Systems and Methods for Broadcasting Unsolicited Management Frames After a Channel Switch

A wireless device, comprising:

• a processor;
• a wireless interface configured to communicate with an access point;
• and
• a memory communicatively coupled to the processor, wherein the memory comprises a channel switch logic that is configured to:
• receive, from the access point, a channel switch announcement indicating a switch from a first channel to a second channel;
• calculate a ready time for the second channel;
• transition the wireless interface to the second channel to wake up at the calculated ready time;
• receive an unsolicited management frame from the access point on the second channel;
• and
• resume data transmission.

A method of efficient channel switching, comprising:

• determining, by an access point, that a channel switch from a first channel to a second channel should occur;
• calculating, by the access point, a max channel switch time;
• transmitting a channel switch announcement;
• switching at least one radio of the access point to the second channel;
• and
• scheduling for transmission, by the access point, an unsolicited management frame on the second channel.
