War-driving
Wardriving is the act of searching for Wi-Fi wireless networks, usually from a moving vehicle, using a laptop or smartphone. Software for wardriving is freely available on the internet. Warbiking, warcycling, warwalking and similar use the same approach but with other modes of transportation. Etymology ''War driving'' originated from wardialing, a method popularized by a character played by Matthew Broderick in the film ''WarGames'', and named after that film. War dialing consists of dialing every phone number in a specific sequence in search of modems. Variants ''Warbiking'' or ''warcycling'' is similar to wardriving, but is done from a moving bicycle or motorcycle. This practice is sometimes facilitated by mounting a Wi-Fi enabled device on the vehicle. ''Warwalking'', or ''warjogging'', is similar to wardriving, but is done on foot rather than from a moving vehicle. The disadvantages of this method are slower speed of travel (but leading to discovery of more infrequentl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Seattle - Columbia City WiFi
Seattle ( ) is a seaport city on the West Coast of the United States. It is the seat of King County, Washington. With a 2020 population of 737,015, it is the largest city in both the state of Washington and the Pacific Northwest region of North America. The Seattle metropolitan area's population is 4.02 million, making it the 15th-largest in the United States. Its growth rate of 21.1% between 2010 and 2020 makes it one of the nation's fastest-growing large cities. Seattle is situated on an isthmus between Puget Sound (an inlet of the Pacific Ocean) and Lake Washington. It is the northernmost major city in the United States, located about south of the Canadian border. A major gateway for trade with East Asia, Seattle is the fourth-largest port in North America in terms of container handling . The Seattle area was inhabited by Native Americans for at least 4,000 years before the first permanent European settlers. Arthur A. Denny and his group of travelers, subsequently kno ...

IPAQ
The iPAQ is a discontinued Pocket PC and personal digital assistant which was first unveiled by Compaq in April 2000. HP's line-up of iPAQ devices included PDA-devices, smartphones and GPS-navigators. A substantial number of devices were outsourced from Taiwanese HTC corporation. The name was borrowed from Compaq's earlier iPAQ Desktop Personal Computers. Following Hewlett-Packard's acquisition of Compaq, the product has been marketed by HP. The devices use a Windows Mobile interface. In addition to this, there are several Linux distributions that also operate on some of these devices. Earlier units were modular. Sleeve accessories were released called "jackets", which slide around the unit and add functionality such as a card reader, wireless networking, GPS, and extra batteries. Later versions of iPAQs have most of these features integrated into the base device itself, some including GPRS mobile telephony (SIM card slot and radio). History The iPAQ was developed by Co ...

Intel
Intel Corporation is an American multinational corporation and technology company headquartered in Santa Clara, California. It is the world's largest semiconductor chip manufacturer by revenue, and is one of the developers of the x86 series of instruction sets, the instruction sets found in most personal computers (PCs). Incorporated in Delaware, Intel ranked No. 45 in the 2020 ''Fortune'' 500 list of the largest United States corporations by total revenue for nearly a decade, from 2007 to 2016 fiscal years. Intel supplies microprocessors for computer system manufacturers such as Acer, Lenovo, HP, and Dell. Intel also manufactures motherboard chipsets, network interface controllers and integrated circuits, flash memory, graphics chips, embedded processors and other devices related to communications and computing. Intel (''int''egrated and ''el''ectronics) was founded on July 18, 1968, by semiconductor pioneers Gordon Moore (of Moore's law) and Robert Noyce ( ...

Geolocation
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 coordinate system, 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 Electronics, electronic methods including position lines and position circles, celestial navigation, radio navigation, and the use of satellite navigation systems. ...

Antenna (electronics)
In radio engineering, an antenna or aerial is the interface between radio waves propagating through space and electric currents moving in metal conductors, used with a transmitter or receiver. In transmission, a radio transmitter supplies an electric current to the antenna's terminals, and the antenna radiates the energy from the current as electromagnetic waves (radio waves). In reception, an antenna intercepts some of the power of a radio wave in order to produce an electric current at its terminals, that is applied to a receiver to be amplified. Antennas are essential components of all radio equipment. An antenna is an array of conductors ( elements), electrically connected to the receiver or transmitter. Antennas can be designed to transmit and receive radio waves in all horizontal directions equally (omnidirectional antennas), or preferentially in a particular direction ( directional, or high-gain, or “beam” antennas). An antenna may include components not connec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
