    en.wikipedia.org/wiki/WiFi_Sensing

    [2] [3] Wi-Fi Sensing allows for the utilization of conventional Wi-Fi transceiver hardware and Radio Frequency (RF) spectrum for both communication and sensing purposes. The integration of communication and sensing functionalities within mobile networking technology constitutes a large area of exploration and is commonly referred to as Joint ...

    en.wikipedia.org/wiki/2.4_GHz_radio_use

    Bluetooth devices intended for use in short-range personal area networks operate from 2.4 to 2.4835 GHz. To reduce interference with other protocols that use the 2.45 GHz band, the Bluetooth protocol divides the band into 80 channels (numbered from 0 to 79, each 1 MHz wide) and changes channels up to 1600 times per second.

    Radio and spread spectrum technologies – Wireless local area networks use a high-frequency radio technology similar to digital cellular and a low-frequency radio technology. Wireless LANs use spread spectrum technology to enable communication between multiple devices in a limited area. IEEE 802.11 defines a common flavor of open-standards ...

  6. Wireless mesh network - Wikipedia

    en.wikipedia.org/wiki/Wireless_mesh_network

    Wireless mesh architecture is a first step towards providing cost effective and low mobility over a specific coverage area. Wireless mesh infrastructure is, in effect, a network of routers minus the cabling between nodes. It is built of peer radio devices that do not have to be cabled to a wired port like traditional WLAN access points (AP) do ...

  7. List of WLAN channels - Wikipedia

    en.wikipedia.org/wiki/List_of_WLAN_channels

    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.
