change at any time. Most of the world will allow the first thirteen channels in the spectrum.

Interference happens when two networks try to operate in the same band, or when their bands overlap. The two modulation methods used have different characteristics of band usage and therefore occupy different widths:

  • The DSSS method used by legacy 802.11 and 802.11b (and the 11b-compatible rates of 11ย g) occupies 22ย MHz of bandwidth. This is from the 11ย MHz chip rate used by the coding system. No guard band is prescribed;[17] the channel definition provides 3ย MHz between 1, 6, and 11.
  • The OFDM method used by 802.11g and 802.11n occupies a bandwidth of 16.25ย MHz. The nameplate bandwidth is set to be 20ย MHz, rounding up to a multiple of channel width and providing some guard band for signal to attenuate along the edge of the band.[18] This guardband is mainly used to accommodate older routers with modem chipsets prone to full channel occupancy, as most modern Wiโ€‘Fi routers are not prone to excessive channel occupancy.
Graphical representation of Wireless LAN channels in 2.4ย GHz band. Channels 12 and 13 are customarily unused in the United States. As a result, the usual 20ย MHz allocation becomes 1/6/11, the same as 11b.

While overlapping frequencies can be configured at a location and will usually work, it can cause interference resulting in slowdowns, sometimes severe, particularly in heavy use. Certain subsets of frequencies can be used simultaneously at any one location without interference (see diagrams for typical allocations). The consideration of spacing stems from both the basic bandwidth occupation (described above), which depends on the protocol, and from attenuation of interfering signals over distance. In the worst case, using every fourth or fifth channel by leaving three or four channels clear between used channels causes minimal interference, and narrower spacing still can be used at further distances.[19][20] The "interference" is usually not actual bit-errors, but the wireless transmitters making space for each other. Interference resulting in bit-error is rare.[20] The requirement of the standard is for a transmitter to yield when it decodes another at a level of 3ย dB above the noise floor,[21] or when the non-decoded noise level is higher than a threshold Pth which, for Wi-Fi 5 and earlier, is between -76 and -80ย dBm.[20]

As shown in the diagram, bonding two 20ย MHz channels to form a 40ย MHz channel is permitted in the 2.4ย GHz bands. These are generally referred to by the centres of the primary 20ย MHz channel and the adjacent secondary 20ย MHz channel (e.g. 1+5, 9+13, 13โ€“9, 5โ€“1). The primary 20ย MHz channel is used for signalling and backwards compatibility, the secondary is only used when sending data at full speed.[22]

3.65 GHz (802.11y)

edit

Except where noted, all information taken from Annex J of IEEE 802.11y-2008

This range is documented as only being allowed as a licensed band in the United States. However, not in the original specification, under newer frequency allocations from the FCC, it falls under the 3.55โ€“3.7 GHz Citizens Broadband Radio Service band. This allows for unlicensed use, under Tier 3 GAA rules, provided that the user doesn't cause harmful interference to Incumbent Access users or Priority Access Licensees and accepts all interference from these users,[23] and also follows all the technical requirements in CFR 47 Part 96 Subpart E.

A 40ย MHz band is available from 3655 to 3695ย MHz. It may be divided into eight 5ย MHz channels, four 10ย MHz channels, or two 20ย MHz channels.

The division into 5ย MHz channels consumes all eight possible channel numbers, and so (unlike other bands) it is not possible to infer the width of a channel from its number. Instead each wider channel shares its channel number with the 5ย MHz channel just above its mid frequency:

  • channel 132 can be either 3660-3665 or 3655-3665;
  • channel 133 can be either 3665-3670 or 3655-3675;

and so on.

In Japan since 2002, 80ย MHz of spectrum from 4910 to 4990ย MHz has been available for both indoor and outdoor use, once registered.

Until 2017, an additional 60ย MHz of spectrum from 5030 to 5090ย MHz was available for registered use, however it has since been re-purposed and can no longer be used.[24]

50ย MHz of spectrum from 4940 to 4990ย MHz (WLAN channels 20โ€“26) are in use by public safety entities in the United States. Within this spectrum there are two non-overlapping channels allocated, each 20ย MHz wide. The most commonly used channels are 22 and 24.

