  2. IEEE 802.11n-2009 - Wikipedia

    en.wikipedia.org/wiki/IEEE_802.11n-2009

    An 802.11n-only network may be impractical for many users because they need to support legacy equipment that still is 802.11b/g only. In a mixed-mode system, an optimal solution would be to use a dual-radio access point and place the 802.11b/g traffic on the 2.4 GHz radio and the 802.11n traffic on the 5 GHz radio. [20]

  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. Wireless repeater - Wikipedia

    en.wikipedia.org/wiki/Wireless_repeater

    There are wireless range extending devices that conform to all 802.11 protocols. Most 802.11 compliant devices are backward compatible. However, 802.11ac runs at 5 GHz and requires an access point capable of 5 GHz operation. 802.11ac equipment is backward compatible with 802.11n, 802.11g, or 802.11b equipment.

  5. Wi-Fi - Wikipedia

    en.wikipedia.org/wiki/Wi-Fi

    Wi-Fi (/ ˈ w aɪ f aɪ /) [1] [a] is a family of wireless network protocols based on the IEEE 802.11 family of standards, which are commonly used for local area networking of devices and Internet access, allowing nearby digital devices to exchange data by radio waves.

  6. Long-range Wi-Fi - Wikipedia

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

    But in long-range Wi-Fi, special technologies are used to get the most out of a Wi-Fi connection. The 802.11-2007 standard adds 10 MHz and 5 MHz OFDM modes to the 802.11a standard, and extend the time of cyclic prefix protection from 0.8 μs to 3.2 μs, quadrupling the multipath distortion protection. Some commonly available 802.11a/g chipsets ...

  7. Wireless gateway - Wikipedia

    en.wikipedia.org/wiki/Wireless_gateway

    It has a wired connection to the ISP, at least one jack port for the LAN (usually four jacks), and an antenna for wireless users. The wireless gateway could support wireless 802.11b and 802.11g with speed up to 56 Mbit/s, 802.11n with speed up to 300Mps and recently the 802.11ac with speed up to 1200 Mbit/s. [3]

    en.wikipedia.org/wiki/Wireless_LAN

    This notebook computer is connected to a wireless access point using a PC Card wireless card. An example of a Wi-Fi network. A wireless LAN (WLAN) is a wireless computer network that links two or more devices using wireless communication to form a local area network (LAN) within a limited area such as a home, school, computer laboratory, campus, or office building.
