Analyzing the RF Environment
An essential element in RF network planning is the analysis of spectrum usage and the
strength of the signals that occupy the spectrum you are planning to use. Regardless of
how you measure and log or chart the results you find (through the Spectrum Analyzer
feature or by using a spectrum analyzer), you must do so:
At various times of day.
On various days of the week.
Periodically into the future.
As new RF neighbors move in or consumer devices in your spectrum proliferate, this keeps
you aware of the dynamic possibilities for interference with your network.
Mapping RF Neighbor Frequencies
These modules allow user to:
Use a BHS or BHM as a Spectrum Analyzer.
View a graphical display that shows power level in RSSI and dBm at 5 MHz increments
throughout the frequency band range, regardless of limited selections in the
Custom
Radio Frequency Scan Selection List
parameter of the BHS.
Select a BHM channel that minimizes interference from other RF equipment.
The following procedure causes the BHS to drop any active RF link. If a link is dropped when the
spectrum analysis begins, the link can be re-established when either a 15 minute interval has
elapsed or the spectrum analyzer feature is disabled.
Analyzing the spectrum
To use the built-in spectrum analyzer functionality of the BH, proceed as follows:
