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.
This Linksys WRT54GS, a combined router and Wi‑Fi access point, operates using the 802.11g standard in the 2.4 GHz ISM band using signalling rates up to 54 Mbit/s. For comparison, this Netgear product, a combined router and Wi‑Fi access point from 2013, uses the 802.11ac standard in the 5 GHz band, with signalling rates up to 6933 Mbit/s.
Many of the cordless telephones and baby monitors in the United States and Canada use the 2.4 GHz frequency, [ 1] the same frequency at which Wi-Fi standards 802.11b, 802.11g, 802.11n and 802.11ax operate. This can cause a significant decrease in speed, or sometimes the total blocking of the Wi-Fi signal when a conversation on the phone takes ...
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, 6 GHz and 60 GHz bands. [92] [93] [94] 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 ...
Wireless ad hoc network. A wireless ad hoc network [1] ( WANET) or mobile ad hoc network ( MANET) is a decentralized type of wireless network. The network is ad hoc because it does not rely on a pre-existing infrastructure, such as routers or wireless access points. Instead, each node participates in routing by forwarding data for other nodes.
The Alice Network. The Alice Network is a 2017 historical novel by American author Kate Quinn. It was a New York Times and USA Today bestseller. The story is based on the real-life World War I spy ring called the Alice Network, which operated in German-occupied France and Belgium. Three historical figures are used as characters in the novel:
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, [ 9] with an extended version, Wi-Fi 6E, that adds the 6 GHz band. [ 10] It is an upgrade from Wi-Fi 5 ( 802.11ac ), with improvements for better performance in crowded places.
Long-range Wi-Fi. Long-range Wi-Fi is used for low-cost, unregulated point-to-point computer network connections, as an alternative to other fixed wireless, cellular networks or satellite Internet access . Wi-Fi networks have a range that's limited by the frequency, transmission power, antenna type, the location they're used in, and the ...
