Conclusion
What is WI-FI
This is wireless fidelity.
Wi-Fi is a wireless network protocol often used for wireless local Area networks (WLANS).
It enables multiple devices to share a single high-speed Internet connection over a distance of about 300 feet.
WLANs are local area networks of PCs without wires.
Data transmission is through air using radio frequency or infrared frequency instead of wires.

ABSTRACT

OFDM (Orthogonal Frequency Division Multiplexing) is a modulation and multiple access technique that has been explored for over 20 years. Only recently has it been finding its way into commercial communications systems. OFDM, or multitone modulation, is presently used in a number of commercial wired and wireless applications. In order for any mobile system to create a rich user experience, it must provide ubiquitous, fast and user-friendly connectivity. OFDM has several unique properties that make it especially well suited to handle ....etc

Abstract
Traffic grooming in optical network has gained significance due to prevailing sub wavelength requirement of end users. Optical networks get upgraded to the latest technology slowly with time with only a subset of nodes being upgraded to the latest technology. The networks are ....etc

Definition
The concept of light tree is introduced in a wavelength routed optical network, which employs wavelength -division multiplexing (WDM).
Depending on the underlying physical topology networks can be classified into three generations:

a).First Generation: these networks do not employ fiber optic technology; instead they employ copper-based or microwave technology. E.g. Ethernet.
b).Second Generation: these networks use optical fibers for data transmission but switching is performed in electronic domain. E.g. FDDI.
c).Third Genera ....etc

ABSTRACT
The concept of a light-tree is introduced in a wavelength-routed optical network. A light-tree is a point-to-multipoint generalization of a lightpath. A lightpath is a point-to-point all-optical wavelength channel connecting a transmitter at a source node to a receiver at a destination node. Lightpath communication can significantly reduce the number of hops (or lightpaths) a packet has to traverse; and this reduction can, in turn, significantly improve the networkâ„¢s ....etc

ABSTRACT
A lightweight method for counting and localizing people using camera sensor networks is described in this article. a motion histogram is made use of by the algorithm for detecting the people based on motion and size criteria.the distribution of people in a roomis estimated by the motin histogram, given a threshod vaueof the pixels in a frame-differenced motion´ image. Ths the motion histogram is an averaged shifted histogram. good detection rates at low computational complexity is provided by the algorithmfor the users. The ....etc

ABSTRACT

Telecom infrastructure is a key catalyst for economic growth, and is one of the key focus areas for infrastructure development in developing countries. Telecom growth in these countries is hampered by the high capital cost of telecom equipment. There is a requirement for new telecom systems to be developed, keeping in view the affordability and the services required in these countries. corDECT is one such product, which is designed to be affordable to the common man in the developing economies, and provides all th ....etc

AUGMENTED REALITY
ABSTRACT

Video games have been entertaining us for nearly 30 years, ever since Pong was introduced to arcades in the early II 970â„¢s.Computer graphics have become much more sophisticated since then, and soon, game graphics will seem all too real. In the next decade, researchers plan to pull graphics out of your television screen or computer display and integrate them into real- world environments. This new technology called augmented reality, will further blur the line between what ....etc

Today, there is a general consensus that, in the near future, wide area networks (WAN)(such as, a nationwides backbone network) will be based on Wavelength Division Multiplexed (WDM) optical networks. One of the main advantages of a WDM WAN over other optical technologies, such as, Time Division Multiplexed (TDM) optical networks, is that it allows us to exploit the enormous bandwidth of an optical fiber (up to 50 terabits bits per second) with requiring electronic devices, which operate at extremely high speeds.

The concept of light tree ....etc
