To address those roles, a number of different protocols have developed, including Universal Plug and Play (UPnP), Devices Profile for Web Services (DPWS), and zero-configuration networking (ZeroConf). It provides little help within a network - finding and setting up printer access from a computer for instance. While the Protected Setup model works as intended, it was intended only to simplify the connection between the access point and the devices that would make use of its services, primarily accessing the Internet. From the user's point of view, a single click replaces the multi-step, jargon-filled setup experience formerly required. The Protected Setup system uses this information to send data to a computer, handing it the information needed to complete the network setup and connect to the Internet. Wi-Fi Protected Setup allows access points to be set up simply by entering a PIN or other identification into a connection screen, or in some cases, simply by pressing a button. To address these problems, there have been numerous attempts to simplify certain aspects of the setup task.Ī common example is the Wi-Fi Protected Setup system included in most access points built since 2007 when the standard was introduced.
At the same time, the increasing sophistication of the hot spots presented setup problems for the users. With the increase in the number and type of devices attaching to Wi-Fi systems, the basic model of a simple router with smart computers became increasingly strained. The Wi-Fi Direct devices negotiate when they first connect to determine which device shall act as an access point. In contrast, Wi-Fi Direct devices are able to communicate with each other without requiring a dedicated wireless access point. All communication between devices goes through the access point. Most Wi-Fi networks are set up in infrastructure mode, where the access point acts as a central hub to which Wi-Fi capable devices are connected. Ī typical Wi-Fi home network includes laptops, tablets and phones, devices like modern printers, music devices, and televisions.

The "pairing" of Wi-Fi Direct devices can be set up to require the proximity of a near field communication, a Bluetooth signal, or a button press on one or all the devices.Ĭonventional Wi-Fi networks are typically based on the presence of controller devices known as wireless access points. Wi-Fi Direct negotiates the link with a Wi-Fi Protected Setup system that assigns each device a limited wireless access point. Only one of the Wi-Fi devices needs to be compliant with Wi-Fi Direct to establish a peer-to-peer connection that transfers data directly between them with greatly reduced setup. One advantage of Wi-Fi Direct is the ability to connect devices even if they are from different manufacturers. It is useful for everything from internet browsing to file transfer, and to communicate with one or more devices simultaneously at typical Wi-Fi speeds. Wi-Fi becomes a way of communicating wirelessly, much like Bluetooth. Wi-Fi Direct is single-hop communication, rather than multihop communication like wireless ad hoc networks. Wi-Fi Direct (formerly Wi-Fi Peer-to-Peer) is a Wi-Fi standard for peer-to-peer wireless connections that allows two devices to establish a direct Wi-Fi connection without an intermediary wireless access point, router, or Internet connection.
