Lab Report

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

Out of the three patterns I would say pattern 1 is the signal view for the noise floor.

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

It’s hard to be precise but I think the 2.4GHz band noise floor is between -90db and -95db. The 5ghz band noise floor looks to be between -95db and -100db

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

I would say during pattern 2 channels 1 – 4 have the lowest noise floor. During pattern 4 looks like 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, I believe so.

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

2.4GHz I think the flat top created by the sharp edged shoots are one of the characteristics of a 802.11n wireless signal.

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

Yes, I think it should be.

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

900MHz

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?

Adjacent Channel Interference which can only occur on a 2.4GHz band.

9. On what channel has this interference appeared on?

Channels 4 and 6 seem to share similar patterns.

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

The interference looks to be signals of the same size and wave strength.
