Scatternet
A scatternet is a type of ad hoc computer network consisting of two or more piconets. The terms "scatternet" and "piconet" are typically applied to Bluetooth wireless technology. Description A ''piconet'' is the type of connection that is formed between two or more Bluetooth-enabled devices such as modern cell phones. Bluetooth enabled devices are "peer units" in that they are able to act as either master or slave. However, when a piconet is formed between two or more devices, one device takes the role of the 'master', and all other devices assume a 'slave' role for synchronization reasons. Piconets have a 7 member address space (3 bits, with zero reserved for broadcast), which limits the maximum size of a piconet to 8 devices, i.e. 1 master and 7 slaves. A ''scatternet'' is a number of interconnected piconets that supports communication between more than 8 devices. Scatternets can be formed when a member of one piconet (either the master or one of the slaves) elects to parti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bluedating
Wireless dating, Widating or Bluedating (from ''Bluetooth'') is a form of dating which makes use of mobile phone and Bluetooth technologies. Subscribers to the service enter details about themselves and about their ideal partner, as they would for other on-line dating services. When their mobile phone comes in the vicinity of that of another subscriber (a radius of about 10 meters) the phones exchange details of the two people. If there is a match, then both users are alerted and can seek each other out and directly chat using Bluetooth ( bluechat). Settings can include an option which restricts alerts to subscribers who have a friend in common. There is an implementation of wireless dating called Serendipity being developed by MIT's Media Lab in Cambridge, Massachusetts (Reported in ''New Scientist Magazine'' 20 March 2004.). In 2022 the app Luvabuzza was released, the first fully functional Bluedating app, based on Bluetooth Low Energy, which is a databurst in milliseconds. The ...

Piconet
A piconet is an ad hoc network that links a wireless user group of devices using Bluetooth technology protocols. A piconet consists of two or more devices occupying the same physical channel (synchronized to a common clock and hopping sequence). It allows one ''master'' device to interconnect with up to seven active '' slave'' devices. Up to 255 further slave devices can be inactive, or ''parked'', which the master device can bring into active status at any time, but an active station must go into parked first. Some examples of piconets include a cell phone connected to a computer, a laptop and a Bluetooth-enabled digital camera A digital camera is a camera that captures photographs in digital memory. Most cameras produced today are digital, largely replacing those that capture images on photographic film. Digital cameras are now widely incorporated into mobile devices ..., or several PDAs that are connected to each other. Overview A group of devices are connected via Bl ...

Ireland
Ireland ( ; ga, Éire ; Ulster Scots dialect, Ulster-Scots: ) is an island in the Atlantic Ocean, North Atlantic Ocean, in Northwestern Europe, north-western Europe. It is separated from Great Britain to its east by the North Channel (Great Britain and Ireland), North Channel, the Irish Sea, and St George's Channel. Ireland is the List of islands of the British Isles, second-largest island of the British Isles, the List of European islands by area, third-largest in Europe, and the List of islands by area, twentieth-largest on Earth. Geopolitically, Ireland is divided between the Republic of Ireland (officially Names of the Irish state, named Ireland), which covers five-sixths of the island, and Northern Ireland, which is part of the United Kingdom. As of 2022, the Irish population analysis, population of the entire island is just over 7 million, with 5.1 million living in the Republic of Ireland and 1.9 million in Northern Ireland, ranking it the List of European islan ...

IEEE 802
IEEE 802 is a family of Institute of Electrical and Electronics Engineers (IEEE) standards for local area networks (LAN), personal area network (PAN), and metropolitan area networks (MAN). The IEEE 802 LAN/MAN Standards Committee (LMSC) maintains these standards. The IEEE 802 family of standards has had twenty-four members, numbered 802.1 through 802.24, with a working group of the LMSC devoted to each. However, not all of these working groups are currently active. The IEEE 802 standards are restricted to computer networks carrying variable-size packets, unlike cell relay networks, for example, in which data is transmitted in short, uniformly sized units called cells. Isochronous signal networks, in which data is transmitted as a steady stream of octets, or groups of octets, at regular time intervals, are also outside the scope of the IEEE 802 standards. The number 802 has no significance: it was simply the next number in the sequence that the IEEE used for standards project ...

Personal Area Network
A personal area network (PAN) is a computer network for interconnecting electronic devices within an individual person's workspace. A PAN provides data transmission among devices such as computers, smartphones, tablets and personal digital assistants. PANs can be used for communication among the personal devices themselves, or for connecting to a higher level network and the Internet where one master device takes up the role as gateway. A PAN may be wireless or carried over wired interfaces such as USB. A wireless personal area network (WPAN) is a PAN carried over a low-powered, short-distance wireless network technology such as IrDA, Wireless USB, Bluetooth or ZigBee. The reach of a WPAN varies from a few centimeters to a few meters. WPANs specifically tailored for low-power operation of the sensors are sometimes also called low-power personal area network (LPPAN) to better distinguish them from low-power wide-area network (LPWAN). Wired Wired personal area networks provi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Java ME

JSR-82
Java APIs for Bluetooth Wireless Technology (JABWT) is a J2ME specification for APIs that allows Java MIDlets running on embedded devices such as mobile phones to use Bluetooth for short-range wireless communication. JABWT was developed as JSR-82 under the Java Community Process. JSR 82 implementations for Java 2 Platform Standard Edition (J2SE) are also available. Background The original Java Specification Request (JSR-82) was submitted by Motorola and Sun Microsystems, and approved by the Executive Committee for J2ME in September 2000. JSR-82 provided the first standardized Java API for Bluetooth protocols, allowing developers to write applications using Bluetooth that work on all devices conforming to the specification. The first version of JSR-82 was released in March 2002. The most recent update to JSR-82, Maintenance Draft Review 4, was released in March 2010. The specification, reference implementation, and Technology Compatibility Kit (TCK) are maintained at Motorola ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Java Programming Language
Java is a high-level, class-based, object-oriented programming language that is designed to have as few implementation dependencies as possible. It is a general-purpose programming language intended to let programmers ''write once, run anywhere'' ( WORA), meaning that compiled Java code can run on all platforms that support Java without the need to recompile. Java applications are typically compiled to bytecode that can run on any Java virtual machine (JVM) regardless of the underlying computer architecture. The syntax of Java is similar to C and C++, but has fewer low-level facilities than either of them. The Java runtime provides dynamic capabilities (such as reflection and runtime code modification) that are typically not available in traditional compiled languages. , Java was one of the most popular programming languages in use according to GitHub, particularly for client–server web applications, with a reported 9 million developers. Java was originally develope ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
