Wi-Fi Direct
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 (computing), router, or Internet connection. Wi-Fi Direct is single-hop communication, rather than Multi-hop routing, multi-hop communication like Wireless ad hoc network, 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. It is therefore similar to Bluetooth technology but offers a longer range. Only one of the Wi-Fi devices needs to be compliant with Wi-Fi Direct to establish a peer-to-peer connection. 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 And Wi-Fi Diect
Wi-Fi () is a family of wireless network protocols based on the IEEE 802.11 family of standards, which are commonly used for Wireless LAN, local area networking of devices and Internet access, allowing nearby digital devices to exchange data by radio waves. These are the most widely used computer networks, used globally in small office/home office, home and small office networks to link devices and to provide Internet access with wireless routers and wireless access points in public places such as coffee shops, restaurants, hotels, libraries, and airports. ''Wi-Fi'' is a trademark of the Wi-Fi Alliance, which restricts the use of the term "''Wi-Fi Certified''" to products that successfully complete Interoperability Solutions for European Public Administrations, interoperability certification testing. Non-compliant hardware is simply referred to as WLAN, and it may or may not work with "''Wi-Fi Certified''" devices. the Wi-Fi Alliance consisted of more than 800 companies from ar ...

Wi-Fi Alliance
The Wi-Fi Alliance is a non-profit organization that owns the Wi-Fi trademark. Manufacturers may use the trademark to brand products certified for Wi-Fi interoperability. It is based in Austin, Texas. History Early IEEE 802.11, 802.11 products suffered from interoperability problems because the Institute of Electrical and Electronics Engineers (IEEE) had no provision for testing equipment for compliance with its standards. In 1999, pioneers of a new, higher-speed variant endorsed the IEEE 802.11b specification to form the Wireless Ethernet Compatibility Alliance (WECA) and branded the new technology Wi-Fi. The group of companies included 3Com, Aironet (acquired by Cisco), Harris Semiconductor (now Intersil), Lucent Technologies (the WLAN part was renamed as Orinoco, become part of Avaya, then acquired by Extreme Networks), Nokia and Symbol Technologies (acquired by Motorola, Zebra Technologies, and now Extreme Networks). The alliance lists Apple Inc., Apple, Comcast, Samsung ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
WPA2
Wi-Fi Protected Access (WPA) (Wireless Protected Access), Wi-Fi Protected Access 2 (WPA2), and Wi-Fi Protected Access 3 (WPA3) are the three security certification programs developed after 2000 by the Wi-Fi Alliance to secure wireless computer networks. The Alliance defined these in response to serious weaknesses researchers had found in the previous system, Wired Equivalent Privacy (WEP). WPA (sometimes referred to as the TKIP standard) became available in 2003. The Wi-Fi Alliance intended it as an intermediate measure in anticipation of the availability of the more secure and complex WPA2, which became available in 2004 and is a common shorthand for the full IEEE 802.11i (or IEEE 802.11i-2004) standard. In January 2018, the Wi-Fi Alliance announced the release of WPA3, which has several security improvements over WPA2. As of 2023, most computers that connect to a wireless network have support for using WPA, WPA2, or WPA3. All versions thereof, at least as implemented throu ...

Tethering
Tethering or phone-as-modem (PAM) is the sharing of a mobile device's cellular data connection with other connected computers. It effectively turns the transmitting device into a modem to allow others to use its cellular network as a gateway for Internet access. The sharing can be done wirelessly over wireless LAN (Wi-Fi), Bluetooth, IrDA or by physical connection using a cable like USB. If tethering is done over Wi-Fi, the feature may be branded as a personal hotspot or mobile hotspot, and the transmitting mobile device would also act as a portable wireless access point (AP) which may also be protected using a password. Tethering over Bluetooth may use the Personal Area Networking (PAN) profile between paired devices, or alternatively the Dial-Up Networking (DUN) profile where the receiving device virtually dials the cellular network APN, typically using the number ''*99''#. Mobile devices' OS support Many mobile devices are equipped with software to offer tethered Internet ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Digital Picture Frame
A digital photo frame (also called a digital media frame) is a picture frame that displays digital photos without the need of a computer or printer. The introduction of digital photo frames predates tablet computers, which can serve the same purpose in some situations; however, digital photo frames are generally designed specifically for the stationary, aesthetic display of photographs and therefore usually provide a nicer-looking frame and a power system designed for continuous use. Digital photo frames come in a variety of different shapes and sizes with a range of features. Some may even play videos as well as display photographs. Owners can choose a digital photo frame that utilizes a WiFi connection or not, comes with cloud storage, and/or USB and SD card hub. History The first generation of digital photo frames were introduced in the 1990s and included screens with the ability to accept memory cards directly from digital cameras. Widespread adoption of digital cameras ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SoftAP
SoftAP is an abbreviated term for "software enabled access point". Such access points utilize software to enable a computer which hasn't been specifically made to be a router into a wireless access point. It is often used interchangeably with the term "virtual router". History on Windows The first SoftAP software was shipped by Ralink with their Wi-Fi cards for Windows XP. It enabled a Wi-Fi card to act as a wireless access point. While a card was acting as a wireless access point, it could not continue to stay connected as a client, so any Internet access had to come from another device, such as an Ethernet device. Following Ralink's card innovation, a number of other Wi-Fi vendors, including Edimax, later released SoftAP software for their devices. Neither Ralink nor Edimax updated their software to work with Windows Vista, due to the installation of its new driver model, bringing an effective end to this software category until the release of Windows 7 in 2009.
