Wireless local area network channels are frequently accessed using IEEE 802.11 protocols are sold mostly under the trademark WiFi. Other equipment also accesses the same channels, such as Bluetooth. The radio frequency (RF) spectrum is vital for wireless communications infrastructure.

Most operations on the RF spectrum require a license provided by a national regulatory body or the government.

The 802.11 standard provides several distinct radio frequency ranges for use in Wi-FI communications: 900 MHz 2.4 GHz, 3.6 GHz, 4.9 GHz, 5 GHz, 5.9 GHz and 60 GHz bands.[1][2][3] Each range is divided into a multitude of channels.

Countries apply their own regulations to the allowable channels, allowed users and maximum power levels within these frequency ranges. The ISM band ranges are also often used.[4]

Network operators should consult their local authorities as these regulations may be out of date as they are subject to change at any time.

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 Network operators should consult their local authorities as these regulations may be out of date as they are subject to change at any time.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.

To guarantee no interference in any circumstances the Wi-Fi protocol requires 16.25 to 22 MHz of channel separation (as shown below). The remaining 2 MHz gap is used as a guard band to allow sufficient attenuation along the edge channels. This guardband is mainly used to accommodate older routers with modem chipsets prone to full channel occupancy, as most modern WiFi modems are not prone to excessive channel occupancy.

While overlapping frequencies can be configured at a location 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):

However, the exact spacing required when the transmitters are not colocated depends on the protocol, the data rate selected, the distances and the electromagnetic environment where the equipment is used.[16]

The overall effect is that if there is considerable overlap between adjacent channels transmitters they will often interfere with each other. However, using every fourth or fifth channel by leaving three or four channels clear between used channels can cause less interference than sharing channels, and narrower spacing still can be used at further distances.[13][14]

3.65 GHz (802.11y)

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.

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

4.9–5.0 GHz (802.11j) WLAN

In Japan, 100 MHz of spectrum from 4900 MHz to 5000 MHz can be used for both indoor and outdoor connection starting from year 2002 [registration needed]. Originally, another spectrum 5030–5091 MHz was also available for use, however that have been re-purposed and cannot be use after year 2017.[15]

50 MHz of spectrum from 4940 MHz to 4990 MHz (WLAN channels 20–26) are in use by public safety entities in the United States. Within this spectrum space, there are two non-overlapping channels allocated, both with a width of 20 MHz. The most commonly used channels are 22 and 26.

In 2007, the FCC (United States) began requiring that devices operating on 5.250–5.350 GHz and 5.470–5.725 GHz must employ dynamic frequency selection (DFS) and transmit power control (TPC) capabilities. This is to avoid interference with weather-radar and military applications.[17] In 2010, the FCC further clarified the use of channels in the 5.470–5.725 GHz band to avoid interference with TDWR weather radar systems.[18] 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 5 GHz device operation (called the "New Rules"), which adds 160 and 80 MHz channel identifiers, and re-enables previously prohibited DFS channels, in Publication Number 905462.[19] 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 2 June 2016.[19]

Germany requires DFS and TPC capabilities on 5.250–5.350 GHz and 5.470–5.725 GHz as well; in addition, the frequency range 5.150–5.350 GHz is allowed only for indoor use, leaving only 5.470–5.725 GHz for outdoor and indoor use.[20]

Since this is the German implementation of EU Rule 2005/513/EC, similar regulations must be expected throughout the European Union.[21][22]

European standard EN 301 893 covers 5.15–5.725 GHz operation, and as of 2017-05-23 v2.1.1 has been adopted.[23]

Austria adopted Decision 2005/513/EC directly into national law.[24] The same restrictions as in Germany apply, only 5.470–5.725 GHz is allowed to be used outdoor and indoor.

Japan's use of 10 and 20 MHz-wide 5 GHz wireless channels is codified by Association of Radio Industries and Businesses (ARIB) document STD-T71, Broadband Mobile Access Communication System (CSMA).[26] Additional rule specifications relating to 40, 80, and 160 MHz channel allocation has been taken on by Japan's Ministry of Internal Affairs and Communications (MIC).[27]

In Brazil, the TPC use in 5.150–5.725 GHz band is optional. DFS is required only in the 5.470–5.725 GHz band.[28]

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).[10] As per AS/NZS 4268 B1 and B2, transmitters designed to operate in any part of 5250–5350 GHz and 5470–5725 GHz 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 5250–5350 MHz and 5470–5725 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 regulation differs from Australian.[29]

Singapore regulatory – IMDA requires DFS and TPC capabilities on 5.250–5.350 GHz above 100 mW (e.i.r.p.) and below or equal to 200 mW (e.i.r.p.), requires DFS capability on 5.250–5.350 GHz below or equal to 100 mW (e.i.r.p.), and requires DFS and TPC capabilities on 5.470–5.725 below or equal to 1000mW (e.i.r.p.). Operating 5.725–5.850 GHz above 1000mW and below or equal to 4000mW (e.i.r.p) shall be approved on exceptional basis.[30]

China MIIT expanded allowed channels as of 31 December 2012 to add UNII-1, 5150–5250 GHz, UNII-2, 5250–5350 GHz (DFS/TPC), similar to European standards EN 301.893 V1.7.1.[54]

{{anchor|5.9GHz}} 5.9 GHz (802.11p)

The 802.11p published on 15 July 2010, specifies WLAN in the licensed band of 5.9 GHz (5.850–5.925 GHz).

60 GHz (802.11ad/ay)

The 802.11ad/ay, also known as WiGig. This operates in 60 GHz ISM band.

{{60GHz WiGig channels}}

900 MHz (802.11ah)

802.11ah operates in sub-gigahertz unlicensed bands. Each world region supports different sub-bands, and the channels number depends on the starting frequency of the sub-band it belongs to. Thus, there is no global channels numbering plan, and the channels numbers are incompatible between world regions (and even between sub-bands of a same world region).

The following sub-bands are defined in the 802.11ah specifications:

Region Subband

(MHz)

920–928 1, 2, 4, 8
China755–779 1

Notes

{{note|B|B}}In the US, 802.11 operation on channels 12 and 13 is allowed under low power conditions. The 2.4 GHz Part 15 band in the US allows spread-spectrum operation as long as the 50 dB bandwidth of the signal is within the range of 2,400–2,483.5 MHz[56] which fully encompasses both channels 12 and 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.[57] Channels 12 and 13, however, are not normally used in order to avoid any potential interference in the adjacent restricted frequency band, 2,483.5–2,500 MHz,[58] which is subject to strict emission limits set out in 47 CFR § 15.205.[59] Per recent FCC Order 16-181, "an authorized access point device can only operate in the 2483.5–2495 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 2483.5–2495 MHz band when it is operating under the control of an authorized access point"[60]

In Canada, 12 channels are available for use, 11 of which at full power and the other (channel 12) is transmit power limited. Few devices, however, have a method to enable a lower powered channel 12.{{Citation needed|date=January 2018}}

{{note|C|C}}Channel 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 §19.4.2)
