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. Service provisioning to add and remove devices from the network.Bridging and routing between devices on the network.Physical support for wireless and wired networking.These devices normally combine three primary functions: 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.
