A method for switching between channels on different bands, the method comprising:
- communicating, by a subscriber station (STA), with a wireless device on a base channel;
- sending a channel switch request to the wireless device;
- receiving an acknowledgment from the wireless device;
- sending a test frame on a 60 GHz channel to determine channel characteristics of the 60 GHz channel before switching to the 60 GHz channel;
- and
- switching to the 60 GHz channel for communicating with the wireless device.
A method for switching between channels on different bands, the method comprising:
