Tunneled Direct Link Setup
TDLS, shortened from Tunneled Direct Link Setup, is "a seamless way to stream media and other data faster between devices already on the same Wi-Fi network." Devices using it communicate directly with one another, without involving the wireless network's router. Wi-Fi Alliance added certification for TDLS in 2012. It describes this feature as technology that enables devices to link directly to one another when connected to a traditional Wi-Fi network. Wi-Fi CERTIFIED TDLS devices can set up secure links and transfer data directly between them. TDLS-linked devices benefit from an optimized connection to do things such as streaming video or synching content, without burdening the network as a whole. The IEEE has endorsed this as the IEEE 802.11z standard. Google's Cast protocol used by Chromecast utilizes TDLS to initiate screen mirroring.

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] |
Wi-Fi
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 ...

Google Cast
Google Cast is a proprietary protocol developed by Google for playing locally stored or Internet-streamed audiovisual content on a compatible consumer device. The protocol is used to initiate and control playback of content on digital media players, high-definition televisions, and home audio systems using a mobile device, personal computer, or smart speaker. The protocol was first launched on July 24, 2013, to support Google's first-generation Chromecast player. The Google Cast SDK was released on February 3, 2014, allowing third parties to modify their software to support the protocol. According to Google, over 20,000 Google Cast-ready apps were available as of May 2015. Support for Google Cast has since been integrated into subsequent devices, such as the Nexus Player and other Android TV devices (such as televisions), as well as soundbars, speakers, and later models of the Chromecast. Consumer devices that natively support the protocol were marketed as Chromecast built-in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...
