Part 11: Pick A Transmission Medium Type, E.g., Copper Fiber

Part 11 Pick A Transmission Medium Type Ie Copper Fiber Wireles

Part 11 Pick A Transmission Medium Type Ie Copper Fiber Wireles

PART 1: 1. Pick a transmission medium/ type i.e. copper, fiber, wireless - what do you suppose is the biggest communication challenge is with that medium? 2. What do you suppose are the biggest communication challenges in these environments below? (Can be multiple "correct" answers. Provide your best guess and also address why you picked that.) A. Equipment Factory B. School Building C. Hospital D. Outdoor wireless link

PART 2: We are learning about error correction, cross talk, interference and noise. For each Media type below (twisted pair, fiber optic, wireless), you are going to be asked about what causes the errors/what types of errors are typically see, and then what you can do to attempt to correct those errors. Remember, errors in communication can include one or all of: Impulse noise, Crosstalk, Echo, Jitter, Delay distortion, Attenuation

Twisted Pair: 1. What types of errors are most commonly found in twisted pair cable? 2. What can be done or is done regularly to combat those errors or eliminate them all together on a given segment?

Fiber Optic: 1. What types of errors are most commonly found in fiber optic cable? 2. What can be done or is done regularly to combat those errors or eliminate them all together on a given segment?

Wireless: 1. What types of errors are most commonly found in wireless communication? 2. What can be done or is done regularly to combat those errors or eliminate them all together on a given transmission?

COM270 – In-class Assignment Part 1: Summary descriptions of the 34 talents measured by the Clifton StrengthsFinder® assessment Themes © 2000, Gallup, Inc. All rights reserved. This is not a test -- there are no right or wrong answers. Everyone has a different combination of strengths. Read all the descriptions first so that you will be aware of the range of strengths described here. Go back through the themes. Circle Y for “Yes” only when a theme strongly resonates with you, either because you know it about yourself or because others have described you in this way. Circle S for “Sometimes” when you show this strength, but you know it is not a signature part of you. Circle N for “No” when you know that a theme doesn’t really describe you. Remember, no theme is “better” than another. No one will see this sheet except you. When you are done, review your choices. Circle at least four and no more than six strengths that describe you the best.

(Themes list omitted for brevity.)

Part 2: Four domains of individual strength Domains © 2009 Gallup, Inc. All rights reserved. Check off your four to six selected strengths here. Your strengths may be distributed across the columns or may be concentrated in one or two columns – again, there is no right or wrong answer.

(Strengths selection omitted for brevity.)

Part 3: Your internal analysis Write some notes on a piece of paper (not on a computer screen!) about your profile. Think about the “strengths domains.” Are you predominantly in one or two domains, or in several? Did the groupings of strengths give you any additional insight about your set of strengths? Think specifically about stories or examples from your life that “prove” your choices. Think about times that you’ve been told you exemplify a certain trait; consider the different people who’ve told you this, and in what settings. If it applies, think about times you’ve been teased for a trait (for example, being a compulsive list-maker, or being able to talk to anyone you meet). Ponder how this trait can actually be a strength in a particular work setting. Finally, refine all this analysis into three sentences that best describe you as a person. Don’t write, “I am an Activator who makes things happen….” These sentences need to be in your own words; if you use a theme word such as “strategic” it must not be capitalized if it is used in mid-sentence. The two important parts of this exercise are for you to begin to think actively about how you can describe yourself, and for you to organize your thoughts before you begin to write about them. Don’t skip this step.

Part 4: The writing assignment (submit this where indicated online—not the rest, though; keep them for your own use) Using the three sentences you wrote as a guide, write an approximately 500-word description of your strengths (double-spaced is fine) and attach it online where indicated. In your opening paragraph, briefly describe your experience with the exercise – specifically, whether it was easier or more difficult to identify and narrow down your three main strengths. In the body of the assignment, describe yourself in a way that someone who doesn’t know you would gain a good understanding of your natural talents. You can certainly use the three sentences you developed. You must illustrate your paper with strong examples or stories from your life (work, school, or personal). Conclude by describing what your talents tell you about your career -- what insights did this assignment give you about what your career? What will you have to offer an employer?

Paper For Above instruction

The chosen transmission medium for analysis is wireless technology, which presents unique communication challenges. While wireless communication offers flexibility and convenience, it faces significant hurdles such as interference, signal attenuation, and security vulnerabilities. These issues can disrupt data integrity and delay transmission, impacting overall system performance.

In wireless environments like outdoor links, interference from other electronic devices and physical obstructions are predominant challenges. In indoor settings such as hospitals and school buildings, interference from competing signals, structural barriers, and electronic equipment can significantly degrade signal quality. Equipment factories, with their heavy machinery emitting electromagnetic noise, also pose substantial interference issues affecting wireless transmission.

Regarding error correction, cross talk, interference, and noise, each medium type exhibits distinct error profiles and correction strategies. Twisted pair cables commonly experience impulse noise, primarily caused by nearby electrical devices, and crosstalk resulting from electromagnetic interference between pairs. To combat these errors, twisted pair lines often employ shielding, twisted configurations, and error detection protocols like cyclic redundancy checks (CRC), which help identify and correct errors.

Fiber optic cables generally face errors such as attenuation, which results from signal loss over distance, and dispersion, which causes pulse spreading and potential data corruption. To mitigate these issues, techniques like optical amplifiers and repeaters are used, along with precise manufacturing and installation practices that reduce defects and impurities in the fiber.

Wireless systems are most affected by errors like impulse noise, caused by electromagnetic interference from various sources, and multipath interference, where signals bounce off structures, creating echo-like distortions. Methods such as frequency hopping, spread spectrum technologies, and error correction algorithms like forward error correction (FEC) are regularly employed to address these problems, maintaining data integrity over unreliable channels.
