Wi-Fi Wi-Fi certification

1 This includes wireless local area network (WLAN) connections, device to device connectivity (such as Wi-Fi

Peer to Peer aka Wi-Fi Direct), Personal area network (PAN), local area network (LAN) and even some limited wide area network (WAN)

connections


Wi-Fi Direct computer-to-computer communications

1 Similarly, the Wi-Fi Alliance promotes a specification called Wi-Fi Direct for

file transfers and media sharing through a new discovery- and

security-methodology. Wi-Fi Direct launched in October 2010.


Wireless LAN - Peer-to-peer

1 An Wireless Ad Hoc network|ad hoc network (not the same as a Wi-Fi

Direct|WiFi Direct network http://www.wi-fi.org/knowledge-

center/faq/same-ad-hoc-mode) is a network where stations communicate only peer to peer (P2P). There is no

base and no one gives permission to talk.



1 A Wi-Fi Direct|WiFi Direct network is another type of network where

stations communicate peer to peer (P2P).



1 There are two main methods to establish a group owner in the Wi-Fi Direct group


Wi-Fi Direct

1 Wi-Fi Direct may not only replace the need for routers, but may also

replace the need of Bluetooth for applications that do not rely on

Bluetooth low energy|low energy.


Wi-Fi Direct - Basic Wi-Fi

1 The Wi-Fi Direct devices negotiate when they first connect to determine which device shall act as an access

point.


Wi-Fi Direct - New uses

1 Wi-Fi Direct can provide a wireless connection to peripherals. Wireless mice,

keyboards, remote controls, headsets, speakers, displays and many other

functions can be implemented with Wi-Fi Direct. This has begun with Wi-Fi mouse products, wireless display products such as Wireless display|WiDi and Miracast as well as Wi-Fi Direct remote controls that

were shipping circa November 2012.


Wi-Fi Direct - New uses

1 File sharing applications on Android and BlackBerry 10 devices could use

Wi-Fi Direct, with most Android Version 4.1 (Jellybean) and

BlackBerry 10.2 supported. Android version 4.2 (Jellybean) included

further refinements to Wi-Fi Direct including persistent permissions

enabling two-way transfer of data between multiple devices.


Wi-Fi Direct - Technical description

1 Wi-Fi Direct essentially embeds a software access point (SoftAP|Soft

AP), into any device that must support Direct. The soft AP provides a version of Wi-Fi Protected Setup with its push-button or PIN-based

setup.



1 When a device enters the range of the Wi-Fi Direct host, it can connect

to it, and then gather setup information using a Protected Setup-style transfer. Connection and setup is so simplified that some suggest it

may replace Bluetooth in some situations.Chris Foresman, , Ars

Technica, 14 October 2009



1 Wi-Fi Direct-certified devices can connect one-to-one or one-to-many and not all connected products need to be Wi-Fi Direct-certified. One Wi-Fi Direct enabled device can connect to

legacy Wi-Fi certified devices.



1 The Wi-Fi Direct certification program is developed and administered by the Wi-Fi Alliance, the industry group that

owns the Wi-Fi trademark. The specification is available for purchase

from the Wi-Fi Alliance.


Wi-Fi Direct - Commercialization

1 Google announced Wi-fi Direct support in Android (Operating

System)|Android 4.0 in October of the following year



1 Ozmo Devices, which developed integrated circuits (chips) designed

for Wi-Fi Direct, was acquired by Atmel in 2012.



