Trådløse signaler med modulerede og pulserende radioogmikrobølger er en ny form for luftforurening, og strålernerammer os døgnet rundt fra alskens sendere. Vi deltageralle i et globalt trådløst eksperiment!Stråler kan ikke ses, høres eller mærkes af de fleste, mende er en helbredstrussel for sårbare grupper som gravide,børn og el-overfølsomme mennesker.Det kan være nødvendigt med afskærmning mod stråler.Det må være ansvarspådragende, når WHO og Sundhedsstyrelsenfrasorterer dokumentation fra biofysisk forskningom biologiske skadevirkninger og accepterer ”no risk”propaganda ud fra manipuleret kræftmobilforskning.Sundhedsstyrelsen svigter befolkningen og især sårbare grupper,når der undlades forebyggelse af skadevirkninger vedbestråling. Der skal forebygges Nu!Det trådløse marked udbygges og styres af EU direktiverog forordninger, og lige nu gælder det mobile bredbåndssenderesom WiFi og Wlan, der giver internet adgang.Vi borgere kan ikke indhente oplysninger om, hvor dissesendere sættes op i kommunen, men selvfølgelig skal vivide, hvilke bestrålinger vi udsættes for, og hvor vi bestrålesfra.Børn skal ikke bestråles med mikrobølger i hverken skoler,daginstitutioner, tog eller busser.Der findes allerede el-overfølsomme miljøflygtninge!

Dagligt fristes vi af store annoncer om trådløse produkter. Med mobile bredbånd kan der surfes på nettet med smartphones og en bærbar computer, og de unge føler sig usårlige.Døgnet rundt udsættes vi for trådløs forurening. Er trådløse markeder vigtigere end sundhed og miljø? Vi misinformeres om sikre grænseværdier, som ikke findes. Vi fodres med forskningsskabte myter, fakta frasorteres og lægelige advarsler ignoreres.Det er på høje tid med forebyggelse. Børn kan ikke beskytte sig selv imod en usynlig og ukendt fare.

In the vast blue ocean, ships of different navies operate far from each other and are generally not in visual range. However, a ship can be uniquely identified based on a number of emissions that are characteristic to each and are called signatures. These include acoustic signature from machinery and flow, heat or infrared signature from exhaust, radar cross section from hull surfaces, magnetic signature from hull material, electric signature from corrosion protection systems etc. These signatures are used by surveillance and tracking sensors for attacking ships in general and warships, in particular. Survivability at sea requires management of all platform signatures to produce a net effect of reduced vulnerability. Anti-ship missiles pose the greatest threat to ships at sea. Prior to the Second World War, studies were carried out in parallel on the use of radar and infrared seekers in missiles for detection, identification and homing. For the materials available in the 1940s, radar seekers gave better results and hence, have become the standard fit. Over the years, advances in material sciences have improved the capabilities of infrared seekers and today, missiles have several guidance/seeker options that include radar, electro- optical camera and infrared imaging. Infrared homing is preferred for terminal guidance because of its inherent immunity to jamming techniques. A stealthy naval platform remains undetected and therefore can be deployed closer to the target to fulfill its mission with lesser risk of damage and associated causalities. Signatures used for ship detection include both underwater and above water. Signatures used by underwater weapons like torpedoes and mines are acoustics, magnetics, wake homing and extremely low frequency emissions (ELFE). Anti-ship missiles use above water signatures that include laser cross section (LCS), radar cross section (RCS), air borne noise and infrared (IR).

Traffic control devices (TCDs) are very critical for the safe and efficient transportation of people and goods. The Manual on Uniform Traffic Control Devices (MUTCD), by setting minimum standards and providing guidance, ensures uniformity of traffic control devices across the nation. The use of uniform TCDs (messages, locations, sizes, shapes, and colors) helps reduce crashes and congestion, and improves the efficiency of the surface transportation system. Uniformity also helps reduce the cost of TCDs through standardization. The information contained in the MUTCD is the result of years of practical experience, research, and/or the MUTCD experimentation process. This effort ensures that TCDs are visible, recognizable, understandable, and necessary. The MUTCD is a dynamic document that changes with time to address contemporary safety and operational issues.

