Nextiva S4200 Series User Guide
Here is an example of a 23 dB signal difference between channels 8 and 9 in the 4.9 GHz
band:
Consider the following setup in the 4.9 GHz band with 5-MHz bandwidth, where Cell B uses
channel 6 and you are trying to add Cell A on channel 3 (adjacent to channel 6):
To determine if this setup is feasible, you need to conduct a site survey on device A1 (the
master device in Cell A), then calculate the signal difference between the two cells. During
the site survey, device A1 will find the other five devices. With the provided signal levels,
you need to check if S2 - S1 <= Max, where:
S1 is the lowest signal level in the wireless cell of the device performing the site survey
(A1 in the example).
S2 is the highest signal level in the adjacent cell (Cell B in the example).
Max is the maximum signal difference (23 dB for a 6 Mbps bit rate in the example).
To calculate the emission signal difference between two adjacent wireless cells:
1. Open SConfigurator, then click the Units tab.
2. Select the master device in the wireless cell you are adding, then click Telnet.