DFS and TPC

edit

Source:[57]

United States

edit

In 2007, the FCC (United States) began requiring that devices operating in the bands of 5.250โ€“5.350ย GHz and 5.470โ€“5.725ย GHz must employ dynamic frequency selection (DFS) and transmit power control (TPC) capabilities. This is to avoid interference with weather-radar and military applications.[58] In 2010, the FCC further clarified the use of channels in the 5.470โ€“5.725ย GHz band to avoid interference with Terminal Doppler Weather Radar (TDWR).[59] In FCC parlance, these restrictions are now referred to collectively as the Old Rules. On 10 June 2015, the FCC approved a new ruleset for 5ย GHz device operation (called the New Rules), which adds 160 and 80ย MHz channel identifiers, and re-enables previously prohibited DFS channels, in Publication Number 905462.[60] This FCC publication eliminates the ability for manufacturers to have devices approved or modified under the Old Rules in phases; the New Rules apply in all circumstances as of 2ย Juneย 2016.[60]

United Kingdom

edit

The UK's Ofcom regulations for unlicensed use of the 5ย GHz band is similar to Europe, except that DFS is not required for the frequency range 5.725โ€“5.850ย GHz and the SRD maximum mean e.i.r.p is 200ย mW instead of 25ย mW.[61]

Additionally, 5.925โ€“6.425ย GHz is also available for unlicensed use, as long as it is used indoors with an SRD of 250ย mW.

Germany

edit

Germany requires DFS and TPC capabilities on 5.250โ€“5.350ย GHz and 5.470โ€“5.725ย GHz as well; in addition, the frequency range 5.150โ€“5.350ย GHz is allowed only for indoor use, leaving only 5.470โ€“5.725ย GHz for outdoor and indoor use.[62]

Since this is the German implementation of EU Rule 2005/513/EC, similar regulations must be expected throughout the European Union.[29][30]

European standard EN 301 893 covers 5.15โ€“5.725ย GHz operation, and as of 23ย Mayย 2017 v2.1.1 has been adopted.[63] 6ย GHz can now be used.[64]

Austria

edit

Austria adopted Decision 2005/513/EC directly into national law.[65]

Japan

edit

Japan's use of 10 and 20ย MHz-wide 5ย GHz wireless channels is codified by Association of Radio Industries and Businesses (ARIB) document STD-T71, Broadband Mobile Access Communication System (CSMA).[66] Additional rule specifications relating to 40, 80, and 160ย MHz channel allocation has been taken on by Japan's Ministry of Internal Affairs and Communications (MIC).[67]

Brazil

edit

In Brazil, the use of TPC is required in the 5.150โ€“5.350ย GHz and 5.470โ€“5.725ย GHz bands is required, but devices without TPC are allowed with a reduction of 3ย dB.[68] DFS is required in the 5.250โ€“5.350ย GHz and 5.470โ€“5.725ย GHz bands, and optional in the 5.150โ€“5.250ย GHz band.[69]

Australia

edit

As of 2015, some of the Australian channels require DFS to be utilised (a significant change from the 2000 regulations, which allowed lower power operation without DFS).[9] As per AS/NZS 4268 B1 and B2, transmitters designed to operate in any part of 5250โ€“5350ย MHz and 5470โ€“5725ย MHz bands shall implement DFS in accordance with sections 4.7 and 5.3.8 and Annex D of ETSI EN 301 893 or alternatively in accordance with FCC paragraph 15.407(h)(2). Also as per AS/NZS 4268 B3 and B4, transmitters designed to operate in any part of 5250โ€“5350ย MHz and 5470โ€“5725ย MHz bands shall implement TPC in accordance with sections 4.4 and 5.3.4 of ETSI EN 301 893 or alternatively in accordance with FCC paragraph 15.407(h)(1).

