Radio: a Form of Communication

The Radio was introduced to society because of the telegraph and the telephone. These inventions don’t do the same things but their similar branch of technology. “Radio technology began as “wireless telegraphy”. “It all started with the discovery of radio waves, electromagnetic waves that have the capacity to transmit music, speech, pictures and other data invisibly through air.” [Bellis] Majority of technology uses electromagnetic waves to send data information or TV broadcasts. During the 1860’s, Scottish physicist, James Clerk Maxwell predicted the existence of radio waves; and in 1886, German physicist, Heinrich Rudolph Hertz showed how fast the variation of electric current could be placed into space in the form of

There is a wide range of communications technology that is used by the Public Services. Every Public Service uses some form of technological equipment as it is vital to carry out their duties effectively and efficiently. Depending on what job they are required to do, they will use different types of technological equipment. Communications technology being, The Police National Computer, Roaming network, Radios, Cormorant digital voice, Local Area Network and Satellite communications.

You might not have known that there is a difference between walkie-talkies and two-way radios. They appear to be the same. They can trasmit signals, but the way in which they transmit is completely different. Ham radio and CB radio are another communication system that people can be confused about, but to speak knowledgably about the topic, you should know the difference.

Once the transformer sends out the radio signal, it is sent to the crystal oscillator which is another important part. The oscillator makes an electromagnetic frequency by vibrating a piece of crystal. Once it is modified by the oscillator, the signal is complete and ready to be broadcasted.

One of the most important contributions to communication is the invention of radio communication. It has provided a platform for wireless cellular communication. According to an article, it was first believed that ‘The wireless telephone will also cover the seas, lakes and waterways, supplementing the wireless telegraph over short distances’ (Burt, 1908, para. 3). If only he knew that wireless telegraph will become a thing of the past. The first effective radio communication system was developed by Guglielmo Marconi, an Italian inventor, and scientist (Guglielmo Marconi Biography, n.d.). Marconi never had any formal scientific education (Bababian, 1992), but ‘has been the recipient of honorary doctorates of several universities’ (Guglielmo Marconi - Biographical, 2013, para. 8). He began experimenting with electromagnetic waves in 1894 when he was twenty years old. However, ‘Nikola Tesla is now credited with being the first person to patent radio technology; the Supreme Court overturned Marconi's patent in 1943 in favour of Tesla. (Bellis, n.d., para. 6) ’.

The best technology system for the Naval Academy would be the 802.11a standard. It has 54 Mbps throughput capability as well as adequate range, sufficient for classroom use. Since the 54 Mbps is shared amongst all users, it would allow, at a minimum, 2 Mbps for each user in a class of 20 midshipmen operating simultaneously. It also has higher data rates at comparable distances

With the recent surge in wireless communications, the radio industry has seen an increase in the number of different communication standards each requiring its own specific hardware and processing. Our project addresses the need for radio interoperability with these various standards through the development of hardware generators for a software defined radio (SDR) system. These hardware generators will be created using Chisel, a hardware construction language. When given a set of parameters or constraints, the hardware generators will automatically output circuit designs for the given application thereby accelerating the hardware design process and introducing a new method for multi-standard support. Specifically, our team will focus on the development of generators for the system’s beamforming and MIMO blocks.

Wireless technology is widely used throughout different countries and governments, and is one of the most fast-growing and needed technologies on the market today. While in the past it has been looked at as something that is not needed, now is necessary. Most companies have main business functions that occur outside the main office, and taking a laptop computer into the field helps the need to complete services particular to that business. Globally, the wireless field is expanding and both people and business are beginning to heavily depend on its services all over the world. Wireless technology has also become more popular in the field of education and is being taken in by not only university

A growing expansion of wireless systems and applications operating at centimetre-and millimetre-wave frequencies motivates the development of effective and affordably-priced technologies for manufacturing cm- and mm-wave components like antennas, filters, directional couplers, etc. Advances in technology associated with signal processing, R.F. components and batteries have stimulated more innovative applications in wireless that has in turn stimulate for extensive research to find new solutions to the problems in the antenna engineering.

We all have one life to live. In this life we teach things to others, but we also learn things from others. We communicate in one way or another to get across with our purpose whatever it might be. We all have our own communication style, way to listen, communication apprehension, and our way to resolve conflict. Therefore, I will elaborate in those concepts with my own personal experience and understanding about them.

frequency offsets in the subcarriers, the orthogonality among the subcarriers breaks and this causes intercarrier interference (ICI). The second drawback, is that

Basic elements of communication must be meet to have success. Great communication is the key in creating a more connected system for the administration managements. Karl Weick defines the organizational process as, “A method to resolve ambiguities’ through the collective processing of information” (94). Any agency, firm, police, court or correction must use this method to define their system of communication. Management has the duties of setting boundaries and rules for communication. This will allow them to function effectively and meet their organizational goals (Stojkovic, Kalinich, and Klufas).

Wireless technology is a booming business that is finding far reaching benefits on a global level. Corporations, schools, homes, and cafes are implementing wireless solutions as individual organizations and users seek more freedom and constant access. Wireless Fidelity (WiFi) is the latest buzzword to capture the market in our individual quest for access anywhere at any time. All of this comes at a price. Security is a major concern moving forward, as well as having too much access that does not lead to needed personal downtime. In the end what is more valuable, access or secure access at the right time?

modern communication devices, and day-to-day communication is done through it. Study of literature of past few year shows that, the leading work on Microstrip Patch Antenna (MPA) is focused on designing for dual frequency and dual polarized operation on arbitrary shape of patch with commercially simulated software. This review paper demonstrates some commonly engaged techniques to fabricate Microstrip patch antenna with dual frequency and dual polarized operation since last few decades. Index Terms - Patch Antenna, Simulator Software, Frequency, Polarization, Gain. I. INTRODUCTION Microstrip Patch Antenna (MPA) is commonly used because of its low profile, low cost and ease of manufacturing.