1 The Xbox one|Xbox One, set to be released in 2013, will support Wi-Fi direct.


WiFi - Wi-Fi certification

1 This includes wireless LAN|wireless local area network (WLAN)

connections, device to device connectivity (such as Wi-Fi Peer to

Peer aka Wi-Fi Direct), Personal area network (PAN), local area network (LAN) and even some limited wide area network (WAN) connections


Xbox One - Hardware

1 For networking, Xbox One supports Gigabit Ethernet, 802.11n wireless, and Wi-Fi Direct.


Roku - Third generation

1 On March 5, 2013, Roku announced the release of their updated media player, Roku 3, with a

CPU that's five times faster than the Roku 2 XS, and a Wi-Fi Direct remote in place of Bluetooth. The Roku 3 remote includes a headphone jack

(with headphones provided) for a private listening

mode.[http://www.latimes.com/business/technology/la-fi-tn-roku-3-available-for-purchase-online-20130305,0,2733700.story Roku 3, a faster and

Samsung Galaxy Express 2 - Hardware and design

1 Built into the battery is near field communication connectivity, which allows users to share map directions and YouTube videos quickly using Wi-

Fi Direct (through Android Beam), and perform Contactless payment|non-touch payments at shops that

employ specially equipped NFC cash registers


Samsung Galaxy S II Plus - Hardware and design

1 BCM4330 supports Wi-Fi Direct that communicate directly with one another

without having to interact with an access point.[

Wi-Fi Alliance - Wi-Fi Direct

1 In October 2010, the Alliance began to certify Wi-Fi Direct, that allows Wi-Fi-enabled devices to communicate

directly with each other, without going through a wireless access point

or hotspot.


Wi-Fi Alliance - Wi-Fi Direct

1 Since 2009 when it was first announced, some suggested Wi-Fi Direct might replace the need for

Bluetooth on applications that do not rely on Bluetooth low energy.


Atmel - Acquisitions

1 Ozmo Devices, which developed products for Wi-Fi Direct, was acquired by Atmel in

December 2012.


Miracast

1 'Miracast' is a peer-to-peer wireless screencasting standard formed via

Wi-Fi Direct connections in a manner similar to Bluetooth


Miracast - Devices

1 In October 2013, BlackBerry released it's 10.2 update to the existing line of BlackBerry 10 devices, which brings Miracast and Wi-Fi Direct support to

the Z30, Q10 and Q5 models.


Miracast - Disadvantages

1 Its reliance on Wi-Fi Direct also reduces the attractiveness of the

technology in enterprise environment.


Miracast - Legacy device incompatibility

1 The Wi-Fi Alliance certified the Wi-Fi Direct protocol in October 2010, and the first

smartphone to ship with Wi-Fi Direct was the Samsung Galaxy S II, released in

February 2011. All new Android devices starting with Android 4.0x (Ice Cream

Sandwich) support Wi-Fi Direct. Desktop PC hardware can be upgraded with new Wi-Fi-

Direct-compatible hardware. Only embedded devices will not be able to be

upgraded.https://store.theartofservice.com/the-wi-fi-direct-toolkit.html

Miracast - OS support

1 Miracast is also built into BlackBerry 10.2 devices and Microsoft Windows

8.1 although developers can implement Miracast on top of the

built-in Wi-Fi Direct support in Windows 7 and Windows 8


Features new to Windows 8 - Printing

Android Beam - S Beam

1 'S Beam' refers to an extension of Android Beam by Samsung, first used on their Samsung

Galaxy S III|Galaxy S III phones. It uses the near-field communication to establish a Wi-Fi Direct connection between two devices for the data transfer.Samsung's S Beam teaches Android a

new trick. CNet. June 20, 2012. http://reviews.cnet.com/8301-19736_7-

57455744-251/samsungs-s-beam-teaches-android-a-new-trick/ Accessed Jan 13, 2013 This

results in faster transfer speeds between devices which feature S Beam.


Android Beam - S Beam vs. Android Beam

1 Unlike Android Beam, S Beam uses Wi-Fi Direct instead of Bluetooth,

resulting in a quicker transfer time. S Beam is also limited to devices with S Beam support, Wi-Fi Direct, and Near field communication|NFC like HTC One and Samsung Galaxy S3.


WiFi Direct

1 Wi-Fi Direct may not only replace the need for Router (computing)|routers,

but may also replace the need of Bluetooth for applications that do not

rely on Bluetooth low energy|low energy.


WiFi Direct - New uses

1 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.Eric Griffith, [http://www.pcmag.com/article2/0,2817,235420
