Samsung patents method to sync Wi-Fi frequencies between access points
Samsung describes a way for multiple Wi-Fi routers (access points) to coordinate their signal frequencies. One router sends a reference signal, and another adjusts its frequency to match it, ensuring they operate in sync.
In the filing’s own words
A system and a method are disclosed for carrier frequency planning in beamforming. The method comprises transmitting, with a first access point (AP 1), an AP1 frequency reference frame at an AP1 carrier frequency f c1 and obtaining, with a second access point (AP 2), a synchronized AP 2 carrier frequency f c2 based on the AP1 carrier frequency f c1. The method further comprises transmitting, with the AP 2, an AP 2 frequency alignment frame using the synchronized AP 2 carrier frequency f c2. Also disclosed are system and methods for sounding results reuse.
What exactly they claim (claim 1)
1. A method comprising: transmitting, with a first access point (AP 1), an AP 1 frequency reference frame at an AP 1 carrier frequency f c1; obtaining, with a second access point (AP 2), a synchronized AP 2 carrier frequency f c2 based on the AP 1 carrier frequency f c1; and transmitting, with the AP 2, an AP 2 frequency alignment frame using the synchronized AP 2 carrier frequency f c2.