New Zealand

edit

New Zealand regulation differs from Australian.[70]

Philippines

edit

In the Philippines, the National Telecommunications Commission (NTC) allows the use of 5150ย MHz to 5350ย MHz and 5470ย MHz to 5850ย MHz frequency bands indoors with an effective radiated power (ERP) not exceeding 250ย mW. Indoor Wireless Data Network (WDN) equipment and devices shall not use external antenna. All outdoor equipment/radio station whether for private WDN or public WDN shall be covered by appropriate permits and licenses required under existing rules and regulations.[56]

Singapore

edit

Singapore regulation requires DFS and TPC to be used in the 5.250โ€“5.350ย GHz band to transmit more than 100ย mW effective radiated power (EIRP), but no more than 200ย mW, and requires DFS capability on 5.250โ€“5.350ย GHz below or equal to 100ย mW EIRP, and requires DFS and TPC capabilities on 5.470โ€“5.725 below or equal to 1000ย mW EIRP. Operating 5.725โ€“5.850ย GHz above 1000ย mW and below or equal to 4000ย mW EIRP shall be approved on exceptional basis.[43]

South Korea

China

edit

China MIIT expanded allowed channels as of 31ย Decemberย 2012 to add UNII-1, 5150โ€“5250ย MHz, UNII-2, 5250โ€“5350ย MHz (DFS/TPC), similar to European standards EN 301.893 V1.7.1.[72] China MIIT expanded allowed channels as of 3ย Julyย 2017 to add U-NII-3, 5725โ€“5850ย MHz.[73]

Indonesia

edit

Indonesia allows use of the band 5150โ€“5350 MHz with maximum EIRP of 200 mW (23 dBm) and maximum bandwidth of 160 MHz, and the band 5725โ€“5825 MHz with the same maximum EIRP and maximum bandwidth of 80 MHz for indoor use. Outdoors, use of the band 5725โ€“5825 MHz with maximum EIRP of 4 W (36 dBm) is allowed, with a maximum bandwidth of 20 MHz.[74][75]

India

edit

In exercise of powers conferred by the Indian Telegraph Act, 1885 and Indian Wireless Telegraphy Act, 1933,[76] the Government of India made the Use of Wireless Access System including Radio Local Area Network in 5ย GHz band (Exemption from Licensing Requirement) Rules, 2018.[77][78]

These rules exempted the spectrum of 5150โ€“5250 MHz, 5250โ€“5350 MHz, and 5725โ€“5875 MHz in the 5 GHz band from licensing, allowing their use for establishing wireless access systems in both indoor and outdoor environments.[79] For transmitters operating in the 5150โ€“5250 MHz, 5250โ€“5350 MHz, and 5470โ€“5725 MHz bands, out-of-band emissions were limited to an e.i.r.p. of โˆ’27 dBm/MHz. For transmitters operating in the 5725โ€“5875 MHz band, emissions within 10 MHz of the band edge were limited to an e.i.r.p. of โˆ’17 dBm/MHz, while anything beyond this range was limited to โˆ’27 dBm/MHz.[78] Additionally, it defined procedures for interference and specified the standards to be followed by wireless equipment.[80][81]

5.9 GHz (802.11p)

edit

The 802.11p amendment published on 15 July 2010, specifies WLAN in the licensed band of 5.9ย GHz (5.850โ€“5.925ย GHz).

6 GHz (802.11ax/be/bn)

edit

The Wi-Fi Alliance has introduced the term Wiโ€‘Fi 6E to identify and certify IEEE 802.11ax devices that support this new band, which is also used by Wi-Fi 7 (IEEE 802.11be) and Wi-Fi 8 (IEEE 802.11bn).

