![]() Samsung S4 License Agreement AndPhysical 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.Conventional 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. The Wi-Fi Direct devices negotiate when they first connect to determine which device shall act as an access point.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 devices do not communicate directly with each other (that is, unlike in " ad-hoc mode"), but they go through the access point.In contrast, Wi-Fi Direct devices are able to communicate with each other without requiring a dedicated wireless access point. The majority of 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. Service provisioning to add and remove devices from the network.A typical Wi-Fi home network includes laptops, tablets and phones, devices like modern printers, music devices, and televisions. It provides little help within a network - finding and setting up printer access from a computer for instance. From the user's point of view, a single click replaces the multi-step, jargon-filled setup experience formerly required.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. 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.A common example is the Wi-Fi Protected Setup system included in most access points built since 2007 when the standard was introduced. A guest using their smart phone would likely be able to find a hotspot and connect to the Internet with ease, perhaps using Protected Setup to do so. Although systems like UPnP and Bonjour provide many of the needed capabilities and are included in some devices, a single widely supported standard was lacking, and support within existing devices was far from universal. Although the ad hoc mode was created to address this sort of need, the lack of additional information for discovery makes it difficult to use in practice. Even without a central Wi-Fi hub or router, it would be useful for a laptop computer to be able to wirelessly connect to a local printer. The process of adding Wi-Fi to smaller devices has accelerated, and it is now possible to find printers, cameras, scanners, and many other common devices with Wi-Fi in addition to other connections, like USB.The widespread adoption of Wi-Fi in new classes of smaller devices made the need for ad hoc networking much more important. These protocols allow devices to seek out other devices within the network, query their capabilities, and provide some level of automatic setup.Wi-Fi Direct has become a standard feature in smart phones and portable media players, and in feature phones as well. Android version 4.2 (Jellybean) included further refinements to Wi-Fi Direct including persistent permissions enabling two-way transfer of data between multiple devices.The Miracast standard for the wireless connection of devices to displays is based on Wi-Fi direct.Wi-Fi Direct essentially embeds a software access point (" Soft AP"), into any device that must support Direct. This has begun with Wi-Fi mouse products, and Wi-Fi Direct remote controls that were shipping circa November 2012.File sharing applications such as SHAREit on Android and BlackBerry 10 devices could use Wi-Fi Direct, with most Android version 4.1 (Jellybean), introduced in July 2012, and BlackBerry 10.2 supported. Wireless mice, keyboards, remote controls, headsets, speakers, displays, and many other functions can be implemented with Wi-Fi Direct. ![]() Wi-Fi Direct devices can connect to a notebook computer that plays the role of a software Access Point (AP). Commercialization Laptops Intel included Wi-Fi Direct on the Centrino 2 platform, in its My WiFi technology by 2008. The specification is available for purchase from the Wi-Fi Alliance. Free excel templates for macWi-Fi Direct became available with the Blackberry 10.2 upgrade. Ozmo Devices, which developed integrated circuits (chips) designed for Wi-Fi Direct, was acquired by Atmel in 2012. While some Android 2.3 devices like Samsung Galaxy S II have had this feature through proprietary operating system extensions developed by OEMs, the Galaxy Nexus (released November 2011) was the first Android device to ship with Google's implementation of this feature and an API for developers. Mobile devices An icon to indicate Wi-Fi Direct operation under Android.Google announced Wi-Fi Direct support in Android 4.0 in October 2011. Redpine Signals's chipset was Wi-Fi Direct certified in November of the same year. Marvell Technology Group, Atheros, Broadcom, Intel, Ralink, and Realtek announced their first products in October 2010. NVIDIA claims a reduction in latency and increase in throughput over competing Bluetooth controllers. NVIDIA's SHIELD controller uses Wi-Fi Direct to connect to compatible devices. This protocol and others are used in the feature AirDrop, used to transfer large files between Apple devices using a similar (but proprietary) technology to Wi-Fi Direct.The Xbox One, released in 2013, supports Wi-Fi Direct.
