What is Gi-Fi?

We all are very familiar with Wi-Fi and WiMax technology. These are used to transfer data at a faster rate. But the transfer of video files takes a lot of time. This leads to the development of a new technology called Gi-Fi. It has some advantages over Wi-Fi and other wireless technology. The Gi-Fi technology has faster information rate, low cost for short range transmission and consumes less power.

Gi-Fi is developed on an integrated wireless transceiver chip. In that a small antenna is used and both transmitter-receiver integrated on one chip which is fabricated using the complementary metal oxide semiconductor (CMOS) method. With Gi-Fi large video files are transferred within seconds. Read More

What is nanotechnology?

Have you heard about nanotechnology? It is the science and technology at the nanoscale that is concerning 1 to 100 nanometers. Nanotechnology and nanoscience is the application and study of very tiny things. And may be used across all the other science fields; like materials science, chemistry, physics, biology, and engineering.

Nanoscience and nanotechnology involve the power to check and to manage individual atoms and molecules. Everything on Earth is formed from atoms-the food we eat, the garments we wear, the buildings and homes we live in, and our own bodies. Read More

What is digital light processing?

We have heard about digital image processing. But have you heard about digital light processing? This technology may be a video technology owned, promoted and trademarked by Texas Instruments for video playback. DLP technology is employed in rear-projection HDTVs. Likewise as projector units. There are designs that use multiple DLP chips to feature extra resolution to the video image on the high end of front projectors. Read More

What is a tunable laser?

We all are familiar with laser and its applications. Lasers have a very important role in the health care industry. Also lasers are used in the communication field also. For instance, the wavelength of the light from the laser depends on the material of laser. Can you adjust the wavelength of the laser? This is possible by using a tunable laser.

Tunable lasers as the name suggests are lasers whose wavelengths are often tuned or varied. Also they play a very important role in optical communication networks. Moreover, recent enhancements in tunable laser technologies are enabling highly flexible and effective utilization of the huge increases in optical network capability brought by large-scale application of dense wavelength division multiplexing.

What is Generic Access Network?

Have you heard about Generic Access Network? It is an evolving wireless communications system within which mobile sets operate seamlessly between local area networks (LANs) and wide-area networks (WANs). Using GAN technology; a mobile phone subscriber will communicate by speech; data and multimedia through large-scale cellular and small-scale Wi-Fi systems. Usually, all handoffs between systems occur without disturbing the communications session.

GAN Technology

As GAN technology is implemented, cellular phone subscribers will expect improved coverage. The ability to use one phone set for all their voice communications. And maybe cheaper rates with a single bill for net and voice communications. Read More

What do you mean by rapid prototyping?

Have you heard about prototyping? It is an activity for making prototypes of software application. This activity may occur in software development that is comparable to prototyping as from other fields such as manufacturing. And mechanical engineering. Now have you heard about rapid prototyping?

Rapid Prototyping

Rapid prototyping is that the automatic construction of physical objects using solid freeform fabrication. And are used to manufacture models and prototype components. It takes virtual designs (from computer aided design (CAD) or from animation modeling software), transforms them into cross sections, still virtual, and so produce each cross section in physical space. One when subsequent until the model is finished. It’s a WYSIWYG method where the virtual model and the physical model correspond nearly identically. Read More

What is IP Telephony?

Have you heard about IP Telephony? It is a revolutionary technology that has the potential to fully rework the world’s phone systems. Internet telephone providers like Vonage have already been around for a little while and are growing steady. Major carriers like AT&T are already fixing internet telecommunication calling plans in many markets round the United States, and also the FCC is trying seriously at the potential ramifications of internet telecommunication service.

The interesting factor regarding internet telephony is that there’s not just one way to make a call. Read More

What is Mobile WiMax?

We all are familiar with wireless technology. Of these the hottest technology used today is the WiMAX technology. In fact, WiMAX systems are used to provide broadband access services to enterprise and residential customers in a cost-effective way. It could be a standardized wireless version of LAN meant primarily as an alternative to wired technologies (such as DSL, Cable Modems  and T1/E1 links) to supply broadband access to customer premises.

WiMAX

More strictly, WiMAX is a business trade organization formed by leading communications, component and equipment corporations to certify and market compatibility and interoperability of broadband wireless access equipment that conforms to the standards such as ETSI HIPERMAN and IEEE 802.16.

Intel Centrino- A New Wireless Technology

The world of technology looks for more and more improved technologies. As a result of the competition in many fields new technologies have arrived that reduces time, increase the speed and so on. One of those technologies is the Intel Centrino. Centrino is a new technology package from Intel that provides in-built wireless support for laptop computersl; and while creating it possible to run a laptop all day (up to seven hours) without battery recharge.

Through Centrino, Intel hopes to encourage companies and users to replace their current laptops with a newer, or more mobile version. Analyst recommends that a more mobile laptop may in time replace the personal computer also. Read More

ATM security by image processing

We all are familiar with ATM facilities. We use a secret pin number as a security measure in ATM system. From the view of security point, fingerprints and biological information normally represent sensitive data; and that needs to be protected. Biometrics technology permits verification and determination of one’s identity through physical characteristics. In order to put it simply, it use the human body in to his or her password. Read More