Notes

edit

  • โ†‘ Channel 2: The 802.11ax specification defines a special Operating Class 136[88] starting at 5925Mhz at 20Mhz wide containing channel 2.[89][90] Not all regions reserved frequencies this low for 6Ghz. European regulations allow the first channel to begin at 5945Mhz.[91] Others such as New Zealand, India begin at 5925ย MHz.[92] Thus, the separate operating class was created to allow flexibility for any regions (where regulations allow) to make use of channel 2, however the industry considers this channel as a reserved guard band[93] to ensure there is no possibility of overlap with the 5Ghz band or other adjacent spectrum reservations.

Initialisms (precise definition below):

  • LPI: low-power indoor
  • VLP: very-low-power

United States

edit

On 23 April 2020, the FCC voted on and ratified a Report and Order[94][95] to allocate 1.2ย GHz of unlicensed spectrum in the 6ย GHz band (5.925โ€“7.125ย GHz) for Wi-Fi use.

Standard power

edit

Standard-power access points are permitted indoors and outdoors at a maximum EIRP of 36ย dBm in the U-NII-5 and U-NII-7 sub-bands with automatic frequency coordination (AFC).

Low-power indoor (LPI) operation

edit

Note: Partial channels indicate channels that span UNII boundaries, which is permitted in 6ย GHz LPI operation. Under the proposed channel numbers, the U-NII-7/U-NII-8 boundary is spanned by channels 185 (20ย MHz), 187 (40ย MHz), 183 (80ย MHz), and 175 (160ย MHz). The U-NII-6/U-NII-7 boundary is spanned by channels 115 (40ย MHz), 119 (80ย MHz), and channel 111 (160ย MHz).

For use in indoor environments, access points are limited to a maximum EIRP of 30ย dBm and a maximum power spectral density of 5ย dBm/MHz. They can operate in this mode on all four U-NII bands (5,6,7,8) without the use of automatic frequency coordination. To help ensure they are used only indoors, these types of access points are not permitted to be connectorized for external antennas, weather-resistant, or run on battery power.[95]:โ€Š41โ€Š

Very-low-power devices

edit

The FCC may issue a ruling in the future on a third class of very low power devices such as hotspots and short-range applications.

Canada

edit

In November 2020, the Innovation, Science and Economic Development (ISED) of Canada published "Consultation on the Technical and Policy Framework for Licence-Exempt Use in the 6ย GHz Band".[96] They proposed to allow licence-exempt operations in the 6ย GHz spectrum for three classes of radio local area networks (RLANs):

Standard power

edit

For indoor and outdoor use. Maximum EIRP of 36ย dBm and maximum power spectral density (PSD) of 23ย dBm/MHz. Should employ Automated Frequency Coordination (AFC) control.

Low-power indoor (LPI)

edit

For indoor use only. Maximum EIRP of 30ย dBm and maximum PSD of 5ย dBm/MHz.

Very-low-power (VLP)

edit

For indoor and outdoor use. Maximum EIRP of 14ย dBm and maximum PSD of -5ย dBm/MHz. (-8 dBm/MHz was in consultation, -5 dBm/MHz was finalized)

Europe

edit

ECC Decision (20)01 from 20 November 2020[97] allocated the frequency band from 5945 to 6425ย MHz (corresponding almost to the US U-NII-5 band) for use by low-power indoor and very-low-power devices for Wireless Access Systems/Radio Local Area Networks (WAS/RLAN), with a portion specifically reserved for rail networks and intelligent transport systems.[98]

India

edit

On January 20, 2026, the Ministry of Communications, Government of India, through a Gazette notification, has officially de-licensed the lower portion of the 6 GHz spectrum (from 5925 MHz to 6425 MHz) for the Use of Low Power and Very Low Power Wireless Access System. [99] [100]

Low-power indoor (LPI)

edit

For indoor use only. Maximum EIRP of 30ย dBm and maximum PSD of 11ย dBm/MHz.

Very-low-power outdoor (VLP)

edit

For indoor and outdoor use. Maximum EIRP of 14ย dBm and maximum PSD of 1ย dBm/MHz.

