differences between them. Antennas are included 3 types: omnidirectional‚ semi-directional‚ and highly-directional. Any antenna has three fundamental properties: gain‚ directional and polarization. Omnidirectional Antennas. We can use this antenna in a: point-multipoint link‚ warehouse‚ hotspot‚ trade show‚ airport. The omnidirectional antennas transmit a signal in all directions‚ it is known dipole ("non-directional") antenna. The most of common antenna with low gain are "Rubber Ducky"‚ vertically

The four communication models of McQuail’s are representations of the process of public communication. The most basic form is the transmission model‚ which is theorised by Claude Shannon and Warren Weaver. The transmission model ‘transmits a fixed

Bluetooth provides a way to connect and exchange information between devices such as mobile phones‚ telephones‚ laptops‚ personal computers‚ printers‚ GPS receivers‚ digital cameras. So the security of the Bluetooth becomes very important. We have different types of security for Bluetooth to protect the data over the transmission Here we discuss some of the Bluetooth

First developed in the 1970s‚ fiber-optic communication system have revolutionized the telecommunication industry and have played a major role in the advent of the information over age. Because of its advantages over electrical transmission‚ optical fibers have largely replaced copper wire communications in core networks in the developed world. The process of communicating using fiber-optics involves the following basic steps: Creating the optical signal involving the use of a transmitter

This makes the protections of digital intellectual property rights and content authentications have been a serious problem. Hence the technology of digital watermarking is received a large deal of attention. Generally‚ digital watermarking techniques are based on either spread spectrum methods or changing
