What do red or yellow lines signify in the Wireless Coverage Map?

In the context of a Wireless Coverage Map, red or yellow lines specifically indicate that there is a channel conflict between two devices. Channel conflicts occur when multiple devices are trying to use the same frequency or channel for transmission, leading to interference and degraded performance in the wireless network. By marking these conflicts with red or yellow lines, the coverage map effectively highlights areas where the signal quality may be compromised due to overlapping signals, allowing network administrators to take action to mitigate these issues, such as changing the channel assignments or repositioning devices for optimal performance.

A strong connection, normal operation without issues, and devices being out of range would not be represented by red or yellow lines, as those would typically reflect optimal performance (often shown in green) or simply indicate lack of coverage, rather than direct interference.
