Wireless Network Security

History Of Mobile Phones ... Mobile phone history is often divided into generations (first, second, third and so on) to mark significant step changes in capabilities as the technology improved. Pioneers of radio telephony By 1930, telephone customers in the United States could place a call to a passenger on a liner in the Atlantic Ocean...

Google ... Google was first incorporated as a privately held company on September 4, 1998, and its initial public offering followed on August 19, 2004. At that time Larry Page, Sergey Brin, and Eric Schmidt agreed to work together at Google for 20 years, until the year 2024...

Internet Access ... Broadband Internet access may give access to Internet services such as: Much faster world wide web browsing Telephony, radio, television and videoconferencing Virtual private networks and remote systems administration Online gaming especially massively multiplayer online role-playing games which are interaction-intensive "Broadband penetration" is now treated as a key economic indicator. Even though information signals generally travel nearly the speed of light in the medium no matter what the bit rate, higher rate services are often marketed as "faster" or "higher speeds"...

Network Security ... Once authenticated, a firewall enforces access policies such as what services are allowed to be accessed by the network users. Though effective to prevent unauthorized access, this component may fail to check potentially harmful content such as computer worms or Trojans being transmitted over the network...

Intel ... Intel was an early developer of SRAM and DRAM memory chips, and this represented the majority of its business until 1981. Although Intel created the world's first commercial microprocessor chip in 1971, it was not until the success of the personal computer (PC) that this became its primary business...

International Space Station ... The ISS serves as a microgravity and space environment research laboratory in which crew members conduct experiments in biology, human biology, physics, astronomy, meteorology and other fields. The station is suited for the testing of spacecraft systems and equipment required for missions to the Moon and Mars...

Encryption ... In many contexts, the word encryption may also implicitly refer to the reverse process, decryption e.g. “software for encryption” can typically also perform decryption ...

Voice Over IP ... Internet telephony refers to communications services —voice, fax, SMS, and/or voice-messaging applications— that are transported via the Internet, rather than the public switched telephone network (PSTN). The steps involved in originating a VoIP telephone call are signaling and media channel setup, digitization of the analog voice signal, encoding, packetization, and transmission as Internet Protocol (IP) packets over a packet-switched network...

Mobile Phone Features ... The common components found on all phones are: A battery, providing the power source for the phone functions. An input mechanism to allow the user to interact with the phone...

Resonant Inductive Coupling ... Resonant energy transfer is the operating principle behind proposed short range wireless electricity systems such as WiTricity and systems that have already been deployed, such as passive RFID tags and contactless smart cards...

Photophone ... On April 1, 1880, and also described by plaque as occurring on June 3, Bell's assistant transmitted the world's first wireless telephone message to him on their newly invented form of telecommunication, the far advanced precursor to fiber-optic communications that came into widespread use during the 1980s... The wireless call was sent from the roof of the Franklin School to the window of Bell's laboratory, some 213 metres (700 ft) away...

Mobile Phone ... In addition to telephony, modern mobile phones also support a wide variety of other services such as text messaging, MMS, email, Internet access, short-range wireless communications (infrared, Bluetooth), business applications, gaming and photography...

Mobile Banking ... Mobile banking has until recently (2010) most often been performed via SMS or the Mobile Web. Apple's initial success with iPhone and the rapid growth of phones based on Google's Android (operating system) have led to increasing use of special client programs, called apps, downloaded to the mobile device...

Network Performance ... The following list gives examples of Network Performance measures for a circuit-switched network and one type of packet-switched network, viz. ATM: Circuit-switched networks: In circuit switched networks, network performance is synonymous with the grade of service...

Mobile Robot ... The device may be plugged directly into the robot, may be a wireless joystick, or may be an accessory to a wireless computer or other controller... Such robots are often part of the wireless enterprise network, interfaced with other sensing and control systems in the building...

Wireless Energy Transfer ... The most common form of wireless power transmission is carried out using direct induction followed by resonant magnetic induction...

History Of Radio ... In 1895, Marconi built a wireless system capable of transmitting signals at long distances (1.5 mi./ 2.4 km)... Early radio telegraphy and telephony The term wireless telegraphy is a historical term used today to apply to early radio telegraph communications techniques and practices, particularly those used during the first three decades of radio (1887 to 1920) before the term radio came into use... Turn of the 19th to 20th century Around the turn of the 19th to 20th century, the Slaby-Arco wireless system was developed by Adolf Slaby and Georg von Arco...

Computer Network ... Networks may be classified according to a wide variety of characteristics such as the medium used to transport the data, communications protocol used, scale, topology, and organizational scope. Communications protocols define the rules and data formats for exchanging information in a computer network, and provide the basis for network programming...

Radio-frequency Identification ... RFID tags are used in many industries. An RFID attached to an automobile during production can be used to track its progress through the assembly line...

History Of The Telephone ... A different device, the tin can telephone, or 'lover's phone', has also been known for centuries. It connected two diaphragms with a taut string or wire, which transmitted sound by mechanical vibrations from one to the other along the wire, and not by a modulated electrical current...

Wireless Telegraphy ... Wireless telegraphy originated as a term to describe electrical signaling without the electric wires to connect the end points... Wireless telegraphy rapidly came to mean Morse code transmitted with Hertzian waves (electromagnetic waves) decades before it came to be associated with the term radio... Wireless telegraphy is still used widely today by amateur radio hobbyists where it is commonly referred to as radiotelegraphy, continuous wave, or just CW...

Cryptanalysis ... Cryptanalysis is also used to refer to any attempt to circumvent the security of other types of cryptographic algorithms and protocols in general, and not just encryption. However, cryptanalysis usually excludes methods of attack that do not primarily target weaknesses in the actual cryptography, such as bribery, physical coercion, burglary, keystroke logging, and social engineering, although these types of attack are an important concern and are often more effective than traditional cryptanalysis...
