In addition to the frequency hopped and direct sequence, spread spectrum multiple access technique, there are certain other hybrid combinations that provide the advantage in the area of cellular mobile communication system. The available wideband spectrum is divided in to a number of subspectras with smaller bandwidth. Frequency Hopped Multiple Access Technique (FHMAT) consists of a direct sequence modulated signal whose center frequency is made to hop periodically in a pseudorandom fashion. In this
Although there are many technologies in tracking, for this research I will be discussing Radio Frequency Identification (RFID) and Universal Product Code. There are major differences and comparisons between these two technologies which define both. Though both of these technologies are widely used within numerous industries, they are used differently since they are so different. For example, the government (United States Postal System), military, private companies (such as Wal-Mart, Target and
Technology and the Media In this essay, British historian and broadcaster Asa Briggs looks at how technological advances made in recent decades have created a revolution in the media, allowing people to communicate in ways they had never dreamed of. Briggs notes that although these new modes of communication—including the television, the personal computer, the Internet, and other digital technologies—are available throughout many parts of the world, these media may be used in different ways depending
A) RFID refers to radio-frequency identification and it belongs to Automatic Identification and Data Capture (AIDC) group of technology. This technology is able to scan objects automatically, collect data about the objects and store those data straightforward into the computer systems, this is done with almost no help from human. As seen in the picture below, there are 3 components in this system which help it to achieve all this work, these are RFID tag or label, RFID reader and an antenna. Inside
Radio frequency identification (RFID) is a computerized ID innovation that uses radio recurrence waves to exchange information between an onlooker and things that have RFID gadgets, or tags, joined. The tags hold a microchip and receiving wire, and work at universally distinguished standard frequencies. Barcodes are much smaller, lighter and easier than RFID but RFID offers significant advantages. One major advantage of RFID is that the innovation doesn't oblige any observable pathway the tags could
Computers and Firefighting It seems that the advances of today are moving far more rapidly than people have ever thought about. The only question is that how much farther can we go in the advancement of computer technology to support people. One of the ways to support people is in the area of Firefighting. In this field the firemen with help of computers is allowed to help civilians when they are in need. The job of now is becoming a little safer to do because of newly advances by computers
How is Bluetooth a modern technological application of physics? Introduction Bluetooth was invented in 1994 that replaces cable communications with wireless technology. (Ericsson, 1994) Bluetooth creates a wireless personal area network (PAN) that allows exchange of information among individuals and therefore is commonly used for short-range communication among mobile phones, laptops, PDAs and other portable and fixed devices. (Layton & Franklin, [date unknown]) Physics plays an important
The use of light as a communication media used in China Great Wall distance more than 7300 km with in 1 hour to sent signal from one tower to another. In the late 20th century optical communication took back in to the seat for its advantages over coaxial transport and other electrical communication system. In 1966, Kaw and Hockman proposed the idea of using optical fiber light wave communication and their prediction was data loss 20dB/km [12]. In late 1980s to 1990s, coherent detection communication
Wireless Technology Wireless technology is an industry that has seen much growth and progress in the years following the inception of the internet and cell phones. Our society has progressed to the point to where we can no longer function without this technology. Business, travel, and everyday life now are dependant on wireless technology. Wireless technology is just what its name implies, communicating or computing without wires and phone lines. Wireless technology uses a variety of different
Scope and Objective Wireless local area networks (WLANs) have the potential to improve the flexibility, productivity, and the quality of work life of an enterprise (Sage Research Staff, 2001). Berean Institute is a typical two year college with about a staff of sixty eight employees and 250 students per semester. Berean teaches cosmetology, barbering and the latest software and hardware technology, which is located in Philadelphia, Pennsylvania. Berean currently has two locations in the Philadelphia
