What Is WiFi Direct And Its Benefits | HP® Tech Takes

There are several options when it comes to wireless connectivity for printers. Of course, connecting over a WiFi network is the typical solution, but there are alternatives. One of these is WiFi Direct, a clever means of using standard WiFi technology to allow two devices to talk directly. WiFi Direct simply uses a device's built-in WiFi adapter to find and talk to other devices with a WiFi adapter. This type of communication is synonymous with walkie-talkie radios using their transmitters and receivers to connect directly. This scenario is different from regular WiFi connections that connect devices via an access point or router. This latter scenario is synonymous with mobile telephones that connect via radio masts, even if the phones are next to each other. WiFi Direct uses the standard WiFi Protected Setup (WPS) provisioning protocol to manage the authorization of connections. Security is a particular issue for PIN-based WPS; a person within the eavesdropping range of the communicating devices may easily guess short PINs. In some cases, devices may use a fixed default pin. WiFi Direct operates by capable devices sending discovery messages to scan for any other device within detection range that have WiFi Direct enabled.

Wi-Fi Direct - Wikipedia

Wi-Fi Direct is a Wi-Fi standard for wireless connections that allows two devices to establish a direct Wi-Fi connection without an intermediary wireless access point, router, or Internet connection. Wi-Fi Direct is single-hop communication, rather than multi-hop communication like wireless ad hoc networks. The Wi-Fi Direct standard was specified in 2009. It is useful for things such as file transfer, casting and projecting with Miracast, wireless printing, and to communicate with one or more devices simultaneously at typical Wi-Fi speeds (IEEE 802.11) without requiring a hotspot or an Internet connection. 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. Simultaneous connections also allow one device connected via an infrastructure local area network to the Internet to share the Internet connection to devices it is connected through Wi-Fi Direct. Wi-Fi Direct has become a standard feature in smart phones and portable media players, and in feature phones as well. 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.

To give the world the wireless technology standard it so desperately needed, the Wi-Fi Alliance, a non-profit organization that promotes Wi-Fi technology and certifies Wi-Fi products if they conform to certain standards of interoperability, developed the WiFi Direct standard, enabling devices to easily connect with each other without requiring a wireless router. WiFi Direct is built upon the same WiFi technology used by most modern consumer electronic devices to communicate with wireless routers. It allows two devices to communicate with each other, provided that at least one of them is compliant with the standard to establish a peer-to-peer connection. Before WiFi Direct, it was possible to establish a similar connection with ad-hoc networking, a decentralized type of wireless network that doesn’t rely on pre-existing infrastructure, but WiFi Direct makes decentralized wireless networking accessible even to people who are not technically inclined. Wi-Fi Protected Setup is a network security standard created by the Wi-Fi Alliance to allow home users who know little of wireless security and may be intimidated by the available security options to set up WPA, a protocol and security certification program developed by the Wi-Fi Alliance to secure wireless computer networks. WiFi Direct is supported by more devices than most people realize. Many hardware devices and peripherals, such as portable media players, wireless headsets, computer mice and keyboards, or printers, use WiFi direct to connect with other devices instead of Bluetooth. That’s great news for end users because WiFi Direct is straightforward to use as there are no unwieldy set-up procedures to go through.

What Is Wi-Fi Direct, and How Does It Work?

You may already have a device using Wi-Fi Direct. For example, the Roku 3 comes with a remote control that it communicates with using Wi-Fi Direct rather than using an older IR blaster or Bluetooth connection. The remote control doesn't actually connect to your wireless router. The Miracast wireless display standard also uses Wi-Fi Direct, although this doesn't engender much confidence, as Miracast seems so incompatible between different devices. Peripherals, such as mice and keyboards, could also communicate via Wi-Fi Direct. Many devices are already using Wi-Fi with built-in Wi-Fi radios. Rather than build in different hardware, such as Bluetooth, Wi-Fi Direct allows them to communicate wirelessly without requiring any additional specialized hardware. It adds additional functionality without requiring different hardware. Wi-Fi Direct uses a number of standards to accomplish its functions:

It was decided that in stereos “Hi-Fi” didn’t really imply anything and neither would “Wi-Fi”. But the point was that only spread spectrum radio products tested for interoperability would be allowed to put the Wi-Fi logo and brand name on their boxes and in their product literature. The WECA trade association then changed its name at this time to be the “Wi-Fi Alliance”. As everyone now knows, 802.11 spread spectrum radio networking known as “Wi-Fi” has since become a fairly ubiquitous technology all over the world, likely because of the Wi-Fi Alliance’s interoperability testing programs. The rest, as they say, is history. ... Most people using WiFi direct don’t know they are using it. Answer: Exactly what it says.

Don't have Wireless Access Point? No worries. You can use Wi-Fi Direct to provide device-to-device connectivity without wireless AP. Here is how. Don't have a wireless Access Point? No worries. You can use WiFi Direct to provide device-to-device connectivity without a wireless AP. The WiFi Direct feature lets two devices establish a direct, peer-to-peer WiFi connection without requiring a wireless router. Think of it like a better version of Bluetooth — accessible, easy to use, and provides new unique functions to your devices. WiFi Direct is similar in concept to the "ad-hoc" WiFi mode. Users can either use a push button or a PIN code to establish secure connections. While WiFi Direct is different from Bluetooth, the two share some resemblance to one another. Just like with Bluetooth connections, you can seamlessly transfer files between devices, and share one device's screen onto the other device. Services such as Miracast, which allow users to cast Android device screens to TV screens, use this technology already. However, you can explore even more possibilities than Miracast if you utilize WiFi Direct on Windows 10. WiFi Direct is supported on Windows 10 IoT Core devices through the use of a WiFi Direct enabled USB WiFi adapter.
