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.
Wi-Fi 6, or IEEE 802.11ax, is an IEEE standard from the Wi-Fi Alliance, for wireless networks ( WLANs ). It operates in the 2.4 GHz and 5 GHz bands, [8] with an extended version, Wi-Fi 6E, that adds the 6 GHz band. [9] It is an upgrade from Wi-Fi 5 ( 802.11ac ), with improvements for better performance in crowded places.
Information and communications technology ( ICT) is an extensional term for information technology (IT) that stresses the role of unified communications [1] and the integration of telecommunications ( telephone lines and wireless signals) and computers, as well as necessary enterprise software, middleware, storage and audiovisual, that enable ...
RF and microwave filter. Radio frequency (RF) and microwave filters represent a class of electronic filter, designed to operate on signals in the megahertz to gigahertz frequency ranges ( medium frequency to extremely high frequency ). This frequency range is the range used by most broadcast radio, television, wireless communication (cellphones ...
Ethernet. Ethernet ( / ˈiːθərnɛt / EE-thər-net) is a family of wired computer networking technologies commonly used in local area networks (LAN), metropolitan area networks (MAN) and wide area networks (WAN). [1] It was commercially introduced in 1980 and first standardized in 1983 as IEEE 802.3.
Bluetooth is a short-range wireless technology standard that is used for exchanging data between fixed and mobile devices over short distances and building personal area networks (PANs). In the most widely used mode, transmission power is limited to 2.5 milliwatts, giving it a very short range of up to 10 metres (33 ft).
See media help. The International Radiotelephony Spelling Alphabet or simply Radiotelephony Spelling Alphabet, commonly known as the NATO phonetic alphabet, is the most widely used set of clear-code words for communicating the letters of the Roman alphabet. Technically a radiotelephonic spelling alphabet, it goes by various names, including ...
