Each answer is worth 7 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?

It can be found in the middle panel, the topographical view, in this case around -95db at 2.4Ghz.

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

The signal level of the noise floor is at -95db at 2.4Ghz and -100db at 5Ghz.

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

Of the 11 channels, it looks like channel 10 and 11 have the lowest noise floor range.

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

Yes, as you can see across channels 4 thru 8.

5. If it is, what type of signal is this, 900 MHz, 2.4GHz, or 5 GHz?

Signal is in the 2.4Ghz range.

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

Yes

7. If it is, what type of signal is this, 900 MHz, 2.4GHz, or 5 GHz?

The 2.4Ghz range.

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?

In the adjacent-channel.

9. On what channel has this interference appeared on?

Looks to be around channel 4 or 5.

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

This interference seems to peak at a higher range between channel 4 and 5 and is stronger than channel 6, which is the range it is interfering with.
