Eddystone (Google)
Eddystone was a Bluetooth Low Energy beacon profile released by Google in July 2015. In December 2018 Google stopped delivering both Eddystone and Physical Web beacon notifications. The Apache 2.0-licensed, cross-platform, and versioned profile contained several frame types, including ''Eddystone-UID'', ''Eddystone-URL'', and ''Eddystone-TLM''. ''Eddystone-URL'' was used by the Physical Web project, whereas ''Eddystone-UID'' was typically used by native apps on a user's device, including Google's first party apps such as Google Maps. Background The format was named after the Eddystone Lighthouse in the UK, motivated by the simplicity of a lighthouse-signal and its one-directional nature. Technical details Though similar to the iBeacon profile released by Apple in 2013, Eddystone can be implemented without restriction. Eddystone also contains a telemetry frame (''Eddystone-TLM'') designed for reporting on a beacon's health, including, for example, battery level. Like other be ...

Google Play Services
Google Play Services is a proprietary software package produced by Google for installation on Android devices. It consists of background services and libraries for use by mobile apps running on the device When it was introduced in 2012, it provided access to the Google+ APIs and OAuth 2.0. It expanded to cover a variety of Google services, allowing applications to communicate with the services through common means. The packages' services include location tracking and geofencing, single sign-on account services, user health and fitness tracking, payment processing, integrated advertising and security scanning. Many apps on Android devices depend on the use of Google Play Services, and the package requires the user to use a Google Account and agree to Google's terms of service. Distributing Google Play Services on an Android device requires a license from Google, which contractually prohibits device producers from producing Android devices that are incompatible with Google's An ...

Ubiquitous Computing
Ubiquitous computing (or "ubicomp") is a concept in software engineering, hardware engineering and computer science where computing is made to appear anytime and everywhere. In contrast to desktop computing, ubiquitous computing can occur using any device, in any location, and in any format. A user interacts with the computer, which can exist in many different forms, including laptop computers, tablets, smart phones and terminals in everyday objects such as a refrigerator or a pair of glasses. The underlying technologies to support ubiquitous computing include Internet, advanced middleware, operating system, mobile code, sensors, microprocessors, new I/O and user interfaces, computer networks, mobile protocols, location and positioning, and new materials. This paradigm is also described as pervasive computing, ambient intelligence, or "everyware". Each term emphasizes slightly different aspects. When primarily concerning the objects involved, it is also known as physical compu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radio Navigation
Radio navigation or radionavigation is the application of radio frequencies to determine a position of an object on the Earth, either the vessel or an obstruction. Like radiolocation, it is a type of radiodetermination. The basic principles are measurements from/to electric beacons, especially * Angular directions, e.g. by bearing, radio phases or interferometry, * Distances, e.g. ranging by measurement of time of flight between one transmitter and multiple receivers or vice versa, * Distance ''differences'' by measurement of times of arrival of signals from one transmitter to multiple receivers or vice versa * Partly also velocity, e.g. by means of radio Doppler shift. Combinations of these measurement principles also are important—e.g., many radars measure range and azimuth of a target. Bearing-measurement systems These systems used some form of directional radio antenna to determine the location of a broadcast station on the ground. Conventional navigation techniques a ...

Radio-frequency Identification
Radio-frequency identification (RFID) uses electromagnetic fields to automatically identify and track tags attached to objects. An RFID system consists of a tiny radio transponder, a radio receiver and transmitter. When triggered by an electromagnetic interrogation pulse from a nearby RFID reader device, the tag transmits digital data, usually an identifying inventory number, back to the reader. This number can be used to track inventory goods. Passive tags are powered by energy from the RFID reader's interrogating radio waves. Active tags are powered by a battery and thus can be read at a greater range from the RFID reader, up to hundreds of meters. Unlike a barcode, the tag does not need to be within the line of sight of the reader, so it may be embedded in the tracked object. RFID is one method of automatic identification and data capture (AIDC). RFID tags are used in many industries. For example, an RFID tag attached to an automobile during production can be used to track ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geopositioning
Geopositioning, also known as geotracking, geolocalization, geolocating, geolocation, or geoposition fixing, is the process of determining or estimating the geographic position of an object. Geopositioning yields a set of geographic coordinates (such as latitude and longitude) in a given map datum; positions may also be expressed as a bearing and range from a known landmark. In turn, positions can determine a meaningful location, such as a street address. Specific instances include: animal geotracking, the process of inferring the location of animals; positioning system, the mechanisms for the determination of geographic positions in general; internet geolocation, geolocating a device connected to the internet; and mobile phone tracking. Background Geopositioning uses various visual and electronic methods including position lines and position circles, celestial navigation, radio navigation, and the use of satellite navigation systems. The calculation requires measurements or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Facebook Bluetooth Beacon
The Facebook Bluetooth Beacon is a hardware beacon released by Facebook Facebook is an online social media and social networking service owned by American company Meta Platforms. Founded in 2004 by Mark Zuckerberg with fellow Harvard College students and roommates Eduardo Saverin, Andrew McCollum, Dustin M ... in 2015. The beacon uses a bluetooth connection to communicate with the Facebook app on the user's smartphone, informing it of the phone's location. The technology allows location-specific advertising to be pushed to the user's Facebook feed. In June 2015, Facebook gave free beacons to a number of businesses in the United States.