United Kingdom

edit

Since July 2020, the UK's Ofcom permitted unlicensed use of the lower 6ย GHz band (5945 to 6425ย MHz, corresponding to the US U-NII-5 band) by Low Power indoor and Very Low Power indoor and mobile Outdoor device.[101][102]

Australia

edit

In April 2021, Australia's ACMA opened consultations for the 6ย GHz band. The lower 6ย GHz band (5925 to 6425ย MHz, corresponding to the US U-NII-5 band) was approved for 250ย mW EIRP indoors and 25ย mW outdoors on March 4, 2022.[103] From 1 October 2025 the approved range was increased by 160ย MHz to 5925โ€“6585ย MHz,[104] allowing for an additional 160ย MHz / 320ย MHz channel in the 6ย GHz band for Wi-Fi use. The ACMA intends to allocate the 6585โ€“7100ย MHz portion of the band to mobile telephony use, but is delaying that allocation while it monitors spectrum arrangements in other major markets that drive the manufacturing of mobile network equipment,[105] potentially allowing for additional spectrum to be allocated to Wi-Fi at a later date.

This is in line with the following ACMA decisions on the future of the upper 6ย GHz spectrum in Australia published in the December 2024 consultation outcomes paper:[106]

โ€ข Add 6425โ€“6585 MHz to the LIPD class licence to support RLAN (Radio Local Area Network) use. This work is intended to be implemented as part of our task to remake the instrument prior to its sunsetting in October 2025. We are aiming to consult on updates to the LIPD class licence in early 2025.

โ€ข Plan for 6585โ€“7100 MHz in defined population areas for potential WA WBB (Wide Area Wireless Broadband) use, but not commence implementation of these arrangements until certainty around progress towards international equipment markets can be provided. This planning will include determination of defined areas in consultation with stakeholders.

โ€ข Once defined areas have been determined, make provision for apparatus licensed access in 6585โ€“7100ย MHz outside those areas to enable the deployment of local area WBB services (either IMT or RLAN-based technologies).''

Low-power indoor (LPI)

edit

For indoor use only. Maximum EIRP of 250ย mW. The power spectral density must not be greater than 12.5ย mW EIRP per 1ย MHz.

Very-low-power (VLP)

edit

For indoor and outdoor use. Maximum EIRP of 25ย mW. The power spectral density must not be greater than 1.25ย mW EIRP per 1ย MHz.

Japan

edit

In September 2022, the Ministry of Internal Affairs and Communications announced amendments to the ministerial order and notices related to the Radio Act.[107]

Low-power indoor (LPI)

edit

For indoor use only. Maximum EIRP of 200ย mW.

Very-low-power (VLP)

edit

For indoor and outdoor use. Maximum EIRP of 25ย mW.

Taiwan

edit

Since August 2023, Taiwan's NCC permitted unlicensed use of the lower 6ย GHz band (5945 to 6425ย MHz, corresponding to the US U-NII-5 band) by Low Power indoor and Very Low Power indoor and mobile Outdoor device.[108]

Russia

edit

In December 2022, Russian State Commission for Radio Frequencies authorised 6ย GHz operation for low-power indoor (LPI) use with transmitter power control (TPC) limited to maximum EIRP of 200ย mW and maximum PSD of 10ย mW/MHz, and very low power (VLP) indoor and mobile outdoor use with maximum EIRP of 25ย mW and maximum PSD of 1.3ย mW/MHz.[109]

Singapore

edit

In May 2023, Singapore's IMDA will amend its Regulations to allocate the radio frequency spectrum 5,925ย MHz โ€“ 6,425ย MHz for Wi-Fi use in Singapore.[110]

Philippines

edit

On May 23, 2024, the Philippines' National Telecommunications Commission (NTC) is considering the use of 5925ย MHz to 6425ย MHz frequency bands indoors with an effective radiated power (ERP) not exceeding 250ย mW and outdoors with an effective radiated power not exceeding 25ย mW.[111] On July 5, 2024, the NTC has released Memorandum Circular No. 002-07-2024, allowing 6ย GHz Wi-Fi use, with the added restriction that the use on unmanned aircraft systems is prohibited.[112]
