Place the answers below the questions.

1. There are three patterns outlined on the screen which one of these is identifying the noise floor?

Note: You are to give the PATTERN number (1 – 4), not state which panel or view it is shown in. Refer to the video named Recognizing the Noise Floor for this question.

The first pattern shows the noise floor

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

Note:   You are looking for the amplitude in dB. Refer to the video named Recognizing the Noise Floor for this question.

2.4GHz band noise floor is -95db, 5Ghz band noise floor is -100db

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

Note:   The tapering area on the far right edge is due to the fact that 2.4 GHz signal ends at channel 11. Observe the area to the right of channel 1 and the left of channel 11. Refer to the video named Recognizing the Noise Floor for this question.

Channels 8-11 have the lowest noise floors

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

Note: Refer to the video named Recognizing Unlicensed Bands Signals for this question.

Yes it is

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

Note: Refer to the video named Recognizing Unlicensed Bands Signals for this question.

2.4Ghz

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

Note: Pay attention to the signals shapes in the video. Refer to the video named Recognizing Unlicensed Bands Signals for this question.

Yes it is

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

Note: Refer to the video named Recognizing Unlicensed Bands Signals for this question.

900MHz

8. In the area marked as Pattern 4 some...
