[prev] [prev-tail] [tail] [up] Chapter 4 Fading and Shadowing Fading is a significant part of any wireless communication design; it is important to predict what type of fading may occur‚ and if possible use a wireless standard capable of providing remedies for the fades. When no remedies are possible‚ it may be important to predict the likelihood of outage. We will review here several types of fading and provide models to predict their impact. 4.1 Large-Scale Shadowing We start with

Ancient life was all silence. In the nineteenth century‚ with the invention of the machine. Noise was born. Today‚ Noise triumphs and reigns supreme over the sensibility of men. One of the biggest and most influential of these machine inventions was the theramin (or thereminvox). The theremin was one of the biggest cornerstones for electronic music and pioneered future generations of electronic and electrivally amplified music. It is named after its Russian inventor‚ Professor Léon Theremin‚ who

What Factors Affect AM And FM Radio Reception? Background Information Communications are carried by waves. One type of communication is AM and FM radio. AM and FM radio’s use radio waves. A radio wave is an electromagnetic wave propagated by an antenna at various frequencies. In AM (amplitude modulated) radio waves‚ the audio signal changes the amplitude of the carrier wave. In FM (frequency modulated) radio waves‚ the audio signal changes the frequency of the carrier wave. Australia’s broadcast

A Report on the movie The Perfect Storm Purpose: To watch a popular Hollywood natural disaster movie and review and summarize the scientific merit of it in a report‚ for my report I chose The Perfect Storm. A movie that is based on the actual storm in late October 1991 later called “The Perfect Storm” (Viets 2000). Also to comment on how realistic the movies’ storyline‚ effects and scientific merit when compared to the real life disaster which it is trying to recreate. Introduction In late

Mobile phone tracking tracks the current position of a mobile phone even on the move. To locate the phone‚ it must emit at least theroaming signal to contact the next nearby antenna tower‚ but the process does not require an active call. GSM localisation is then done bymultilateration based on the signal strength to nearby antenna masts.[1] Mobile positioning‚ i.e. location based service that discloses the actual coordinates of a mobile phone bearer‚ is a technology used bytelecommunication companies
