Cognitive Radio Essay

In the short story by John Cheever called "The Enormous Radio" it begins with Jim and Irene Westcotts appearing like the perfect American family. Cheever describes them as "the kind of people who seem to strike that satisfactory average of income, endeavor, and respectability" (Cheever 1). What is ironic about this story is the Westcotts are far from being the perfect family and the community they try to conform to is just as imperfect as the Westcotts themselves. A way the Westcotts try to live up to their society is by keeping secret the fact that they listen to the radio and attend musical events. This is because these activities were not something members of their community did. For example, Cheever says the "Westcotts differed

In comparison to other radio systems, multi-site trunked radio systems provide the best coverage. Multi-site

Spectrum sharing: Since there may be multiple CR users trying to access the spectrum, their transmissions should be coordinated to prevent collisions in overlapping

Handheld radios will be used as the primary communication device. Each radio will be fully charged prior to the event, and set to channel 1.

Radio was a very important transmission mode. The radio’s main function was to deliver citizens the necessary information in a way that was easy to understand, while at the same time making sure the news agencies earned sufficient ratings and to profit. The radio companies had to make the radio programming easy to understand to the average citizen, because “[t]he education of many Americans had ended after freshman year in high school. (Horten, p.

In the underlay approach, secondary users should operate below the noise floor of primary users, and thus severe constraints are imposed on their transmission power. Ultra-wideband (UWB) technology is very suitable as the enabling technology for this approach. In spectrum overlay CR, secondary users search for unused frequency bands, called white spaces, and use them for communication.

It's the only weather station in it's class that uses frequency hopping spread spectrum radio technology translating weather data wirelessly

   John Cheever’s "The Enormous Radio" represents the enormous amount of hidden truths in American society of the 1940s. The problems with society during this time were hidden behind a facade of goodness; however, this false innocence becomes visible through the radio owned by the Westcotts. The radio causes the Westcotts to evolve from an innocent, naive pair who believe that everything they see is real, into individuals who realize that appearances are deceiving.

This Radiolab is talking about whether human and other species can communicate each other or not.

    Many authors use the personification of inanimate objects to symbolize the feelings and expressions of their characters. One example of this is in John Cheever’s short story, "The Enormous Radio." Although critics argue that the characteristics of the radio are the opposite of those of Jim and Irene Westcott, the radio actually reflects the couple’s life.

Opponents of the reallocation, mainly broadcasters argued that wireless carriers were not using the spectrum efficiently and they had alternatives to increase the capacity of the spectrum without reallocation. Gordon H Smith (President of The National Association of Broadcasters(NAB)) said that more investment in towers and infrastructure and receiving standards could maximize the large range of spectrum already allocated to them. They also did a study and released its findings that the FCC did not take into account all the various ways that wireless carriers could increase the capacity of the spectrum they already allocated. They pointed that increase use of femtocells, improved receiver standards and spectrum sharing will do the purpose. They were also concerned about the fact that the FCC could simply not renew the licenses for the broadcaster`s spectrum and they may just reallocate the spectrum for wireless broadband carriers. They were also concerned if they sue FCC, but the result may come only after a long time. Eventhough the spectrum offering by the broadcaster is voluntary, they think it may not the case in reality.

CB operators, or citizens band radio operators, are people who are only loosely regulated by government oversight. Anyone in the general public can jump onto a CB radio and talk to anyone within the U. S. at any time. CB equipment has a limited range and are only able to transmit at five watts, which limits how far the signal can travel. At five watts, it's only a few miles. They are also restricted to the 27 MHz band.

The radio is one of the most influential pieces of technology ever invented. From political debates to Taylor Swift’s latest hit, with the help of the radio, society stays informed on a plethora of topics. Freddie Mercury wasn’t lying when he said, “and everything I had to know, I learned it on my radio.” In almost every country in the world, there is at least one radio station used to broadcast news to it’s people. Since the creation of the FM radio, it has been used to reach out to people over a certain area and keep them informed about the society they live in. During the 1930s and the 1940s, the radio played a very important role in history; it was a tool used during World War II by America, Great Britain, and Nazi Germany. By sending
