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 channels numbered at 5 MHz spacing (except in the 45/60 GHz band, where they are 0.54/1.08/2.16 GHz apart) between the centre frequency of the channel.
In the USA, CFR Title 47 Part 15 (revised in 2005) describes the regulation of the U-NII bands. The FCC's U-NII regulations for 5 GHz wireless operation in the USA. RadioElectronics' article on Wi-Fi / WLAN Channels, Frequencies, Bands & Bandwidths; Air802's article with tables of data on FCC Rules and Regulations which specifies frequencies ...
Wireless network devices use wavebands as follows: IEEE 802.11/Wi-Fi 2450 MHz and 5800 MHz bands; Bluetooth 2450 MHz band [10] falls under WPAN; ANT / ANT+ (originates from Adaptive Network Topology) is a proprietary (but open access) multicast wireless sensor network technology designed and marketed by ANT Wireless. ANT devices may use any RF ...
IEEE 802.11ac-2013 or 802.11ac is a wireless networking standard in the IEEE 802.11 set of protocols (which is part of the Wi-Fi networking family), providing high-throughput wireless local area networks (WLANs) on the 5 GHz band. [e] The standard has been retroactively labelled as Wi-Fi 5 by Wi-Fi Alliance. [9] [10]
Dynamic Frequency Selection (DFS) is a channel allocation scheme specified for wireless LANs, commonly known as Wi-Fi. It is designed to prevent electromagnetic interference by avoiding co-channel operation with systems that predated Wi-Fi, such as military radar , satellite communication , and weather radar , and also to provide on aggregate a ...
Citizens Broadband Radio Service (CBRS) is a 150 MHz wide broadcast band of the 3.5 GHz band (3550 MHz to 3700 MHz) in the United States. [1] In 2017, the US Federal Communications Commission (FCC) completed a process which began in 2012 to establish rules for commercial use of this band, while reserving parts of the band for the US Federal Government to limit interference with US Navy radar ...
802.11b ist outdated since long, simply use the same modulation-modes as on 5GHz and also the same channel-spacing. That means you can use wifi-channel 1,5,9,13 (keep in mind that in the USA channel 13 has some limitations). Keep it clean for the User, do NOT name the 40MHZ-Channels by mid-frequency, name them by 20MHz fallback-channel.
A very large use is by the high frequency (5.2 GHz) band of Wi-Fi (IEEE 802.11a) wireless computer networks. These are the most widely used computer networks in the world, used to allow laptops , smartphones , printers and TVs to connect to the internet through a wireless router in home and small office networks, and access points in hotels ...
