Samsung patents Wi-Fi routers that coordinate to test signal strength

Patent drawing
Patent drawing from the official filing.

Samsung describes a method where two Wi-Fi routers communicate to agree on when to test their signal quality. One router sends a request to the other, and they both confirm which specific signal checks they will perform to avoid interference.

Why it mattersThis could help improve the stability of home or office Wi-Fi networks by ensuring routers do not test their signals at the same time.

In the filing’s own words

Methods and systems for coordination between access points to perform selective channel soundings. A method includes transmitting a first frame to a second AP device, the first frame indicating that at least one of a first cross-basic service set (BSS) sounding of the first AP device and a second cross-BSS sounding of the second AP device is requested by the first AP device. The method also includes receiving a second frame from the second AP device, the second frame indicating acceptance of at least one of the first cross-BSS sounding and the second cross-BSS sounding requested in the first frame.
