Claims (27)

1. Multiband communication device, containing a transmitter that, in operation, transmits, in a frequency band in a wireless network, to the multiband communication devices, frames that include activities related to said frequency band and at least one other frequency band in which the multiband communication device is transmitting; and a receiver that, in operation, receives in said frequency band in a wireless network from multiband communication devices frames that include actions related to said frequency band and to said at least one other frequency band in which the multiband communication device receives. 2. The multiband communication device of claim 1, wherein the in-band frame activities include authenticating multiband communication devices in said frequency band and in said at least one other frequency band of the multiband communication device. 3. The multiband communication device of claim 1, wherein the actions in the frames in the frequency band include associating or reassociating multiband communication devices in said frequency band and in said at least one other frequency band of the multiband communication device. 4. The multiband communication device of claim 1, wherein the actions in the frames in the frequency band include deauthenticating the multiband communication devices in said frequency band and in said at least one other frequency band of the multiband communication device. 5. The multiband communications device of claim 1, wherein the in-band frame operations include deassociating multiband communications devices in said frequency band and said at least one other frequency band of the multiband communications device. 6. The multiband communication device according to claim 1, which is a multiband access point (AP) and stores a single association record for the multiband communication device that is applicable to the specified frequency band and to the specified other frequency bands. 7. The multiband communications device of claim 6, wherein the single association record for the multiband communications device includes an association state variable, an association identifier (Association ID, AID), and security keys. 8. Multiband access point (access point, AP), containing a transmitter that, in operation, transmits frames to non-station access points (STAs) in a single wireless network that simultaneously operates in a plurality of frequency bands; and a receiver that, in operation, receives frames from non-station access points (STAs) on a single wireless network that simultaneously operates on multiple frequency bands. 9. The multiband access point of claim 8, wherein one wireless network is identified with a single Basic Service Set Identifier (BSSID) across multiple frequency bands. 10. The multiband access point of claim 9, wherein the basic service set identifier is the MAC address of the wireless interface in any of the plurality of frequency bands. 11. The multiband access point of claim 8 that communicates with a non-station access point in one or more of the plurality of frequency bands upon successful association of the non-station access point in a particular one of the plurality of frequency bands. 12. The multiband access point of claim 8, wherein all beacon and probe response frames transmitted by the multiband access point in multiple frequency bands advertise the same basic service set identifier (BSSID). 13. Communication method, including receiving by an access point (AP) in the same frequency band in a wireless network from non-AP stations (STAs) request frames that request authentication and association of non-AP stations in the many different frequency bands in which the access point operates in a wireless network; and transmitting, from the access point to the non-access point stations, response frames in said single frequency band which authenticate and associate non-access point stations in the plurality of different frequency bands in which the access point operates in the wireless network. 14. The communication method of claim 13, further comprising transmitting, from an access point in a wireless network, to non-access stations in said single band, beacon frames and probe response frames that announce that the access point is operating in a variety of different frequency bands that include at least two of 2.4 GHz, 5 GHz and 6 GHz. 15. The communication method of claim 13, further comprising transmitting, from an access point in a wireless network, to non-access stations in said single band, probe response frames that announce that neighboring access points operate in a plurality of different frequency bands. . 16. A multiband communication device for communicating with multiband communication devices, comprising: a processor that, in operation, generates frames that include actions related to the first frequency band and at least one other frequency band in which the multiband communication device is transmitting; and a transceiver that transmits frames in the first frequency band during operation. 17. A multiband communication device for communicating with a multiband communication device, comprising a receiver that, in operation, receives frames that include actions related to the first frequency band and at least one other frequency band in which the multiband communication device is transmitting; and a processor that, in operation, generates frames in response to receiving frames.
