Introduction to Wireless LAN Analysis
RF Analyzers
An RF analyzer measures and displays details of the 802.11 PHY
Layer, which includes RF signals. For example, a spectrum analyzer
displays the amplitude of the signal over the frequency spectrum, which
is beneficial to identify the source of RF interference. Other RF
analyzers provide a variety of RF signal information, such as delay
spread, jitter, and phase shift. RF analyzers are generally necessary
when the protocol analyzer does not provide enough information to
solve an RF signal problem. Figures 1.3 and 1.4 are pictures of and
some screenshots from a popular RF analysis tool.
