2.4 GHz radio use. There are several uses of the 2.4 GHz ISM radio band. Interference may occur between devices operating at 2.4 GHz. This article details the different users of the 2.4 GHz band, how they cause interference to other users and how they are prone to interference from other users.
2.4 GHz (802.11b/g/n/ax/be) 14 channels are designated in the 2.4 GHz range, spaced 5 MHz apart from each other except for a 12 MHz space before channel 14. [2] . The abbreviation F 0 designates each channel's fundamental frequency . Interference happens when two networks try to operate in the same band, or when their bands overlap.
#F 0 (mhz)Dsss(frequency Range (mhz))Dsss(channel 22 Mhz)1424842473–2495141324722461–2483111224672456–2478111124622451–24731140 MHz channels in 2.4 GHz. The 2.4 GHz ISM band is fairly congested. With 802.11n, there is the option to double the bandwidth per channel to 40 MHz (fat channel) which results in slightly more than double the data rate. However, in North America, when in 2.4 GHz, enabling this option takes up to 82% of the unlicensed band.
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. Each range is divided into a multitude of channels. In the standards, channels are numbered at 5 MHz spacing within a band (except in the 60 GHz band, where they are 2.16 GHz ...
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 radio frequency spectrum availability varies significantly by regulatory domain.
Wi-Fi 6 covers frequencies in license-exempt bands between 1 and 7.125 GHz, including the commonly used 2.4 GHz and 5 GHz, as well as the broader 6 GHz band. This standard aims to boost data speed (throughput-per-area) in crowded places like offices and malls.
