Two identical municipal APs are mounted with different cable runs, and a technician wonders whether phase matters when those signals combine at a client. What does phase describe?

Short Explanation
Picture two kids jumping on a trampoline — if they land together, you get a bigger bounce; if they land opposite, it cancels. Phase is where each wave is in its cycle when they meet. Cable delay can shift that timing so the client sees help or a hole.
Full Explanation
Phase is the relative position of an RF wave within its oscillatory cycle. When multiple copies of a signal arrive with different path or cable delays, their phase relationship determines constructive or destructive interference at the receiver. Phase is not a power unit, not channel bandwidth, and not an SSID timer. At CWTS technician depth, the key idea is that phase influences how waves combine, not that the AP GUI offers a routine 'phase' checkbox.
