Wi-Fi is a family of wireless network protocols based on the IEEE 802.11 family of standards, which are commonly used for 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 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, hotels, libraries, and airports to provide visitors.
Augmented reality (AR) is an interactive experience that combines the real world and computer-generated content. The content can span multiple sensory modalities, including visual, auditory, haptic, somatosensory and olfactory. AR can be defined as a system that incorporates three basic features: a combination of real and virtual worlds, real-time interaction, and accurate 3D registration of virtual and real objects. The overlaid sensory information can be constructive, or destructive. As such, it is one of the key technologies in the reality-virtuality continuum.
In computer networking, a wireless access point, or more generally just access point (AP), is a networking hardware device that allows other Wi-Fi devices to connect to a wired network or wireless network. As a standalone device, the AP may have a wired connection to a switch or router, but, in a wireless router, it can also be an integral component of the router itself. An AP is differentiated from a hotspot, which is a physical location where Wi-Fi access is available.
Worldwide Interoperability for Microwave Access (WiMAX) is a family of wireless broadband communication standards based on the IEEE 802.16 set of standards, which provide physical layer (PHY) and media access control (MAC) options.
A timeline of United States inventions encompasses the ingenuity and innovative advancements of the United States within a historical context, dating from the Contemporary era to the present day, which have been achieved by inventors who are either native-born or naturalized citizens of the United States. Patent protection secures a person's right to his or her first-to-invent claim of the original invention in question, highlighted in Article I, Section 8, Clause 8 of the United States Constitution which gives the following enumerated power to the United States Congress:
To promote the Progress of Science and useful Arts, by securing for limited Times to Authors and Inventors the exclusive Right to their respective Writings and Discoveries.
WirelessHD, also known as UltraGig, is a proprietary standard owned by Silicon Image for wireless transmission of high-definition video content for consumer electronics products. The consortium currently has over 40 adopters; key members behind the specification include Broadcom, Intel, LG, Panasonic, NEC, Samsung, SiBEAM, Sony, Philips and Toshiba. The founders intend the technology to be used for Consumer Electronic devices, PCs, and portable devices.
Piggybacking on Internet access is the practice of establishing a wireless Internet connection by using another subscriber's wireless Internet access service without the subscriber's explicit permission or knowledge. It is a legally and ethically controversial practice, with laws that vary by jurisdiction around the world. While completely outlawed or regulated in some places, it is permitted in others.
Microsoft PixelSense was an interactive surface computing platform that allowed one or more people to use and touch real-world objects, and share digital content at the same time. The PixelSense platform consists of software and hardware products that combine vision based multitouch PC hardware, 360-degree multiuser application design, and Windows software to create a natural user interface (NUI).
The OLPC XO is a low cost laptop computer intended to be distributed to children in developing countries around the world, to provide them with access to knowledge, and opportunities to "explore, experiment and express themselves". The XO was developed by Nicholas Negroponte, a co-founder of MIT's Media Lab, and designed by Yves Behar's Fuseproject company. The laptop is manufactured by Quanta Computer and developed by One Laptop per Child (OLPC), a non-profit 501(c)(3) organization.
In telecommunications, white spaces refer to radio frequencies allocated to a broadcasting service but not used locally. National and international bodies assign frequencies for specific uses and, in most cases, license the rights to broadcast over these frequencies. This frequency allocation process creates a bandplan which for technical reasons assigns white space between used radio bands or channels to avoid interference. In this case, while the frequencies are unused, they have been specifically assigned for a purpose, such as a guard band. Most commonly however, these white spaces exist naturally between used channels, since assigning nearby transmissions to immediately adjacent channels will cause destructive interference to both.
Wi-Fi positioning system is a geolocation system that uses the characteristics of nearby Wi‑Fi access point to discover where a device is located.
The Nokia 6301 is a triband GSM mobile phone approved by the FCC for the US market in January 2008. It has two major models; the 6301b RM-323 for the North American market and the 6301 RM-322 for the European market. Model 6301b is equipped with 850/1800/1900 MHz bands and model 6301 is equipped with 900/1800/1900 MHz bands.
The Motorola Xoom is an Android-based tablet computer by Motorola, introduced at CES 2011 on January 5, 2011. It was the first tablet to be sold with Android 3.0 Honeycomb. The Verizon branded Xoom was the first tablet to run Android 3.1. The Motorola Xoom went through the FCC on February 10, 2011 only 14 days before release. The 3G version was released on February 24, 2011, and the Wi-Fi version was released March 27, 2011. It was announced concurrently with three other products: the Motorola Atrix, the Motorola Droid Bionic, and the Motorola Cliq 2. CNET named it the "Best of the CES" 2011.
The Motorola Droid Bionic is an Android-based, 4G LTE-capable smartphone designed by Motorola. It was originally scheduled for release in Q2 2011 but was delayed, eventually being released on 8 September 2011.
IEEE 802.11ac-2013 or 802.11ac is a wireless networking standard in the IEEE 802.11 set of protocols, providing high-throughput wireless local area networks (WLANs) on the 5 GHz band. The standard has been retroactively labelled as Wi-Fi 5 by Wi-Fi Alliance.
Miracast is a wireless communications standard created by the Wi-Fi Alliance which is designed to transmit video and sound directly from devices to display receivers. It can roughly be described as "HDMI over Wi-Fi", replacing cables in favor of wireless. The protocol is utilised in many devices and is used or branded under various names by different manufacturers, including Smart View and AllShare Cast, SmartShare, screen mirroring, Cast, wireless display and screen casting.
Google Contact Lens was a smart contact lens project announced by Google on 16 January 2014.

The project was being carried out by Verily and as of 2014 was being tested using prototypes. On November 16, 2018, Verily announced it had discontinued the project.
Smartglasses or smart glasses are eye or head-worn wearable computers that offer useful capabilities to the user. Many smartglasses include displays that add information alongside or to what the wearer sees. Alternatively, smartglasses are sometimes defined as glasses that are able to change their optical properties, such as smart sunglasses that are programmed to change tint by electronic means. Alternatively, smartglasses are sometimes defined as glasses that include headphone functionality.
