hackers are from the noise. This Project describes a design of effective security for data communication by designing standard algorithm for encryption and decryption. R.F. is a PAN technology based on the IEEE 802.15.4 standard. Unlike Bluetooth or wireless USB devices‚ R.F. devices have the ability to form a mesh network between nodes. Meshing is a type of daisy chaining from one device to another. This technique allows the short range of an individual node to be expanded and multiplied‚ covering a

Wired and Wireless Media Wired and wireless media both provide means of transporting data. Though both provide benefits in certain areas‚ neither is particularly better than the other. It is important for organizations to utilize both methods of media to maximize what benefits each provides while minimizing that same media types short comings. Anders (2010) uses six metrics to compare wireless and wired media: range‚ installation effort and flexibility‚ data volume‚ availability of information in

CONCEPT OF WIRELESS ELECTRICITY (Wi-Tricity) Our forefathers marveled at the invention of glowing light bulbs by Thomas Edison in 1879. However‚ to us 21st centurions‚ the light bulb is nothing out of the ordinary. When computers‚ cell phones‚ laptops‚ iPods‚ etc. were invented our antennas tweaked. Now this is what you call invention! However‚ as time’s progressing we are getting used to these devices. In fact‚ charging all these appliances has become so very cumbersome. Each appliance has its

Google in China Q1: What philosophical principles did Google’s managers adopt when deciding that the benefits of operating in China outweighed the costs. Google’s managers made the decision to operate in China because of vast profit assumptions and predictions. Therefore they had to adopt to the local Chinese habits and the governments restraints and regulations. But to which philosophical approach does this behavior refers to? Maybe on the first sight it seems to be either the Cultural Relativism

Wireless energy transfer or wireless power is the transmission of electrical energy from a power source to an electrical load without artificial interconnecting conductors. Wireless transmission is useful in cases where interconnecting wires are inconvenient‚ hazardous‚ or impossible. The most common form of wireless power transmission is carried out using direct induction followed by resonant magnetic induction. Other methods under consideration include electromagnetic radiation in the form of microwaves or lasers
