Wireless Networks: How Do They Work? by Ron King
Wireless networks use radio waves instead of wires to transmit data between computers. Here's how: The Binary Code: 1s and 0s It's well known that computers transmit information digitally, using binary code: ones and zeros. This translates well to radio waves, since those 1s and 0s can be... More importantly for this example, though, it is a binary system, just as a computer system is. ... You plug in a combined radio receiver and transmitter, and the computer is able to send out its equivalent of dots and dashes (bits, in computer-speak) to get your data from here to there.

A Brief Introduction To Bluetooth by Oliver Dvorak
Bluetooth was designed to allow low bandwidth wireless connections to become easy to use so even those who are new to wireless can use them. Version one.One of Bluetooth describes a low power, short range wireless networking technology that uses radio waves to send data at rates up to 720... Also known for its worldwide operation, Bluetooth radio operates in the 2.four GHz frequency band, which is license free and reachable to any type of radio system in the world. ... The size of the Bluetooth radio is remarkable, as a Bluetooth radio can be built into 1 or two very small microchips then...

Wireless Networks by Elizabeth Morgan
The information age has been revolutionized not just by the power of computers to process data, but also by the power of communication amongst computers. This communication is responsible for the proliferation of computer networks. Sharing of information, sharing of resources (both software and... Wireless communication technologies used in wireless networks include analog cellular, digital cellular, Cellular Digital Packet Data (CDPD), mobile radio networks, personal communication services (PCS), satellite, microwave systems and local multipoint distribution systems (LMDS).

How To Decode The MSF-60 Radio Time Signal by David Evans
The MSF-60 atomic clock synchronised radio time transmission is utilised by many NTP Time Server and PC computer systems to provide accurate synchronisation of time critical applications. This article describes how the MSF-60 time signal is decoded by NTP Time Server and computer systems to... The data is transmitted as on-off carrier modulated, pulse-width coded data signal. ... The radio signal is maintained by BT Radio Engineering Services under contract from the National Physics Laboratory (NPL).

Radio Frequency Identification Basics by James Hunt
Radio Frequency Identification or RFID is the use of radio waves to identify objects. This means, unlike a barcode, one can track an item without actually having to come in contact with it. The way it works is that an identifying serial number is stored in a microchip which is then attached to... Radio Frequency Identification isn’t new. ... Businesses that use this system will be able to track products throughout the whole manufacturing process, from the beginning of the conveyor belt to the packaging and beyond.

Radio Frequency Identification (RFID) by Jith Crs
The term Radio Frequency Identification is used for automatically identifies an object that transmits the identification (in the form of a unique serial number) of an object wirelessly, using radio waves. Radio Frequency IDentification abbreviated, as RFID is a Dedicated Short Range... A feasible solution is putting the data on silicon chips and contact less transfer of data between the data carrying device and its reader. ... RFID TECHNOLOGY AND ARCHITECTURE: In an RFID system, the RFID tag, which contains the tagged data of the object, generates a signal containing the respective...

RFID Readers Guide by Mansi Aggarwal
RFID or Radio Frequency Identification is a constantly evolving technology that has made its foray into our lives from the inner circles of science very rapidly. It is basically one of the automatic identification systems like bar codes, smart cards, etc. ... The system works by transmitting the data stored in the tags to a RFID reader that in turn reads it and processes the data according to the application’s specifications. ... The system also includes an interrogator, which has a certain range in which it detects the RFID tag, activates it, and receives the response.

Evaluating Telemetry Data by Keith Londrie
The word Telemetry, like all English words, is a culmination of the Greek words tele meaning remote and metron meaning measure. Thus, Telemetry is the science and technology of remote measurement, and relaying of data by wire, radio, or other means from inaccessible locations, as from orbiting... For instance, a flag in the data may indicate which of several formats the data appear in, and the location of other data items within the record depends on this format. ... A so-called handler, collects, formats and stores the data in a dedicated buffer, and then transfers the data to the...

Bluetooth Makes The Wires Disappear by Khieng Chho
While relatively new to the ears of common consumers, Bluetooth technology has been around for several years and number of products that support this application grows year after year. Various technology-oriented companies advertise Bluetooth-enabled PDAs, laptops and mobile phones. ... Bluetooth radio hops at a faster pace compared to other systems operating in the similar frequency level, as it uses shorter packets. ... Bluetooth gadgets operate on 2.4 GHz radio signals similar to many cordless telephones and 802.11 b/g wireless networking systems.

The SIM card and My Curiosity's Satisfaction by Liuba Ceban
Have you ever thought what’s the deal with that golden-colored plate, inserted to your mobile phone? I did, so I looked for the information and now I can share with you what I found out. When I was a little girl, I was always interested to know what is inside of the different devices and tools... The other part of the memory can be used for data storage, like my phone numbers or SMSs. ... Sometimes this curiosity led me to disclose the radio, my father was listening to all the time, being in the garage.
