  2. Point coordination function - Wikipedia

    en.wikipedia.org/wiki/Point_Coordination_Function

    Point Coordination Function (PCF) is a media access control (MAC) technique used in IEEE 802.11 based WLANs, including Wi-Fi. It resides in a point coordinator also known as access point (AP), to coordinate the communication within the network.

  3. IEEE 802.11e-2005 - Wikipedia

    en.wikipedia.org/wiki/IEEE_802.11e-2005

    The original 802.11 MAC defines another coordination function called the point coordination function (PCF). This is available only in "infrastructure" mode, where stations are connected to the network through an Access Point (AP). This mode is optional, and only very few APs or Wi-Fi adapters actually implement it.

  4. Inter-Access Point Protocol - Wikipedia

    en.wikipedia.org/wiki/Inter-Access_Point_Protocol

    Inter-Access Point Protocol or IEEE 802.11F is a recommendation that describes an optional extension to IEEE 802.11 that provides wireless access point communications among multivendor systems. [ 1 ] 802.11 is a set of IEEE standards that govern wireless networking transmission methods.

  5. Wireless access point - Wikipedia

    en.wikipedia.org/wiki/Wireless_access_point

    In computer networking, a wireless access point (WAP) (also just access point (AP)) is a networking hardware device that allows other Wi-Fi devices to connect to a wired network or wireless network. As a standalone device, the AP may have a wired or wireless connection to a switch or router , but in a wireless router it can also be an integral ...

  6. Distributed coordination function - Wikipedia

    en.wikipedia.org/wiki/Distributed_Coordination...

    The IEEE 802.11 standard also defines an optional access method using a point coordination function (PCF). PCF allows the access point acting as the network coordinator to manage channel access. The IEEE 802.11e amendment to the standard enhances the DCF and the PCF, through a new coordination function called Hybrid Coordination Function (HCF).

  7. Wireless distribution system - Wikipedia

    en.wikipedia.org/wiki/Wireless_distribution_system

    A wireless distribution system (WDS) is a system enabling the wireless interconnection of access points in an IEEE 802.11 network. It allows a wireless network to be expanded using multiple access points without the traditional requirement for a wired backbone to link them.

  8. IIf - Wikipedia

    en.wikipedia.org/wiki/IIf

    The syntax of the IIf function is as follows: IIf(expr, truepart, falsepart) All three parameters are required: e expr is the expression that is to be evaluated. truepart defines what the IIf function returns if the evaluation of expr returns true. falsepart defines what the IIf function returns if the evaluation of expr returns false.

  9. Wireless gateway - Wikipedia

    en.wikipedia.org/wiki/Wireless_gateway

    It may be implemented as software or hardware or a combination of both. Wireless gateways combine the functions of a wireless access point, a router, and often provide firewall functions as well. They provide network address translation (NAT) functionality, so multiple users can use the internet with a single public IP. [1]
