2. Long-range Wi-Fi - Wikipedia

   en.wikipedia.org/wiki/Long-range_Wi-Fi

   Long-range Wi-Fi especially in the 2.4 GHz band (as the shorter-range higher-bit-rate 5.8 GHz bands become popular alternatives to wired LAN connections) have proliferated with specialist devices. While Wi-Fi hotspots are ubiquitous in urban areas, some rural areas use more powerful longer-range transceivers as alternatives to cell ( GSM , CDMA ...

3. 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.

4. IEEE 802.11n-2009 - Wikipedia

   The Wi-Fi Alliance has also retroactively labelled the technology for the standard as Wi-Fi 4. [ 9 ] [ 10 ] It standardized support for multiple-input multiple-output (MIMO), frame aggregation , and security improvements, among other features, and can be used in the 2.4 GHz or 5 GHz frequency bands.

5. Cantenna - Wikipedia

   en.wikipedia.org/wiki/Cantenna

   The 5.5 GHz cantenna dimensions are almost perfect in that they make a good fit for the standard TV satellite dish. The resulting setup is a low-cost high-quality high-gain antenna. [6] Such setups are widely used in wireless community networks for long-distance Wi-Fi links. Cantennas may be used with other RF devices such as wireless security ...

6. Short backfire antenna - Wikipedia

   en.wikipedia.org/wiki/Short_backfire_antenna

   A short backfire antenna (or short back-fire, SBA, SBF or SBFA) is a type of a directional antenna, characterized by high gain, relatively small size, and narrow band. It has a shape of a disc with a straight edge, with a vertical pillar with a dipole acting as the driven element in roughly the middle and a conductive disc at the top acting as ...

7. Wi-Fi 7 - Wikipedia

   en.wikipedia.org/wiki/Wi-Fi_7

   IEEE 802.11be, dubbed Extremely High Throughput (EHT), is a wireless networking standard in the IEEE 802.11 set of protocols [9] [10] which is designated Wi-Fi 7 by the Wi-Fi Alliance. [ 11 ] [ 12 ] [ 13 ] It has built upon 802.11ax , focusing on WLAN indoor and outdoor operation with stationary and pedestrian speeds in the 2.4, 5, and 6 GHz ...