Modern communication systems use hybrid techniques which involves both radio frequency (RF) and optical systems to transport information. Optical fiber is widely used to transport microwave signals because of its low loss and wide bandwidth. A hybrid communication system consists of a coaxial cable network and optical fiber network. Coaxial cables are used for RF communication whereas optical fibers for optical communication. This integrated RF and optical solution will give more speed, higher bandwidth and better mobility. RF to optical and optical to RF conversion are the key techniques used in any hybrid communication system. We have developed a multipurpose versatile device for hybrid communication system. Utilizing RF and optical techniques, a smart system was also developed for measurement and data transfer for health care applications.Convergence of optical and RF communication systems result in the transmission of high speed microwave signals over optical fiber. Radio over fiber technologies supports the distribution of broadband RF/wireless signals. Present hybrid communication system is essentially a combination of RF coaxial cable network and optical fiber network. RF to optical and optical to RF conversion is the main techniques used in hybrid communication system. Objective of the present work is to develop RF to optical (optical transmitter) and optical to RF converter (Optical Receiver) modules for various applications in communication systems and its measurements. We have designed and developed a low cost intensity modulated transmitter using DFB laser for analog optical communication link. Optical receiver was developed with a high speed PIN photodiode. Appropriate impedance matching circuit is designed for both transmitter and receiver to achieve wide band frequency response. Transmitter and receiver were designed by modelling the circuits with microwave simulation tool called Ansoft designer. Performance of the system was verified by analyzing transmission and reflection characteristics.

"How the largest man-made constellation in the heavens was built by dreamers in the Arizona Desert, targeted for destruction by panicked executives, and saved by a single Palm Beach retiree who battled Motorola, cajoled the Pentagon, wrestled with thirty banks, survived an attack by Congress, infiltrated the White House, found allies through the Black Entertainment Network, and wooed a mysterious Arab prince to rescue the only phone that links every inch of the planet."

At present, the communication systems in Aircrafts involve messy wiring. Such wiring systems require more time for construction and leads to considerable time delay in faulty location. In addition to the cost of lengthy wires, many accidents have been reported due to faulty wiring in aircrafts. To overcome these difficulties, researches are carried out all over the world to develop an efficient wireless communication system. In this book, it is proposed to develop a design procedure for wireless communication system for aircrafts using space division multiple access. Noise from external sources interfere the signals transmitted and the quality of the communication gets degraded. The major aim of this book is to identify and eliminate the additive white Gaussian noise in the communication channel and thereby enhance the quality of wireless communications in the Aircraft.

Radio is the technology of using radio waves to carry information, such as sound, by systematically modulating the properties of electromagnetic energy waves transmitted through space, such as amplitude, frequency, phase, or pulse width. Radio communication touches the sky day by day. Today the concept of communication has totally changed because of the advancement of internet technology. Internet radio is a baby of this millennium holding the hands of an older technology. Internet radio touches all the possible perspectives of media convergence. Internet radio is also called web radio, net radio, streaming radio, and online radio. It is a digital audio service transmitted via the internet. Broadcasting on the Internet is usually referred to as webcasting since it is not transmitted broadly through wireless.It can either be used as a standalone device running through the internet, or as software running through a single computer system. A podcast is an episodic series of digital audio or video files which a user can download and listen to. It is often available for subscription, so that new episodes are automatically downloaded via web syndication to the user's own computer or mobile phone. On the other hand live streaming refers to online streaming media simultaneously recorded and broadcast real time. The context of the present thesis is about how the idea of internet radio/audio has taken root in the field of education, entertainment and information.The internet radio, was in its infancy at the beginning of this millennium, when it was adopted only by people in the developed nations. Of late, it has become affordable in the developing nations like India and other Countries as well. The latter half of the twentieth century witnessed the power of radio broadcasting in the field of development of communication India's Green Revolution in the 60's and 70's, owe a lot to Radio.
