Chapter 46: Using RF Analysis
SonicPoint > RF Analysis
This chapter describes how to use the RF Analysis feature in SonicWALL SonicOS Enhanced
to help best utilize the wireless bandwidth with SonicPoint and SonicPoint-N appliances. This
chapter contains the following sections:
• “RF Analysis Overview” section on page 591
• “Using RF Analysis on SonicPoint(s)” section on page 592
RF Analysis Overview
RF Analysis (RFA) is a feature that helps wireless network administrator understand how
wireless channels are utilized by the managed SonicPoints, SonicPoint-Ns and all other
neighboring wireless access points. This section contains the following sub-sections:
• “Why RF Analysis?” section on page 591
• “The RF Environment” section on page 592
Note SonicWALL RFA can analyze third-party access points and include these statistics in RFA
data as long as at least one SonicPoint access point is present and managed through the
SonicWALL appliance.
Why RF Analysis?
Deploying and maintaining wireless infrastructure can be a daunting task for the network
administrator. Wireless issues, such as low performance and poor connectivity are issues that
wireless network administrators often face, but ironically, these issues can usually be resolved
simply analyzing and properly tuning radio settings.
RFA is a tool that brings awareness to these potential wireless issues. The two main issues
which RFA deals with are overloaded channels, and AP interference with adjacent channels.
RFA calculates an RF Score for each operational SonicPoint and displays the data in a way
that allows the administrator to identify access points operating in poor RF environment.
