Bluetooth
Bluetooth hops across the 2.4 GHz 1,600 times a
second, which is a form of frequency-hopping spread
spectrum (FHSS) modulation.
Due to the nature of frequency-hopping transmitters,
they may cause WLAN degradation, though it is
unlikely that Bluetooth will cause severe Wi-Fi issues.
Customize the Utilization Threshold
Wireless engineers need to know how often noise levels cross a threshold. The Utilization or frequency
utilization is a calculation that determines how much activity on a certain frequency occurs above the threshold.
Utilization answers the question, “In the past five minutes, what percentage of time was noise above -90dBm?”
When planning, engineers must set a threshold that matches the SNR (Signal to Noise Ratio) requirements of
their WLAN.
Adjust the Utilization Threshold to -90dBm
In the Chanalyzer File menu, click File > Preferences.
The bottom of the preferences window contains an
adjustable Utilization threshold. Set this value to -90dBm.
Open 2.4 GHz 802.11g on Channel 6.
Select the Showcase Tab in the Details pane. Click the
right arrow until the “2.4 Ghz 802.11g on Channel 6”
recording appears.
Press the Play button.
Click on the Utilization tab in the bottom pane.
Change the Utilization Threshold to -80dBm
