The inability of the Yellowjacket b/a/n/g to display and alert the user to the presence of a major source of interference was also very surprising. The simple fact that you cannot quickly switch between scanning the 2.4 and 5GHz spectrums makes the Yellowjacket b/a/n/g a poor choice. I had hoped that this device would be comparable to the Cisco Spectrum Expert, AirMagnet Spectrum XT and the Metageek Wi-Spy dBx spectrum analyis tools.
I have yet to receive a response to my request for additional information to explain the unexpected behavior of the Yellowjacket b/a/n/g Wi-Fi spectrum analyzer.Īll in all, I was very disappointed in the Yellowjacket b/a/n/g device. I sent an email on to Berkley Varitronics Systems' email address asking about why the MAC display tab began to clear when I powered on the wireless security camera. To anyone with little spectrum analysis experience, the spike would not have stood out, and green usually means 'good'. The detected spectrum is shown as a green wave form, and there was a visible spike in the waveform, but the color of the spike was still green. If I were not experienced in using spectrum analysis tools, there would have been no real way for me to visibly discern that there was a source of interference that was critically impacting the 2.4GHz channel 6. It did, but since the screen is only 640 x 480, the entire 2.4GHz spectrum is shown quite small on the screen. When I switched over to the Spectrum tab to see if the wireless security camera showed a disturbance in the spectrum readout. I navigated through the different filter options for the MAC tab, and found nothing that I could select to show the list of MAC addresses again.
