Which Spectrum Analyzer plot would show the percentage of time a signal is measured at a particular frequency?

Explain the protocol behavior that can be known in the following graphic?

You have been hired to troubleshoot a WLAN problem for a government organization. You intended to use a Protocol Analyzer as part of your troubleshooting methodology; however, the customer is concerned about you capturing sensitive data transmitted over the network. Which common protocol analyzer feature could you use to address this concern?

Your organization would like to give their network field engineers a tool to provide an overview of a given wireless LAN environment. They are interested in how many SSIDs are enabled per radio, channels used, and the number of APs per channel. They do not want to require the engineers to view multiple frames to determine the information. Which tool would you recommend that provides this information at the lowest cost?

You are troubleshooting an intermittent problem with some WLAN VoIP phones resulting in dropped calls. You configure your capture on a fixed channel matching the current operating channel of a test phone. So far, you have been unsuccessful in capturing the problem because the VoIP phone always roams to another AP before the problem occurs.

What would be the best setup for your packet capture to make sure you capture the problem?
