Each answer is worth seven points.

Use a red colored font for you answers.

Place the answers below the questions.

1. There are three patterns outlined on the screen which one of these is identifying the noise floor? The three view that we are able to see are Spectral View, Topographic View, and the Planar View. It is in the Topographic View where we can see the noise floor

2. What is the approximate signal level of the noise floor?

I wasn’t to sure fo which one I was suppose to but the video explained that the 2.4Ghz had band noise floor of -95db, and 5Ghz band noise floors was -100db

3. Of the 11 channels being displayed which ones have the lowest noise floor?

Channels 8-11 have the lowest noise floor

4. Inside the circle marked as Pattern 2 is this a signal from one of the three unlicensed fequency ranges? Yes it is

5. If it is, what type of signal is this, 900 MHz, 2.4GHz, or 5 GHz? It would be from the 2.4Ghs signal

6. Inside the circle marked as Pattern 3 is this a signal from one of the three unlicensed signal ranges? Yes it is

7. If it is, what type of signal is this, 900 MHz, 2.4GHz, or 5 GHz? This would be from the 900 MHz

8. In the area marked as Pattern 4 some interference has appeared. What type of interference is this, such as all-channel, co-channel, adjacent-channel? This is an Adjacent-Channel interference

9. On what channel has this interference appeared on? This is because channel 4 is interrupting with channel 6

10. Is this interference weaker than, the same, or stronger than the signal that was there before it appeared? It seemed to be the same strength.
