A city Wi-Fi coverage map labels a 'primary channel' on an 80 MHz BSS. What does that label mainly communicate?
Select an answer to reveal the explanation.
Short Explanation
An 80 MHz 'fat pipe' still has a main street address — the primary channel — where a lot of the control chatter lives. The wider spectrum is the boulevard; the primary channel is the street sign you navigate by.
Full Explanation
Wide channel widths (for example 40/80/160 MHz class operation) aggregate spectrum, but 802.11 still designates a primary channel for critical management and control behavior. Maps and recon notes that show the primary channel help assessors tune captures and understand BSS operation. The primary channel is not a VLAN ID or a WEP leftover; it is the anchor channel within the wider BSS bandwidth.
