2. The IEEE 802.11n:- The IEEE 802.11n standard, appear in 2008, And become popular because the jump in data transfer rates from about 54 Mbps to nearly 600 Mbps. The IEEE 802.11n standard was officially completed in 2009 but most of the technical features were ratified in 2007. Most companies supported for the creation of a 60 GHz based standard for WLANs to succeed the 802.11n standard, and a lot of attention and effort was devoted to this activity. However, it was soon realized that the 60…

How satellites have been used to help society? A satellite is a space body which has been created by colliding of two or more space objects (for ex. meteorites). There are two types of satellites: natural satellites (like moon, an earth’s satellite) and man-made (artificial), satellites launched to the orbit by people. Natural satellites A natural satellite is space body that orbits another space body bigger than itself. Natural satellites are not man-made satellites. They come from space…

that was connected to a cord and the wall. So when people wanted to talk, they would have to wait standing for the person to finish and for the phone to be available. A couple of years later there was the portable phones where they had the antenna connected. The phone wasn't touch screen. You couldn't even text someone through it. They were pretty expensive and heavy to be carried around so, a lot of people wouldn't have it. After those the flip phones were born.…

they are not aquatic The American is originally for Africa and migrated here hundreds of years ago. Their original habitat for american roaches were in hot and humid places but have adapted to cold places. Americans are a reddish brown color with antenna. Females have shorter wings than males, males wings go past there abdomen. They are around 1.5 inches long. The female lives about one year, long enough to lay eggs.The eggs are laid in bean shaped sacks hidden under things to protect them.…

experience with the world’s first human cyborg, Neil Harbisson. In Max’s encounter with Harbisson, he portrays Harbisson as a hipster who has an antenna arching from the back of his skull. Max’s personal conversation with a real cyborg alone can answer the question regarding humans shaping their own evolution. Max explains to the reader how Harbisson’s antenna allows him to turn color into frequencies that he can hear. The fact that Harbisson has exceeded human skills provides key evidence that…

require direct alignment. A benefit of the high frequencies and short wavelengths in microwaves is the ability to direct the signal by shaping the antenna like a dish to focus, aim, and receive the data signal efficiently. The nature of the shaped antenna by focusing the signal and sending the signal in a parallel path to a receiving shaped antenna, negate some of the affects of diffraction. Satellites in geosynchronous orbits require the highest levels of power to transmit data signals to…

done with a mobile device. Having a cell phone does make things much easier, but everything comes with a price. Studies showed that cell phones emit radiofrequency energy (radio waves), a form of non-ionizing radiation, from their antennas; tissues nearest to the antenna can absorb this energy (Ahlbom A, Green A, Kheifets L). These energies that are…

through my suit like a bullet through butter and I felt the worst pain of my life as it ripped open my side… The last thing I remember was seeing Johanssen hopelessly reaching out toward me.” (p. 5) Mark Watney had no control over whether or not the antenna would hit him. The colossal dust storm that attacked the Ares-3 crew was an unforeseen and unexpected event. As a result, there was no precautionary measure that Mark Watney could have taken to prevent him from getting impaled.…

If every signal has its own frequency range, then multiple signals can be transmitted simultaneously over a single channel transmit multiple signals simultaneously over a single channel at different frequency ranges. • Reduced antenna…
