1. A first device for wireless communication, comprising:

a processor, a memory, an input, an output, an antenna, and a wireless communication unit, the first device including a plurality of media-access-control (MAC) addresses and being configured to communicate over first and second wireless communication frequency bands, wherein the first device is to:

transmit, over the first wireless communication frequency band to a second device using a first one of the plurality of MAC addresses, an information element (IE) having (a) a MAC address indicator field to identify whether the IE includes a MAC address field and (b) a timing synchronization function (TSF) offset field to identify a TSF offset value between the first and second wireless communication frequency bands;

select a second one of the plurality of MAC addresses associated with the MAC address field for identifying the wireless communication unit over the second wireless communication frequency band during a session with the second device when the MAC address indicator field has a first value; and

use the first one of the plurality of MAC addresses for identifying the wireless communication unit over the second wireless communication frequency band during the session when the MAC address indicator field has a second value.

2. The first device of claim 1 , further including transferring the session by transmitting a session-transfer request to the second device and receiving a session-transfer response from the second device.

3. The first device of claim 1 , further including receiving a session-transfer request from the second device and transmitting a session-transfer response to the second device.

4. The first device of claim 1 , wherein the first wireless communication frequency band includes one frequency band selected from at least one of a 60 gigahertz frequency band, a 2.4 gigahertz frequency band, or a 5 gigahertz frequency band, and wherein the second wireless communication frequency band includes another frequency band selected from at least one of the 60 gigahertz frequency band, the 2.4 gigahertz frequency band, or the 5 gigahertz frequency band.

5. The first device of claim 1 , wherein the first device includes at least one of: 1) a keyboard, 2) a screen, or 3) an audio speaker.

6. The first device of claim 1 , wherein the first one of the plurality of MAC addresses is different than the second one of the plurality of MAC addresses.

7. A method of wireless communication, comprising:

transmitting, from a first wireless communication device over a first wireless communication frequency band to a second wireless communication device using a first one of a plurality media-access-control (MAC) addresses, an information element (IE) having (a) a MAC address indicator field to identify whether the IE includes a MAC address field and (b) a timing synchronization function (TSF) offset field to identify a TSF offset value between the first wireless communication frequency band and a second wireless communication frequency band;

selecting a second one of the plurality of MAC addresses associated with the MAC address field to identify a wireless communication unit of the first wireless communication device over the second wireless communication frequency band during a session with the second wireless communication device when the MAC address indicator field has a first value; and

using the first one of the plurality of MAC addresses to identify the wireless communication unit over the second wireless communication frequency band during the session when the MAC address indicator field has a second value.

8. The method of claim 7 , further including transferring the session by transmitting a session-transfer request to the second wireless communication device and receiving a session-transfer response from the second wireless communication device.

9. The method of claim 7 , further including receiving a session-transfer request from the second wireless communication device and transmitting a session-transfer response to the second wireless communication device.

10. The method of claim 7 , wherein the first wireless communication frequency band includes one frequency band selected from at least one of a 60 gigahertz frequency band, a 2.4 gigahertz frequency band, or a 5 gigahertz frequency band, and wherein the second wireless communication frequency band includes another frequency band selected from at least one of the 60 gigahertz frequency band, the 2.4 gigahertz frequency band, or the 5 gigahertz frequency band.

11. The method of claim 7 , wherein the first one of the plurality of MAC addresses is different than the second one of the plurality of MAC addresses.

12. A non-transitory machine-readable storage medium having instructions stored thereon, wherein the instructions, when executed by a machine, cause the machine to perform operations comprising:

transmitting, from a first wireless communication device over a first wireless communication frequency band to a second wireless communication device using a first one of a plurality of media-access-control (MAC) addresses, an information element (IE) having (a) a MAC address indicator field to identify whether the IE includes a MAC address field and (b) a timing synchronization function (TSF) offset field to identify a TSF offset value between the first communication frequency band and a second wireless communication frequency band;

selecting, by the first wireless communication device, a second one of a plurality of MAC addresses associated with the MAC address field for identifying a wireless communication unit of the second wireless communication device over the second wireless communication frequency band during a session with the second wireless communication device when the MAC address indicator field has a first value; and

using the first one of the plurality of MAC addresses for identifying the wireless communication unit of the second wireless communication device over the second wireless communication frequency band during the session when the MAC address indicator field has a second value.

13. The medium of claim 12 , further including transferring the session by transmitting a request to the second wireless communication device and receiving a response from the second wireless communication device.

14. The medium of claim 12 , further including receiving a request from the second wireless communication device and transmitting a response to the second wireless communication device.

15. The medium of claim 12 , wherein the first wireless communication frequency band includes at least one of a 60 gigahertz frequency band, a 2.4 gigahertz frequency band, or a 5 gigahertz frequency band, and wherein the second wireless communication frequency band includes another of the 60 gigahertz frequency band, the 2.4 gigahertz frequency band, or the 5 gigahertz frequency band.

16. The medium of claim 12 , wherein the first one of the plurality of MAC addresses is different than the second one of the plurality of MAC addresses.
